Hello Rehabman,
First of all, thank you for all your guides and help to this forum, thanks to you I've been using Mac OS X on my u430 since 2015! Last week I decided to upgrade to High Sierra 10.13.1 and almost everything seems to work. I have the rebranded BCM94352HMB, Wi-Fi works but bluetooth doesn't even appear. Before deleting all the files on my laptop and clean installing High Sierra, I had El Capitan 10.11.4 and bluetooth worked sometimes (and no handoff), I couldn't use airdrop and after some time Bluetooth did not work at all. Now it doesn't show at all. Is there a solution to this issue? I attach you the files you ask for in Problem Reporting and I hope you can help me
