There is a lot of noise about the changes in macOS Big Sur starting to pave the way to a touchscreen Mac.
Thought I would give it a try so I created a reasonable working simulation by using JumpDesktop.
MacBook Pro running BigSur
iPad Pro with Trackpad running JumpDesktop
I use JumpDesktop to remotely connect to the Mac and then switched the mouse simulation to the MacBook Pro in JumpDesktop from “Trackpad” to “Direct Touch”.
The new Big Sur desktop is definitely easier, but not perfect, for finger touches instead of a mouse or trackpad. The window open/close stoplights are still hard to hit.
I made a quick screen recording and posted it: https://youtu.be/3EhdvVcRMXc
(Probably can do the same in other remote control apps, but I use JD as the most versatile)
