You'll need SwitchResX for this (yes, it's paid, but it you don't pay it just annoys you with a warning every day and disables some features, that's all). If you have two external monitors like me, you would find that it doesn't help at all.

I'm saying any number because the mirroring option suggested by other answers mirrors all displays. I finally found a way to disable the main monitor instead of hiding it for any number of external monitors. IMPORTANT: Go back to recovery (reboot with Command + R) and re-enable SIP using csrutil enable.Open your lid and the laptop display should stay OFF.Reboot and close your lid, keep it closed until you've logged in and see your desktop.Open terminal and use the sudo nvram boot-args="niog=1" command.Use csrutil disable command to disable SIP.When it loads, chose your language and use the top navigation bar to go to Utilities -> Terminal Reboot and hold down CMD + R during boot.To fix this we need to boot into recovery and disable SIP. Nvram: Error setting variable - 'boot-args': (iokit/common) general error It'll give you garbage like this instead: You need to run this command: nvram boot-args="niog=1" but it's not going to work unless you boot into recovery first.

This should allow you to use your Mac with an external display, external keyboard/mouse or even the built in keyboard including (the very useful) fingerprint scanner and lcd touch bar on newer models. I didn't find any working solutions in order to configure this on Sierra so I'm posting this for people looking for a solution in 2017. These settings are persistent, in that, they do not need to be re-applied every time the machine's power is cycled and are saved to the file: /Library/Preferences/SystemConfiguration/ To reverse the command, set the 0 to a 1. The -a, -b, -c, -u flags determine whether the settings apply to battery ( -b ), charger (wall power) ( -c ), UPS ( -u ) or all ( -a ). You can accomplish this with the following command: sudo pmset -a lidwake 0 You can do this using pmset, a local utility found on OS X that actually handles all your power settings. Once it wakens, it will enable the secondary display, but not the internal one.Īdditionally, you may set the attribute to leave the system in the sleep state even if the clamshell is opened. Once that happens, move your mouse, or hit a key on your keyboard to wake it. Once it does, close the lid on your notebook. Once you connect the secondary monitor, the system will recognize it.

There are two ways to connect a secondary display to your notebook without enabling the default screen (note that this does not mean dimming it, but rather turning it off). I had replaced the heat sink, re-applied a sane amount of Arctic Silver thermal paste, and used Lobotomo Fan Control daemon to monitor my system's temperature. You can conduct your own testing of course. Moreover, the newer models have far more efficient blade fans and would suffer even less from the effects of heat (additionally, the new Intel chipsets run cooler than their predecessors). I ran the system for well over a year with the clamshell open, and then closed, and saw no different in CPU/CPU temps (nor any variability in the other heat sensors) as a result. Personally, I have a 2006 MBP that was eventually relegated to being a desktop. Some claim that keeping the lid open allows the chassis to cool down, but these claims have never had any real data behind them (simply anecdotal evidence and unsubstantiated rumour). Ambient air is never in short supply and the "exhaust" (where the hot air picked up by the blade fan(s) are expelled) is located at the back of the unit (the black stripe on the newer models and the grey stripe on the first generation machines).

Having the lid closed or open does not impact the airflow of your MacBook Pro (MBP).
