Hey guys I've been having a random problem with my MBPr. At random times maybe once very other day Safari will not connect to internet. Restarting Safari does not fix the problem, clearing DNS cache in terminal doesn't help either. Turning wifi off and on does not help... Only restarting the computer helps. Have not tried clearing history and caches as I hate losing all of that but it was done maybe 10 days ago last time I just don't remember if it helped the no connection problem. When Safari stops working Chrome and Firefox still work fine... About 2 months back I think I had some melware that was causing some problems but that was fix by running AdwareMedic. I am not a 100% sure but I think this problem might have started happening then... Any suggestions are much appreciated.. Its really annoying having to reset my computer all the time. . .
