Snapping windows to sides(and to quarter of the screen), splitting windows across multiple monitors are two biggest offenders imo. Microsoft dealt with them perfectly. Also, using shortcuts to move windows between different monitors, and maximizing windows.
Also Mac is constantly running slow for me, to the point where I need to reboot it every couple of days. Opening a new tab in chrome can take seconds.
I've never had problems like this on windows/Linux.
Company policy mostly forbids installing third party software, but if there is one that's trustworthy, I can probably install it.
Regarding the slowness try weeding out third-party background apps and using Safari.
(Un)fortunately I can't be using Safari, company requires chrome.
Also, I am charging Mac from the right side, because that apparently matters :-)))
(I have Mac pro 2017 or 2018 with 16gb ram)
Primarily, I can never seem to predict what pressing win+Left will actually do. Sometimes it moves the window to the left half. Other times it moves to the right half. And some other times it does nothing until I press win+right first. Overall I think it’s a terrible window management system. Sure MacOS has nothing built in but it takes about 5-10 mins to install and configure a much better system.
I don't think that's new, early versions of OS/X were riddled with problems. I remember my first iMac would kernel panic every time I unplugged a USB stick, even after ejecting it.
