Hello everyone,


I'm new to this forum, I'm really searching for some help with my "project" and hope some of you can help me out with this one!


It's all coming down to a not starting "Finder"



The full story,


I bought a Mac Pro 1.1 (2006) a few day's ago. All stock, dual Intel Xeon 3Ghz, 5GB Ram and the stock video card (256MB). (Lion freshley installed)


I wanted to upgrade to OSX El Capitain, and after a lot of research and a lot... yes a lot of trouble in making it all work I finally got it. I've thrown in a Geforce GTX 760 2GB Jetstream... couldn't wait to get cables for powering it, so I frankensteind it all with a second PSU. Installed Lion on a Samsung 850 EVO, and then followd a tutorial on how to install el capitain using Piker's boot. 


After 12 hours non stop messin around it worked, only after some time the mac froze and rebooted. I noticed that maby Google Chrome caused this to happen, and when using Safari it would work without any problem. I even can play 4K flawless.

But still after some time it would crash, I monitored the CPU and Ram Usage, but there wasn't anything crazy happening at those things.


.. didn't really got the time to instal other apps. Then I found out Finder wasn't responding. It kept on crashing. I tried a lot of things... deleting the plist files, resetting PRAM, VRAM, Savebooting, deleting cache, Disk repair (Disk Aid)... nothing worked.


Is this maby a problem with the bootloader (Pike)?


I hope someone can help me out!


Thanks in advance,

Greetings from Holland

It sounds more like bad RAM to me.

Pull out the RAM. Install a pair at a time to see if you have a crash. Remove one replace; repeat.  Its tedious as you you are trying to find out which stick or sticks are bad. You have to be methodical.
