Changing opencore bootloader page name

[jackwu2006]

After I update my hackintosh to macOS 12.5.1, I also changed my disk name to macOS 12.5.1. However, in bootloader page, the disk's name is still 12.5, who can tell me how to change it?

Please add a signature to your profile (Account details).

 

Easy way: install Intel Power Gadget, after reboot OpenCore has the new name.

 

Not as easy way: OpenCore uses .disk_label file if it exists, otherwise it tries .contentDetails and, if this doesn't exist, it tries .disk_label.contentDetails.

• config.plist: change csr-active-config to 6F020000 (having csr-active-config also in NVRAM >> Delete >> 7C436110-AB2A-4BBB-A880-FE41995C9F82)
• reboot
• mount Preboot volume from Terminal (I'm not sure if that this is required, I see Preboot volume without mounting it but other users have had to mount that volume)
• edit /System/Volumes/Preboot/UUID-number/System/Library/CoreServices/.contentDetails and /System/Volumes/Preboot/UUID-number/System/Library/CoreServices/.disk_label.contentDetails
• change the volume name to the desired name
• reboot.

The new name is displayed in text and graphical picker.

 

Note: UUID-number is the UUID of the APFS volume group where Preboot volume is located, you can do "diskutil list" and "diskutil info diskx" where diskx is the APFS Container Scheme.

I suggest wait for a new macOS update which updates your disk name on OC as well. If you want to keep changing your disk name with every update then I suggest, change disk name first then do the update.
