Hi,

 

Older than dirt mini running 10.5.8 with the following specs:

 

Model Name:Mac mini
  Model Identifier:PowerMac10,2
  Processor Name:PowerPC G4 (1.2)
  Processor Speed:1.5 GHz
  Number Of CPUs:1
  L2 Cache (per CPU):512 KB
  Memory:512 MB
  Bus Speed:167 MHz
  Boot ROM Version:4.9.4f1

 

Gravy thick slow.  Is there anything I can do to improve it?  Thought about reinstalling but don't have the media after a move and carelessness.  Mostly just want this to be dependable kid box, don't need anything fancy.

 

Thanks for any suggestions.


Mac mini, Mac OS X (10.5.8)

    Hello, upping it to 1 GB of RAM will help...

     

    http://eshop.macsales.com/item/Other%20World%20Computing/5300DDR2S1GB/

     

    Keeping 30 GB of free space on the Hard Drive will help.

     

    Keeping icons on the Desktop to a minimum will help.

     

    And maybe cleaning up Caches & such...

     

    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.

     

    Just sits there occupying very little space & never interfering, unless you need to invoke it in Single User Mode.

    I have exactly the same mac mini as this!  A G4 "silent upgrade" with the 1.5GHz processor.  Quite rare these machines are.

     

    yes, they are slow.  I agree - you need to upgrade the memory to the 1GB maximum.  Doesn't sound like much, but as this is a powerpc processor its different to an intel processor and you will get benefit from this.

     

    If it still has the same hard drive it shipped with, you should replace this with something like a western digital scorpio blue 360gb.  Its an IDE/ATA drive, its NOT SATA!

     

    You will need the apple service source manual (or similar) to perform a hard drive replacement yourself (its not easy, and requires time and care).  The shipping hard drive was slow, and this will be a big improvement.

     

    The clock speed of the processor is controlled by solder points on the logic board.  Some people have tried "over clocking" the macmini, with varying results (I suggest you don't try this, but google search and you can read about it).  I think you can potentially clock it to something like 1.67 GHz

     

    A re-install of Mac OS X will also help, if you can get a copy of Leopard.

    Hi.

     

    At this site not finding memory for my model.  Am I looking in the wrong place?

     

    http://eshop.macsales.com/item/Other%20World%20Computing/5300DDR2S1GB/

     

     

    Will that one work, even though model not listed?  (Have never opened up this mac).

     

    Thanks!

    See this: http://eshop.macsales.com/shop/item/6559/OWC2700DDR1024/

     

    or from Crucial, see http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=AC5AFF5DA5CA7304

     

    I used the Crucial memory in my G4 1.5Ghz mini, which has worked fine. Crucial has free shipping, and you can usually find a 5% off on retailmenot.com . The OWC memory should work fine too.

    OOPs... YIKES, apologies, I posted the wrong link, but BGreg has provided the correct link for the proper RAM.

     

    Thanks BGreg.

    I was running a  1.6 GHz G5 with 3GB of memory and tons of free HD space. It was getting rather slow. You can pick up a 2.4GHz intel iMac (used) for roughly $500. That's what I did, because other than going back to 10.4 or 10.3, speed was not an option. I've not even tried 10.5 an a G4 processor even though I have a few dozen at work that I could try it with.

     

    While I agree with everything suggested I think you may be hard-pressed to get appreciable speed increases on an old G4. Remember, it's not just the OS that is taxing your G4's capabilities, but newer apps are also written for faster machines.

     

    You may just be spitting into the wind,

     

    On the other hand, I don't blame you for trying to squeeze all the life you can out of your old Mac.

    I think my G4 Cube has a 1.2Ghz G4 in it (I upgraded it), max memory I think at 1.5GB, and it runs 10.5 fine.  But similar to what jrbw3mi wants, it's light duty machine: a bit of browsing, email, word processing, and the like. It's days of doing heavy work are over.

     

    I also have an MDD G4 1.0GHz dual (CPU daughter card from an XServe, the original 867 dual lost a CPU) running 10.5. Works fine as an, albiet loud, file server. I've been thinking of retiring and donating that one, I already have another MDD G4 1.25 dual running 10.4. I need/want to keep one last OS 9 booting machine around, having two is a bit much. They're loud as heck, and the MDD G4 1.25, which was seeing light duty anyway, is getting replaced by a Mini Server -- getting there because I'm still figuring out Lion Server.
