Hi! I have bought Mac mini (Late 2009 base model) recently, and since I want to use it as HTPC (Plex, EyeTV, Logitech Media Server) I have ugrade it to 256GB SSD and 8GB RAM. Before I have installed RAM upgrade I have installed El Capitan on 256GB SSD and 4GB RAM (factory default). After RAM upgrade I can not see any WiFi and any Bluetooth devices... The airport and Bluetooth card is visible in system devices list. Has anyone encountered such a problem, and could help me? P.
