This is not needed anymore with game-ci/unity-builder@v4. If you still need this for some reason, let me know and I can resurrect this I have resurrected it after some people asked for it.
You decided to add a CI/CD pipeline to your Unity Project using GameCI.
What's the 1st step? Activating Unity! Easy, right?
You generate the alf file after creating the github action. You carry on with the list and head to https://license.unity3d.com/manual, all set to create that ulf file.
Plot Twist
But wait a second. There is an error - "Unity no longer supports manual activation of Personal licenses."
You disregard the message and upload the alf file.
But, the option to generate an ulf for a personal license? Poof, it's vanished. Instead, Unity asks us to type in a serial number.
Time for a bit of trickery
Right-click and inspect the serial number box.
Find the <div class="option option-personal clear" style="display: none;"> code;
And delete "display: none;".
Boom! The Unity Personal Edition option reappears. 🎉
Hopefully, before this hack stops working, GameCI will have an official workaround :)
