Updated to 10.13.5, lost Bluetooth

I just did the update this morning 6/10/18 and upon reboot my bluetooth mouse / keyboard are not working. I tried resetting the SMC to no avail. Everything was working fine before the update. I cannot even open the bluetooth settings under system preferences... mouse icon spins and does nothing until I force quit the sys preferences. Upon reboot, the mouse works for about 2 seconds and then stops. Repeat the process. If I only used the trackpad I might never even noticed the issue.

FYI:

One does not. A mouse is required for macOS recovery and restoring a time machine backup. However be aware that's unlikely to fix the issue and you should run hardware diagnostics before wasting your time.

My iMac is pro 5k and the MacBook Pro is also with retina display. However, my MacBook Pro with retina display which is very old now (mid-2012) updated with no problem in BT.

One thing I have noticed was the year of manufacturing, 2015! I have seen few 2015 here which nothing has solved their problem with BT.

I remove everything with fresh High Sierra 10.13.5 and nothing! I left my iMac turned off for hours with nothing plugged, still nothing.

I am hoping a new minor update comes fast. The next version is in beta with no mention of BT:

I am in the exact same situation! I update to 10.13.5 and after a restart, the BT is on with Off button greyed out! But it is not on as you can't connect to anything.

I have tested all the usual suspects:

• Thousands of restarts! Couple hundreds shutdown 😉
• Removing the plist,
• NVRAM/PRAM reset,
• SMC reset,
• Fresh Install: downloaded the latest High Sierra from Mac App Store, made a bootable USB, removed/erased my entire Volume and installed a fresh High Sierra. The version was 10.13.5 and a fresh install was exactly the same!!! Off button greyed out and nothing can connect.

So I had to restore by my Time Machine cause as annoying it is to not have BT and connect stuff by cable, I still need my files and apps.

I updated to 10.13.5 on my 2012 Macbook Pro with Retina (first generation) and it worked. But on my iMac 5k (mid 2015) it did not! I don't know what's going on.

BT loss seems to have happened to me too – update installation stalls at screens suggesting I need to switch wireless keyboard and wireless mouse on (they’re both already on). Problem is I don’t have a wired mouse/keyboard in the house. Software updates from Apple used to be sooo smooth. Not these days…

For me it worked to completely shut down my MacBook Pro. Not Restart, but completely shut down, wait a few minutes and switch it back on.

I had tried a few restarts, even removed all BT devices to try and reconnect them without success before.

Yes seems unlikely doesn't it. Though it also seems unlikely that quite a number of people's hardware would develop a bluetooth hardware fault immediately after installing 10.13.5.

Has anyone out there had their hardware repaired by Apple re this occurrence?

More info. Upon shut down for approx. 10 minutes and restart, I was able to access bluetooth options. My mouse and keyboard were listed there, but only the mouse was listed as "connected," although it was unresponsive. I attempted to remove and re-pair, but the laptop never "found" the device. Upon another restart, the previously removed devices were once again listed in the bluetooth settings. Feels like I'm stuck on this one. I hope a fix is coming soon.

I had to plug lightning cable from iMac into my wireless keyboard, then mouse, before they responded. Update had stalled, so I restored from Time Machine to previous OS version. Concerned about retrying update to be honest

Not really an option. Nearest Apple store is about 2 hours away. I put a call in to tech support and they had me reinstall the os, but that didn't solve anything. It's not a hardware issue... Update was crap. Too many people complaining about the same thing.

The mac indicates Bluetooth is on. But its not on nothing can see it and it cannot see devices. The devices work fine with another mac. The option to turn bluetooth off is greyed out.

The other mac is running 10.13.4. I am reticent about updating it.

I not there have been issues with blue tooth disappearing upon installation of other High Sierra updates.

Will try making an appointment at a Genius bar. Bur that will take some time as I cannot get there easily on work days.

Bluetooth mouse worked fine with other PC. Apple tech support had me reinstall the os. Nothing has helped. Very frustrated... First time I've had serious issues with an update. Laptop locked up on me last night for the first time ever.

Okay, I backed up to TM, connected my wireless keyboard into the iMac through a lightning cable as insurance, and carried out the 10.13.5 software update.

It all updated trouble-free this time. Yowsah.

just updated to 10.13.5. Bluetooth now completely broken. Cannot turn it off (option is grayed out), cannot connect to any known devices, new devices no appearing in list. Resetting nvram, resetting bluetooth module and deleting all bluetooth preferences does nothing. Thanks, Apple.
