I haven't made the switch yet as my old Lenovo is still hanging on. Would you mind expanding on your gripes with MacOS, in particular the comment about responsiveness?
For me it is the little things. Like switching windows. Mac feels half a second slower then Linux and that delay make it feel less responsive. Opening up the terminal can iterm2 is another one. For me these things just adds up. I want my OS to get out of my way when I want to get work done.
I have turned off the genie effect and perhaps other animations, but my Ubuntu on my Lenovo still feels faster than the Mac.
