Need help to burn dmg to usb for making Mac bootable USB drive
Apple no longer provide dmg disk for its modern macOS versions. This is why it is so hard to create macOS bootable USB any Windows PC and Mac now! One popular way is to find a macOS dmg file and burn dmg file to USB. This works on all Windows OS and macOS.
For doing this, I highly recommend using the UltraDMG app as I made a couple of macOS bootable USB on my Windows 10 PC. Here is the tutorial: https://www.sandeski.com/make-macos-bootable-usb-on-any-computer
You can also ask the team to share you the macOS DMG file.
Enzozo You can use the built-in Command Prompt or Powershell utility to burn dmg to USB on Windows 10/11 along with the free 7-Zip app.
First, extract the content from macOS DMG file with the 7-Zip app. After that, insert your USB drive into the PC and format the drive with diskpart command:
select disk 1
clean
create partition primary
select partition 1
format fs=fat32 quick
active
assign letter=U
exit
Now, copy the extracted files to the USB drive:
xcopy C:\path\to\extracted\files\* U:\ /E /H /F
This process will burn the contents of the DMG file to the USB drive. Make sure to replace the placeholder paths and file names with the actual ones you are using.
Did all the diskpart commands up to Step 6 which fails - "The selected disk is not a fixed MBR disk.
The ACTIVE command can only be used on fixed MBR disks."
