Battery life. Mirroring drains your MacBook faster than a toddler on an iPad. Keep it plugged in if you’re marathon-watching The Bear or working late. Your laptop will thank you, and your power bank won’t cry.
Also, privacy: when you mirror, everything on your screen is broadcasted. Yes, even that tab with “how to be a better liar” open. Close sensitive windows before connecting. Future-you will be grateful.
