A:AnswerYes the monitor should work with a MacBook. Depending on which model your MacBook should have a mini display port or a USB C connector. The monitor has 1 DisplayPort™ 1.2; 1 DVI-D; 1 HDMI 1.4 (with HDCP support). You will need an adapter to get from your MacBook to the monitor. The maximum resolution for this monitor is QHD (2560 x 1440 @ 60 Hz). You will need to try different display settings on your mac to find which works the best.
