I have been testing my modpack called Coldstone's Pack on the technic launcher. It was made on MultiMc with the intention of playing on a modded lan server with my friends. I have no problem when launching/playing this on my mac, however, my two friends are having issues with the game crashing while it is loading. One of my friends sent me their crash report log and I'm having a hard time figuring out what is going on. The one thing different from our situation is that I have a total memory storage of about 1900mb and my friend has about half that. He told me that he has played bigger packs than this before with no issue. Honestly, I have no idea what I'm doing, please help me!!!!
Try asking them to go to launcher options and allocating more GB if it says OutOfMemoryError. I don't know if it does or not because the links didn't work. They may have to use 64 bit java instead of 32 bit if they use 32 bit java. They can select latest 64 bit.
