What is Apple's position on system maintenance and optimization?

I mean, obviously something has to be done to keep our macs as fast as after an ex-novo installation...
apple engineers, please answer!

there is not a single issue, it's just a gradual decrease of the overall performance.
to give some examples:
- time to boot
- time to open safari, mail, itunes,... (actually aperture is still pretty fast)
- time to get the size of big folders
they are all related to the hard drive (i've got a 7200 rpm hard drive anyway). when the tasks are processor demanding, my mac goes as smoothly as always.
also, when i fresh install the system (i last did it when updating to SL) initially it goes fast and then, gradually, data access slows down.
i believe i'm not the only one with this kind of problem and it would be nice to have a way to fix it (other than re-installing ex-novo the os).

What is Apple's position on iOS4 ipod Touch problems?

Considering all the posts regarding battery drains, sync problems, crashes, and slow operation since the iOS4 release for the ipod Touch 3g it is time for Apple to provide an updated iOS4 and/or fix the problems.
Has anyone seen or heard of any information from Apple?

Any official information from Apple will almost certainly come in the form of a KnowledgeBase article, which would probably be referenced from the iPod touch support page, or in the form of an actual OS update.

System maintenance and clean up

From all the reading I have done, the way I understand the Mac is you should not have to do any system maintenance or clean up.
I was doing a spotlight search and several times tons of Entourage emails would show up. When I first got the Mac I gave Entourage a try before realizing I liked Outlook much better... so I deleted my exchange information from Entourage and discontinued using it.
I finally got curious as to why all these email files were showing up even though they had been removed from Entourage. I went traced down the folder and there was thousands of these Entourage email files in the cache folder!!
I deleted them all manually as they were taking a lot of space up.
What steps should I take to get rid of files like this, that the Mac obviously doesn't do automatically, so that I don't end up with Gigs of space being wasted in the long term??

I recommend first off, migrating away from Entourage*:

What's the difference between wcc system components and standard components

hi Experts,
My customer has a question on the difference between wcc system components and standard components, I didn't find it from doc, anyone can help on answering this?
Best regards

Hi ,
System components are those which are providing the basic functionalities on UCM server by default . Standard components are those which are provided as-in on the server but need to be enabled per case basis . For example Framework Folders which is not necessary for the basic functionalities but is needed if user wants to .
This guide gives the administration level overview for UCM : http://docs.oracle.com/cd/E23943_01/doc.1111/e10792/toc.htm
Hope this helps .

What is Apple's position on Anti-virus software for the mac?

I have started replacing my customers PCs with iMac's and Mac-Mini, and I have always operated on the assumption that anti-virus software is not necessary, but I fear that my opinion might need revisiting. So I would pose the question again, does the community and/or Apple have an opinion on the need for Anti-Virus, Malware and all the other nasty inflictions. If you, as a group or individually do recommend, what product would you recommend? Thank You --- Bill Shaw - Kansas City, Mo.

This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an attacker who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware. Starting with OS X 10.7.5, there is another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications that are downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Applications certified in this way haven't actually been tested by Apple (unless they come from the Mac App Store), but you can be sure that they haven't been modified by anyone other than the developer, and his identity is known, so he could be held responsible if he knowingly released malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. Note, however, that there are some caveats concerning Gatekeeper:
It doesn't apply to software that comes packaged as an installer. Treat all third-party installers with caution.
It can be disabled or overridden by the user.
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to applications downloaded from the network. Software installed from a CD or other media is not checked.
For more information about Gatekeeper, see this Apple Support article. Notwithstanding the above, the most effective defense against malware attacks is your own intelligence. All known malware on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. [Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.]
“Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Java on the network (not to be confused with JavaScript, to which it's not related) is always a potential weak spot in the security of any operating system. If a Java web plugin is not installed, don't install it unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the filesystem. Malware gets into the system by being downloaded, not by materializing from nowhere.
In order to meet that nonexistent threat, the software duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability and poor performance.
By modifying the system at a low level, the software itself may create vulnerabilities that could be exploited by malware attackers.
ClamXav doesn't have these drawbacks.

