Ive had the 5k, i7, 295x, 24GB, 500SSD for a week now. I had the wake from sleep crash a couple of days ago. last night I set it to "prevent computer from sleeping when display goes to sleep. At about 3 am the computer rebooted. I got the loud chime and screen lit up waking me up I went to library/logs/crash reporter and found this. "Feb 25 03:01:00.234220 Richards-iMac.local discoveryd_helper: Basic RemoteControl com.apple.discoveryd_helper Starting XPC Server Feb 25 03:01:00.234465 Richards-iMac.local discoveryd_helper: Detailed RemoteControl com.apple.discoveryd_helper XPC connection 0x7f86320001c0: start (pid=48, <unknown> not root)" This is really frustrating on a computer of this price. Im sure Apple will tell me to reinstall the OS but Im not sure that will do any good and thats time consuming. Ill start by unplugging the Lacie 2 TB Porche drive and see if the crashes stop. Next I will remove the Crucial 16GB ram but the hardware and meatiest say its ok.
