Optimizer for Mac OS 10.4.7

HI-
Does anyone make a disc optimizer for Mac OS 10.4.7? Can't seem to find one.
Thanks-
Dave Mitzelfeldt

Hello,
It's not usually necessary to defrag on the Mac. OS X has several routines built-in that minimize fragmentation.
You can read about those here:
http://docs.info.apple.com/article.html?artnum=25668
Because of the way OS X organizes it's files, you can actually slow-down your system by defragging it. OS X will place some files where it can access them more quickly. Defragging, will put those files where-ever the program determines suitable (it will treat them like any other file). So, the system may operate more slowly until OS X gets all those files put back where it likes them.
But if you want to defrag, here are two good programs:

I hope this helps.
Let us know if you have other questions.

  • A collection of FLV downloader, FLV player, and FLV converter for Mac

    A collection of FLV downloader, FLV player, and FLV converter for Mac
    Are you prepared to download FLV videos from YouTube, Google Video, metacafe, Yahoo! Video, Reuters.com, and many other video websites to play on your Mac or portable players, or do some further editing with certain editors? In my experience, assuming you have this idea, you must take advantage of three kinds of tools, including FLV downloader, FLV player, and FLV converter to achieve the goal.
    Of course, I am not speaking this to depress you, but to share my collections of these tools to show my kindness. Sure, just for people who have these needs.
    At first, I’ll introduce you several FLV downloaders for Mac, I have tried all of them, and basically they can achieve my goal of downloading FLV videos online.
    Free FLV downloaders for Mac:
    Web Video Downloader for Firefox
    Free Video Downloader for Mac
    Free YouTube Downloader for Mac
    I also know some free FLV players, and recommend them to you here, hope they can assist you to play FLV videos on your Mac smoothly.
    Free FLV player, Mac OS X:
    Adobe Media Player
    Wimpy FLV Player
    QuickTime, after installation of the Perian video plugin
    SWF & FLV Player
    CorePlayer
    (Tip: the above pieces of software can easily be searched in Google, so I do not give you the links here. I’m sure you can get them with ease.)
    Well, we have gone through the FLV downloaders and FLV players in the above passages, now it’s time to introduce you a FLV converter for Mac. This program I recommend is Pavtube FLV Converter for Mac, which can perfectly convert FLV videos to a wide range of video formats, so that you can do whatever you like with the resulted videos, such as playing on your iPod, iPhone, BlackBerry, PSP, Apple TV, etc. or exporting to iMovie, Final Cut Pro and Final Cut Express to do further editing, or doing something else as you like. But how to use it? You may ask me. Take it easy, a step-by-step instruction is involved in the following part.
    1. Download, install and run this program
    A sky-blue interface will be shown to you as follow:
    2. Add files, set output format and destination folder
    Input FLV files to it by clicking button “Add”, and select a format as the output format in the drop-down list of “Format”, meanwhile, you can press “Browse” to specify the destination folder or just use the path set by default.
    3. Set advanced settings
    Click button[b] “Settings”, the following interface will pop up. You can change the parameters like screen size, bit rate, frame rate, sample rate, etc. to optimize the output videos.
    4. Convert
    This FLV Converter for mac can definitely complete the conversion at a swift speed with excellent quality, also it do not have the problem of audio-video out of sync. Therefore you need not worry about these issues. Moreover, if you want to add watermark as your own logo or reserve your copyright, you can totally do it with this program.
    Ok, the introduction to the three kinds of tools which you may need while dealing with FLV videos is over, sincerely hope they can deliver you useful information, because you know, it’s my original intention.

    Hi Greg,
    So if I understand correctly, your findings are:
    Flash Player 10.1.85.3 + Flash Media Interactive Server = Jerky Video
    Flash Player 10.0.x.x + Flash Media Interactive Server = Smooth Video
    Flash Player 10.1.85.3 + Wowza = Smooth Video
    And what about Flash Player 10.0.x.x + Wowza?
    Also, if you could check the network traffic to confirm if it's Flash Player causing the issue or it is receiving it like that from FMIS.
    Cheers

  • Send attachments from finder via Outlook 2011 for Mac

    I am trying to right click attachments in finder and choose send by mail. Unfortunately only mac mail comes up and I need to use outlook 2011. Its installed and chosen as default in both outlook settings and mail settings.
    Can drag attachments to outlook icon but would be easy to have right click option.
    Auto optimize size of attachments like outlook for windows did would also be helpful for large file sizes.

    I believe this article should resolve this problem for you:
    Create a Service to attach files to a new Outlook for Mac mail message
    Also, you should be able to drag/drop a file from the Finder onto the Outlook icon on the Dock.

    To learn how to defend yourself from the threat of adware read How to install adware.
    There will always be threats to your information security associated with using any Internet - connected communications tool:
    You can mitigate those threats by following commonsense practices
    Delegating that responsibility to software is an ineffective defense
    Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
    OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "clean up", "speed up",  "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
    Illegally obtained software is almost certain to contain malware.
    "Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
    If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
    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 iCloud, 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.
    Java can be disabled in System Preferences.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
    Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
    The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver movies or other copyrighted content "for free".
    The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget 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. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
    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.

