It’s common practice to sell or do a hand-me-down handoff of old Macs. Do you wipe the Mac’s hard disk drive so none of your personal data can be retrieved? Erasing and reinstalling OS X seems like a good idea, but guess what? All your old files are still there.
Making A CleanExit Mac
Generally speaking, there are a number of easy and straightforward ways to prepare a Mac to be sold or handed off to someone.
The easy way is to create a new administrative user, login as that user, and then delete your old user account (this assumes you’ve already copied your files to a new Mac).
That works and it’s fast. What doesn’t work is file security. Even after deleting your user account, files can still be found by hackers and ne’er-do-wells of the lower order. Even using Disk Utility to repartition a Mac doesn’t get rid of all your old files.
Full on security comes form utilities like CleanExit, a secure hard disk drive wiping solution which wipes out all traces of the data that once thrived on your Mac. Once used, even hackers with plenty of recovery utilities won’t be able to find your old files.
How CleanExit works is dead simple.
Select the disk drive to wipe, click. CleanExit works on Macs, Windows PCs, and most Linux PCs. The wipe may take awhile depending upon the size of the hard disk drive and the number of files, but when it’s done so are the files.
This utility also works on most IDE, SATA and eSATA hard drives, plus FireWire, USB, Flash media like thumb drives, and even digital camera cards. Mac users have something similar in Disk Utility which has Secure Erase Options which writes a single pass of zeros over the entire disk. It’s a bit more cumbersome to use, but it’s free and works well.
