Mac Pro 2009 won't wake from sleep after El Capitan
HI All,
I just upgraded my early 2009 Mac Pro from latest Yosemite 10.10, to official ElCapitan 10.11. Now when the Mac Pro goes to sleep, the fan kicks into high and the computer becomes unresponsive. My single screen does turn off properly. Neither my apple Bluetooth keyboard nor Logitech MX mouse will wake the system. I have to hold down the power button to get the system back running. This happens whether I manually put it to sleep or let the OS do it after the set time. Sleep worked fine on 10.10 prior to the upgrade. I do have two external drives which use usb. I switched them to FireWire and I still have the problem. I have to fully shutdown the computer all the time now. Has anyone else experienced this? Any ideas? Help is appreciated.
