Hello everyone,
the Tahoe update went surprisingly smoothly—the schwupp-dicity is impressive, and the essential apps and functions continue to run without any problems. The design has some good and some not-so-good aspects (border radius), but I don't want to complain.

However, there is one bug (?) that is very annoying, and I wanted to ask if anyone has any smart ideas about it:

Apple Mail formats a considerable number of my emails partially or completely in “Arial Black” – and only the “unformatted” part of the email content... (Text that has been formatted by the sender with a different font or bold/italic/underlined is displayed correctly for me).

Changes in the mail settings under “Font and Color” have no effect (on incoming emails).
Since I deleted “~/Library/Containers/com.apple.mail,” no new “Arial Black” emails have arrived (but that could be a coincidence), but unfortunately the old misformatted emails remain as they were.
Deleting the system font caches (+ restart) didn't help either.
The font used (Arial Black) is located in the “System / Library / Fonts / Supplemental” folder and cannot be deleted / renamed (for testing purposes) – not even as root (...and I don't want to go any further at the moment).

I'm grateful for every contribution that helps further. :)
