. So, how did you do without Java 7 ?

So, it is possible to use technic launcher on my mac, or have I to stay on my weak laptop with Linux ?

Hello, I have the same problem with Mac OS X 10.5.8 and the latest version of techniclauncher : when I click on the .jar, I have an error message too. I have Java : -J2SE 5.0 32 bits 1.5.0_30-b03 - Java SE 64 bits 1.6.0_26-b03-384 - J2SE 5.0 64 bits 1.5.0_30-b03 - J2SE 1.4.2 32 bits 1.4.2_22
