Tested Imac 21.5" running Sequoia, lovely experience on Safari Browser. Dialogs readable, no mouse or keyboard issues so far. Over 50fps
Tested MacBook Pro 2012 13" running sonoma with Safari browser, Dialog and menu text way too small to be readable even with glasses. Ocassional unresponsive mouse, resulting in 'sticking' of whatever you clicked on last being repeated.
Tested HP Envy 17", Dialog and menu text small, no keyboard input at all, tested on notecard and chat boxes. Zilch. Tried on both Chrome and Firefox.
