My friend has an iMac laptop (apple silicon, same as mine except mine is a desktop). She has jre 8 installed and jdk 1.8 (yes the arm versions where installed) installed on her computer, but when she tries to launch the custom modded instillation for my server that's 1.12.2 it says she does not have java 8 installed. Mine runs fine and I have had no issues, I did not need to force it to find any file. She does have jdk 25 and temurin 17 installed also, idk if that is causing an issue? We went through the instillation and forced it to find the java file by selecting it in the executable line , but after we tried that, it still says the same error message. When we launched terminal to try and find the home for java 8 it keeps finding some java plugin that's not the main java file. Even when we select the java file in the jdk 1.8 folder it still says java 8 is not installed! I know a bit more then her but I'm no expert. Can anyone here help? She can't play on our 1.12.2 server until I can figure out a fix. Any info or help is appreciated!

What kind of Launcher is used? The default Minecraft Launcher already contains Java 8 - so there is no need to install a separate Java installation

She didn't install Java 8 at first and tried to launch from my custom CursedForge instillation of the mods for our server (I legit copy and pasted the folder into google docs so she got the EXACT files on my instillation and on our server.. worked fine for my other friend), which opened the MC launcher and then when she hit "play" MC launcher said that Java 8 was not installed and that she needed to install it (this is for mc 1.12.2). So I instructed her to download it and no matter what she downloads, no matter how or where she tells the launcher to find it through the java executable tab it does not recognize her java 8 she installed (she has both jre and jdk). It's odd... is there a certain build or kind of javascript that will work while others break?

Her launcher version is 2.5.2 (1) same as mine, and her JVM thing is this (idk if it has something to do with that):
-Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

EDIT: I did ask her to copy n paste mine from my launcher into hers so it's this ATM should she change it back (idk what any of this means):
-Xmx4096m -Xms256m -Dfml.ignorePatchDiscrepancies=true -Dfml.ignoreInvalidMinecraftCertificates=true -Duser.language=en -Duser.country=US -DCFInstanceId=a163a4bd-74f6-4de6-8061-f3d4cd9eb284 -DlibraryDirectory="/Users/owner/Documents/curseforge/minecraft/Install/libraries"

I know nothing really just a bit more then her and I really want her to play on our server but her imac laptop hates 1.12.2 idk why (we only played this version bc my other friend who could join fine wanted mo creatures which is stuck in 1.12.2 sigh)any help is appreciated ty^^
