How to upgrade Mac Pro storage with Apple's new Mac Pro SSD Kit

By Andrew O'Hara

Apple's new Mac Pro isn't stuck with what you buy at initial purchase. A SSD upgrade kit from the company can quickly add one to eight terabytes of storage to your professional workstation by following these steps.

Mac Pro owners now have three options for more storage on their device -- they can choose an external storage drive such that connects over USB or Thunderbolt 3, they can choose an internal option such as the Promise Pegasus R4i or OWC Accelsior 4M2, or they can upgrade the stock internal SSD thanks to newly released upgrade kits from Apple.

Use cases determine which of those solutions is best, but there are benefits to upgrading the primary drive. Many apps, scratch disks, and other components are stored on the primary drive by default and sometimes users may need access to all of the PCIe slots. Whatever the reason, upgrading the primary drive is now possible.

As Apple's machines have become more complicated -- and more secure -- what used to be a near-trivial procedure is now a multi-step, labor-intensive process. It isn't as easy as swapping out a drive sled and restoring from a backup. Rather, it now involves not just more work to swap the parts, but a second Mac to aid in the restore.

That said, the process is entirely manageable. We will walk you through the process of removing the old module or modules, installing the new ones, restoring the T2 firmware, and reinstalling macOS before finally moving your data back.

Assuming you've picked up Apple's new upgrade kit, here is how to install them on your Mac Pro.

Before we start

Before you begin the task of upgrading the SSD in your Mac Pro (2019) there are a few things to touch on.

Once done, your old SSD module will be unusable. Apple uses its own proprietary SSD so it won't fit in any enclosure and once the new SSD has the T2 firmware restored, the old SSD's data will be inaccessible.

And speaking of data, if you are planning to restore from the previous drive, it is important to ensure you have a recent backup that you are able to use.

Before you can use the Mac, we will need to restore the T2 chip's firmware to pair with the new SSDs.

It may seem daunting, but it not far off from a normal SSD replacement sans the necessity for a second Mac. The process is relatively quick all things considered and it is a huge step forward for swapping storge on T2-enabled devices.
