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.) -pd > On 16 Jul 2025, at 00.36, Simon Urbanek <simon.urba...@r-project.org> wrote: > > José, > > I agree that latest RStudio dropping support for a very large number of Macs > is unfortunate.