System maintenance and start up

Hello: Thanks in advance. My system works fine 90 percent of the time. I use DVD Studio Pro, FCP, Compressor, lots of DV media, 2 External Firewire drives, etc. Maxed out on Ram and Drive Space. Nothing too crazy.
If I ever have to restart my system, sometimes it takes 20 times for me to restart before it's good to go. Sometimes on the first restart it works fine. Other times it takes 10 times and I have to manually shut down and start up each time.
How can I fix this? What haven't I done? I have used Disk Utility, Mac Janitor, etc. to try and fix. Like I said. the system works fine 90 percent of the time. Thanks.
Craig

I think you may have some serious disk repair to handle. First, try the following:
Boot from your Tiger DVD. After the installer loads select your language and click on the Continue button, then select Disk Utility from the Utilities menu. After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
I would then download TinkerTool System and use it to clear out all user/system caches, font caches, etc. Navigate to the /System/Library/ folder and delete the Extensions.kextcache and Extensions.mkext files.
Then do a restart to allow the OS to rebuild the caches. If problems persist with applications crashing, then try creating a new user account and logging into that account. If the crashes cease, then there may be some corrupted preference files associated with the apps that are crashing.

*real* system requirements - and optimization ??

Greetings -
I have an aging Athlon XP 2700 CPU with 2GB of DDR333 RAM and a couple of SATA 1.5 Gb drives.
Will that really be adequate for Lightroom?
(I'll typically be working with ~10-15MB Pentax RAW files.)
Can the setup be optimized?
(e.g. - OS & application on one drive, photos on the other.)
Or should I not bother unless I upgrade my system?
Thanks kindly.

Programmed system maintenance

I read that OSX has pre-programmed system maintenance and there is discussion on whether the computer should be turned off at night.
Is there someplace I can check or reset my system maintenance?

To check when your Periodic Maintenance Scripts, which I hope is what you want to know, open Terminal and type this exactly:
ls -al /var/log/*.out
Press Return
and you should see three lines of info, one for each script: Daily, Weekly & Monthly. The date and time they were last run is in each line.
To manually run the scripts open Terminal and type:
sudo periodic daily weekly monthly
Press return. You will be prompted for your Admin password and you need to type this into Terminal. Be warned, it might take a long time to run the scripts.

Difference between system copy and Remote Client copy?

Hi,
Can any body suggest me , What are the major difference between System copy and Remote Client Copy.
As per my knowledge , Both are different
1.In system copy entire data recovered mean copy from Source to target
2.In Remote client copy All Client data can't me import if you choose SAP_ALL profile also
I hope Transaction data and user data can't copied
Anybody share this Question and Give me some idea about this
If anybody give brief explanation that is very gratefull.
regards,
Balaram

Hi,
System copy will replicate all database from source to target system.
In remote copy only client in which you are performing the copy will get refresh. Also, remote client copy will be done between systems on same patch level. with SAP_ALL profile you can bring all data in target system including your transactional data.
Thanks

When i go to System Preferences and click on Desktop and Screensaver the computer goes to that screen but gets stuck and does not respond no matter how many times i try. Any suggestions?

When i go to System Preferences and choose Desktop & Screensaver the system locks up and will not show any options. All i get is the circle of color and have to do a force quit. Any suggestions?

First follow the instructions in this support article.
If an iPhoto or Aperture library is the source of your desktop pictures, it may need to be rebuilt, or you may need to update the application to the latest version.
Otherwise, continue as below.
Back up all data.
In the Finder, hold down the option key and select
Go ▹ Library
from the menu bar. From the Library folder, delete the following item, if it exists:
Caches/com.apple.systempreferences
and move the following items to the Desktop, if they exist:
Application Support/Dock/desktoppicture.db
Preferences/com.apple.desktop.plist
Launch System Preferences and test. If you still have the issue, put the items you moved to the Desktop back where they came from and post again. Otherwise, delete the items.

What is the best system maintenance software to use for a MBP??

