  • Running Mac Pro constantly - good or bad?

    Since I stream all my content to my apple tv, my Mac Pro runs all the time. In fact, I only restart it once every other month or so. Since it is always streaming, it never sleeps either (nor do I let it).
    Everything appears to be running normal, but I just want to make sure this is OK. It was quite an investment, and I need to know if I am decreasing the life of my Mac (or wearing anything out).
    Thanks.

    Most frequent answer to "run or sleep" overnight is: Set the monitor to sleep, let the system and hard drive run.
    But that answer is getting old because I don't think that, after 10.3, we need to leave the system run to run the chron scripts.
    Also consider: sleep versus shut down is choice of energy consumption (i.e., electric bills).
    I think you will find that there is little information about the effect of running a given Mac (or any computer we will likely own) constantly (for "x years") because- such computers are "by design" going to lose their usefulness before they "break down from over-use."
    Possibly a helpful example will clarify what I'm trying to say:
    In 1999, I bought an Apple LC II - made in 1993. I kept it running for a couple years - until the hard drive failed. It would have been simple to replace the hard drive and I could have kept it running even longer. But - that Mac was using OS 7.5.5! - So it was waay out of date and usefulness. Easier and more effective to just buy a new iMac (at the time).
    I got my eMac in Aug. 2003: it still runs, it is "adequate" for routine use and will probably remain so for a bit longer. Right now, it is in sleep mode in the next room. I have used that eMac at least 6 hours a day since I got it. (And it's been in screen-only sleep mode most of the rest of the time.) But when I want to "keep up" with Apple technology (and my own needs) - I have to buy a newer Mac with (in this case Intel) newer processor and newer version of operating system and newer versions of critical apps.
    "I wonder what the recommended procedure is for running a Mac Pro (or any Mac for that matter). Shutdown at night? Sleep at night?" --
    You may find a consensus or "average" answer to that question. I don't believe you will find the "definitive" answer because the Mac Pro is designed to satisfy a variety of personal and business needs. Ultimately: you should establish your own needs and set at least a rough "schedule" during which the Mac Pro is either in sleep mode or running.
    Sorry if I seem "vague" - but the above is per my experience. It's all probabilities in the end: probably, you will not have a problem caused by keeping the Mac Pro running "indefinitely." Be consoled the Mac Pro isn't limited to the "unitized" or all-in-one construction scheme; you can replace most vital parts in a Mac Pro yourself.
    Personally, I think if I continue keeping, maintaining and using my Mac Pro as I have my previous Macs, I will have this Mac Pro for even longer (4 or more years) than I had the earlier ones.
    Also - the "standard rule" for any Mac or PC is to keep backups of your data and to keep a bootable 2nd drive installed in case of emergencies. But you probably have heard that advice a dozen times already.

  • Is clean my mac any good, Is clean my mac any good

    Is clean my mac any good ?

    Hi nodnaj,
    If you like the app, fine, but it "gave" you nothing. Unwanted programs are easily found and disk space released using the Mac's normal methods. It is impossible for users to perform such damage on their own with the Finder. OS X won't permit it.
    Like most third party "cleaners", "scanners", and so forth, CleanMyMac has been known to remove system components that must not be removed. You'll be happy with CleanMyMac right up to the point at which it performs a lobotomy on your system. Make sure your backups are up to date.

    I want to clean my mac. what is best mac keeper or mac booster  or is there any recommended by Apple?

    Neither. I would stay away from any such software. Apple does not make recommendations for any software except their own.
    Kappy's Personal Suggestions About Mac Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utility is: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking. 
    Four outstanding sources of information on Mac maintenance are:
    1. OS X Maintenance - MacAttorney.
    2. Mac maintenance Quick Assist
    3. Maintaining Mac OS X
    4. Mac Maintenance Guide
    Periodic Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
    If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger.  (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
    Defragmentation
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. Malware Protection
    As for malware protection there are few if any such animals affecting OS X. Starting with Lion, Apple has included built-in malware protection that is automatically updated as necessary. To assure proper protection, update your system software when Apple releases new OS X updates for your computer.
    Helpful Links Regarding Malware Protection:
    1. Mac Malware Guide.
    2. Detecting and avoiding malware and spyware
    3. Macintosh Virus Guide
    For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
    Cache Clearing
    I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
    If you are using Snow Leopard or earlier, then for emergency cleaning install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
    Installing System Updates or Upgrades
    Repair the hard drive and permissions beforehand.
    Update your backups in case an update goes bad.
    Backup and Restore
    Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. You can never have too many backups. Don't rely on just one. Make several using different backup utilities. My personal recommendations are (order is not significant):
         1. Carbon Copy Cloner
         2. Get Backup
         3. Deja Vu
         4. SuperDuper!
         5. Synk Pro
         6. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
    Always have a current backup before performing any system updates or upgrades.
    Final Suggestions
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

