Hi I am a new Mac user and I have been a software developer on the windows platform for 15 years now. A few months ago I purchased a refurbished 2011 15 Macbook Pro. I purchased Apple care as well as the IOS developer subscription. Im not a Linux person so Im figuring this stuff out as I go. So after a recent update my MBP stopped my wifi every time I closed the lid or if the screensaver kicked in. So I went through all the settings and changed everything I could find such as disabling the sleep mode and screen saver. After searching the web for answers I found a keep alive script that didnt work because I received permission denied messages. So then called Apple to ask what I could do. They told me there is nothing I can do because its supposed to sleep when you close the lid. So keeping calm I asked this person, how do I connect my Apple TV and Ipad to my MBP if it kills the wifi connection? He said leave the lid open. I told him it worked before and he said well it shouldnt have! I said what? I have to burn hydro and have a bright laptop screen to my right when I want to enjoy a movie while lying in bed and using my Apple TV? The guy said yes. Have a good day. Thanks to a friend of mine who is a knowledgeable apple person I got a tool to keep it awake. Im going to donate to that developer for this free tool. I just cant believe the difference in service from going into the store where everyone treats you well to the phone service where they say live with it. I just needed to get that off my chest. Has anyone had this problem with their wifi recently? Thanks for listening.
