ROOT stopped working, suddenly

My ROOT built used to work fine until two days ago. Suddenly, it’s now throwing these errors. I tried to download the most recent version and build it and am getting errors too (I made a separate post about that).

Here’s the error that I get. Any clues as to what went wrong?

Please read tips for efficient and successful posting and posting code

ROOT Version: 6.26
Platform: Mac OS X Monterey
Compiler: clang version 13.0


This is due to a macOS upgrade; ROOT is currently still way to sensitive to the (often massive…) changes introduced by those macOS upgrades, even if it’s between point releases.
