iMAC not starting after upgrade to Mavericks
Posted on 2016-10-28
I've upgraded an iMAC from 8GB to 16GB and have cloned the exisitng SATA hard drive (using carbo copy cloner) onto a crucial 1TB SSD which then all booted up fine. The iMAC WAS on Snow Leopard and so i downloaded and upgraded the OSx to Mavericks but now it won't boot, it just sticks on the Apple logo (no spinning circle). I have ran repair disk and repaired permissions and it's detected the SSD as the boot disk but it just sticks there.
Any ideas ?
