Keyboard shortcuts for resizing windows on mac I'm looking for the Mac keyboard shortcut equivalent of &quot;windows key + left/right/top arrow&quot; to resize windows (not split view)
There is possibility to move window left or to right but I am not aware of quadrant.
If one hovers over resize button (green circle in upper left corner of window) there are different possibilities displayed depending on position and size of window. By default there should be keyboard shortcuts assigned at least to two of them:

Tile Window to Left of Screen ⌃⌘←
Tile Window to Right of Screen ⌃⌘→

These are for split view. However, there are other options, among them are:

Move Window to Left Side of Screen
Move Window to Right Side of Screen

For those one needs to assign keyboard shortcuts. System Preferences &gt; Keyboard &gt; Shortcuts &gt; App Shortucts, click on +, keep 'All applications', enter exact text as above into 'Menu Title' and assign shortcut in 'Keyboard Shortcut'. I personally have followed the path of built-in which start with ⌃⌘. For left it's ⌃⌘L and for right it's ⌃⌘R.
There is also built-in keyboard shortcut to toggle full screen: ⌃⌘F. Combined with moving window to left and right side it's covers basic needs.
There are also options Zoom and Revert to which one can assign keyboard shortcuts in similar fashion.
After assigning shortcuts and while hovering over resize button my machine displays following (interesting to note that full screen toggle shortcut is not displayed)

For more elaborate window arrangements I use paid app Magnet.
