Does Tails work on 32-bit computers?
No. Tails stopped working on 32-bit computer in Tails 3.0 (June 2017).　

Does Tails work on ARM architecture, Raspberry Pi, tablets, smartphones (mobile phones), or Apple M1?
For the moment, Tails is only available on the x86_64 architecture. The Raspberry Pi, most tablets, and most smartphones (mobile phones) are based on the ARM architecture. Tails does not work on the ARM architecture so far.

For this reason, Tails does not work on Mac models that use the Apple M1 chip.
