Hi guys. I just wanted to share and find out if I am the only one getting issue: My setup below: 1. Mac Pro 4.1 flashed to 5.1 2. OSX Yosemite - latest update I bought one of those Wireless AC + Bluetooth 4 LE combo cards to get Handoff and Continuity on my Mac. The card I have is similar to those sold by MacVidCards and OSXWifi. So after updating to the latest version of Yosemite, my Bluetooth will suddenly become disabled without any warning. The strange thing is the WiFi still works fine; it's just the Bluetooth that gets disabled. Unplugging and replugging the card enables Bluetooth but then the same thing happens within a day or 2. I have done things like resetting PRAM and also repairing drive and user permissions but without any success. Anyone else getting this problem?