  • Is there Java 6 for Mac as well?

    I am not so sure if i m asking this in the right place.
    is there a section dedicated for java 6?
    but i really like to know, if there's Java 6 beta for Mac as well.
    thanks.

    AFAIK Apple usually takes the JDK/JRE from Sun and modifies it to run on Mac OS X afterwards (and usually they add some optimization as well). That's the reason why JDKs for Mac usually are a bit behind and probably the reason why there's no beta of Java 6 yet.

  • Conflict with Kaspersky Internet Security 2014 for MAC

    I installed Kaspersky Internet Security 2014 for MAC.
    Its Web anti-virus function does not work well. After enable for a while, it blocks all internet connection.
    I tried many ways, included
    - putting Safari, Itune, ...into KIS's Trust Zone application
    - set Pravacy for KIS control OS X
    but it seems no effect.
    Is there someone getting the same issue with me?
    Any solution?
    Thanks.

    Despite repeated attempts I was unable to install Kaspersky's latest software on a new copy of Mavericks shortly after its release.
    Its installer failed:
    Kaspersky's product may have been updated in the last couple of weeks, but given that developers have had many months to prepare for Mavericks, it calls their competence into question. It's your Mac, install what you want, but the number of problems reported on this site that are directly attributable to using such junk exceed those caused by actual malware by orders of magnitude.
    Protect yourself by observing these few basic principles, not by delegating that responsibility to Kaspersky or anything like it:
    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.

  • No photo stream on Photos for Mac?

    I upgraded to Photos for Mac and loving the new look. I also have the latest iPad and the iPhone 6 both running iOS 8.3. I loved the photo stream feature when all my photos, or at least the most current, would appear automatically on my 2 other devices. Its still happening for my iPad but not anymore on Photos for Mac. Photo stream option is enabled on all my devices' iCloud settings and on Photos for Mac preferences so not sure what am missing?

    HI,
    Maybe try it this way this is what I did with mine because I did not migrate and didn't know about that either.
    and really have the sidebar so because it will help you get the pictures organized
    Photos application for Mac Instructions that might help!
    On your iPad,iPhone keep the iCloud on in settings for Photos.
    if you have not opened the New Photos application yet to have it transfer your photos from iPhoto let it Transfer the Pictures.
    once you have all the pictures from iPhoto to Photos then in Photos go to Preferences
    there is general and iCloud tab and go to the iCloud and only uncheck the iCloud button that will make it so it doesn't sync with your iPhone and iPad for Photos.
    Then in Photos go up to View and press show sidebar because with that view you can move your pictures easier to albums snd delete or move any pictures or make new albums
    For Duplicates if you have a big pile in a row and I mean not like every other picture of the same pictures on the keyboard Hold down the shift button. or the other way is to Hold down the Command buttom that is right by the space bar then on the trackpad or mouse click once on the picture you want to delete and do a bunch at a time then on the last picture of that pile either right click the picture and delete or go up to the edit button which is next to file on the top left and click delete in edit. 
    when you are all done with moving around your pictures or whatever go back to Preferences and turn on iCloud and make sure you have the optimize Mac Storage and then you are done! I hope this makes sense and works for you! here are the 2 pictures I'm talking about in settings.

  • Zend Optimizer and Mac OS X 10.5 Server

    I'm looking to install Zend Optimizer on Mac OS X 10.5.8 Server but it's seems
    that the latest version of Zend Optimizer is not compatible with the 64-bit version
    of Apache. Anybody with a solution?

    Unfortunately Zend will not be made for Mac OS 10.5 in a 64 bit version. The company has decided not to develop a version for Mac 10.5 64 bit. They have an alternative free product but it is similar to installing MAMP Pro and changes all your PHP, MySQL, and other dependencies It is a sad day.

  • Quick way to change "Optimize for" setting when "mirror displays" is on?

    Is there a quick way to change "Optimize for" setting when "mirror displays" is on?
    I have two displays on my Mac Mini for totally different areas; I can't see the first monitor when I'm on the second. One is 1280x1024, one is 1920x1200. As I switch fairly often I'm wondering if there is a built-in or 3rd-party-utility way to quickly toggle the "optimize for" setting that is under "System Preferences" -> "Displays" -> "Display" tab -> "Optimize for:" dropdown box.
    As Apple sadly doesn't make a all-in-one keyboard / mouse - need one as one of the monitors is used for just a very comfy chair, so keyboard is on my lap - I'm using an Lenovo ThinkPad USB Travel Keyboard, model SK-8855, and some key cobinations, esp. with function keys, seem not to work on it. So something from the desktop context menu or that allows you to set the hotkey would be preferable.
    Thanks for any help,
    -DJBC

    I'm thinking that, Display Menu from the Mac App Store will help.

  • WHAT REPAIR UTILITY CAN I USE BESIDES NORTON UTILITIES FOR MAC 0S 10.3.9?

