I have a 2009 Mac Pro that I retired about four years ago when I got my 2013 Mac Pro, but recently I upgraded the 2013 Mac Pro to 12 cores and I figured it's perfect upgrade for the 2009 Mac Pro.
Basically before I put the 2009 Mac Pro computer into storage (in the original box), the computer was working fine. I took it out the other day from storage and I removed all the extraneous drives only using a boot SSD (in a PCIe adapter) and a 2TB HDD in tray number 4.
It's running Mac OS 10.9 (Mavericks) and I can boot into Windows just fine. When i boot into Mac OS, where the login screen should be, I get a black screen. I've reset SMC, NVRAM, rearranged drives, etc., nothing seems to be working.
I don't have the original Radeon 4870 that came with this particular Mac because I sold that a long time ago. The current graphics card is the Sapphire Radeon 7950 Mac Edition. The only other graphics card I have is the Sapphire RX 580 that I use with my MacBook Pro eGPU setup.
The only thing I recall I did was I upgraded the Mac to 5,1 I think I originally planned to do this upgrade to dual 6-core processors, but I can't really remember if I did this and I can't verify because it doesn't boot into the OS. Silly me I already bought two X5690 and I got it today.
Any thoughts?
