If you are facing issues with your Gmail account in your Mac system, you will be able to get proper solutions from Gmail customer care. For example if you’re not able to log into your Gmail account, you will have to first see that if you are entering the correct password. See if the caps lock key is on or off. Turn it off, if it is on as passwords are case sensitive and you have to use correct capitalization wherever it applies. Enter the symbols and numbers correctly and check if the num lock key is on. If you are sure that you are entering the password correctly, and still are not able to log into your Gmail account in Mac you must contact Gmail customer support.
