Ok that sucks. If they do a scan, at least use the radio that's not in use so it doesn't affect the one communicating (e.g. use 2.4 Ghz when you're connected on 5).. That would be a good way to avoid this latency hit. Also, I'm assuming Maps only does this when it's open, but Apple's annoying tendency to keep an app running when you close the last window (with the exception of system preferences and a few others) makes this very hard to diagnose. While I still used Macs a lot I would always close apps with Command-Q for that reason. This behaviour would exacerbate the problem as the user isn't aware that the app is stil running. Apple's reasoning is I believe to "not worry about open apps, the OS will handle it". But it doesn't always, I often get prompts that my memory is full and I have to close something now or else... And that is with me being rigorous closing apps. My work buys only base level machines with standard ram, unfortunately.

Often the antenna is shared - its a relatively large physical thing. And it can't really be shared except time-shared I believe.

  The frequencies are different enough for it to be possible technically. The same way mobile phones can be active on multiple bands at the same time. But indeed the used chipset may not support it. It's something I would expect Apple to have taken advantage of though, as they own both the hardware and the software.

> Apple's annoying tendency to keep an app running when you close the last window This is…just how macOS works. Windows applications (generally) tie their lifecycle to the existence of a window, but Macs have a different paradigm: the program can live without any windows. Pretty much every Mac app behaves this way. It’s been this way as long as I can remember. iOS is different; you can force close an app with the app switcher, but the OS generally encourages you to leave things “open” and the OS will periodically wake your process so it can perform various tasks. The OS is very stingy about how much work your process can do when it’s in the background in this way. This is one of the challenges when developing for iOS, for sure.

  Yeah, I think OP is right that this behavior is confusing for Windows users, but as a longtime macOS user I don't find it confusing or problematic at all.

    I'm more a unix user than a Windows user. I use pretty much all current OSes (including Mac and Windows) on a daily basis but FreeBSD is my daily driver. I think macOS is pretty unique in this regard (as well as being the only that use Meta-C / Meta-V for copy/paste, something that still bites me every day as I switch between OSes :) ). But I only used macOS since 10.2, never used classic.

      Classic was the same. On older systems, I think it was a good idea, given the speed of hard drives back then. With SSDs, the performance gains from keeping unused programs alive are far lower, but at the same time, RAM is far more plentiful, so it comes at a much lower cost.

      I had the same issue with copy/paste on MacOS, until I couldn't stand it anymore and used software to remap the keys. I swapped the builtin Fn, Ctrl, and Meta keys around so they are positioned like you'd expect on a normal keyboard (and a normal OS), and it instantly fixed my issues without any other negative side effects aside from having to learn another key combo for Ctrl-C in terminals. I highly recommend the Karabiner app, it makes this change trivial. There's also a way to do it without additional software, described here: https://apple.stackexchange.com/questions/88897/how-do-you-make-the-fn-keyboard-button-work-like-a-ctrl-button https://apple.stackexchange.com/questions/88897/how-do-you-m...

        Thanks, I'll give that a try!
