Error when installing R on MACOS Monterey 12.7.2 - using latest install version

Any insight into my issue would be really appreciated.
I am running MACOS Monterey 12.7.2 based on model model16,2. When I try to install R, I get an error message- R 4.3.2 ARM64 cannot be installed on this computer.
Here is what I found in the Log file

Please clarify what you mean by "model model16,2". Is this an iMac?

Have you tried the version of R for older Intel Macs, R-4.3.2-x86_64.pkg? R-4.3.2-arm64.pkg is only for Macs with the Apple silicon chip.

Yes I am on a iMAC. i was able to figure this issue out. even though i am on the current MACOS 12.7, i do have an older MAC. i used the MAC legacy R install versus using the one indicated for OS 12.7. Same applied for Rstudio where i needed the older version. second issue is that Rstudio install does not automatically install in the apps directory. you need to move the install package first then install. if do not move the install field and just install, Studio will not install correctly as there will be no drop downs in the menus such as 'File' and you need to force quit the app.

I wonder if your decision to use older versions of R and RStudio will create problems later.

Why did you install R 4.2.3, which is for macOS 10.14 (High Sierra) or higher, rather than R 4.3.2 for macOS 11 (Big Sur) or higher? The latter should work as long as you choose the installer for Intel chips, not Apple silicon.

Which older version of RStudio Desktop did you install? Version 2023.12.0+369 should work with Big Sur or higher, which includes Monterey.
