Need some help. I made a partition of my hd (with high sierra), this new partition is an apfs where I installed another OS (Mojave). I had some problems with restarting, so I could have accessed to the disk recovery and I thought about deleting the new partition. I rebooted and it worked for a couple of times. Now I am stuck with rebooting, it's like a loop, and can't access to the original high sierra. I cannot even use the recovery mode or the internet recovery mode. The only mode I can access is the single mode user. I tried the recovery, it says the volume is ok but there are some problems with the apfs... I don't know what to do. Is it possible to backup the files from single mode user and reinstall the os? Or boot the system in a way or another? Hope what I wrote makes sense cuz I'm not too familiar with this world 😅 Thanks!

  • What model of Mac is this? (Only c. 2012 to 2018 models can use both those OSes.) Probably best to wipe the disk and reinstall one OS.

  • If you can reach single user mode or recovery, then try to posting the output from the commands diskutil list internal and sw_vers. Commented Jan 27 at 15:47
  • Thanks! It's a macbook pro from 2013. Was working really good, till I did that... 😅 I'll try with the command suggested. Commented Jan 28 at 4:19
  • I don't know what happened, but now it's working. After booting I checked the hd with disk utility. It says something about overallocation Commented Jan 28 at 13:27
  • I used the commands @DavidAnderson suggested. It shows the scheme and there are 4 apfs volumes: the volume that I'm using disk1s1. A volume called preboot disk1s2, one called Recovery volume and one VM. Commented Jan 29 at 1:34
