Hi everyone!

I am having a lot of trouble updating to mine craft 1.12. I have an iMac computer. Whenever I try to go on mine craft 1.12 this comes up:

Exception in thread "main" java.lang.UnsupportedClassVersionError: net/minecraft/client/main/Main : Unsupported major.minor version 52.0

If any of you could help me log into 1.12 that would be greatly appreciated!

Thanks!

Make sure your Java version is up to date.

I have it up to date but it still doesn't work

Are you sure? This issue is caused by outdated Java. If you can play other versions of Minecraft besides 1.12, you may have outdated Java.

Still try downloading the latest Java version, just in case.

If that doesn't work, then I don't know how to fix it.

Having it installed does not mean MC is using it, check the launcher settings and make sure MC is set to use Java 8.

I believe VBOs is on, You might turn it off in the settings before going on a map or server.
