I've followed the GitHub instructions for setting up my account, and I'm able to clone, but I'm unable to push remotely.
When I do a "git push" I get the 403 error. It has the correct URL. I tried a "git credential-osxkeychain get" to see what it was giving, and this prints out the wrong credentials.
I believe what happened is the first time it asked for the credentials, I thought it was another application asking, and it put the wrong ones in.
I just need to reset it so that it uses the correct keychain item for my GitHub account.
I've tried:
git credential-osxkeychain erase
git credential-osxkeychain set
The program never gives any prompts. Set will say "bad input" if I don't do the right thing. I tried putting in "password=password", etc., but then when I do a "get" I still get the old ones.
I can't figure out where these are being stored, as they are not in .gitconfigure. Further there are no recent keychain items that could be it. (I have several GitHub accounts in my keychain and it is not using any of them.)
Try running /Applications/Utilities/Keychain Access.
On Mac, use the command git credential-osxkeychain erase.
OR remove manually from keychain from Applications ? Utilities ? Keychain Access. Then remove the github.com keychain. Then use push; it will ask for the keychain access; then deny.
It will ask for the new username and password, add it then pushes a file for that.
After git push I found this error. Then I use the upper case-
issue:
remote: Permission to user1/file.git denied to user2(previously exist user ). fatal: unable to access 'https://github.com/xxxxxxxxxxxx/': The requested URL returned error: 403
git-credential-osxkeychain stores passwords in the Apple Keychain, as noted above.
By default, gitcredentials only considers the domain name. If you want Git to consider the full path (e.g. if you have multiple GitHub accounts), set the useHttpPath variable to true, as described at http://git-scm.com/docs/gitcredentials.html. Note that changing this setting will ask your credentials again for each URL.
Try this in your command line.
git config --local credential.helper ""
It works for me every time when I have multiple GitHub accounts in OSX keychain

I'm not sure how to erase through the command line, but it's fairly easily to do it through the Keychain Access app. Just go to Applications -> Utilties -> Keychain Access, then enter "github.com". You can either delete the invalid item or update the password from with the app.
From Terminal: (You need to enter the following three lines)
$ git credential-osxkeychain erase ?
host=github.com ?
protocol=https ?
?
?
NOTE: after you enter “protocol=https” above you need to press ~~RETURN~~ TWICE (Each '?' is equivalent to a 'press enter/return' )
