Even Bluetooth 4.0 will not work unless it has the "Smart Ready" designation along with it.
The problem is older Mac devices are Bluetooth compatible, but not Bluetooth "Smart Ready." There is a difference. As another person mentioned before, these are devices, that according to Logitech, work with Bluetooth "Smart Ready" devices. Understood that this is a reply over a year from OP, but response is posted here specifically for the latest Logitech Mouse MX Master 2S (July 2017) which is, similar in function to OP's device. Had this same problem which was solved by purchase of CORRECT Bluetooth device variant. You should also see the name of your connected Bluetooth device under the sub-head "Devices (Paired, Configured, etc)." If it does not, try to repeat the entire sequence. It should say the name of the manufacturer different than the native one internal to the Mac device. One of the ways you will know FOR SURE if this is the Bluetooth adapter in operation is checking the line "Manufacturer:". You can also cross-check this number/letter format by repeating steps 6 and 7 above. Your Bluetooth dongle *may* have a MAC (media access control, not to be confused with a Mac device) address like 00-1A-7D-DA-71-06, or similar format.ġ4. OPTION-click on the Bluetooth icon in the Menu Bar a menu drops down on line 3 you will see "Address" followed by the number-letter sequence of the currently operating Bluetooth transmitter. Verify now that the dongle's Bluetooth transmitter is the one that is connecting your device, and not the Mac's built-in Bluetooth. The USB Bluetooth device should now be working. When it does connect it will say "Connected" underneath the device name.ġ3. Moments later your device should now connect. To the right of it you should see a button appear that says "Pair". Your should see the name of that device appear a few seconds later in the right-hand column of the Bluetooth System Preferences screen. Activate your Bluetooth device such as a mouse, and switch it into "Pairing" mode.ġ2. Wait 3-4 seconds and then insert the USB Bluetooth dongle into a USB port on your Mac.ġ1. (If it is already off, then click it ON, then click it OFF right after.)ġ0. In the Bluetooth system preference screen, in the left column is the Bluetooth ON / OFF switch: Click to turn Bluetooth off. Now go back to the Bluetooth icon in menu bar and click. (Screenshot: Press Command-Shift-4 - Now marquee-select the area of the screen you want to capture as soon as you release the wired mouse or trackpad the screenshot is taken)Ĩ. Take a screen shot of this info- it is helpful so you can tell between this address and the Bluetooth transmitter address of your new USB-dongle. You should see the exact-same sequence of numbers and letters as in Step 5 above. Look at line 2 which also begins with the word "Address".
Now on the right side of the screen is the full set of specs for the currently-in-use Bluetooth transmitter. Column 1 begins with header "Hardware": The 3rd line down is "Bluetooth"- click to select it. You should now see your full system report. In the pop-up window that shows, at the bottom of that screen is a button "System Report". Now cross-check this information because it is the way to know when your new Bluetooth dongle is activated and in use: Click on the APPLE icon in the menu bar, select "About this Mac". If you did not yet plug in your USB luetooth dongle, the address you see should be your Mac's built-in Bluetooth adapter.Ħ. This is the specific address of the Bluetooth transmitter currently in use internal to the Mac device. Look at line 3, which starts with the word "ADDRESS:" You'll see a sequence of numbers and letters something like the following: 00-22-41-CE-46-24 (The letters and numbers you see may be different- that is OK!) Also, this line is greyed-out on the screen. This will drop down a menu which shows some additional info than just a regular click on the Bluetooth icon. Hold the OPTION KEY down and click Bluetooth Icon in Menu Bar. You should now see the Bluetooth icon in the Mac Menu Bar.ĥ. At bottom of the window is a checkbox: Show Bluetooth in menu bar. Open your Mac System Preferences, select "Bluetooth" under System Preferences.ģ.
DO NOT plug in your USB Bluetooth dongle before starting. Steps taken from "BayArea Shopper" posted 8/27/16 which worked for a solution on Mac:ġ.
