This is my mod of a os x theme. It's a mix of a Cheetah theme by BLUE-EXCA93 : https://www.gnome-look.org/p/1385712/ and the Leopard theme by elbullazul https://www.gnome-look.org/p/1290812/
1. I don't really like the striped background in the Cheetah theme so I mod it out. If you like the stripes in background please check out the original version. The replaced parts came from the Leopard theme.
2. Use colored icons whenever possible. Reduce usage of symbolic icons.
3. My mod of close button has different states for hover and pressed.
I used it on GNOME 3.38 without issues. But I cannot guarantee if it works on other DEs or GNOME 40.
The vista icon theme in the pic is also mine: https://www.pling.com/p/1499265/
I would like to thank both original authors for their great effort in making these themes!
