Unity3D File Software Will Launch

I tried to debug the application via lldb and set a break point to the ProcessLicense but it was never hit.

New versions (I think after 2017) of Unity3D editor required UnityHub application in order to open or create projects.

After a day of not so hard investigation and one coffee cup Ive got this.

I am on Linux half of my life, and while in general its cool it is also sometimes painful, not this time thought.

In few words its squashfs file system with binary that mounts that file system and start AppRun script there.

This will cause the runtime to create a new directory called squashfs-root, containing the contents of the AppImages AppDir specification.

Indeed, further investigation points that this is an electron app.

According to documentation, business logic should be somewhere in app folder or in app.asar archive.

Asar by the way is something like tar for JavaScript.

To work with asar files we need to install asar package for node, simple stuff.

Unity3D File License Will Fail

Interesting enough to comment this stuff out and return true, we all know that signature for our new hacked license will fail, if we allow proper check.

Indeed well, valid and activated is our properties for search.

Now we can ask for personal license, add features to it;-) and your are good to go.

It seems, internally, development teem moving out license check to UnityHub, and during runtime Unity app through IPC communicates with UnityHub and blah, blah, blah.

This is in theory, but currently there are two places where license check performs.

Dont know why. maybe IPC not implemented on Linux, or managers dont want to fully delete this functionality, or maybe clients dont want to install UnityHub.

Long story short - Unity not running with fixed UnityHub Lets disassemble it Im interested in string SignatureValue.

And it turns out that LicensingLegacy::LicenseInfo::ProcessLicense is our function, Ive highlighted our if else statement.

BTW, when you building app for iOS from Linux - nothing happens.

Literally - filling like you press mock button - no reaction.

Even in logs No. Reaction.

Ughhh. Lets look what is happening from processor point of view.

After a bit of dancing with tambourine Ive found interesting place.

Before calling gtk method to show save panel unity checks which platform you are running on, and compare it with some value.

At this time I was tired enough to just remove that check without going deeper.

These steps work on 2019.3.10 on Windows but however not on macOS.
