Hello!
I got a "new" Mac Pro 3 weeks ago. It's a mid 2010 model. (confirmed by serial number). It comes with 10.13.6 already installed. Since my goal was to upgrade it to 10.14.6, I've bought a Nvidia K5000 flashed with an original Apple OEM rom. The video cards runs fine, exactly like the version sold by Apple 10 years ago.
2 days ago, I installed the k5000, then installed Mohave on a spare partition (to keep HS just in case) . The firmware upgrade went well and Boot ROM is now at 144.0.0.0.0, SMC (system and CPU tray) are at 1.39f11. Mohave installation went also well, no issue. Then I rebooted.
The Mac ran OK, except that I have a serious issue with the sleep/wake up mode (with Mohave AND HSierra). Now it's impossible to wake up the Mac after it went to sleep. I know the necessary steps to find/isolate the source of sleep/wake up problem (Well, I always managed to solve this kind of issue a my full time job where I support Mac since many years).
The sequence of event is this one:
I suspend using Apple menu/Suspend. (But I could also let it go to sleep by itself or program it to sleep at hh:mm),
After a few seconds, fan + HD stop then the front LED light starts to pulse slowly as usual (enter sleep mode)
Then I hit the space bar or click the mouse to wake up de the Mac.
I heard a "click" the LED start to stay on permanently, but HD and fans don't start, of course no video signal.
I need to press and hold the start button until de Mac Shut down.
Then if I press the button to start it again, most of the time, nothing happen.
To make it starts, I need to hold the start button for about 10 sec, then I heard a "click (coming from the PS I or the top right of the backplane board, it seems to reset the PS), Then I press the start button again and it starts.
At first, I thought that the problem was related to the video cards(since it's a new device). So I switch back to the Radeon 4970 and 10.13.6. But it didn't solve the issue.
Then I removed pcie card, SSD and kept just 1 HD + actual ram (32G). Same issue. I also tried a GT-640 video cards since it doesn't need to be connected to the Mainboard and can run with the PCIe power only. Same issue.
I double checked all Power management parameters. Power Nap, hibernation and everything else is set correctly. Since usually this type of problem is related to SMC, I reset it (many times), reset NVRAM, PRAM and also RTC. I installed a fresh battery on the mainboard. Also check if any diagnosis led was "on" inside of the Mac. I've read the tech service manual and can't find any clue about how to solve this issue.
Since the problem now exist in High Sierra and was absent before, the only possible conclusion is that it's related to the firmware update. Or maybe to the Power Supply (but it would be a strange coincidence that it failed just after the upgrade). Also, in 2-3 occasion, when I tried to put the Mac asleep, it didn't work. The screen went blank for 1 sec and came back on. I rapidly tried a second time and then it went to sleep.
So, it seems that the SMC doesn't do it's job correctly. I also remember that at my full time job a similar issue happened. One of our Mac Pro refused to start just after we upgraded it to 10.13.6. The Mac was sent to an Apple certified repair center. It came back 2 week later with a note saying "Bad video cards". I was sceptical that the card caused this issue. Maybe they also replaced others parts, I don't know.
Since it's not possible to downgrade the firmware, I have no way to know for sure if it's related to it or not. If revert to an old firmware would solve the issue, then I would know that it's related to it.
I have a spare Mac Pro. So I can switch parts between both if needed, and I will probably try to replace the power supply this week, just to see. But to have an hardware failure just after a firmware/system upgrade would be a very strange coincidence.
I tried every trick I know to solve this issue without success. How could I check the integrity of the SMC firmware ?
Any help would be appreciated.
Thank to all!
