Using OpenCore gives me an error, trying to find 'camera' in 'System Information'. In 'FaceTime' I see Epocam and iSight, but nothing works. Perhaps a problem with trust.
Any idea?
 
Many thanks joevt, Ive got a bit further and i'm getting:

/volumes/preboot/83706E9F-747C-40D7-8431-8908C12C21BA/System/Library/Coreservices/.disk_label.contentDetails: Permission denied

I'm sorry for the 'silly' questions but i don't really know what i'm doing!

Thank you so much for sharing this information, however I'm a bit confused how to go about fixing my problem. Are you instructions only meant for Catalina and above, as I'm struggling to make sense of what I'm meant to do in Mojave.

My original SSD boot (that I cloned to the M2) is called SSDOS. My NVMe cloned drive is called SSDM2. I'm using Mojave.

SSDM2/System/Library/CoreServices/ shows invisible files .disk_label and .disk_label 2x and .disk_label.contentDetails. When I open .contentDetails in Text Edit it already correctly contains "SSDM2", so I assume I don't need to do anything. Both .disk_label and .disk_label 2x contain indeterminate gobbledegook.

Can you provide some more guidance please.

I am very sure OpenCore Boot Picker will look in the Preboot Volume for the .contentDetails file.
Apple Boot Picker uses the Core Volume (SSM2 in your case).
So, OpenCore will display the contents of .contentDetails, or .disk_label, or .disk_label_2x, or .disk_label.contentDetails.

The content of .disk_label & .disk_label_2x (for Retina) files are rendered graphic bitmap of what the Boot Picker displays. The contents of .disk_label.contentDetails is textual representation of what's in the rendered bitmap files.

So you have first to mount that Preboot volume and check there.
Here's my Mojave SSD:

Note I do not have a .contentDetails file because I did not need it since I do not have the Preboot volume label "corruption" that you are seeing.

So mount your Preboot volume and then dump the .disk_label.contentDetails like I did above.
I suspect that the file contains what is displayed by the OpenCore Boot Picker (SSDOS).
If it is, then create the text file .contentDetails that contains your desired name (SSDM2).

That is what's used by the default Apple Boot Picker when booting via Apple EFI bootstrap.
When booting via OpenCore, OpenCore's OpenCanopy Boot Picker will use that file too if it does not find .contentDetails file.

That looks correct since .contentDetails file has not been created by you.
macOS does not create that file but OpenCore looks for it.

What command did you use ?

Hi, I used these:-
diskutil mount disk3s2
ls -iahl /volumes/preboot
more /volumes/preboot/837*/System/Library/CoreServices/.disk_label.contentDetails
Click to expand...
prefix the more command with sudo.
That is:
Code: 
sudo more  /volumes/preboot/837*/System/Library/CoreServices/.disk_label.contentDetails
...and enter your password when prompted.

If that does not work then SIP needs to be enabled.
 
I tried the Super User Do (SUDO) command and it worked thankyou Mac.
Didnt think of that!
Ok, it shows the name of the volume as MacintoshHD, how do you go about changing that?
Sorry to be a nuisance!

Edit: if I run this command and put the new name into the “My Boot Disk” I assume this will manually change the name:-

sudo echo "My Boot Disk" > /System/Library/CoreServices/.contentDetails

the command to use in your case is :
Code: 
sudo echo "My Boot Disk" > /volumes/preboot/837*/System/Library/CoreServices/.contentDetails

Try it and reboot into OpenCore Boot Picker.
 
sudo echo "My Boot Disk" > /volumes/preboot/837*/System/Library/CoreServices/.contentDetails

Or .disk_label/.contentDetails ?
 
Hi,
I tried the command suggested, but its stating 'No such file or directory! as :-

Paul$ sudo echo "OS Catalina" > /volumes/preboot/837*/System/Library/CoreServices/.contentDetails


-bash: /volumes/preboot/837*/System/Library/CoreServices/.contentDetails: No such file or directory

Apologies. I forgot wildcard '*' are not allowed in that command.
so, do this :

Code: 
echo "OS Catalina" > .contentDetails
sudo cp .contentDetails /volumes/preboot/837*/System/Library/CoreServices

Is this also the correct syntax and process for a Mojave boot drive?
