Tiger install screwed a Powermac G5

**groovy_stu** · May 10th, 2005, 12:06 PM

OK guys, I have a PM G5 1.8 dual with 4.5 GB Ram.

Under OSX panther, it worked fine no probs. So decided to give Tiger a go. Thinking only 30 minutes and everything will be wonderful and my G5 will have a new spring in its step!

As ever, a clean install was the case with everything backed up and safe, so I haven't lost anything. The only trouble is, when Tiger eventually got on my G5 as the installer kept crashing (this took 4 hours to eventually work); Tiger ended up being so unstable I could only use it for about 5 minutes, the G5 would then simply freeze.

I have done loads, called Apple who when through everything from taking out the ram, and other bits, to resetting the PMU and so on. Still no joy. It was then taken to an Apple Centre who really didn't do a great deal. They ran hardware test's and said it was fine, and re-installed tiger. They said that it was running fine for hours without a hitch, what they actually failed to do was actually use the G5 with Tiger and see how stable it is.

Now, I decided to leave tiger alone and erase and zero the drive and go back to Panther. However, the panther installer now does the same as the the Tiger installer did. Now I am dead in the water. All the G5 does is crash and I have to hard reset.

Ideally I'd love to have Tiger working properly, but then I can't get the CD out of the drive as the installer wont let me. But then Tiger causes the same crashing problem. Panther or any OS would be nice at the moment, but all that happens is the system will crash during instal.

Any ideas anyone?

Definitely sounds like a hardware issue to me. I haven't seen crashes during OS install on any Mac for some time now. Actually, I've never seen one crash during OS install.

If you try again installing Tiger (btw., you can force the mac to eject the disk at startup by just holding down the mouse button), keep the log window open at all times and look for any errors... I guess there's always _some_ messages in there, but maybe you catch something interesting...?

Hi Fryke

I've had my suspitions that it maybe hardware related. However, the apple centre did say that they did full diagnostics and everything came up trumps!

Will try what you said, however, how do I get the log window up and open when installing? So, perhaps I can isolate the issue!

Cheers, appreciated.

It should be in some of the menus... Just find and select it, it opens below the installer's window.

dodgy memory?

If some of your 4.5GB of RAM isn't Apple RAM it may be conflicting.

Well, I just fresh installed an iBook 1.2 ghz w/ 768mb of ram with Tiger. 512 of the Ram is NOT apple ram, its corsair memory.

Its not a big deal for me...but I would think that if you tried to install without all but apple ram, that might work.

BTW...Tiger is definately cool.. Not noticing any bugs for me yet. I'll call em as I sees em.

It is the extra RAM. First, start the Mac up with the mouse button held down. This will get the Mac to spit the DVD out. Them remove all the extra RAM you put into the Mac. Then use the Tiger DVD by holding down the "c" button during startup. Nuke and pave the Drive before the install. Then do the install. Hopefully this will work.
