I'm new to the scene and running a Dell T3500 with OSX installed using Unibeast. Mostly everything runs smoothly, but I updated to the newest version of OSX this weekend, and when it completed the update and rebooted I received a boot error stating my drives were not set up in RAID. Hitting F1 would boot into Clover, but boot would fail at the Apple logo. After further investigation in the BIOS I realized all the settings had been reverted to defaults, including turning off hyper-threading, resetting the boot order, and turning RAID on. I turned everything back to what it should be and now it boots fine. Has anyone else running a T3500 or any Dell experienced this when updating? And why might this be happening? Should I be concerned? The fix was easy enough after digging out an old PS/2 keyboard from the basement. If there's any further information you need me to provide, I can do my best to do so.
