Apple's new Mac mini, MacBook Air, and MacBook Pro 13 are the first Macs to feature the Apple-designed M1 CPU,. While the M1 MacBooks natively support just one monitor, the M1 Mac Mini does natively support up to two external monitors - one via the HDMI port and a second via USB-C.

12" Retina MacBooks do not support the use of 2 external monitors.
