  1. Apple is very bad these days. First it was iOS and now they are releasing unverified OS X updates to all users world wide. My iMac was just fine and WiFi issue started to happen only after updating to the 10.10.2. Thanks for the write up Niels.

    I did this on my MacBook and since then, it’s fucked up my internet. I can’t use Safari, App Store, iTunes, Mail, nor iCloud. The only app I can use to surf the web is Chrome. I’ve reset my PRAM and SMC numerous times and tried repairing my disk. How do I fix this?
