cant join servers after updating minecraft launcher

after i updated minecraft launcher to the new fancy one i cant seem to join any of the servers or realms ( i play on mac yosemite 10.10.5) not sure if i was hacked. playing on 1.10.2 with an outdated texture pack.

PS idk what affect versions means because i cant seem to find 1.10.2 or 1.8.8 so i just put something random, so far ive only tried 1.10.2 with optifine and 1.8.8 without. none of them work.

all happened after i updated, using mac :|

PS if having a correct username in the 'profile' place ive written InfiKnight_ which is supposed to be InfiKnight_VIII which is my real minecraft username.
