10.15.1 Update - Bluetooth not available

I ended up taking my Mac Mini into the Apple Store and they originally said it was a failed logic board and ordered a replacement for that. After they swapped out the logic board it still didn’t pass their tests so they told me they were going to order a new power supply and try that. I haven’t heard anything since last week, still waiting to get my machine back. Still find it off that all the “hardware” issues began right after I ran a software update.

I am having the same issue with my mac mini and bluetooth. i upgraded, and none of my bluetooth connections would work. at the same time, it didn't want to allow my USB mouse to work either. so i was really stuck, since i couldn't do anything. somehow i rebooted and returned to OS 14.6, and then tried to use my Time Machine backup i have on an external drive to things up the way they were before. now i find i can't do that, since something won't allow backup to work from that drive. i spent all day yesterday trying to return to the state it was in and can't. i got my USB connections going again, but still can't use Time Machine on the external.

I also upgraded my MacBook Pro, which for some reason seems to be more receptive. i have connected a Bluetooth keyboard that works

Having exact same problem. MBA 2012, has run without a glitch for 8 years until I updated to Catalina which rendered bluetooth "Not Available", with a squiggly line through the menu bar icon, and the Bluetooth preferences icon disappearing from the System Preferences window - a spotlight search indicates Bluetooth within System Preferences, however when accessed an error message appears: "You can’t open the “Bluetooth” preferences pane because it is not available to you at this time." I have applied all reset options detailed in this thread (thanks all for your hard work & sharing), alas none have worked for me. Just waiting on Apple now - please Apple, don't take too long, I was hoping my MBA would make it to its 10th birthday...

Thanks for the update, I have tried everything possible including a clean install rollback to Mojave, SMC reset and PRAM reset and nothing has helped. I will take it into the Apple Store and hope for some resolution.

Any update on a resolution PrestonG? I updated to 10.15.1 last week and lost Bluetooth ("Bluetooth: Not Available" on menu & "No Information Found" in System Report). I have tried everything except reinstalling the OS. I have a MBP 2018 and is < 1 month out of warranty.

Do you know if "their tests" were the embedded diagnostics accessed by pressing and hold the D key when the box is restarting? I only ask, because I ran that and it reported no issues/errors were found.

I have a mid-2015 macbook pro. Bluetooth connected to headphones (not Apple) but not keyboard. Keyboard is by Perixx, not Apple. Could that matter? I'm using USB keyboard to write this, so all USB works. I tried all the suggestions, nothing gets the bluetooth keyboard working. What?

Can't add a fix I'm afraid but experiencing same issue Mac Pro 2.3 2017 immediately after install of Catalina. Harware report says no information found. Done all the suggested fixes, none work. Clearly an update issue and it needs to be fixed, cannot use my headphones at all.

Apple tech could not find any hardware issues, but Bluetooth didn’t even show up on the hardware test.

This is my exact issue. All tests/diagnostics show nothing is wrong with the hardware. It is as if the Bluetooth module was completely removed from the MBP.

Please let us know what is found with the "deep dive".

Same issue, Bluetooth Hardware seems not to be available since Catalina 10.15.1 update (also if I check through System Report it indicates 'No bluetooth hardware available'). Tried restarts + deleting plist files.

One weird thing: I can still control my mouse pointer through my separate Apple Trackpad, which also works through Bluetooth, although it only supports movement and clicking, no gestures. It does not show anywhere as connected device though.

Hey,

I am also having the same problem, I am not able to connect my Airpods with my Macbook Pro (Catalina 10.15.1) since it is showing "Bluetooth not available". I have tried all the steps which everyone has already mentioned but nothing works.

This post is just to know if there are any updates on this issue or not .. !!

I've also tested diagonostic verification through 'press D' during boot, but there was no hardware error on its result. But still bluetooth is not working and even can't see the icon from system setting menu.

I think you’re correct. I have a 2012 MacBook Pro so I guess I’ve been abandoned by Apple. I was considering the Mini but I won’t be buying Apple due to error. I’ve gone old school going to usb keyboard/mouse.

Very disappointed!

Don’t bother going in for service. Had same issue with MCP. The issue is software related within Mojave . Apple doesn’t seem interested in fix. I updated to Catalina, and problem gone. MCP works just fine. On Mojave’s I reset everything, SMC, NVRAM, Bluetooth module , yet problem persisted. I’d open my lid and Bluetooth not available , unless reboot. Once updated to Catalina, problem gone, my Bluetooth has not ONCE been unavailable...

2 problems:

1. I have got "Bluetooth not available" on my Mac Book Air: Mac OS Mojave, Version 10.14.6. I have tried rebooting but to no avail. Any ideas?
2. I need to use a Magic Mouse because my trackpad is very insensitive, and only works some of the time – how, in fact could I fix that problem too?
