  • There are a few options to attempt to manage partitions and convert MBR to GPR on a Mac.
  • On a Mac, using a specialized program like the one outlined in this article is one approach to convert partitions from MBR to GPT.
  • MacOS users can simply convert MBR to GPT using the system’s Disk Utility feature.
  • Following our step-by-step instructions, changing an MBR partition to a GPT partition is simple.

If you have a Mac PC, you should be aware that your main partition must be GUID (or GPR) and not MBR, which is largely particular to Windows, whenever you need to install your operating system.

There are, of course, circumstances where you must convert from MBR to GPR. These circumstances consist of:

    • Changing your Mac’s operating system to a newer version that doesn’t support MBR
    • Windows installation on a Mac
    • The PC’s hard disk can be replaced but is MBR by default.

Due to this, we’ve chosen to create a step-by-step tutorial on how to change an MBR partition on a Mac device to a GUID.

I highly recommend Paragon’s Hard Disk Manager to manage the disk partitions on your Mac.

Paragon offers effective methods to backup, resegment, and wipe your drive with an intuitive interface. Deleting or lost files can also be recovered with just a few clicks.

One of the most popular tool options is to convert and redistribute the wasted space between the partitions, and you can take full advantage of this.
