This gives us no info... please be more specific and provide logs

Forge only supports the way the Vanilla launcher works, no special support for other launchers. It's unfortunate that pack devs get caught up in this, but if you're looking for a way to distribute packs we usually recommend CurseForge as it's where most mod devs upload the mods themselves.

Why is this needed? This sounds like spyware

I think this is done in Eclipse's Preferences in the Java section? I don't use Eclipse personally.

You might have it but it's not what your IDE is using to run the project

It looks like Gradle is trying to use Java 16, this isn't going to work. Set JAVA_HOME to the JDK8 root and try again

Move your mod workspace out of .minecraft, there's no reason to put it there and it might complicate file permissions

I think Forge for 1.17.1 should work, but I don't have an M1 Mac to test with

At this time Optifine has a monopoly on shaders. Sorry I came on a bit strong, the more people ask this question the more annoying it gets that they seem to think open-source Forge needs to change to fit closed-source Optifine

Not our problem. An open-source project and a closed-source project are incompatible, why do you assume it is the open-source project's responsibility to become compatible with code they are not allowed to see?

Is this the error? GLFW error before init: [0x10008]Cocoa: Failed to find service port for display If so you're out of luck for older versions as Apple decided to say "To hell with backwards compatibility" with their new stuff so 1.16.5 and previous aren't compatible.

Are you on an M1 Mac?

1.16.5 is not compatible with Java 16, if you still have Java 8 installed you can use it by invoking the full path to the java executable instead of just invoking "java" and letting your computer pick which one to use
