No hardware found in System Information after clean install
I just did a clean install of El Capitan from a usb drive and erased the SSD of my MacBook Pro. When I go to System Preferences nothing appears in the Network settings. In System Information I noticed that there are a lot of hardware parts where it says: "No information found." Or "No hardware was found." This goes for quite some parts like Thunderbolt, PCI, Card Reader and Bluetooth.
It seems to me like drivers are missing. Is it possible that I might have deleted them when I erased the SSD? And if so, is it possible to install the drivers from Apple? Where can I find those?
Thanks in advance!
Is this a good question?
