Once you have completed the steps and the process ends without error, your USB will be bootable, and you can insert it into your Mac. You can install or upgrade to the latest version of Mac (Ventura, Monterey, Big Sur, Catalina, or Sierra).

Change the partition type of your USB

If the above process doesn’t work, then you don’t need to worry about it; change the partition type of your USB from MBR(Master Boot Record) to GPT(GUID Partition Table) and again rerun the above process.

Below is the complete guide to creating a GPT partition in your USB.

  1. Click the  Windows logo.
  2. Search for Command Prompt, right-click the top result, and select the Run as an administrator option.
  3. Type the following command and press Enter: “diskpart”
  4. Type the next order to view all drives connected to your computer and press Enter: “list disk
  5. Type the following command with the number assigned for the USB flash drive and press Enter: select disk 4In the command, change “4” to the number corresponding to the USB flash drive.
  6. Type the following command to clean the drive and press Enter: “Type the following command to convert the drive to the GPT style and press Enter: convert gpt
  7. Type the following command to create a primary partition and press Enter: create partition primary.

Once you have formatted the USB flash drive with a GPT partition, you can use the instructions mentioned above to use TransMac to create a bootable media, but this time skip steps 5 through 10 and continue on step 11.

After the process is complete, which it’s something that could take up to an hour, connect the USB flash drive and power on your Mac by holding down the Option key, and select the USB drive to begin installing macOS.
