Tips & Guides Have you tried even smaller window corner radius?
This trick is nice to try how Tahoe (or GG) would look with corner radii of previous releases. But somehow only now I had idea to try zero. It does not work, but value of 1 does.
It is so sharp. It gives strange feelings. At least temporarily, for fun, it is a nice experience to try.
In case you are not familiar with this key at all — you control it from the command line. In Terminal:
For customizing (last number is the radius value):
defaults write -g NSConvolutionOverride1 -float 1
For removing customization:
defaults delete -g NSConvolutionOverride1
Apps apply the new radius after relaunching them. Not all apps work with this (e.g. Chrome does not).
BONUS 1: Try setting value to 0.1 — it gives a strange thicker rendering for border (at least on Tahoe, didn’t test on GG).
BONUS 2: Using large values has no practical value, but for your enjoyment I have attached screenshots with some abstract window art achieved by using 100 and 300 values. :)
EDIT (thanks to u/22Megabits idea): BONUS 0: Setting negative value (like -1) clamps it to zero and removes rounding completely, similar to 0.1 (while setting 0 directly is ignored). Border rendering gets altered a little bit comparing to the default, but not as radical as with 0.1.
