Here the extire story so i was looking a texture pack and i found one so i downloaded it then once i log into minecraft i took my texture pack that was on off and then mc got laggy and i couldnt do anything for a minute or two then i finally got to move the mouse and put the new texture pack on and then mc black out and wouldnt let me even get to the mac laucher for a week or 2 then i finally got to the laucher and got to the mojang screen and then mc would sit their for 5 mintues or so and then say on the luacher report promblem to mojang so i thought it might be my mac but its not we called their support and they said it wasnt the mac and so i think it that texture pack but i delete the texture pack and now it just minecraft i tired to go on to other account on my mac but it still wont let me in so thats whats happen but the day before i got the texture pack mc close by it self and it did it 5 times so i stop thats what my description is of the promblem and let me know ASAP so i can fix it. (P.S. its my favorite game so i really am worried i cant play again and i can only play on technic which is a mod thing)
