The problem is that it uses the Electron framework, and it isn?t supported on earlier versions of MacOS.

Kevin,
You may have missed one key part: large fraction of Intel Mac users cannot upgrade, because Apple removed many Intel Mac drivers from more recent macOS versions, so many R users have no choice - they cannot upgrade even if they wanted to - which why we see so many R users using macOS < 13. The question of EOL support becomes irrelevant if it is the only way to keep a perfectly good machine running. That?s why it is important for R to keep supporting macOS 11 and higher at least for the x86_64 builds (arm64 is fine so far, Apple is currently supporting all Apple Silicon Macs in the latest macOS). One could say that Apple is becoming the victim of their own hardware quality :).
Cheers,
Simon

Big Sur is no longer supported by Apple (it reached EOL in September 2023)
so you're unfortunately likely to continue to run into these sorts of
issues if you cannot upgrade your OS.

I?m neither a Posit/RStudio employee/dev nor do I use their IDEs atm, but
? while RStudio IDE requires MacOS 13+, the ?next-gen? IDE from Posit is
Positron, and it allegedly depends only on MacOS 10.15+ with universal,
intel, and arm64 binaries. See https://positron.posit.co/download.html.
I?ve played briefly with it, and while I?m an avid emacs/ess user (never
been much for RStudio IDE itself), the Positron experience is getting
closer to what I hope for. There are discussions on migrating (keyboard
shortcuts, mental assumptions, etc) from RStudio IDE to reduce the
and I believe there are few things one can do in RStudio that are not
feasible in Positron.
Good luck,
Bill

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 of
RStudio and received the same similar error you reported. When I updated
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 RStudio?
general, R and RStudio should be upgraded together.
If you still have problems with the latest release of RStudio, you should
file a big report at https://github.com/rstudio/rstudio/issues.

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

Hi,
I am not sure if this is the right forum for this query, and I
apologize
in
advance.
I recently upgraded to version R 4.5.1, and I use the RStudio
program. I
can open it without any problem, but I am experiencing crashes
whenever
I
perform any action in the program. I receive the following message:
"R Session Aborted. R encountered a fatal error. The session was
terminated. Start New Session."
Could you please recommend what I should do?
Thank you very much
