At least for a while, it seems that only support has been dropped; the
RStudio binaries still work under MacOS 12. (Or, I haven't managed to break
anything yet.)
(It is not strictly an Intel/ARM issue: Some Intel Macs do go beyond OS
13, MB Air from 2019 stops at Sonoma, but I think Intel MBs from that year
runs Sequoia. Both my iMacs from 2015 are off support but still very
capable machines.)

Jos?,
I agree that latest RStudio dropping support for a very large number of
Macs is unfortunate. It may be worth raising it with Posit - we have very
deliberately not increased the macOS version requirement of R binaries,
because it would affect way too may R users based on the estimates from
weblogs (as Intel Mac owners simply cannot upgrade).
That said, in the meantime you can install any older R version as well -
Of course, for regular work you can switch to the Mac GUI which always
supports the same macOS version as R, or any of the other GUI alternatives
that don?t embed R.

Thanks Kevin and Roy,
I work with two old Macs with the BigSur operating system (one at home
one at school) and I can't upgrade, which prevents me from having the
newest version of RStudio because it doesn't meet the requirements.
I wanted to install the caretSDM package, on the Mac at home I had
4.3.3 and the package recommended me to use a newer version of R and I
upgraded to version 4.5.1. In the case of the faculty Mac I am using
version R.4.4.0 and I have no problem with the caretSDM package.
From my ignorance I dare to say that there is a package that is
the conflict with R version 4.5.1.
Best regards,

Hi Jos?
fwiw, I tried R 4.5.1 on my macmini (15.5, Intel) with an old version
RStudio and received the same similar error you reported. When I
to the latest RStudio (Version 2025.05.1+513 (2025.05.1+513)) my quick
(matrix multiplication) worked without error.
cheers, roy

Did you already try installing the latest available release of
general, R and RStudio should be upgraded together.
If you still have problems with the latest release of RStudio, you
Thank you Jeff for your suggestions, I will keep them in mind.

R is maintained by the volunteer R Core group, while RStudio is
by Posit. You may get more thorough help with RStudio if you ask at
Posit forum.
That said, as a rule the RStudio team has to play "catch-up" when R
upgraded by R Core. You may be running an older version of RStudio
does not know how to deal with R 4.5.1. Check for a newer version of
RStudio, or try uninstalling R 4.5.1 and re-installing an older
R... or try using R with a different text editor (there are a lot of
RStudio is a fine option, but it is not the only way to use R.
