Hi, today (Saturday) is the last day for returning the machine. The only issue I have with this machine is pairing with bluetooth keyboards. The rest are fine (with the understanding that the popping is just a software cover up). Spent 1.5 hours with Apple and another one hour with Logitech. They cannot solve the issue but they said that they would follow up. They did point the finger at each other. Apple did a screen sharing and I sent a file for them to analyze my machine yesterday. They said that they would get back to me but haven't heard from them. In this case, should I keep it or return? I am getting a bit tired of backing up, uninstalling, reinstalling, etc.
