Hello,

Does anyone know how to resolve the latest or Main error Message described below? Or have any suggestion to efficiently complete my Todo list below?



**Latest Error:**

container /dev/rdisk1 is mounted. repairs in a mounted container is not supported yet.



**Latest Context:**

I was running the code as prescribed in this article. https://osxdaily.com/.../how-to-repair-a-mac-disk-with.../ to resolve the Main Error Msg.





**Main Error Msg-- MacbookAir won’t start:**

Your computer restarted because of a problem. press a key or wait a few seconds to continue starting up



**Possible Trigger/cause:**

electricity suddenly went off in the house & this issue occurs shortly afterward



**Error Msg diaplyed after restarting in recovery mode:**

First aid process has failed. If possible back up data on this volume



**Todo**

Does timemachine recovery restore chrome extensions & bookmarks? Custom shortcuts ?

If not, how to backup those when the computer won’t start?

Should I unmount the container then?

Hello and welcome.

-Which exact model MacBook Air?
-Which version of macOS?
-Do you have a current Time Machine backup?
-If not, do you need to save any of the data?
-Have you tried starting up in macOS Recovery mode and running Disk Utility from there?

It sounds like the drive is corrupt and cannot be repaired by Disk Utility First Aid. You may need to totally erase it and reinstall macOS. If you cannot startup properly, there isn't any easy way to backup data. You would need an external drive with macOS installed to startup from, then attempt to mount/read the internal drive and save data.

If you were signed into Chrome with a Google account, it automatically saves your bookmarks and Chrome Extensions. You would be able to sign into Chrome on another computer and they will automatically sync back.

-Which exact model MacBook Air? > A1465
-Which version of macOS? Big Sur
-Do you have a current Time Machine backup? Not current, it's 3 months old, but I am ok to lose the rest of data if retrieving is cumbersome
-If not, do you need to save any of the data? Not necessarely
-Have you tried starting up in macOS Recovery mode and running Disk Utility from there? yes, that's where the error message comes from-- since the initial issue is that I can't restart the mac; so there is no other way that error could have been generated.

Thanks for the other comments

OK, thanks.

The A1465 can be a few different models:
-MacBook Air (11-inch, Mid 2012)
-MacBook Air (11-inch, Mid 2013)
-MacBook Air (11-inch, Early 2014)
-MacBook Air (11-inch, Early 2015)

Since you started up from macOS Recovery and ran Disk Utility there and it fails, then the next step would be to try and completely erase the drive and then run First Aid to see if the error persists. If not, you can reinstall macOS or attempt to restore from your Time Machine backup.

The other option would be to try and install macOS on an external USB drive, startup from it, and then see if you can retrieve any of the data off the internal.
