Partition scheme prevents the external drive from being bootable on a Power PC GPT, APM, and MBR (to enable use as a bootable drive for PCs). In the Partition pane that enables you to specify a partition scheme including Thankfully, as of Mac OS X 10.4.3, Disk Utility has included an Options button
To confuse matters even more, when you connect and partition an externalĭrive, the Apple Disk Utility uses the APM partition scheme by default. Well as Intel Macs, GPT needs to support a level of backward compatibility for Because EFI and GPT are designed for use in non-Apple PCs as The differences between the two relate specifically to how theįirst blocks of data on the physical disk (which describe the partitions on theĭisk) are laid out.

Partitioning scheme is somewhat irrelevant. Thus, they do not contain the partition map, so the OS X disk image because disk images are generally an image of a partition, notĪn entire physical disk. The part about the ExFAT setting I understand, it’s the partition scheme setting I’m not clear on.This doesn’t directly relate to the problem of creating a universal Mac Apple Partition Map: Choose this option for compatibility with old PowerPC-based Mac computers.”.Master Boot Record: Choose this option for compatibility with all Microsoft Windows-based computers.Some newer Microsoft Windows-based computers can also use this scheme. GUID Partition Map: Choose this option for all Intel-based and Apple silicon Mac computers.“Disk utility supports the following schemes. If you click on the link “choose a partition scheme”, the linked page says: despite the fact the instructions are for formatting an external drive for use between Mac OS and Windows. the instructions just say “choose a partition scheme”. The default seems to be set at GUID Partition Map, but Apple isn’t clear if that or the other choice, Master Boot Record is the one I need to choose. you have to chose one when you are formatting the disk. The question is what “Partition Scheme” do I use?.

this is so I can share large collections of files between my Windows based computers and my MacBook. Sorry, I left out the word “external” (hard drive) when I wrote that. Thank you in advance for any information you may have on this topic. I haven’t formatted a Hard Drive for PC compatibility in a while, but I think it usually was Master Boot Record, but I definitely don’t recall mention of a 2TB limit.Īt the moment, the drive I am formatting is 2TB, so it probably won’t be an issue, but I’m asking this in advance as I wish to use a larger capacity drive in the near future. I decided to look that up and again it’s not really clear, since some either just repeat what Apple has written or they go into the pros and cons of Master Boot Record vs GUID Partition Map.īut two sources say basically that Master Boot Record is the choice for MS-DOS (FAT) or ExFAT, and Drives cannot exceed 2TB” In Apple’s “Disk Utility User Guide”, the Section “Partition schemes available in Disk Utility on Mac” is rather ambiguous as to whether “Master Boot Record” or “GUID Partition Map” is the appropriate choice for formatting a Hard Drive for use between a Mac and a PC, since the wording makes it seem that both can be used by Mac and “Some newer Microsoft Windows-based computers”
