MacOS cursor with the Mickey hand. Especially now those monsters at Apple took it out from actual MacOS 😭

These are also available on KDE when you click the get more button or whatever it's called (I'm not at home) in System Settings.
A preview of a few but open the website, they're animated. Plus there's multiple styles and dark modes.

Don't forget that great video that goes with those cursors: https://www.youtube.com/watch?v=YThelfB2fvg

The only one I change is the finger pointer to be the middle finger instead of the index finger.
I just checked, and it is apparently called "Default".
I'm using that as well. I like it, it was very easy to install and get working.
Damn, I need to get that one it seems popular!
Breeze white, left on laptops. I use the track pad left-handed. Always freaks people out when the cursor is reversed and I'm used to it now.
Also, if you're trying to click on the first half of a letter to highlight (and the cursor doesn't switch to the beam), I find it easier when you can see more of the letter.
Banana cursor
I always use Breeze Dark (even tho I don't use Plasma)
Breeze but the white one
the default x11 one (tiny black cursor)
DMZ-Black. It's one of the cursor themes provided by default by Linux Mint. I see no reason to change.
The default pop!_os one :3
I'm using one of the Catppuccin ones right now. It comes in a lot of colors, so there's always one that looks good with the theme I'm using.
