Upgrade from High Sierra to Monterey hangs
I was having some issues with a Macbook air 2013 High Sierra, it seemed to not recognize the hard drive at some times and did not boot (folder with question mark). Made some unnecessary drive permission fixing, that seemed to solve it. Now tried to upgrade to Catalina but Apple Store sent me directly to Monterey. I have enough free space (around 150 GB). I also had a 140'ish MBPS internet connection. The mac rebooted and began upgrading, but the progress bar advanced very slowly, more or less until 40%. I had to move the mac to another wifi connection (another city), but the progress bar just does not advance. I already did a first reboot to no avail. What do you recommend I do next?
I'm thinking there must be some key strokes or maybe rebooting several times so the OS knows it has to fix something.
