    I have an iMac g4 800mhz, 768 mb of ram 40 gb internal HD and 250 gb external HD. I plan on upgrading to Tiger this wednesday. Also, my mac has been a bit quirky over the last year or so. The internal HD seems to almost spin constantly. It spins and spins....spins down, then right back up again. Weird. Once in a while the apps act strange as well. So, I plan on doing a clean install of Tiger. Everything is backed up on the external HD.

    My question is, does anybody know how Tiger will run on my system? Will doing a clean install eliminate these "quirks"? And finally, will quicktime 7 finally run smooth with the upgrade? Right now, Quicktime isn't as smooth as it used to be with Quicktime 6.

    Thanks for your help people!
    And thank YOU Apple for eliminating firewire so that the case could be 1/32 of an inch smaller and now my iPod transfers take hours!

    I don't know if the upgrade will fix your problems but Tiger will run fine on your Imac. I put it on my sister's (was mine till I upgraded to a G5). The only difference is her's has 1 gig of memory and I upgraded the hard drive to a 120 gig.

    From my experience with an iBook G4/800, I think it'll be okay too...

    I found two things:

    1) Tiger seems to suck up a little bit of ram, practically speaking, so that many applications run slightly more slowly and VM use creeps up more quickly in Tiger than Panther. I have 640 MB and it feels like, if I had about 128 MB more or so, things would be back to the way they were in Panther....

    2) Tiger is much pickier than Panther, as numerous threads discuss, about free HD space, especially on the main drive. Try to situate yourself so you have 8-10GB free on that main boot drive.

    I think if you take those two things into account, it will be a nice experience. Spotlight has become a very regular part of my usage profile.... :)

    tiger will run great on that system. zero the drive first and then do a clean install. doing a zero on the drive first should make it work like a new drive.

    if you still have issues with the drive always spinning then go to energy saver in the control panel and check "Put hard disk to sleep when possible"

    Tiger will run fine on that system, but I'd be a bit worried about the health of your hard drive. A clean install won't make any difference. Do it because you want to, not because you need to.

    So if this won't fix any of my problems, erratic HD spinning, unexpected quits, quicktime jerky. What will? I figured starting over at "zero" should bring things back to their original state. I have "put HD to sleep when possible" checked. No help. I'm sure I have alot of junk files in random spots around the finder from junk "free" applications. I think these might be causing erratic behavior. Could be wrong though, I'm no expert.

    Thanks for your help everybody

    all I can think of that could be causing all of that HD activity is that it must be a lot of VM activity.

    Mac OS X TIger

    Mac OS X tiger should run perfect on an iMac G4. The iMac G3 runs it perfectly.

    hope it helps,

    Reviving a five year old thread isn't always a good idea. Especially if you're doing it just to up your post count.
