Get an error log (Also downgrade to Java 6, 7 isn't supported by Mac)

Well that made less sense then your first post

Try using Google

Try lowering the amount of RAM Technic can use. You should be fine with just 2GB of it

I guess your Processor isn't exactly powerful. Maybe the launcher is trying to extract/move too much files for it to handle

Go make your own bug report

We can't help you without an error log

[sarcasm] With the amount of info given, I'm sure we'll be able to fix this in No-time! [/sarcasm] (AKA We can't do anything without an error log)

Maybe you should post a bug report

We can't really do anything without an error log

Maybe you should post a bug report in the right forum section

Now what is this "Techkit" you're talking about? We've only got the Technic Pack on here

Okay ...Now, what do you want us to do?

It looks like Not Enough Items is conflicting with some other mod

Destruction Catalyst, Nuff said

Why not?

Automate every single process in the game without using Collectors and Relays to gain EMC That includes making HV Solar panels and all that stuff using factories

Not a launcher bug and you two above this should make your own bug report in the right sector

Well of course we can solve this issue without the error log!

There's ALWAYS an error log. They get generated even when the launcher didn't encounter an error at all

Disable your AV and try again

Thaumcraft 3 isn't even out yet, and the Launcher doesn't update mods as they become available This isn't even a bug

I think it is

I believe 1.4.5 is the version the latest Technic development build runs on

Post your own bug report
