i have the same issue

[Shadow1752]

Me too! glad Im not the only one. I want so far as to delete my old Launcher, Delete my minecraft and everything else in the folder, and then reinstall.

OSx 10.7.5

Launcher 246

I should have java 6 but im not certain.

no antivirus

Even Vanilla will not load

P.S. I thought that it might be helpful to add that after I have selected a modpack in the Launcher, A blank, white window opens. After a few seconds of no activity, the window closes and the launcher is no longer open.

Ok, i may have found the issue. Go to Macintosh HD/Library/Java/JavaVirtualMachines and delete everything in it.

The laucher should initially open a square with the normal java symbol called start. Then, a few peices of paper with a coffee cup and a pen should open, titled "Technic Launcher" If it doesnt open that, it will NOT work. Just close the launcher and reopen until it happens

Thank You so much!!

It worked, thx alot you guys

When I use the go to tool in finder, it tells me that the folder java does not exist...

Any help will be appreciated greatly.

So I found the folder under HD, and I deleted its contents. My problem has NOT resolved itself. Only the start icon will appear. Is there something that I am missing or have forgotten?

Try opening java prefrences and make sure only Java 6 is in it

[Shadow1752]

I actually just installed Java 7. I was already having this problem with Apple Java 6.

Startup has not changed one bit since I updated either...

I followed the instruction exactly and That didnt change anything.

If you deleted everything in your JavaVirtualMachine file make sure you put Java 1.6 back in there before you try it.

The Launcher works fine til we reach when we try to launch any mod. Your solution just fixes the start up for the launcher and not the mods crashes as fast you try to start them, proof reading maybe?
