PTB beta update Psychtoolbox 3.0.20.1 "Appletizer SP1" ### Compatibility changes wrt. Psychtoolbox 3.0.20.0: - None ### Highlights: - None ## macOS: - Psychtoolbox was built and tested against native Matlab R2024b and against native Octave 9.3 from HomeBrew, on macOS 13.7.1 Ventura for Intel Macs, and on macOS 14.5 Sonoma for Apple Silicon Macs. - Try to execute same code path on Apple Silicon macOS, regardless if running under native Matlab/Octave for Apple Silicon ARM, or running under Intel Matlab/Octave via Rosetta2 emulation. Our license management aggregate stats tell us that a non-trivial fraction of users still use Matlab for Intel Macs via Rosetta2 emulation on Apple Silicon, instead of the recommended native Matlab/Octave for Apple Silicon. This would cause PTB to misbehave, as it would think it runs on an Intel Mac and acts accordingly, instead of adapting to the special snowflake that is macOS on Apple Silicon. This will especially cause trouble with visual stimulation timing and some visual stimulus presentation. Note that this fix tries to fix this, but Psychtoolbox is not and will not be tested for proper compatibility and quality when running under Matlab/Octave for Intel via Rosetta2 on Apple Silicon! Switching to native Matlab/Octave for Apple Silicon / ARM is strongly recommended. - Audio demos and tests: Request standard latency instead of larger latency on Apple Silicon. The lose latency requirement was only meant to accomodate RaspberryPi's, not Apple Silicon.
