gainerfull

go into ~(username)/Library/Application Support/techniclauncher/technicssp/mods then secondary click on the zip file named "EE2ModV1.38.zip" and select get info, then rename it to "zEE2ModV1.38.zip" i was having the same problem and was messing around with the order that the files were loaded and this is the one that worked and i did some research and it is the actual way to fix the problem. i have played for 19 hours without a crash using build craft pipes to automate all of my machines. hope it helps

The simple solution for the incompatibility of Aether and ANY other mod, is to just put it as a build option on technic launcher like being able to choose between technic, tekkie, hack/mine, yogbox, voxelbox, and vanilla. i'm not joining either side in this battle just saying that google is your best friend for questioning or bug fixes and that arguing isn't going to get anyone anywhere.
