To get the Arduino IDE working on Apple Silicon, you have to provide a replacement compiler and uploader built for Apple Silicon, and then create a local configuration file that tells the Arduino IDE to use those updated versions. I started by following the instructions here: Apple Silicon function…

What? I just downloaded the Apple Silicon version, works fine. MacAir M3.

Have you enabled Rosetta for some other program? This is only if you don't want to have things run through Rosetta. Unless an update came out in the two weeks since I cobbled this together.

[image] jpurnell: clone the ctags repository: gh repo clone arduino/ctags Surely a "clone" is more than you need? (although perhaps it's easier to do from the cli.) avr-gcc version 9.4.0_1 is the latest. The "latest avr-gcc" has added new chips via a "packs" mechanism. Arduino has inst…

@westkf Maybe these optimizations would be better, but…not sure! I just wanted the IDE to work natively on Apple Silicon, and it hasn't seemed to be done in the four years these CPUs have been around, so this worked for me.

I didn't have Rosetta until 5 days ago and I have had this Mac with Arduino for about a year.

Thanks for sharing this information @jpurnell ! In case it will be useful to others who are interested in this subject, I'll add a couple releated links: The Arduino developers are tracking the request for distribution of native Apple Silicon builds of Ctags here: …

Is this guide current and up to date? I did not complete successfully: bad CPU etc. eg it seems the github enhancement request was almost immediately closed. is gh required? ie rather than git, which doesn’t require login/password my particular board is Arduino Uno R4 Wifi with ESP32 S3, and oth…

Thanks @jpurnell ! This guide worked perfectly on an M4 Pro mac where I don't want to install Rosetta. I did notice that some avr-gcc utils are now split out into a separate homebrew package so I just had to add a step to symlink those. Since some folks asked about using git and wondered if this guid…

macOS 27 in 2026 will drop Rosetta

I saw this too some time ago, but it turned out to be wrong info (off by 1 year). MacOS 28 is expected to drop Rosetta in September 2027. MacOS 27 coming in September 2026 will no longer run on Intel-based Macs, but when running on Apple Silicon Macs will still have Rosetta to execute programs wri…
