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?
