For nearly a month now I have been experiencing problems with Tekkit Classic. After selecting the Tekkit Classic modpack and clicking "Play" on the launcher, the TC window opens, stays black for 3-4 seconds, then instantly bugs out. The screen changes from black to a checkerboard pattern with graphics clipped from random open windows that constantly changes and flashes different graphics and colors and never changes to any other screen. All other modpacks work in the launcher, and I have not found anyone else on the internet with the same problem or a solution, for that matter, so I decided to make a topic. I even upgraded my operating system for it. Here's my specs (I know I have a really old Macbook but it works)
MacBook
13-inch, Early 2008
Processor 2.4 GHz Intel Core 2 Duo
Memory 4 GB 667 MHz DDR2 SDRAM
Graphics Intel GMA X3100 144 MB
Software Mac OS X Lion 10.7.5 (11G63)
Yes, I've reset the modpack, uninstalled and re-installed the launcher, deleted and replaced minecraft.jar, etc.
Any and all help would be greatly appreciated Thanks!
