When it's in screensaver mode, it's goes to sleep after 45 minutes or so. But whenever it's been asleep for a while, it always has to restart when you try to wake it up, and I can't find a way in the Settings to keep it from going to sleep, unless I've just totally overlooked it. Any help anyone can give me will be gratefully appreciated.
Mac Pro, OS X Yosemite (10.10.4), 2.8 GHz Quad-Core Intel Xeon

Thanks for the info. I was able to change the setting to keep it from going to sleep, but do you have any idea why this is happening? I always used to be able to put it in sleep mode and then wake it back up later on with no problem, but now every time it goes to sleep it has to restart. There has to be something that's causing this, and if you can think of anything else that may fix it, I'd sure appreciate hearing about it.
By "it has to restart" you mean the monitor is not waking up? if you turn on Mac sharing, you can actually see the Mac is waken. If that's the problem you are seeing, rolling back to 10.10 will fix the sleep/wake issue. Why it's causing this I have no idea, the update broke the wake/sleep process.
My MacPro (early 2008) has to be restarted whenever it's been in sleep mode for a while.
