Hi!! Today I was received an email from Apple to upgrade to MacOS Sierra GM, and like all years, I do it!! But this time I was surprised with a "Wi-Fi: no hardware installed"... I have a MacPro firstname.lastname@example.org with original Airport module (I have here to install a new BCM94360CD, but i'm waiting the adapter) and this monrning was working perfect!! (I was downloaded the 4.7Gb upgrade!!) I was done the fix of remove the .plist of /library/preferences/systemconfiguration but nothing... I'm without wifi... Some idea?? Thanks!
