Apple Mail refuses to accept my password for Gmail account
I can't believe Mountain Lion has such a silly problem. Apple Mail will not accept my Gmail password no matter what I try. All I get is "Mail can't connect to the account "Gmail"" Enter the password for xxx@gmail.com. (where xxx is my username) It doesn't matter if I have just my gmail username for username or the whole address. Worked just fine in Lion. Does it work for anyone? Maddening. Perhaps I should simply not use it?
iMac, OS X Mountain Lion (10.8)
