So our school has macs as the school computers, and ive seen people around playing minecraft in studies and such. However the normal way of using a USB cant work for me because they have removed terminal for the use of students. Also when i watched someone start up the game he opened it with flashplayer, or something adobe. Now i really have no idea how to do this but i do know that it is possible because ive seen it done. i just dont really have the time to ask them or figure it out myself. Sorry if that was a little vague, but i can try and give more details if they are needed!
Thanks guys.
