bluetooth corrupts after restart
hi
So I bought a new imac recently
Model Name: iMac
Model Identifier: iMac17,1
Processor Name: Intel Core i5
Processor Speed: 3.2 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 16 GB
And nearly every time i restart my mac the bluettoth seems to corrupt, which is really helpful as it comes with a bluetooth mouse & keyboard. This means I have to dig out a wired mouse and keyboard go to preferences ditch and restart - which does seem to resolve the issue, however a couple days later its back to square 1
Any ideas??
Any help or advice greatly received!
iMac with Retina 5K display, OS X El Capitan (10.11.4)
