Installation on Big Sur fails obspy-runtests

Brand-new macbook pro - installed python3 using Homebrew, then followed the instructions here verbatim

except that I specified python=3.8 instead of python=3.7 when creating the environment.

obspy-runtests produces 86 errors, most having to do with matplotlib, but some also with UTCdatetime. The report is here.

https://tests.obspy.org/114160/#1

Attempts to install by pinning to earlier versions of matplotlib have been unsuccessful. Any suggestions would be most welcome!

Hi Lara, welcome to the forum!

I know that the UTCDateTime tests are fixed in the master branch and can be ignored without hesitation.
I think the same holds true for the matplotlib errors.
