Good day!
I've been having some odd troubles with the iMac of the family - any and all troubleshooting attempts that I could think of and find on the web have not been of much help as of yet.
The unit is a 2011 27" iMac, sporting a i5-2400, 4GB of 1333MHz RAM, an AMD Radeon HD 6970M, and a 1TB HDD. The OS installed when the issues began was Yosemite (don't recall the exact version number).
Issues began rather abruptly - all was smooth sailing then all of a sudden, reboots on me and enters a reboot-loop.
I've whipped-up a document (viewable here) detailing my issues and troubleshooting attempts, maybe their's something I missed that could be useful!
Cheers!
iMac
