Hi all,

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 ?

Thanks

Have you tried running a full Web recovery to put it back to factory defaults?

How old is the iMac?  What model number is it?  Some of the earlier models can't run anything beyond snow Leopard.

Hi Brian,  When you say factory defaults i presume you mean wipe it ? If so then that's not possible as it's got a lot of programs on that the client can't get licence keys etc for to re-install.
I'm thinking it might be the SSD firmware ? it's brand new but seems a common problem.

Your problem may be startup software that is incompatible with Mavericks. Try rebooting in safe mode by booting while holding down the shift key to prevent startup applications from loading.

I would first make sure the newly added memory is working well, then make sure the SSD is compatible and well cloned from the original disk.

if you remove the newly added memory, does the Mac boot as expected?

Thanks all, it seems Crucial SSD's which this is aren't all compatible with Apple and certainly Mavericks, we've now put a Samsung in (cloned the failed disk that has Mavericks on) and it's working fine.
Thanks
