 > > Ah I see. When you said upstream I didn't realize you meant "the
 current version on PyPI/GitHub". I upgraded to ipython 8.29.0, the latest
 release, and indeed I can now use the `MacOSX` backend. However,
 rebuilding the matplotlib font cache every time I issue `ipython --pylab`
 is still happening.

 rebuilding; I haven't seen that myself I think but might not have been
 paying attention...

 Regarding the font cache. A bit of Googling suggests that removing the
 cache and then rebuilding it once, should/could resolve the issue. Most
 likely the cache is in {{{~/.matplotlib}}} and assuming you have made no
 specific changes manually there you should be able to just remove the
 directory. To make sure where {{{matplotlib}}} is looking for the cache
 you can do:
 {{{
 import matplotlib as mpl
 print(mpl.get_cachedir())
 }}}
