Q: 2010 Mac Pro upgrading to El Capitan
I have a mid-2010 Mac Pro (5,1) I was running Mt. Lion. But there is 2 applications where the new versions only work on 10.10 or higher, so I figured why not upgrade to El Cap?
And that's when all the problems started. I downloaded the El Cap installer from the App Store. I put it onto a USB drive, and installed it from there and after it was finished installing, and I got to the desktop, I restarted the machine, then I got the first picture (kernel panic?). Then it will reboot and then I get the second picture (mac gray screen of death) and it goes through this cycle of rebooting 2-4 times, before it finally reaches the desktop.
I thought that it was because it was done via the USB installer, so I tried again going from the recovery drive and erasing the partition. Still the same thing
Then I tried going directly from the OSX installer and still the same thing.
I updated to 10.11.1 from the Support website and still the same thing. In the El Cap environment, it's very sluggish and boot up is very slow, and this is installed on a 256GB SSD.
I installed it on my 2012 MBP also on an SSD and it runs fine.
My conclusion is that for some reason or another it does not like the hardware in my Mac Pro and it's causing what appears to be a kernel panic and this reboot cycle. Anyone else running a silver Mac Pro have this problem? For the moment, I have downgraded to OSX Yosemite and it seems to run fine.
OS X Mountain Lion (10.8.5), 256 SSD 2x2TB_raid 32G RAM GTX 680 3x23LCD
