Wiping a mac

[FWilson]

When you recover/ format a mac, is all data properly wiped?

I'm looking to sell my mac but i'm concerned that some of my private data will still be on it after recovery. I know with a PC data can often still be retrieved after stuffs been fully deleted, but is it the same one Mac?

Thanks in advance!

I think that it still might be possible to recover some of your data unless you specifically had the space zero-ed over during the reformat. You can try to zero out the free space using Disk Utility, selecting your main drive, and using the "Erase Free Space" option. This should be sufficient in ensuring that your data is unrecoverable.

I think there is an option when you reformat of how many times you can wipe everything off. not sure what the max is but I do know it would take longer of course