  • Migrating assistant good or bad

    Hi guys...
    This is my first post so be gentle... I just have a small question for you guys and girls... what is your view on the migrating assistant, is it good or bad... i have heard someone saying that it migrates some files over that mess up your system... and if it does how do i know which to delete.. and second of all can you choose exactely what to bring over or does it just take everything... is targetdisk mode a better option... maybe a bit more timeconsuming but safer...?? Please give me your opinions... Thanks... ohh forgot to say, reason why im asking is that im planning on buying the infamous MBP..
      Mac OS X (10.4.6)  
    ibook g4 1.33   Mac OS X (10.4.6)   Really want MBP

    I would say that this is a WARNING [capital letters - if you can't tell already ;- ) ]
    My friend - who is a computer tech [Mac & PC] since the Apple II days. For all of you that don't know - that is 30 years ago. He bought his first BRAND NEW computer ever - yesterday - A MacBook Pro 2.16 w/ 7200RPM HD [off the shelf at a local Apple store]. He has made a LOT of money from repairing computers - he didn't have to buy this MacBook, because he has EVERYTHING else - he bought it because the MBP represented the ability to have the Mac OS + WIN XP on the same machine. And also - his clients were asking questions about the MBP, and he had to know - first hand, what they were about.
    He used the migration assistant to transfer his files from his PowerBook G4 - 17" [1.67MHz] - and there was disasterous consequences! After the transfer - the new MBP wouldn't boot to the desktop - until several restarts later. Finally when he could - there was some very weird stuff going on.
    1. No Airport recoginition
    2. Screen stayed on full bright [couldn't be dimmed]
    3. His BlueTooth cellphone would shut off [I know - this is crazy - but it is true, the MBP somehow killed the cellphone connection!]
    4. Kernel panics - [many]
    He [with 30 years experience] promptly returned the MBP to the Apple store - and showed it to the "Genius" - who immediately gave him a brand new one.
    He [or the "genius"] never had any reason to doubt the "integrity" of the "Migration Assistant". My friend thought that his MBP was defective - and the Apple "Genius" thought the same thing.
    So - he took it [the new one] home - and used the "Migration Assistant" again - and the exact same thing happened!
    Finally - he just decided to re-install the whole operating system [clean install] - and now everything is fine.
    If I were you - I wouldn't trust the "Migration Assistant".

  • How can I safely clean my Mac of old folders etc to make it run faster?er

    How can I safely clean my Mac of old folders, etc to make it run faster?

    The only real and safe way to do this is to do it manually  looking through each folder individually.
    Many third party utilities claim to clean out a hard drive of various detritus, but some times will delete data that it shouldn't  and delete any other  important data that it shouldn't have.
    The only "safe" way to accomplish what you need to accomplish is to do this manually.
    Stay away from the OS X system folder!!!!!
    Hard drive getting full?
    You can download an app called OmniDiskSweeper.
    This app will allow you to see where files maybe able to be delete are located.
    If your Mac is running a fairly recent version of OS X, here are some general guidelines.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your iMac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you have images stored in iPhoto,,the only way to weed out duplicates is to do this manually.
    When you delete them, they go to iPhoto's Trash. Remember to empty this when you are done.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what are duplicates and what isn't
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Other things you can do to gain space.
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!

  • Good or bad battery???

    hi
    i just bought a macbook pro 15" last week and im just wondering if i have a good or bad battery 'coz upon opening my macbook for the first time it suggested a lot of updates, including the battery update...so i did all updates...
    i charged my macbook fully last night and used it this morning...i checked my battery status and says 99%-2:55 remaining...then after 97%-4:11 remaining...
    i also check preferences....
    full charge capacity : 5489
    remaining capacity : 5407
    amperage : -1496
    voltage : 12294
    cycle count : 3
    i hope someone can enlighten me...
    thanks in advance...

    your stats seem ok.. i've gotten it as high as 142 hours temporarily, when its discharging.. the battery time to die measurement is at best an estimate..
    what were you running that you were drawing -1400 amps? thats a bit excessive...
    i run a problem called IBatt2 it has a grading system which compares your battery to the median of the same type of system battery... it will also show you the essential data...
    my battery with 45 cycles, gets a "C" grade on their system.

    It's not really malware but it is extremely poorly written software.  It has a fairly good user interface and is easy to use but, when the virus protection kicks in, it hogs all of the CPU resources and everything else slows to a crawl.  Consider thirty seconds merely to open a large folder.  I had it for several weeks and trashed it.  Also, trashing it is easy.  The old "drag to trash can" works just fine.

  • I'm new to mac. Is there a need for Clean my Mac?

    I'm new to mac. Is there a need to have Clean my Mac on my computer?

    How to maintain a Mac
    Make two or more backups of all your files
    One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.
    Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups.
    In fact, don’t rely exclusively on any single backup method, such as Time Machine.
    If you get an indication that a backup has failed, don't ignore it.
    Keep your software up to date
    In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
    Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
    Don't install crapware
    ...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
    It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.
    As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
    Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
    Don't install bad, conflicting, or unnecessary fonts
    Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
    Deactivate or remove fonts that you don't really need to speed up application launching.
    Avoid malware
    "Malware" is malicious software that circulates on the Internet. This kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.
    There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least one day ahead of the defense. You can’t rely on third-party "anti-virus" products for protection either. What you can rely on is common-sense awareness—not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
    Don't fill up your disk or SSD
    A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
    While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
    Relax, don’t do it
    Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
    A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products.

