We often run into Mac Bluetooth problems when trying to use a keyboard, trackpad or other Bluetooth accessory. This could lead to issues with your Bluetooth devices not showing up or a very annoying “Bluetooth Not Available” error on Mac.
The first thing to try is restarting your Mac and turning your Bluetooth devices off and back on. This can solve simple issues in a few minutes. Another thing to try if the Bluetooth device is acting erratically is to move other Bluetooth devices away from between the Mac and the trackpad.
Placing an iPhone 6 Plus between our Mac and a trackpad always causes issues.
