Question

Operating System: Mac OS X 10.9.1 (Mavericks)

Java Version: Java 7 Update 45, also have Apple-Java 6 Update 65

Antivirus Program: Gatekeeper

Description of Problem:

When I start tekkit, it says that FML is setting some things up, but when the window appears, it's just a blank screen. When I looked at the console, it says that it requires a few libraries with lwjgl that aren't there.

No error messages, but look at the Error Log below.

I uninstalled Java 8. I'm a programmer, so I like to use Java 7, and that's why I have it. But when I remove Java 6, no java applications work, because the system isn't optimized for Java 7u45, it's optimized for the apple-provided java (6u65). So, the problem may be that I need to optimize it for Java 7, and remove Java 6.

Ugh, I hate Mac because the little knowledge I posess comes from windows.

Java 7 has been upgraded to 51, update it. Might be that you need java 6 then, thing is that java 6 is not being updated any more.

Caused by: java.lang.UnsatisfiedLinkError: Can't load library

This tells me that problem lies with java... According to oracle Mac users should use both java 7 and 6. That they can "co-exist". Yet a few users gets these kinds of errors... ugh!

Your a developer, you say? So your Java 7 version, its the JDK and not JRE, right? Because JDK has been known to cause issues. If thats the case, I'd recommend removing the JDK and replacing it with the recommended apple version for 7, and seeing if the issue resolves.

Tech Jargon time, since you've done java dev. We are getting a reflection invoke error deeper in the report, and that would indicate that something in the calling of the function has broke, as opposed to the function itself, IE java cannot find the normal 64 bit libraries that it wants, as its following the technic pack instruction set for them. JRE has a different structure, from my knowledge, that JDK, which means if JDK is the primary version of java 7, then the directions that technic pack gives would be pointing somewhere completely different, than they would be for regular java. End of tech rant.

Apple just says to download the JRE from java.com, and since my parents aren't home right now, I can't install the JRE (I need an admin password). I also forgot to tell you that some modpacks (like Lapitos Galacticraft Modpack) work, as well as the original minecraft from the launcher. It's just some, like tekkit and voltz, that don't work. Maybe it's because my java home variable is set to the wrong version or something. I don't know how to set the default java on a mac.