Hello everyone, I was formerly using Mac Tune-up for my Macbook Pro and it did an okay job but I am not sure what Mac software I should be using to keep my system clean while keeping it running at optimal performance. Turns-out I can no longer use Mac Tune-Up since I upgraded to Mavericks from Snow Leopard. Can anyone recommend to me the best system maintenance software to use for my MBP with Mavericks OS and where I can get it (a link or site URL)? Thanks in advance!

How to maintain a Mac
1. Make two or more backups of all your files, keeping at least one off site at all times in case of disaster. One backup is not enough to be safe. Don’t back up your backups; all should be made directly from the original data. 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 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. Before installing any Apple update, you must check that all such modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of trouble with system updates.
3. 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" and “MacKeeper” scams, but there are many others.
As a rule, the only software you should install is that which directly enables you to do the things you use a computer for, and doesn't change the way other software works.
Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. 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.
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.
4. 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.
5. 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 malware is 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 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.
6. Don't fill up your disk/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.
7. 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 maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform. A well-made 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, use a PC.
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.

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 4.0 is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.2 is Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. The current version, 1.5.1, is 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.
OS X automatically defrags 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.
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.
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):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

Bought iworks family via download. Apple told me to copy onto usb and then i could transfer to other family members. However, when gragged off usb onto desktop it will not work. Checked system requirments and everything fine. anyone know what the problem

Hi. Bought iwork family as a download rather than on DVD. Want to transfer to other macs in household. Apple told me to transfer to USB stick and then put on other macs. Doesn't work and get message saying "keynote cannot be opened due to a problem". Same problem for .pages and .numbers. I have reinstallled but same problem. Have checked system requirements and everything seems fine.Any one have any ideas how to solve this. Thanks

I'm an applications developer and also run a part-time videography business. As such, I require more than 3.12GB of RAM. That is the physical limitation of a 32bit system. Pointless to stay on 32bit if you plan on having more than that much RAM.
I'm also not about to pay someone to fix my PC when I can do it myself. I was originally hoping for someone who had experienced the problem before to point me in the right direction so I didn't have to spend so much time trying to figure out what the issue was for myself.
Basically, in the end the problem was caused because right at the point in time when I chose to uninstall, and reinstall; Apple released a new version of iTunes. This version in turn had a requirement of iOS 4.2 to sync with the iPhone. This is a pretty embarrassing for Apple that they would release software reliant on other software before said software was released.
Had I realised I was downloading a newer version at the initial point of installation, this wouldn't have been an issue. I could've easily have rolled back iTunes to the previous version and gotten on with my life.
Another issue is that iTunes is not actually a 64 bit application. It masquerades as one to allow installation on the 64 bit platform.

I am trying to update I-tunes, but I get the following error message. Service Apple Mobile Device failed to start and wants me to verify I have sufficient priveledges to start system services. I do not know what to do.

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Hi,
I had the same problem after upgrading to Yosemite. Illustrator CS6 wouldn't open. I got a message saying I should 'install legacy Java SE6 runtime'.
The link didn't work - it lead to a blank page.
So I downloaded Java8 (latest version) from Oracle but didn't install it. Something told me this was not the right way to go (the problem was with Java SE6, not 8). I then called Apple (in the Netherlands, were I live) for help. I got none. The best they could do was blaming Adobe for the problem or me, for not having the latest Adobe CC app. Rubbish.
And then, magic. I tried to open Illustrator again, got the pop up message but this time the link worked. It took me to an official Apple page, with a link to download Java for OS X 2014-001. The problem is now solved.
If curious, this is the explanation Apple gives for the problem:
'Java for OS X 2014-001 includes installation improvements, and supersedes all previous versions of Java for OS X. This package installs the same version of Java 6 included in Java for OS X 2013-005. On systems that have not already installed Java for OS X 2012-006 or later, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled 'missing plug-in' to download the latest version of the Java applet plug-in from Oracle.'
See http://support.apple.com/kb/HT6133 for more details about this update.

What is Apple's position on system maintenance and optimization?
