AI just made dummy display plugs the hot new MacBook dongle

If you’ve decided to fully immerse yourself in AI development, you’ve probably noticed how resource-intensive it is. For example, your Mac can never sleep because you need to operate your AI agents. So, what should you do if you are using a MacBook and need to move from one place to another? You can do what I do and walk around with a MacBook open. (I don’t even do AI development, I just don’t want to wait 1.5 seconds to wake up a sleeping Mac.)

Or you can do what developer Will DePue suggests on DePue points out that you can find these plugs for USB-C and HDMI at online retailers. In addition to NewEgg and Adafruit, you can find a four-pack of UGreen HDMI Dummy Adapters on Amazon for nine dollars.

Wait, what was that? Who is laughing? Wait, before you ridicule DePue for suggesting what you would say is a stupid investment, I was about to bring it up. You see, you don’t need a dongle to stop your MacBook from sleeping. You can use the Terminal and a caffeinate order online. Or you can use utility software like Amphentamine, which is free.

But as DePue points out, when you want to put your MacBook to sleep, you simply remove the dongle, which is faster than going back into Terminal to end the sleep. caffeinate session, or access a software utility to change a setting. That’s a big enough difference for DePue and probably many other people to invest. Some people think that convenience is worth $5 to $10.
