[R-SIG-Mac] Problems with RStudio for mac

[Simon Urbanek]

José,

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 - see 

https://cran.r-project.org/bin/macosx/big-sur-x86_64/base/

to match the last working RStudio to see if it will work for your use case.

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.

Cheers,
Simon
