Bluetooth not available on Mac

Hi All,

Same situation on my 2015 iMac that after upgrading to the latest OS back to few months ago, this issue keeps happening. I brought my computer to Apple Store few months back and they replaced the bluetooth module for me.

However, the issue is still there after I plug my computer home so I brought over again. The 2nd time they replaced the main board. I thought that would be a very good arrangement for my better peace of mind but then the same situation happens again when I get home. So I brought it over for service again for the 3rd time but this time they refuse to do any service but simply telling me that they can't reproduce the situation, and ask me to go get my computer back.

To be very honest I doubt if they are really taking care of the issue at all. To me it is quite apparent that it is the latest OS crashing the bluetooth connectivity, or even worse leading to the bluetooth module disappeared all out of sudden, that it couldn't be found by the computer. Like most of you guys do, I need to use the cables to connect the keyboard and mouse to to restart (or more correctly restart a few times) the computer to gain the bluetooth module back.

The guy from Apple said they believe it is environmental related but I have been using the computer at the same spot for 2 years+ with no issue at all until I update to the latest OS, while I haven't added any devices around my desk. So it seems to be that it's only their make-up excuses. Besides, the interference would only impact the bluetooth connectivity but not resulting the bluetooth module gone completely from the s/w or OS aspect (i.e., the bluetooth icon greyed out with saw teeth on top).

Very disappointed with Apple so as their services. So if you have the same issue that you can bear with, better not bring it to service or it will be a waste of time and money.

Some months ago I had the same issue. I restarted my Mac but it was in vain. The clear information I found here https://osxtips.net/bluetooth-not-available-mac/

Use some of their tipps, that can help=)

Try resetting the SMC (again) and NVRAM.

Frankly, it is so intermittent I would suspect hardware. As you know, intermittent hardware problems are very difficult to diagnose and/or fix.

Same Issue with a lot of MBP 13 2014 & 2015 models.

I have around 10 macs doing the same in my office.

Deleting the plist and resetting the nvram did not help.

Apple needs to fix this ASAP.

I have the same problem with bluetooth Apple keyboard and Apple mouse.

MacOS 10.13.2

Apple, please fix this issue ASAP!

The problem still persists in Mojave. It is definitely software related, as a rollback to Sierra fixed it temporarily but the next update caused it to recur.

Hello there,

I tried everything (like deleting plist or SMC reset & ...) it didn't work.

Yesterday I updated my mac os to 10.13.2. Unfortunately I see the same problem again. Bluetooth is not available!

Same problem here: first appeared on my MBP 13" one month ago, and more recently on my iMac 27", where it makes the computer unusable because keyboard and trackpad stop working.

I tried several procedures like reset NVRAM, PRAM and so on, but they just fix it temporarily.

Both computers are on Sierra, I was considering upgrading to High Sierra but I see that the problem persists there.

Would be nice to have a fix soon, would be even better to not have automatic updates breaking things.

Same issue for me. A BT headset started being a little flaky after upgrade, now nothing works. BT mouse started to get super slow and poof, keyboard, mouse and headset no longer work. I can sometimes pair my mouse for about 30 seconds but it is slow and disconnects.

Same issue recurs occasionally on 27" iMac running High Sierra 10.13.2 - typically after sleeping.

Deleting the bluetooth plist works for me, but the problem recurs and is a real nuisance since my mouse is bluetooth (Apple). In fact, it's my only active bluetooth device (I do have an iPhone nearby and so continuity may also involve bluetooth).

Same issue here. I started having this problem within the past month or so and it's getting more and more frequent. constantly deleting a plist file and rebooting is not a solution; and considering the number of people reporting this, it's disheartening that I haven't seen anything officially addressing this problem. I was hoping there would be some fix in 10.13.3, but apparently not.

This is happening on my late 2015 27" 5K iMac.

Same here, MacBook Pro 2015 Early. Bluetooth and WiFi modules have been many issues since first Intel Macbook and Apple never fixed the drivers. That's when a company develops hardware and software together. Pathetic.

Bluetooth unavailable. Bluetooth no longer shows up in the preferences pane. This is after taking all advice resetting nvram/pram, resetting smc, deleting the plist file. Even reinstalled the OS. Nothing works. Pretty frustrating. Just wanted to add my complaints to the growing pile that apple needs to address.

You may disregard my comment above. After waking the machine from sleep, I again get the message "Bluetooth: Not Available."

I have now tried every one of the recommended fixes and the problem comes back after sleep and, when I go to System Preferences: Bluetooth and click "Turn Bluetooth On" nothing happens.

Restart reboots Bluetooth, but that's not a good solution.

Unfortunately, I continue to have this problem, even after updating to 10.13.3.

After my computer goes to sleep, Bluetooth is not available. Becomes available again after restart. The terminal: restart Bluetooth instructions also work, but sleep removes the service.

I have no USB peripherals.
