I am giving my son my old macbook air, and wanted to free up as much hard drive space as possible.  I deleted my user account, and I expected there to be about 225 GB of free space.  There is not, however.  When I check the storage, it says there is nearly 78 GB of "Backups."  My question is whether that backup is from my old account, and ultimately, where can I find this to delete it to free up the space.


I also have another macbook air that I plan to sell.  What is the best way to erase the contents of the computer without deleting the OS. I plan to sell it, and obviously don't want the next purchaser to have access to my old data.


Thanks in advance.

MacBook Air, Mac OS X (10.7.2), 2 11.6
