Hello. I'm running OS X 10.5.8 on my iMac 2 GHz PowerPC G5 but since the most recent updates (due to iPhone 4S launch and associated updates to Mac systems to support it), my computer is running much slower. Any suggestions on how to fix this problem would be much appreciated. Thanks!

    Hello Misty, is that the ALS or the iSight model?

     

    Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.

     

    How much Ram do you have?

     

    So we know more about it...

     

    At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware> and report this upto but not including the Serial#...

     

    Hardware Overview:

     

    Model Name: eMac

    Model Identifier: PowerMac6,4

    Processor Name: PowerPC G4 (1.2)

    Processor Speed: 1.42 GHz

    Number Of CPUs: 1

    L2 Cache (per CPU): 512 KB

    Memory: 2 GB

    Bus Speed: 167 MHz

    Boot ROM Version: 4.9.2f1

    How much RAM?

  • BDAqua Level 10 Level 10 (114,755 points)

    Yes the ALS, (Ambient Light Sensor), model which can hold up to 2GB of DDR PC3200 RAM, (Memory), but only came with 512 MB & you didn't show Memory for some reason.

     

    I'd mazx out the RAM, it's easy to do yourself...

    1.5 GB will make a small difference at least, but may not be worth the cost. Open Console in Applications>Utilities, are any messages repeating as you work? Then open Activity Monitor, click on the System Memory tab, report the # of Page Outs.

     

    One free thing that may speed it a bit, I think you should get Applejack...

     

    http://www.macupdate.com/info.php/id/15667/applejack

     

    After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...

     

    applejack AUTO

     

    Then let it do all 6 of it's things.

     

    At least it'll eliminate some questions if it doesn't fix it.

     

    The 6 things it does are...

     

    Correct any Disk problems.

    Repair Permissions.

    Clear out Cache Files.

    Repair/check several plist files.

    Dump the VM files for a fresh start.

    Trash old Log files.

     

    First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)

     

    Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

    I may have spoken to you on other topics...this person has the same exact model I do.

    Model Name: iMac G5

    Identifier: PowerMac 8,2

    Processor Name: PowerPC G5 (3.0)

    Processor Speed: 2 GHz

    Number of CPUs: 1

    L2 Cache: 512 KB

    Bus Speed: 667 MHz

     

    Running OS 10.5.8 and the "software update" is up to date.

    But I have 500 GB HD but the graphics card is a ATI Radeon 9600 running at 128 MB

    And the video lags on everything online. Can I upgrade the video card or do I also have to change out the logic board too? Everything else works great, just internet streaming.

    If you could change the logic board, you could only change it to another PowerPC logic board.

    Streaming video from the Internet will always be a challenge and a struggle no matter the graphics engine.

    Better graphics cards may improve the chances of streaming the video content, but it will not be perfect.

    There maybe some frame dropping or some other issues where the video stream will be viewable but less than perfect.

    Many Modern Internet video codecs are simply not compatible with older Apple, PowerPC conputers and hardware.

    On some sites, if you can change the streaming protocol from say 720p to 480p, you maybe able to stream online content.

    Another thing is you might have success on watching certain types of online video if you are able to download the content directly to your PowerMac's hard drive first. You can try apps like VLC Player, Mplayer, the Flip4Mac plugin for Quicktime to view Windows Media Player files, there are various YuTube downloader apps for viewing that content.

    So, there workarounds for not being able to stream video content directly from a website.
