Turning off time machine I cannot turn off time machine. I'm using Catalina and a seagate back up drive plus. I have researched this and many sites. They say go to system preferences, time machine, turn off. When I go to system preferences, time machine, I don't get a turn off button. Is it just me? Please help. Thanks in advance.
There should be a checkbox saying "Backup automatically". 

Uncheck it.
