Hello All,
I need some help. I ran into this error and after spending hours surfing through these forums I found the below article:
http://support.apple.com/kb/ts3926
However, when I open my DiskUtil I get "This partition can't be modified". See Screen Shot below
Any suggestions would be greatly appreciated.
Currently running Version 10.8.5 on a MBA from Mid 2012
MacBook Air, OS X Mountain Lion (10.8.5)
That is probably the partition containing the OS you are booted from. Try booting into the Recovery Volume.
Boot into the Recovery Volume (command - R on a restart or hold down the option/alt key during restart and select it) to run Disk Utility from there.
Thank you Eric Root for the quick reply. However that didn't work. As you can see from the discutil command below for some reason the drive is disk02s0 and that partition does not show up in the above Disk Utility App. I don't know how to "decrease" the partition volume without it being in the Disk Utility App in order to load Mavericks. I am at a loss for now....
Is your internal drive encrypted? Are you using FileVault? This might help Eric Root with further troubleshooting.
Hey Keg55,
No it is not encrypted and I do not use FileVault on this mac.
Thanks,
