Hi,
Welcome to Pix4D Community!
Have you tried to use Bootcamp in your Mac silicon m1? Unfortunately, Mac Systems using parallel is not supported, as they use a virtual Operating System which may give problems with the display of the rayCloud and may fail to process.
Otherwise, we have a stable PIX4Dmapper version for Mac OS X 10.11 - El Capitan or 10.12 - Sierra that you could explore. Please for more information, you could refer to the following articles:
macOS / Windows XP / Linux / Remote access / Parallel processing
I hope you find this information useful. Don’t hesitate to contact us if you still have questions or concerns.
Have a nice day,
Best regards
