Hi all,
Obviously, the answer to this depends upon just what software you use, and I'll list the things that Sonoma broke for me, but first I'll list something that anyone may experience. (I'm currently running macOS 14.0 and have upgraded and recompiled all of my software.)
(1) I often switch between two or more user accounts, and there are several options for performing this switch: (a) one can open the Lock Screen, then switch usernames there, (b) one can click on the username in the menu bar and switch usernames there, or (c) one can open the Control Center, click on the users's icon, and select a different user (if setup in System Settings...). For me the (a) and (b) methods work fine, but (c) on the other hand caused a serious problem.
When I tried (c) and clicked on the users's icon and selected a different user, the new user's login screen appeared with the username already filled in but the password box was empty. Before I could enter the password (I use fairly long passwords but I'm also relatively fast at typing), the login screen went black for about a second then reappeared with both the username and password boxes empty. Before I could now type in both the username and password, the login screen again went black and reappeared after erasing whatever I had typed. This behavior continued repeating, not allowing me to login to either the new user nor the original user. I was essentially locked out of the Apple Silicon MBP. [I took iPhone videos of this behavior both times that I tried (c).]
I then SSH logged into the machine remotely and killed the WindowServer daemon, but this didn't fix the issue. Eventually I had to "shutdown" the MBP from the SSH login to recover. After the reboot, I tested this (c) issue and it was repeatable for me (the second time without any of my software running, just a freshly rebooted system and a new login -- no other software running).
So, in a nutshell, you might experience trouble when using the Control Center to switch users. (It is interesting to me that all three methods must not be running the same code, as (a) and (b) work properly but (c) fails badly.)
(2) I have had the occasional Bluetooth troubles. In particular, my Magic Trackpad will spontaneously disconnect while leaving my Magic Keyboard still connected -- thus Bluetooth is still working, just that the Trackpad disconnects (the Trackpad's battery level was 71% by the way).
Below are problems specific to my usage:
(3) There is a new minor problem with Ghostscript that causes Gimp not to use Ghostscript properly and crashes Gimp. I've rebuilt Ghostscript, and used three alternative versions of Gimp, but the problem persists.
(4) There is an "xfig" font problem that "fontconfig" doesn't correct. You might consider this an X11 problem with fonts under Sonoma.
(5) There is a new issue with Gnuplot running properly from within Sage, Maxima, or standalone.
(6) I've even had a new failure of one of my long bash scripts that I had to rewrite part of the bash script to eliminate this error.
(7) The "pdfcpu" utility works most of the time (extracting, merging pages from much larger PDFs), but I have found a PDF that causes a repeatable crash of pdfcpu running on the Apple Silicon MBP. However, executing pdfcpu from an Intel MBP on the same PDF works properly and doesn't crash, so this is an Apple Silicon pdfcpu problem that doesn't occur on Intel.
In summary, Sonoma has been quite buggy for my usage, more so than even Ventura was initially.
