So this has happened a couple of times. I will get the 'connection lost' window for my apple bt mouse. When that happens my computer crashes. Every time. It just freezes. Nothing works. MBA 2013 13".
I suspect you are not seeing replies as this is a puzzler. I have never seen anybody report this on the forums.
Just a thought though. I don't see how a BT device disconnecting could cause a crash. I am wondering if you have a crash underway and the that is causing the BT disconnect just prior to the crash.
What are you doing when this happens?
Take a look in Console for log entries at the exact time this happens to see if that gives you any tips about what is happening.
I also have the WiFi issue and Apple support told me to tell my IT Department to change their security settings. Yeah, change the security setting for a Fortune 500 media company with over 5,000 employees.
Because Apple has ceased building products that work properly. Yeah.
