I want to launch Tekkit on my iMac but it ends with a white screen. I tried this solution but that did not work out for me.

Perhaps because I am doing something wrong? I use Java 7 update 21. Maybe that is the problem? It works on my Macbook by the way.

    Either remove all plugins and then add them back one at a time until it crashes or remove one plugin at a time until it doesn't. Then you would have found your culprit. – ChrisF Jun 15 '13 at 10:28

    I'm voting to close this question as off-topic because it's for modded minecraft support and we can only help with vanilla minecraft crashes. – Virusbomb Jun 27 '19 at 14:11

Here are the things to try (I have a Mac, which I barely use, but when I had a mate over, this happened):

  • Try using different builds of the tekkit. This can be done by clicking the "cog" or settings symbol underneath the mod pack
  • Try using java 6 instead of java 7. Also try uninstalling java7.
  • Ensure that your mac is able to actually run the game. If it is an old mac, it is likely unable to run tekkit due to the amount of mods
  • Buy a PC. Cheaper and less issues.

Have fun

Go to %appdata% and go to .technic and delete it. That's for windows and mac.

    Can you elaborate on how to do that? What is %appdata% and how do I go to it? Why does this help? – fredley Oct 20 '13 at 17:38
