Windows version:



Patcher changelog:
Patcher now self-checks if it has been “Run as administrator“. It prompts the user if it has not been.
A license key is now randomly auto-generated at the start, and still allows you to regenerate more [one less click for you].
The patcher just asks for the location of the executable, and no longer asks for which version you want to patch.
It works out the version of the selected *.exe and patches it accordingly.
All v4.x.x and v5.x.x releases are handled.
Tested on v4.6.9p2(x32), v5.2.3p2(x64) and v5.3.0f4(x64).
The PATCH button can only be pressed is a valid executable is found within your chosen folder.
This patcher now creates a U*i*y.exe.bak (backup of the the original exe) prior to patching. Useful for those wishing to build a release game/app with the untouched editor.


Mac Version:


f: Unity v5.6.3f1(mac).zip

p: Unity v5.6.2p4(mac).zip

  • Mèo Điên

    How about Unity 2017.1?

    • Blck Hrtzz

      Search for this “00 84 C0 74” and replace with “00 84 C0 75”. 🙂

      Sorry, i was really busy lately..
      I am going to update the tutorial in an hour or two. And will keep it updated as much as I can.

    • oOPHINOo

      Unity 2017.1 OSX isn’t changing colour with this new patch. Any idea why it would not work?

      • beBoss

        It’s not changing the colour or it’s not the pro version at all? And Are you sure that you have done everything right, mean followed the steps and have patched the right version of the software? Every patch is for specific build 🙂