    I have been reading about the Disk Utility and repairing "repair permissions" and frankly I am confused. Since we cannot ue Norton Utilities for Mac OS 10.3.9. Is there a repair utility which will "deep fix" my hard drive the way that Norton used to before Panther? Some say Disk Warrior and some say Tech Tool. Which one is most effective or is there something else for Mac? Thanks.

    Marcia:
    In addition to Disk Warrior, mentioned in an earlier post, there is also Tech Tool Pro. DW does a great job of Directory repair and rebuilding. TTP repairs and rebuilds the directory in addition to hardware check, disk scan, files check, and files and disk optimization/defragmentation.
    The first recourse, should always be, of course, OS X's own built in Disk Utility (Applications/Utilities/Disk Utility), for Repairing Disk Permissions and Repairing the Disk, along with other tasks.
    ali b's links to maintenance sites also link resources for Unix Maintenance (also referred to as CRON cleaning) a very important maintenace item, and other very helpful utilities.
    Sorry if this sounds a bit confusing. The sites ali linked have a lot of very useful information and I recommend that you check them out. May I, in addition, commend you for discontinuing the use of Norton.
    Good luck.

  • When using office for mac or i studio after inserting several pictures, my computer locks up and the only way I can fix it is to do a force quit.  Why does it do this and how I I get it fixed without a force quit?

    I have a mac book, with office for mac and iStudio installed.  When I try to create a document using either one of these; after inserting several photos, the computer locks up and the only way I can get it to unlock is to do a force quit.  Why does it do this, and how can I get it to unlock without having to do a force quit?

    Are you using versions of the software that are compatible with the version of OS X you have installed? Very often such lockups are caused by application incompatibility.
    The problem may also come from trying to use both sets of applications at the same time while not having enough RAM installed. Adding more RAM may fix the problem.
    The problem can arise from corrupted support files such as preference files or Application Support files or corrupted cache files.
    The image files you are using may also be corrupt thus causing the problem.
    You might start with:
    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 log files 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 this version also works 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

  • What is the best Maintenance Software for Mac?

    I am looking for the best maintenance software out there for mac, anything similar to clean my mac..etc, etc,
    What do any of you recommend. Price is not an issue.

    1. Disk Warrior - fixes many problems Disk Utility can't even find. The most common potentially
    serious problem Disk Warrior fixes that Disk Utility won't fix are Directory Structure problems.
    2. iDefrag - a disk optimizer.
    Why Defragment?
    It has often been asserted that defragmentation (or disk optimization) is not a good idea on
    systems using Apple’s HFS+ filesystem. The main reasons given for this historically have been:
    HFS+ is very much better at keeping files defragmented than many other commodity filesystems.
    Advanced features in recent versions of HFS+ can easily be disrupted by a defragmentation tool
    that does not support them, resulting in decreased performance.
    There is a risk associated with defragmentation.
    Whilst these arguments are certainly valid, they are not the whole story. For one thing, iDefrag,
    unlike most other disk defragmentation tools, fully supports the most recent features of HFS+,
    namely the metadata zone (or “hot band”) and the adaptive hot file clustering support added in
    Mac OS X 10.3. Not only does it avoid disrupting them, but it is capable of fixing disruption caused
    by other software by moving files into or out of the metadata zone as appropriate.
    Sensible arguments for occasional optimization of your disk include:
    HFS+ is not very good at keeping free space contiguous, which can, in turn, lead to large files
    becoming very fragmented, and can also cause problems for the virtual memory subsystem on Mac
    OS X.
    Older versions of the Mac OS are not themselves aware of the metadata zone policy, and may
    disrupt its performance.
    HFS+ uses B-Tree index files to hold information about the filesystem. If a large number of files
    are placed on a disk, the filesystem may have to enlarge these B-Tree structures; however, there is
    no built-in mechanism to shrink them again once the files are deleted, so the space taken up by
    these files has been lost.
    Whilst HFS+ is good at keeping individual files defragmented, mechanisms like Software Update
    may result in files that are components of the same piece of software being scattered across the
    disk, leading to increased start-up times, both for Mac OS X itself and for applications software.
    This is a form of fragmentation that is typically overlooked.
    Defragmenting disk images can be helpful, particularly if they are to be placed onto a CD/DVD, as
    seeks on CD/DVD discs are particularly expensive.
    Some specific usage patterns may cause fragmentation despite the features of HFS+ that are
    designed to avoid it.
    We do not recommend very frequent optimization of your disk; optimizing a disk can take a
    substantial amount of time, particularly with larger disks, far outweighing the benefits that are
    likely to be obtained by (say) a weekly optimization regime.
    Optimization may make more sense, however, following large software updates, or on an
    occasional basis if you notice decreased performance and lots of hard disk seeking on system
    start-up or when starting an application.
    3. Snow Leopard Cache Cleaner.
    - Lots of goodies in that one.
    4. Clix - literally, hundreds of utility scripts.
