About Arduino IDE and Apple Silicon Macs released in November 2020
Date - 9th February 2021.
We have been getting some unpleasant support requests about using the Arduino IDE on new Apple computers based on their M1 chipsets. Well some were unpleasant, some neutral. Everyone is different.
Our short answer is - IDE may install and operate, however totally unreliable and may not work at all depending on your board type.
IDE currently runs through Apple's Rosetta 2 Intel CPU emulation. Arduino Create platform most likely will not work.
