Mouse and keyboard keep disconnecting
Ever since I installed MacOS Mojave (now 10.14.1) I have been having trouble connecting the Apple mouse and keyboard. Both had always been working fine (over a year).
Now they don't connect or lose connection when the mac wakes up. Sometimes they reconnect after a few minutes.
I have tried all the obvious thing like deleting the bluetooth list in Library/Preferences, but the problem hasn't gone away.
Sometimes it works, then the connectivity fails again.
A reply to a previous post about this suggested to restart the SMC, which I did and which solved the problem at the time. (the post was then marked as solved so I have to re-start the thread). However, it happened again today, so the SMC restart didn't seem to have been a permanent fix.
Is there anything else that can be done?
