Even the SSDs or hard drives that are smaller than 2TB are using the GUID partition map scheme for their hard drives for many other advantages, like easy data recovery and more. Since PowerPC Macs have been replaced by Apple with Intel, and then by its own silicon, the answer to the question of which is best between GUID Partition Map, Apple Partition Map scheme, and Master Boot Record is the GUID Partition Map scheme.īoth the latest Windows and Mac computers use the GUID partition map scheme for their hard disks without exception. ![]() If it is a PowerPC-based Mac, the Apple Partition Map scheme is a better choice. ![]() Also, Intel-based Apple Macs are better off with a GUID partition map scheme.

The GUID doesn't have any limitations by itself the only limitation can be on the OS side. The GUID partition scheme's limit is much higher compared to MBR, with support for a hard drive size of 9400000000 TB, and for users to create unlimited partitions. The MBR can only support hard disks up to 2 TB in size. MBR was the default for decades until the hard drive's storage capacity crossed 2 TB. To use a hard drive, you need to partition it.
