Change user associated with Google Drive account (OSX) when old account does not exist

I've got Google Drive installed on Mac OSX 10.8.4 -- I no longer work and company X and want to associate Google Drive with company Y account.

I no longer have access to the old account so I can't go through the normal process of signing in and deactivating the account. I have tried deleting and uninstalling and still am being asked to sign in as the old user.

What did I miss? Where does Google Drive store the association with the old account?

Try removing com.google.GoogleDrive.plist from your homedir library preferences folder (~/Library/Preferences/) and then uninstall and reinstall the Gdrive app.

VDR is partially right. If you are using Google Drive on a Mac you need to delete some files in order to re-sign in.

Close Google Drive by clicking on the icon in the menu bar and choosing Quit Google Drive. There is no need to uninstall the app.

In your home folder (/Users/username/) go to Library/Preferences/ and delete two files: com.google.GoogleDrive.plist com.google.GoogleDrive.plist.lockfile

Then navigate to another folder in your home folder, Library/Application Support/Google/Drive/ and delete all the files and folders.

Now restart Google Drive and you will be able to sign in with your personal account.

Here are the steps I used (overlaps some with what's mentioned above, but the important difference is clearing WebKit cookies):

1. Close the Google Drive login window (if it's open)
2. Use the menu bar icon to quit Google Drive (if it's running)
3. Delete the folder ~/Library/Application Support/Google/Drive
4. Delete the files ~/Library/Preferences/com.google.GoogleDrive.plist*
5. Launch Safari
6. Open Safari preferences and clear cookies/cache: Safari Menu > Preferences > Privacy > Remove all Website Data...
7. Quit Safari and re-launch Google Drive
