Hi, I recently removed my airport card from my late-2013 macbook Air. I did it because I didn't want wifi access to the internet. (Please, I don't need advice on pros/cons of not having wifi access. I just don't want it on this device, even the capability to turn on and off the wifi. Period. thanks!) However, now all these unforeseen and seemingly unrelated problems are occurring. For example, I get "errors" all the time. Every time I open iTunes I get "Error (-50)" and my iPod will no longer sync with iTunes when I plug it directly into USB. What the hell does that have to do with the "iTunes Store"? Strangely, other things happened, too, such as my time/date resetting when I powered it back on after removing the card. This is hard to understand since I always had wifi turned "off" before this and the date/time/location was set. Makes me think the Air was connecting to the internet in the background without my permission for all this stuff. My main question is this: How do I get it through to the Air that it will not be connecting to the internet over wifi anymore, and to stop trying? For updates, I can connect using an ethernet connection. I just don't want to be bothered all the time by this thing trying to connect wirelessly when I don't want it to. Note: I have already removed the wireless connection from the Network settings. Thanks for any advice!
