You don't need to think of it much as all modern projectors these days are compatible with Apple devices, be it Apple laptops, Apple phones, iPads, or iMacs.  However, Most Apple users face a common issue: the projector's standard connectivity option - HDMI port. Since all modern Apple laptops come with the thunderbird port, the connection between them becomes challenging.  In that case, you can buy a thunderbird to HDMI adapter. If it is your iPhone, you can buy The Lightning Digital AV Adapter.
