Mac OS X
Q: I'm selling my computer but when I get to step 3 (reinstalling OS X) an error message keeps coming up telling me I cannot install an older version of os x on the computer because there is a newer version installed. Help?

What to do before selling or giving away your Mac - Apple Support
you can't downgrade to anything less than what your computer shipped with and if something newer is on there now you need to partition it off the drive entirely.
