Hi,
We recently published a first version of our large project for Mac. It's Universal App for Intel and native code for Apple M1 chip. The product was compiled with fpc 3.2.1 fixes and Lazarus Trunk (2.1.0).
The program works very stable, no crashes, even on a new M1-powered Macs.
I had to use the latest fpc version to get a native support for M1 aarch64/darwin compiler, however fpc works flawless with O2 optimizations.
I'm very happy and grateful to all FPC and Lazarus teams for their great development tools!
