I've used Spectacle with the defaults, for years. It's not actively developed but still works. There are actively-maintained alternatives, but since it has zero times done anything weird or glitchy for me, even with multiple monitors, I've not switched yet.

"brew install spectacle", start it, give it accessibility permissions it needs in the Settings panel, set to start at login (check a checkbox in Spectacle's settings panel). Forget about it until you set up a new Mac.

cmd+option+up/down/left/right for half-screen tile. Cmd+option+F for the equivalent of maximizing a window in Windows (not Mac-style fullscreen). Cmd+ctrl+left/right for upper-left and upper-right quarter tiles. Add shift to make it lower-quarter on that side. That's it. Was all available to me instantly via muscle memory inside a month, don't even think about it now. It's how I do nearly all my window placement/resizing.

Spectacle is a must have IMO.

I set mine up to be Shift+Ctrl+(QWE/ASD/ZXC).. where Q/E/Z/C are for the corners, A/D left and right halves, W/X for top and bottom halves, then S in the middle for full screen. The mnemonic of the "box" formed by those keys on the keyboard is easier for me to remember.

I used Spectable as well. The newer version is called Rectangle.

I've used Moom for years now - https://apps.apple.com/us/app/moom/id419330170?mt=12 - it has all the things, menu access, window snapping, short cuts, custom configuration, and saved layouts

You can add keyboard shortcuts to do that in settings if you really want it. It still does that. If you run apps in full screen mode it gives you a rudimentary tiling workspace on each desktop with a tiled app on it.

Just long press on the green button on the window for a tiling menu.

It doesn’t have a keyboard shortcut by default, but you can bind 'Move Window to the Left Side of the Screen' and 'Move Window to the Right Side of the Screen' in Keyboard > Shortcuts > App Shortcuts.

another thing to note is that you can add shortcuts to any application as long as it has a menu title... you just have to type the menu item exactly. this also works to effectively remove shortcuts from apps that hijack something that you use elsewhere and don't want available ever. you have to set it to something like control option command shift F15 or something that you'd never use.

Check out the Mac app "Magnet" on the app store.
