Storage vendor OWC warns of an issue with Apple’s latest macOS and SSD firmware updates.

macOS Monterey Install Requirements for OWC Aura Pro SSDs
In later 2019 iterations of macOS … Apple’s install would not always update the firmware of systems using 3rd-party NVMe storage—even if the operating system itself was installed properly.

Unlike macOS 11 (“Big Sur”), which required no firmware update, Monterey will not successfully install on a machine with an OWC SSD installed if the firmware is older than the fall-2019 macOS 10.15.x Catalina iteration. This impact will be noticed when attempting to install or update an OWC Aura N2 or OWC Aura Pro X2 SSD.

Any users who might be encountering this issue should update their system firmware to the latest (4xx. before attempting to install macOS 12.x on their OWC Aura N2 or OWC Aura Pro X2 SSD.

Howard Oakley talks about installing macOS Monterey on an external drive for an M1 Mac.

Creating a bootable external disk with an M1 Pro in Monterey
In the early days of the original M1 Macs and versions of Big Sur prior to 11.4, installing and setting up a bootable copy of macOS on an external disk was unreliable and often failed. I’m therefore surprised that users still contact me claiming that they’ve had problems with more recent versions of macOS, including Monterey, and with the new M1 Pro and Max models. As a sequel to my article about the basic principles of using an M1 Mac, this explains how to set up a bootable external disk in Monterey on an M1 Pro.

Mr. Macintosh documents an unexpected twist in Apple’s Mac recovery system.

Big Sur 11.6.1 Update Upgrades Recovery to Monterey on M1
So what is the deal with this situation? We have a few possibilities.

  1. This is a bug or mistake on Apple’s part. This is unexpected behavior that we have not seen before.
  2. There is a technical reason behind the change.
  3. Apple wants users to upgrade to Monterey when reinstalling macOS.

I’m not pointing in any one direction because I don’t know why this is happening. I’ve submitted a ticket to Apple Enterprise Support to find out. I will update you when I hear back.

Phil Cruse is tracking macOS printing problems:

Printing and Other Problems in macOS, especially ‘Mojave’, ‘Catalina’, ‘Big Sur’ and, possibly, ‘Monterey’
Over the past few years, especially since the release of Apple’s macOS 10.14 ‘Mojave’ and later versions, several colour problems were reported by our customers and on internet photographic fora. We explain a few of them here, along with possible fixes or work-arounds. There’s also some advice on Mac ‘housekeeping’ and why not to rush in and upgrade to the latest version.
