Turning Off Wireless Control Interfaces:
Turning off unused wireless control interfaces, such as WiFi, Bluetooth, and Infrared, improves performance by freeing up system resources and reducing data corruption caused by EMI “noise” on sensitive internal circuitry.
Systems Mojo Audio sells with our optimized Yosemite have Infrared turned off because its rarely used and Bluetooth and WiFi turned on since they are often required to setup new system. I recommend turning off as many wireless control interfaces as possible.
Warning! Turning off wireless control interfaces can disable control devices, such as your Apple Bluetooth keyboard/mouse/pad. I recommend a USB keyboard and mouse for setup and troubleshooting.
For highest performance use no wireless control interfaces:
- Connect to the internet via Ethernet cable on a LAN.
- Control your desktop computer with USB control devices.
- Use your laptop’s integrated monitor/keyboard/pad.
- Use cables to transfer data between computers and devices.
The second-best option is to use only one wireless control interface.
Let’s start by looking at what works with what so you’ll have a better idea of which wireless control interfaces you’ll want to turn off.
Control devices associated with wireless interfaces:
- Most keyboards and mice = USB (wired or wireless)
- Apple keyboard and mouse = Bluetooth
- Apple and aftermarket remote controls = Infrared
- iOS and mobile device remote control = Bluetooth
- iOS and mobile devices remote desktop App = WiFi
The above list may differ from brand to brand or App to App and may even change over time. I recommend connecting a simple USB keyboard/mouse/pad and turning on/off wireless control interfaces one at a time and testing each of your control devices to confirm which works with which.
Note: Wireless devices that plug into USB have relatively low noise compared to WiFi or Bluetooth because they have external receivers, cause less EMI noise, and are better shielded from internal circuitry.
Turning on/off the infrared:
Go into the Apple Menu, select System Preferences, and click on Security & Privacy.
Click on the Advanced button.
Off: Check the box next to Disable remote control infrared receiver.
On: Uncheck this same box to activate the infrared receiver.
If a windows Lock icon is in the locked position, you must unlock it before making any changes. To unlock any window, click on the Lock icon; you’ll be prompted to enter your administrative password.
Note: the password for any Mojo Audio optimized system is “Mojo.”
Turning on/off the WiFi control interface:
Go into the Apple Menu, select System Preferences, and click on Network.
Click on and highlight WiFi in the left column:
Off: Click on the Turn WiFi Off button.
On: Click on the Turn WiFi On button.
Note: the color of the dot on the left of the networking interface goes from green to red when an interface is turned off and returns to green when turned back on.
Turning on/off the Bluetooth:
Go into the Apple Menu, select System Preferences, and click on Bluetooth. Click on the Bluetooth status button. Note the status changes.
Click on the Advanced button and additional Bluetooth options appear. Check or uncheck the options you want. Personally I uncheck them all.
Note: so that Apple keyboards/mice/pads work with our new systems we leave the Bluetooth on. I would recommend switching to a simple USB keyboard/mouse/pad and turning all the Bluetooth off.
