What does this patch do?

[tillt]

It appears rather dangerous for anyone to download this patched binary and run it locally. What is extra worrying is that you are not describing what you did to get rid of that popup.

The executable shared here is the original one minus signature and one byte patched;

< 00039350: 0055 4889 e541 5741 5653 5048 8d5d e048  .UH..AWAVSPH.].H
---
> 00039350: 00c3 4889 e541 5741 5653 5048 8d5d e048  ..H..AWAVSPH.].H

... patching in a RETN and by that shortcutting the function that would check for expiration and nag us.

So from my assessment, the results are not dangerous. However, why should anyone trust or believe me? :D

I would suggest instead of distributing a patched binary, go for a live patch of the original on the users' machine. Much cleaner and more transparent - and legally most definitely a better choice.

This should do the same;

#!/usr/bin/env bash
cp /Applications/HyperSwitch.app/Contents/MacOS/HyperSwitch HyperSwitch.original
cp HyperSwitch.original HyperSwitch.unsigned
codesign --remove-signature HyperSwitch.unsigned
cp HyperSwitch.unsigned HyperSwitch.patched
printf "039351: C3" | xxd -r - HyperSwitch.patched
sudo cp HyperSwitch.patched /Applications/HyperSwitch.app/Contents/MacOS/HyperSwitch

[tillt]

....and this is how HyperDock would equally benefit;

cp /Library/PreferencePanes/HyperDock.prefpane/Contents/MacOS/HyperDock HyperDock.original
cp HyperDock.original HyperDock.unsigned
codesign --remove-signature HyperDock.unsigned
cp HyperDock.unsigned HyperDock.patched
printf "0047E9: C3" | xxd -r - HyperDock.patched
sudo cp HyperDock.patched /Library/PreferencePanes/HyperDock.prefpane/Contents/MacOS/HyperDock

You are right, and your approach is faster and safer. You can initiate a pull request, and I will merge it.

I tried to do this instead of using the .dmg in this repo, and after following tillt's first comment, when closing and re-opening the HyperSwitch application, it prompts me to enable it in accessibility settings despite already being enabled, and then doesn't actually open the application. Turning it off and on in accessibility settings also didn't work.

Trying to do @tillt 's instructions in their second comment, I get a "no directory found" for the first line. There's no entry in /Library/PreferencePanes/ for HyperSwitch.

For context, app worked fine before trying first comment instructions.

Deleting the app and reinstalling with the original unpatched seems to have resolved the issue? Time will tell.

There's no entry in /Library/PreferencePanes/ for HyperSwitch.

You did not read carefully :)

/Library/PreferencePanes/.. was for HyperDock.

For HyperSwitch, use /Applications/HyperSwitch.app/Contents/MacOS/HyperSwitch

Silly me. Thanks :)
