how to upgrade 10.6.8. This disk can't be used to start up your computer
Hi all
Mac Air 10.6.8 1.86 GHZ core 2 duo
4 GB
how to upgrade 10.6.8. "This disk can't be used to start up your computer"
I try follow some article to partition using disk utility but it failed and ask me to reduce the disk space. Try reducing but no success.
I try rebooting several and power off computer to boot up in recovery mode by hitting COmmand + R but still no success.
I"m very confuse how do I upgrade to the latest OS?
Do I need to purchase some software upgrade?
Any help would be greatly appreciated.
Thank you in advance.
