I am having very strange issues with my MacBooks Airport functionality. Sometimes I cannot get any networks to show up at all. I tried a restart but even after that the issues persists.
I already purged the usual files also mentioned here
Since I even booted the computer from a MacOS 10.14 Boot device with the Wi-Fi still not seeing networks, I am suspecting a sort of hardware issue. However. Booting into Diagnostic Mode and running the tests does not show any issues.
Only booting the Mac in Safe Mode once and then booting back into normal mode solves the issue for some time.
What does Safe boot do with the Airport hardware or any other software to make it work again?
