NoSuchMethod Error OptiFine

[Wabooe]

Hi.

 

I know this error is already in the FAQ's, but all it says is to install Optifine after Forge, which I did. 

 

Here's the crash log:

I think it's just because I'm using OS X, but any advice appreciated.  

Optifine creates a new installation in my launcher which works, but I can't run it in my Forge installation with my other Forge mods, doing so gives me the above crash.

 

I Installed Forge first, then moved Optifine to mods folder, then double clicked it to run the installer. Is this not the right process?

[Wabooe]

I give up.

If you check the changelog for Optifine 1.15.2, it says that it's not compatible with Forge.
