I posted a fix here - Java 6 workaround - I run 10.8.2 but should be OK on Lion too.

I have it working now - here is what i did. As far as I can see technic Launcher and Java 7 dont play too well. Perhaps you can get it to work but I used this work around. NOTE that this is not supported by apple or me for that matter use at your own risk etc.. Assumes: You are running OSX 10.8 Java 7 latest and need to have Java 6 available for in this case technic_launcher 1. (re) Install Java 6 - you can get this from here: http://apple-java-for-mac.en.softonic.com/mac/download - it's a dmg/pkg and follow the prompts - it will install the final Java6 release 2. Create a launch.sh script with something like : export JAVA_HOME=$(/usr/libexec/java_home -v 1.6) cd /where your technic-launcher is/ java -jar technic-launcher.jar 3. Download the latest technic_launcher.jar for OSX - really do this evebn if you think you have done it before. 4. As a last resort - clear the cache / delete ~/Library/Application\ Support/techniclauncher Your latest Java 7 should be unaffected although I am still checking it over so as I said use at your own peril. NOTE WELL: Java 6 is obsoleted and will be vulnerable - be aware of this and take appropriate precautions to prevent any unwanted results. You know the score. I hope this helps you and anyone else in bother.

I have a couple of comments - I am having the same issue and although I haven't yet solved it I had a breakthrough in understanding the problem. Firstly - it's safe to ignore the java exception, its arises due to a null value in the custom zip property but I am sure that launcher handles this and just ignores the custom zip as you didn't specify one - as you will see the line immediately following this is: Loading Launcher from 'techniclauncher/technicssp So I am pretty sure it's 'something else' - BTW I have also tried: http://www.minecraftwiki.net/wiki/Tutorials/Update_LWJGL just in case but no dice. I'll keep you posted if I find anything. I think it's one of these pesky java updates... had quite a few issues on other java apps too.

any news on this? i have the same problem and am really running out of ideas.
