I dont know if it will help u, i had the exact same problem! Nothing seems to work... What i did whas remove my 8gb ram and replace them with the original 4gb.. Boot up the device, download the mavericks upgrade and after that it started to upgrade... Now busy installing so i do not know if its 100% guaranteed fix.. If i do not post back, it worked for me!



Give it a shot people, hope that this will help you...

Same problem here.

Opend Mac Mini in recovery mode, repaired permissions and checked HD: everything ok. "Hardware-test" showed no problems, too. Had some problems with the 10.8.5 update recently and made a complete new install two weeks okay.


Frustrating 😟



I am watching this thread, too: https://discussions.apple.com/thread/5466903
