R and RStudio on Mac: Compatibility and performance considerations

R and RStudio both support Macs with Intel processors as well as those with Apple Silicon chips (M1 and M2). The official R project provides native ARM builds that fully leverage Apple Silicon, resulting in improved performance compared to running Intel versions through Rosetta 2 emulation.

User reports and benchmarks generally show faster startup times and more efficient memory usage when running the native ARM versions of R on Apple Silicon Macs. RStudio also offers a native version optimized for Apple Silicon, which should be your choice if you have an M1 or M2 Mac to maximize compatibility and speed.

Performance tips for Mac users include closing unnecessary applications to free RAM and monitoring CPU usage via Activity Monitor when running intensive R scripts. Using the native ARM versions reduces overhead, but some R packages may still require compilation or run slower if not yet fully optimized for ARM architecture.

Known limitations on macOS include occasional graphical glitches in RStudio related to hardware acceleration and minor delays in package installation when using source packages that require compilation tools. macOS security features can sometimes block RStudio components initially, requiring manual permission adjustments in System Preferences under Security & Privacy.

To ensure optimal performance and compatibility, always download the latest R and RStudio releases from official sources, selecting ARM builds for Apple Silicon Macs and Intel builds for older Macs. Regularly updating macOS also helps maintain stability and compatibility with these tools.
