Hi,
I seem to be at the point of maximum stress in trying to figure out what is causing this problem. Minecraft loads successfully into the main menu without a problem, but after I generate and enter a single-player world, I get about 10-15 seconds before I experience a huge lag spike and it kicks me out of the world and freezes on the "Internal server shutting down..." screen. It never crashes so I have no error report, but I have uploaded my log to dropbox because it was too big to fit on pastebin.

I know that I have 5 ID Conflicts left, but I have resolved most of the others and I doubt the 5 that are left are whats causing the problem, right? Also, this error seemed to start after I revised a few more configs so that I would have less conflicts (and yes, I deleted any old saves after doing this).
Here are my system specs as well (if they aren't in the log already):
MacBook Pro
15-inch, Mid 2012
Processor- 2.6 GHz Intel Core i7
Memory- 8GB 1600 MHz DDR3 (4 GB Devoted to Technic Launcher)
Graphics- NVIDIA GeForce GT 650M 1024 MB
Software- OS X 10.8.3 (12D78)
Java Version- Version 6 Update 45
Thanks SOOO Much for the help!
