Mac menu options

I have a client on a Mac.. I don't have a Mac and am unable to help w/some of her problems.

1. She did a "shared workbook protection" and now can't undo it...
2. where is the mac equivalent to Tools, Options?

thanks,
tracy

It's a little less clear on the Mac. It could be in a couple of places; try this

Excel (menu to left of File) > Preferences

That may not do it (check under security).

Otherwise,

Tools > Protection > Protect and Share workbook

I'll see what happens. thanks
