The developer notes for macOS Monterey 12.3 beta contains details of new features and also deprecations.
Python 2.7 was removed from macOS in this update. Developers should use Python 3 or an alternative language instead. (39795874)
I moved to Python 3.x a while back (I use conda python) but if you are relying on system python and are still using version 2.7 this sounds like time to move.
General Issues with Monterey
After a period of open beta testing MacOS 12 Monterey is here.
If you want an overview of Monterey I'd recommend the excellent arstechnica review.
Monterey supports both Intel and Apple Silicon Macs, the list of supported Macs:
- Early 2015 and later MacBook Air
- Early 2015 and later MacBook Pro
- Early 2016 and later MacBook
- Late 2015 and later iMac
- Late 2014 and later Mac mini
- 2017 and later iMac Pro
- Late 2013 and later Mac Pro
You can find out your Mac model by tapping on the Apple icon in the menu bar and going to About This Mac. Unsupported Macs will continue to get security updates for Big Sur (for 2 years) and Catalina (this is last year?).
I've contacted all developers I know and their responses to date are shown below, first impressions are this is a relatively benign update.
Absoft Absoft Pro Fortran 2022 For macOS Fully compatible with macOS Monterey (12.0)
alvaDesc We have tested our tools on Monterey and they work fine.
APE New version uploaded for Monterey
Avogadro no issues reported
BBEdit version 14.0.2 is recommended with macOS Monterey.
ChemAxon Most of our software in general requires Java, so as long as the appropriate Java version is installed, there should be no problem.
ChemDraw no issues with initial tests
ChemDoodle ChemDoodle 2D and ChemDoodle 3D are both fully supported on macOS 12 Monterey with no known issues
Chirys View no issues with initial tests
Conquest and Mercury from CCDC The full CSD software portfolio, including Mercury, ConQuest, Mogul, GOLD, CSD-CrossMiner, the CSD Python API, and other components, is expected to be fully supported on macOS 12 Monterey from the next major release - the 2021.3 CSD Release which is due in December 2021. We don't anticipate any significant problems with Monterey based on our initial checks, but we are running more extensive platform tests now to confirm that."
Cresset testing underway
CrystalMaker supports all from macOS 10.12 "Sierra" to 12.x "Monterey"
We are also very-pleased to announce the immediate availability of CrystalMaker 10.6 for Mac, SingleCrystal 4.1 and CrystalDiffract 10.9 for Apple Silicon: these are Universal Binaries and provide 100% native performance on the new Apple Silicon Macs, as well as 100% native performance on Intel.
DataWarrior Seems to be working fine.
DEVONagent fine under Big Sur on Intel, not tested on Apple Silicon.
DEVONthink fine under Big Sur on Intel, not tested on Apple Silicon.
Elemental Fine under Monterey and on Apple Silicon
Gaussaian We do not currently have an official report for support under macOS Monterey 12. We will be working on this over this week and list it on our website as a supported release if our tests pass successfully. I should also mentioned that we have not received any reports from users about issues with macOS Monterey. We have also run GaussView 6.1.1 and the Gaussian 16 rev. C.01 utilities on beta releases of macOS Monterey prior to the official release. Thus, we do not anticipate any issues with GaussView 6.1.1 and Gaussian 16 rev. C.01 (64-bit) under macOS Monterey on Macs equipped with Intel CPUs.
gFortran Standalone installer of GCC 11.2, including gfortran 11.2, for macOS Monterey (macOS 12). This is for machines with Intel processor.

Sketch the latest Sketch release is fully compatible with Apple’s new operating system. And of course, when Universal Control lands in a future macOS Monterey update, it’ll work perfectly with Sketch. Plus, if you’ve recently upgraded to a brand new MacBook Pro, Sketch already supports the new M1 Pro and M1 Max chips. So you can work faster than ever with all the power of your new machine
Spartan Intel or M1 chip, 4 GB RAM or higher, OS 10.12 (Sierra) through OS 12.X (Monterey), 128 GB disk space or higher
Stardrop a quick update regarding StarDrop 7.1's performance on the new Mac Monterey OS. Our test engineer has begun the process of running our standard testing procedures and noted that there are a couple of very minor cosmetic issues in the GUI but no show-stoppers in terms of performance or functionality. The couple of issues identified are flagged up to be sorted for StarDrop 7.2, which will release in Q1-2022.
