This is a G5 2.5Ghz Quad. OS X 10.5.6. 8GB RAM. I get the boot sound, then a grey screen. That is all. Then the fans start blowing real loud until I turn it off.

Except where noted, the procedure for the Panasonic version is the same. This procedure requires a long-handled 2.5 mm hex wrench. Preliminary Steps.

Details: The 'Introduction Date' refers to the date this model was introduced via press release. Usually, the 'Discontinued Date' refers to the date a model was replaced by a subsequent system, but in this case Apple continued to sell the Power Macintosh G5 'Quad Core' (2.5) for roughly a month after the introduction of the Mac Pro on August 7, 2006. 661-3584, Logic Boad Power Mac G5 2.3 820-1592 630-6908 M9748LL A1047. The Power Macintosh G5 Dual Core (2.0) is powered by a single 'dual core' 2.0 GHz PowerPC 970MP (G5) processor with dual optimized AltiVec 'Velocity Engine' vector processing units (one per core), four double-precision FPUs (two per core), 1 MB of on-chip level 2 cache on each core, and a 1.0 GHz frontside system bus.

This is what I have tried:

  • replace with other RAM
  • unplug drives
  • Reset nvram like in this article. The problem is then that I have problems getting to OpenFirmware. Sometimes I am able to but when I get to the OF screen there is no reaction from typing. I can i.ex. type the first line but then there is no response from the keyboard. The keyboard is plugged directly into the USB port.

I got hold of the Apple Service Source Manual for Quad G5. (Let me know if someone needs that!) and just getting to the cooling and the power supply seems a bit tricky. So I read about this Apple power supply exchange (http://www.apple.com/support/powermac/po..) and am trying for that first. So it seems from the LED light that the CPUs are overheated and that could be related to the power supply going bad. I will post results of my shot at Apple.

  • UPDATE - THINK I MAY GIVE UP **

I took the machine to an Apple service center and they confirmed it was the processors gone bad. Of course this has to do with the cooling failed. Still I was not able to get a warranty repair even if I showed them the extended powersupply article and the article about the cooland leak. They said the machine was too old. They did offer me to fix the machine for about $1300. Since this is 2 machines with same error and since I have 16GB of RAM invested in each one just before this all happened, I might just have to accept the offer. Any comments?

Is this a good question?

Comments:

This is a great question. Letting us know what you've already tried makes it much easier to provide useful diagnosis.

Thanks for all advice. I tried to replace the clock battery, used the CUDA button, removed all but 1 RAM module. No luck. Now there is not even a grey screen. Strange because I have 2 G5s that are exactly the same and both are sick now in the same way.

I have a dual 2.5GHz G5 with the same problem. Has always been a problem with spotty booting for the past few years, but after a recent minor OS download/update and reboot, I got the gray screen problem. Took to the Apple Store and all tested out except the CPUs and MOBO. Not worth spending more than $200 to fix this thing (already have spent way too much time). Have never had so many issues after 20 years of Mac ownership as I have with the G5 line..

-UPDATE-

I really gave up on these. They look nice and shiny standing along the wall not doing anything. I bought a couple of new MacPros Intel. They are just speed demons compared to the G5s. I don't think Apple really tried to get away with a bad product, just turned out to be like that. I always have been impressed with Apple Support but this time I feel like the sucker spending tons of money on RAM upgrades that nobody wants or can use anymore.

This was a bad story for me and a lot of you guys with similar experiences, and of course for Apple. They did not make that many mistakes but they obviously should have stopped the G5 project a long time before it got out of hand. Guess it was like putting a Porsche motor in a Beetle. Sure it will speed but it will not last long.

So I admire you guys if you really want to find out hos to fix these but I suggest you accept you spent too much money and do like me and get yourself some new stable MacPros. They should pay you back what you lost and you will be happy once again and love Mac :-)

Just the following would work: difftool = kdiff3If you installed kdiff mounting the dmg file to kdiff.app then set your local path as following: difftool 'kdiff3'path = directorypathwhereyouinstalled/kdiff3.app/Contents/MacOS/kdiff3. Diff two files mac. In my current setup Mac OS 10.10.5 git diff tool is git merge tool that I want to replace with kdiff. In.gitconfig file I setup up the git diff as follows: difftool = kdiff3difftool 'kdiff3'path = pathdirectory/kdiff3.appIn this setting kdiff is not accessible and I get the following error when I run in terminal git difftoolThe diff tool kdiff3 is not available as 'Kdifflocalsoftwarepath/kdiff3.app'fatal: external diff died, stopping at modifiedfileDo you have any suggestion I can fix this issue? Kdiff3 is generally located at the following location: /Applications/kdiff3.app/Contents/MacOS/kdiff3so, try difftool 'kdiff3'path = /Applications/kdiff3.app/Contents/MacOS/kdiff3If you installed kdiff using brew, then you'd not need the difftool parameter in config for git 1.8 onwards. .