With very few exceptions, this stuff is useless, or worse than useless.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
    The free anti-malware application ClamXav is not crap, and although it’s not routinely needed, it may be useful in some environments, such as a mixed Mac-Windows enterprise network.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research.

Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much.

Don't install Java unless you're sure you need it. Most users don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.

Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

  • Any mac user use some kind of apps to "clean" your mac???

    i know that a lot of software are build for "CLEAN YOUR MAC", software like clean my mac, mac keeper, ccleaner. etc
    they all said that when we use our mac, there are a lot of "dummiy files " like language pack or used history .ect that need to be cleaned.
    if we dun clean it, it will make the system laggy.
    i know some ppl on the internet said its true,then other ppl said that all these softwares are jus malware, its totally unecessary to use all these.
    the mac ox system will clean itself.
    which one is true???
    did Apple claim or announce anything about these software???
    If its true,the softwares can clean your mac, how come all of these apps CANT go to Mac App Store???
    IF its true, you guys use what software to run the cleaning process???

    Macs do not need "cleaning". Apps such as the ones you mention have the ability to wreck your Mac.
    If its true,the softwares can clean your mac, how come all of these apps CANT go to Mac App Store???
    Because they are not safe to use.
    There are apps in the App Store that suggest the ability or necessity to "clean" memory or unwanted files. They are worthless and are only capable of degrading performance and wasting power. They will also waste your time and your money. Deleting localization files will cause problems and cannot be un-done without reinstalling OS X. Language files use a negligible amount of disk space.
    IF its true, you guys use what software to run the cleaning process???
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
    Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
    Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
    Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
    Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
    Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
    Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
    Don’t install Java unless you are certain that you need it:
    Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
    Disable Java in Safari > Preferences > Security.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
    Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
    Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
    The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
    OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
    Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
    If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
    Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
    Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
    Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

  • CLEAN YOUR MAC VIRUS

    I am REALLY p...d ! Seven months after i installed "clean your mac" this virus/malware (wich i bought from APPLE!!) my computer is STILL infected with this virus! After installing this MACKEEPER/ZEOBIT .... firm, it my mac went so slow that i couldnt work with it anymore.
    I got in touch with this east european based virus sellers helpdesk. I wanted to get rid of this virus program. The help i got consisted out of them trying to selling me more software.
    After that i visited all the forums from Apple. Found i am one of the thousands victems they made. Tried some of the solutions i found here.
    So i decided to reformat my hard disks and install all my programs again.
    But STILL, whereever i go i get pop-up for this malware program. Some SO bad that the only choice you have is eigther click on oke to install this rubish again OR you have to close safari to get rid of this virus attach!!
    I have been writing to Apple, who peddle this virus without any answer!! Safari, same thing
    And now i am fat up !!
    If Apple is in need of a couple of million more, no problem, they deserve it. But if, after EVERYTHING i have been reading here, still sell this malware/virus and dont CARE about their customers enough to so something about it, then it stops for me!!
    I am shure that the Apple delete police will take this edit away again, and i will get another B....T email that "according to our rules......." but then we will take this a couple of steps further! We are now, just started, 1290 victims of this zeobit, and we are building a website about their policy how to push this virus thrue everybodys troath, and the lack of reaction to this from Apple.
    And we will make SHURE that whenever someone in this world types in zeobit, mackeeper, clean your mac, we WILL be the number one hit in Google!!
    Because now they REALLY p...d us off !!
    PS...just to show how Apple thinks about their precious zeobit, i found out that any comnination of the words zeobit-mackeeper with words we use everyday, or in connection with organised crime is enough to refuse your edit.

    Consider that people here have been helping and telling people and some wrote up their own User Tips and that Apple has a tech note, a link at the top of this and other forums, on how to avoid, not installl, and remove this type of ransomware malware.

  • Clean your mac??

    I actually have a question. I get these "clean your mac" pop ups every now and again and I was wondering if they were legit or if it is some sort of virus?
    Thanks!!
    Amy

    Ignore them. What they are selling you don't need to spend your money on. All you really need to know you will find here:
    Kappy's Personal Suggestions for OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation.  TechTool Pro 4.5.1 or higher are Intel Mac compatible;  Drive Genius is similar to TechTool Pro in terms of the various repair services provided.  Versions 1.5.1 or later are Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
    I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.  Other utilities are also available such as Onyx, Lion Cache Cleaner, CockTail, for example.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that the Snow Leopard version will also work with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Backuplist
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    iBackup
    JaBack
    Silver Keeper
    MimMac
    Retrospect
    Super Flexible File Synchronizer
    SuperDuper!
    Synchronize Pro! X
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.

  • Should i install clean my mac?

    Is it wise to install Clean My Mac or a similar product on a MacBook Pro? Is it necessary? Is it useful? Is it harmful?

    I would like to concur with 71.
    In my testing of the so called "cleanup" apps, I find them to either be worthless or dangerous with a few like MacKeeper to be both worthless and dangerous at the same time.
    They are something to be avoided.
    The only thing they are good for is lining the vendors' pockets with gold.
