Confirm my identity on Facebook?

[SilverTonguedDevil]

It's obvious someone has hacked your account, yet you are indignant that Facebook wants to stop the hacking. You should be glad they want to keep your account secure. Are you giving your login password to others? OR letting someone look over your shoulder as you log in? If not, it is probably one of the hundreds of apps people use to generate FaceBook break-ins.

"it also requires me to have Mac OS X 10.7"

No, it doesn't require that you buy OS 10.7. It just has some login info that is in conflict with what you have used, so just ignore that. Instead, send your ID documents.

You can use other ID documents:
