Hi,
I am trying to do a simple calculation within RStudio and I am getting the above message. My macOS is Monterey v12.7.6 with an Intel processor. I downloaded and installed R from CRAN [For older Intel Macs:
R-4.5.0-x86_64.pkg]. I then found the RStudio version for my OS [RStudio version 2024.09.1+394, RStudio Desktop Releases on Unsupported Versions of MacOS]. I uninstalled after getting the session aborted error last night. I reinstalled just now and I am still getting the same error.

I am wondering if I have the wrong R version installed since the installed version is for Big Sur from CRAN.

Any help would be greatly appreciated.

I just encountered the same problem with same versions, every time I use a R console command or try to update packages the RStudio session crashes. I tried a few earlier versions of RStudio with R 4.5, same problem, and then an earlier R version 4.4.3 (2025-02-28) with RStudio 2024.09.1+394, which seems to have worked.

It appears to be a problem with R 4.5 and pre-MacOS 13 Intel Mac versions of RStudio.

Same issues with 4.5.0 but on Apple Silicon chip, running MacOS Sonoma 14.7.5 running on Apple M2 Max.
I reverted to 4.4.3 and it seems to work.

Thank you so much for the solution! Everything works now. I did not do an R update on my personal computer since 2022 so I really appreciate the help.
