MCreator.jar could not be launched on Mac
Tue, 09/04/2018 - 06:23 (edited)

I recently downloaded mcreator 1.8.0 for my MAC (not windows) computer. When I tried to open mcreator.jar, however, it got this funky error message:

mcreator.jar could not be launched. check the console for possible error messages.

can somebody help?

BTW I am using Java 8 8u181.

Try to run it from the console and see the error message there. Then open a support ticket with the error log from the console on our issue tracker.

thats all I get.

Is there any other, more easier way? All this complicated computer stuff is melting me away.

If this is the only error you get, this is Mac related and not to MCreator. I suggest you to asking for a fix for this error on a macOS related forum or simply googling this error.

I googled tutorials (video form) for downloading Mcreator on mac, and the only good tutorials are from 2014. It is 2018 and the only installation videos are for WINDOWS!!

I need someone to give me the best tutorial. Opening the .jar file does not work, I have no knowlege of computers, and this mod maker is the only way I can make my first mod. And yet, It seems as if it is not able to run on a mac.

Is there a fix for this "mcreator.jar could not be launched. check the console for possible error messages." message, or am I better off not downloading Mcreator?

This is the problem. Set Java 8 as the default version on your Mac.

Sorry, I set Java 1.8 as the default JDK, and it still doesnt work. I guess Mcreator is only a Windows thing ):

Thanks anyways. Unless there is a solution to this madness.

There are thousands of users that use MCreator on Macs.

What is the result of java -version command in the terminal?

export JAVA_HOME=`/usr/libexec/java_home -v 1.8` is what i'm putting in

i do "java -version" next, and it says this:

java version "1.8.0_181"

Java(TM) SE Runtime Environment (build 1.8.0_181-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

That is good, but when I open another Terminal and type in "java -version" again, it says this:

java version "9.0.1"

Java(TM) SE Runtime Environment (build 9.0.1+11)

Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

Which is not what I want. I might just need a bit of help actually switching the default JDK to JDK 8.

BTW I'm using MC 1.12.2, which has it's own terminal for some reason.

Yes, MCreator has own bash instance. You need to add this export java_home command to the end of your .bash_profile to make it global, not just for the current terminal.

I also have Zero computer knowledge and I love to watch video tutorials, as I have a hard time reading.
