Does the wifi works before in catalina? I think in big sur you should disable SIP on recovery mode the create snapshot to get sudo mount -uw / works. @MaLd0n ever told about it Quote HP Probook 430 G6 | Core i5-8265u | Intel UHD 620 Link to comment Share on other sites More sharing options...

Found on site out there : Fixing APFS Snapshot Procedure Boot into the Big Sur installer USB or run Big Sur in recovery mode Open a terminal, type `csrutil disable` and reboot When back into the installer, run `diskutil list` to find the location of the "Macintosh HD" disk, such as disk2s5 Mount it using `diskutil mountDisk ` such as `diskutil mountDisk disk2s5` then run `mount -uw ` such as `mount -uw /Volumes/Macintosh\ HD/` to mount it as read write Run `/System/Library/Filesystems/apfs.fs/Contents/Resources/apfs_systemsnapshot -v -r “”` Then, to delete the snapshots on the disk, run `diskutil apfs listSnapshots ` and take note of each UUID of the snapshots Run `diskutil apfs deleteSnapshot -uuid ` for all snapshots on the disk. Verify that there are no more snapshots by running `diskutil apfs listSnapshots ` it should return "No Snapshots for disk" Reboot into the Big Sur desktop and make sure that running `sudo mount -uw /` returns no errors and that running `diskutil info /` returns a disk such as disk2s5 and not a snapshot such as disk2s5s1 Make sure in step 5. you re-type (") before enter in your terminal Quote HP Probook 430 G6 | Core i5-8265u | Intel UHD 620 Link to comment Share on other sites More sharing options...
