simillary to the someone else problem described here: Unable to boot Mac OS and disk utility unable to repair disk after bootcamp delete windows partition The laptop is: MacBook Pro 15” i9 2019 Last used system: macOS Big Sur Problem: I’m not able to repair and run Mac OS. On startup there is a folder icon with the question mark. I was able to enter the recovery mode but there is no startup disk that can be found. Here are the steps that I executed:
- In the Recovery mode (Don’t know why but was shown the recovery mode for macOS Mojave but I’ve updated it to macOS Big Sur more than 1 month ago) I’ve ran the repairVolume commnad for disk1 in terminal but waited for 16h to complete but didn’t so I’ve started to look for different solutions. The error says allways: and didn’t stop, just running over and over.
Checking the container superblock, error: nx_block_count is 122061322, while device block count is 103759765
- I decided to go step by step in this problem: But the commands and responses looked like this
[-bash-3.2# gpt remove -i 2 disk0 disk0s2 removed [-bash-3.2# gpt -f add -i 2 -b 409640 -s 976695384 -t apfs disk0 gpt add: /dev/disk0: error: no space available on device
- As the previous error says that device block count is 103759765 and I cound’t use 976696384 so I’ve replaced it to 103759765 and ran again
gpt -f add -i 2 -b 409640 -s 103759765 -t apfs disk0
This time it works and response was that disk0 added
Restarted the mac but still the same error (folder icon with question mark). But from this time when I’m opening Recovery panel (command + option + R) It’s shown as macOS Big Sur.

I will be obligated if anyone can help with adding APFS container and running the system again!
