i would really really love to play some modded Minecraft, especially the rlcraft modpack. Im on Mac (high sierra right now) and i downloaded the twitch desktop app, installed Minecraft on there and everything else, also java, but:
1. the twitch app doesn't recognize that i already installed java in the Settings>Minecraft>Java Settings, it rather tells me "Java was not found on your system. Please install Java and refresh".
and 2. every time i press play on a modpack, the game launcher starts (via java btw) and gives me this error after pressing play again there:
Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option PermSize; support was removed in 8.0Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option PermSize; support was removed in 8.0Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28)
with my (really limited) knowledge i tried everything to deinstall everything java-related i found and reinstalled it via the link given to me by twitch, i even tried to download different versions of java via different sources... nothing makes a difference! Please somebody help!
I also tried out different changes to the JVM Arguments, but no progress there ether...
This problem was already kinda addressed in this post, but even though it seems to work for others this does not work for me at all (and hammy0013).
So please, if somebody has any idea what i should do or has any questions, please tell me!
Huge Thanks to anyone who reads this and tries to help! :)
