My friend has a 2011 mac mini,  He got it brand new from apple. After 3 months we had to send it back and have the HD

reformated because it froze up . We got it back restored from time machine, it all works for about 30 day's, than kernal panic.

Sent it in to apple repair they replace the logic board. Get it back the os come up when we turn it on so we say OK, lets

restore fromTime Capsule time machine backup. He was using on his new macbook pro. We called apple care to make sure we had all

of our ducks in a row. We started the restore and went fine the computer rebooted and it crashed with a kernal panic. Shut it down

restarted it same thing crash... What the heck is going on. Now we have to send it back again. 


Thoughts... loosing faith.

    Kernel panics can be difficult to diagnose, but generally they are hardware related, not software. Given this has been with different Macs I would suspect some external peripheral as the source of the problem. Even something as innocuous as a USB hub could be the source of your friend's problem. Noisy or bad power would be another potential suspect. It could even be some third party kernel extension (kext) or driver that is being reinstalled from the backup. At this point finding the problem comes down to a trial and error process. I would start by removing any and all peripherals and if the system is stable add them back one at a time until there is a KP. If it isn't hardware then I would start with a clean install of OS X, re-install all the software from original sources -- NOT Time Capsule -- and finally reinstall ONLY the data files from Time Capsule. If the system is stable at that point, I would erase the Time Machine backup and start over with a backup from the now stable system.


    I forgot to add, be sure you have a really good surge protector or UPS just in case the problem is noisy power.

    Second ? When we were talking a apple care  we asked about using his MacBook Pro and the time capsule also. He suggested that we partition the time capsule and put the MacBook on 1 partition and the Mac mini on the other.

    He uses both for his business so it's important that the both have the same data at all times.


    Partitioning the Time Capsule is unnecessary. Each Mac backing up to a Time Machine drive will store its files in its own unique Sparse Image Bundle that can grow, or shrink, as the situation requires. It is a LOT more flexible than partitioning and accomplishes exactly the same thing.
