I updated to 10.13.5, lost Bluetooth. I "reset" the module, trashed the BT preferences, nothing worked. Help?
MacBook Pro with Retina display, macOS High Sierra (10.13.5), iPad Pro 9.7, Watch 42mm, iPhone X
I have unplugged all cables from my laptop (external video, power cable etc.) and shutdown it for 10 minutes. After starting it up again, bluetooth was available again.
Note that rebooting or shutting down for 1-2 minutes didn't help me.
Good luck!
Reverted to 10.13.4 by time machine backup. Still no Bluetooth. Also stried switching off resetting Pram, resetting Bluetooth again, etc. to no avail.
Hardware issue right after this update (10.13.5)? Which is unavailable now at AppStore. Diagnostic founds no problem with hardware.
Software updates don't cause hardware problems. If that was the case, then reverting to the previous version would have resolved the issue.
Can you test your mouse with another machine? If not there's always the option of a mail in repair.
If it will make you feel better I'll take it to work and try it on my laptop there. I know it's not a hardware issue. Worked fine up to the minute I installed the update.
It works perfectly with other Apple products. It worked well until the .5 up
That didn’t work. But thank you v
After some days absence 10.13.5 has appeared again as an available update in the App store. Should one give it another go?
If you try just write if bluetooth is available. Tnx
Should you choose to do so, please let us know how you fare. Thanks
Reinstalled 10.13.5 (having reverted to 10.13.4). Still no Bluetooth. Symptoms as above.
Exact same problem after 10.13.5 update.
Tried all the resets you can do, reinstall, deleting preferences files, restarts, shutdowns etc etc.
Macbook Pro (Retina, 15 inch, mid 2015)
obviously NOT true in this case.
My Mac is now going into Apple to be reviewed by a tech on Tuesday :/
