Hello
How can you format and erase all information kept on your MacBook Air, and reinstall all the basic programs and lion OS again?
All that to opnimize your Hard Disk memory?
Thank you
Jorge
MacBook, Mac OS X (10.6.8)
I would back up your data unless you really don't need or care for any of the data
-install lion/do the upgrade through the app store
-once you have upgrade to lion reboot and hold command and R
-you will boot into the recovery partition and you will have an option to use disk utility from which you can repair disk permissions and erase-format your hdd and reinstall lion
here is a link that will be helpfull
Thank you!
