This should not be news to anybody who read anything on our web page or this forum in the last years: Psychtoolbox is not usable yet for research grade stimulation and data collection on Apple Silicon Macs, neither is any other toolkit. I expect to release a usable native version 3.0.20 before Christmas. It will cost money for a yearly license, like all future versions for macOS and Windows. So now would be a good time to allocate some money to buy a license before christmas.
