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

Mon Jul 21 16:53:00 CEST 2025

At least for a while, it seems that only support has been dropped; the RStudio binaries still work under MacOS 12. (Or, I haven't managed to break anything yet.)

(It is not strictly an Intel/ARM issue: Some Intel Macs do go beyond OS 13, MB Air from 2019 stops at Sonoma, but I think Intel MBs from that year runs Sequoia. Both my iMacs from 2015 are off support but still very capable machines.)

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).
