Nearly all storage used after factory reset.
Hi,
My girlfriend had a problem with storage on her MacBook Air from 2015, so I recommended her to back up all of her important things and just reset the computer to factory settings, as deleting all the junk she has there would take a lot of time.
We did that, and to my surprise, after the reset, the storage says only 21GB out of 121GB is free, 70GB is taken by "Other".
Does anybody have any clue why is that? I can see that when checking the storage there are 3 "Macintosh HD" storage each with approximately 20-25GB of free space, is it possible her disk was partitioned into 3 separate parts?
Thank you a lot for any help and have a great day to whoever reads this! ;)
