Go to the Partition tab, and drag the partition handle up to shrink the boot partition to the desired capacity. This allows the internal SSD partitioning scheme to be modified. As shown below, the Mac has been booted from spare480. Step #1 - boot externally, partition internal SSDīoot off the external drive*, then open Apple Disk Utility. Alternately set up the new Mac as is, then make a clone of the system volume, then boot off that clone and proceed. This can be done while retaining both the default Apple system software install and the recovery partition.įirst, make a bootable clone off an existing Mac.

How to boot and partition?Īs shipped from Apple, it is not possible to boot from the internal SSD and partition it while booted off it.Īccordingly, a separate boot drive (hard drive or SSD, anything) must be used to boot the Mac, then partition the internal SSD. There is no performance gain on an SSD by partitioning it.

In general, minimizing the risks that come from “everything in one bucket”: system, applications, user data, and so on.

Matching volume layout to another computer, or to an external backup volume-to-volume.

A need to use more than one bootable system partition.

Since each partition ( volume) has its own file system, damage or corruption or a “bad” system mean that the startup volume can be wiped clean if necessary, while not affecting data on other partitions (“my system software update screwed everything up”).

Separation of system and applications from user data.

Partitioning an SSD should be done only for clearly understood goals applicable to a particular user workflow. In general, MPG does NOT recommend partitioning a 256GB or 512GB SSD, because partitioning balkanizes capacity, and an SSD is expensive capacity. This discussion is about how to partition the internal PCIe SSD in the 2013 Mac Pro, though it applies to an iMac or any other Mac, and also to a hard drive system.

See the general discussion of Choosing PCIe Flash Drive Capacity.
