Bluetooth pairing an iPhone or iPad and a Mac is not supported.
If you are attempting to use Handoff/Continuity or AirDrop, that does involve Bluetooth but the devices are NOT paired; Bluetooth just needs to be on and the devices in range of each other.
To AirDrop photos, see: How to use AirDrop on your iPhone or iPad - Apple Support
and Use AirDrop on your Mac - Apple Support
The following may help with Handoff/Continuity issues: Use Continuity to connect your Mac, iPhone, iPad, and Apple Watch - Apple Support
