I assume that you have had your external backup drive (the one that you use for Time Machine backups) attached to your Mac, and it was finished with backing up, so should be reasonably up-to-date, as far as you can tell. If it is still stopped, then it is time to trust your time machine backup. Give it a 30 minute wait if you think it has stalled again, just to make sure. Might take an hour or two - be patient, find something else to do for a bit. Give the installer an opportunity to complete. Remember that the restore system has to download all the system installer files, so you have to allow for that time. It will reload the system, and should not disturb your own apps and files. If it is Big Sur (and NOT Mojave), then continue on with that install.
Not enough space to download mac os mojave install#
You will see the opening install screen, showing the version of system that will be installed. I don't think you need to restore from a backup yet.īoot to the recovery system. If it is T M and is a full backup, then that message should actually say, this will restore everything as it was back the date you are choosing, correct? I’m only asking because this falls into the what I don’t know that I need to ask dept. So, aren’t I restoring all data, files, photos, apps with the time machine full backup restrore? I don’t want to end up seeing a computer that’s been restored to 2014 and nothing on it.
But the “erase” and “be sure you have everything backed up” is terrifying. I’m restoring from a full backup aren’t I? I see the time and date. Huh? I thought I did have everything backed up. that is terrifyingly is it asks, “ Do you want to reinstall from a full back up.” Yes… Continge… This will erase everything on the hard drive. I tried To reinstall Big Sur and it started from where it got to at 4pm, then goes to the screen where the white line is halfway. I can do command r and restore from time machine is a choice.
