Musescore 4 and M1 based computers
Apple's M1 chip appears to work wonders for some applications - though maybe only the ones which Apple develops or approves of. I'm assuming that development of MS 4 is being done on other systems, and that no specific attempt will be made to exploit development features which Apple may provide on its new hardware systems.
Apple isn't always very helpful when it comes to software development by third party developers, but I did wonder if there are any benefits to be had by at least investigating possibilities in that direction. Presumably MS - both current and future - will run well in the Rosetta 2 environment anyway. https://support.apple.com/en-gb/HT211861
