I encounter some issues when I upgrade Mac OS to EL Capitan. My Bluetooth accessories and connectivity has problems. Someone told me I can fix it in the following way. Shut down your Mac and Press the power button and then press the Command-Option-P-R keys on your keyboard > Make sure that you get those keys pressed before the gray screen comes up or it won't work > Hold those keys down until your Mac reboots again - you'll hear the startup chime twice > Let go of the keys, and PRAM is now reset. But this issue still can permanently solve in my Mac with El Capitan. Any advice to get rid of this issue?
