It’s been a long time since Apple offered after-the-event upgrades of memory and storage, but the new Mac Pro 2023 changes that.

In response to the introduction of the Apple silicon Mac Pro, Apple has now made available SSD upgrade kits on its online store. These kits offer storage options of 2TB, 4TB, and 8TB, priced at $1,000, $1,600, and $2,800, respectively.

The upgrade kits come equipped with either two 1TB SSDs, two 2TB SSDs, or two 4TB SSDs, and are designed to replace the existing internal SSD storage in the Mac Pro.

It's important to note that these hardware upgrades are specifically compatible with the new 2023 Mac Pro models featuring Apple's M2 Ultra chips.

Apple info from the store:

“The Apple 8TB SSD Upgrade Kit for Mac Pro enables you to upgrade the internal SSD storage capacity of your Mac Pro. This kit, containing two 4TB modules, replaces the current SSD module or modules in your system. Installation required.

Note: Software reinstallation requires a second Mac running Apple Configurator 2 and a USB-C cable. Compatible with Mac Pro (2023).”
