TEX LIVE UTILITY UPDATE FAILED MAC BLUETOOTH

I can't risk having a WiFi disconnect corrupt my SMB-mounted disks. I know you are being facetious when you use the adjective 'hilarious', but because of these WiFi disconnects I have stopped using my 2018 MBP and returned to using my iMac and 2016 MBP for system critical work. You can manually fix these WiFi disconnections by switching off your WiFi and then turning it back on. Note: In my hands, these WiFi disconnections are rare (I see them 1 to 5 times a day), random (there is no pattern to when or why they occur), and often intermittent (they will often fix themselves, typically in under a minute and usually by 5 to 30 minutes, but I've also waited over 16 hours and not had a WiFi disconnect fix itself - so they don't always fix themselves). The following link to a post on this forum explains some of these issues:Ģ018 MacBook Pros crashing with 'Bridge OS' error

I also experience the occasional bluetooth disconnections.

In other words, these WiFi disconnections are specific to the 2018 MBP. still maintain Internet and intranet connectivity to the same router while the 2018 MBP is experiencing a WiFi disconnection. All of my other computers, including other macs, iPhones, iPads, HomePod, AppleTV, PCs running Linux, Raspberry Pis, B&W speakers, etc. I have experienced these WiFi disconnections on four different WiFi routers also, so they are not restricted to just one router type.

These WiFi disconnects cause all other types of problems, for instance, I have experienced Safari disconnects, Software Update (macOS 10.14.3 update) failures, Mac App Store update failures, Mac App Store installation failures (Xcode, Logic Pro X, in particular), TeXLive installation failures, SageMath install failures, Time Machine backup failures (4 times for initial TM backup, 5th time took 5 and 1/2 days to complete, probably because of WiFi disconnects), AirDrop failures, rsync failures, ssh failures, ping failures, and even SMB-mounted HDD deleted files, all caused by the WiFi disconnection problems. I have performed packet capture (Wireshark) while the 2018 MBPs were disconnected and found that the WiFi hardware was still sending and receiving packets. These problems stem from a loss of the DNS information by the 2018 MBPs, all while the WiFi hardware is still working. It has continued through 3 different 2018 MBPs and all macOS High Sierra and Mojave updates. I've been having this exact type of WiFi disconnection since the very beginning of my use of the 2018 MBP.
