Mac Cannot Launch FTB

[Gabe224]

Hello,
I have been playing FTB every day and it has been working fine, that is untill today when I downloaded the latest Java Development Kit JDK 7u25 (I believe). Now whenever I launch FTB (vanilla still works fine by the way) the screen that should have ftb mnimizes into the bottom left of my screen and then when I expand it, and wait thirty seconds I get this message on the screen.

---- Minecraft Crash Report ----
// Hey, that tickles! Hehehe!

You have Java 7 and have a Mac. You can either downgrade to Java 6 using this guide. Or upgrade your Lwjgl to 2.9 I've heard both work.

 

[Gabe224]

Okay will do, but could you explain why Java 7 and mac dont work well together.

 

[lavarthan]

The link I've provided to downgrade contains the answer. The Lwjgl has updates that fix most (all?) the problems that the launcher experiences when Java 7 is used on the Mac.

From Ashzification our support tech.

It is out of FTB's control. It's a problem with the way Apple rewrote Java 7, and likely causes an issue with the way FML reads it. You'll get the same problem with every modded minecraft launcher.

Thank you

I just followed through with what the guide said and now whenever I launch FTB it crashes straight after the logo comes up, faster than before.

 

[lavarthan]

Check your console log. It might still be registering Java 7. If it does you could try following the guide again or try updating your Lwjgl. If it says Java 6 or you tried updating your Lwjgl and it did not work please post a new console log to pastebin.com

 

[Gabe224]

Updated Lwjgl, and now it works. Thanks so much!
