![]() I would just leave it at High Sierra honestly but I want to back my phone up to it and the people at Apple as well as most third party advice says the only way to get around the alert that says my computer can’t read my phone without snd update is to update. ![]() My sister tried to combat this same problem on her laptop by upgrading and now it’s really slow and laggy, which doesn’t work for me since I need a lot of responsiveness with my drawing tablet. However it’s getting now to a point where it’s not slow but it gets hot when I open any app. I’m a digital artist and animator so I require a lot from it but it’s held up the last 6 years. Yes, it will erase the drive (which is what you need when you have a system that refuses to boot, and won't complete a normal system reinstall.I have a 2015 15inch macbook pro. So, take a deep breath, choose to restore from your Time Machine backup. The last backup, therefore, should take you back to your Mojave system, as it existed during the last backup - before you attempted to update to Big Sur, I think you can be confident about that. (AFAIK, Time Machine won't make a new backup until you have a working system installed, and so far, you don't have a working Big Sur system. You don't need to pick some older date, just leave it at the default, which should be the latest backup. The latest date would be the last completed by Time Machine. 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.

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.
