My MacBook has to go to Apple repair to have the keyboard replaced. I am advised that there is a chance that my data and applications might be erased. I backup with Time Machine to an external hard drive, and use Dropbox with ReunionTouch. So I think my family file should be safe in Dropbox. But I’m not sure. And what about the Application itself? I wonder if someone could advise please. I can’t work out if third party applications are also backed up with Time Machine. And then there is iCloud and iCloud Drive, which I could also use. As far as I can see however, it is only Apple applications that are synced with iCloud.
