Using OS X 10.11 beta 1 on a Mac Pro 5,1.
Existing bluetooth connection (i.e. a connection to an Apple Trackpad set up in Yosemite prior to update to OS X 10.11) is present and works, but I am unable to configure new connections.
When trying to pair computer with an iPhone 5S the phone cannot 'see' the Mac Pro, nor can Mac Pro 'see' the iPhone 5S. However iPhone 5S has no problems connecting to other Bluetooth devices.
The Bluetooth hardware is clearly working - the track pad is operating without problem - which suggests the issue is with the 'discoverable' process.
Anyone else seen anything like this?
