I'm on macOS 10.13.6.

I often need to set a long process running from the terminal, and then lock my Macbook for a while, and I want the process to be still running when the screen is locked. However, the process just hangs as long as the screen is locked. I can confirm that the Macbook is not asleep, and I've checked the box that says "prevent computer from sleeping automatically when the display is off" in "Energy Saver". How do I keep the process running (not hang) when the computer is locked (but not asleep)?

  • Can you elaborate on what process are you talking about? – Nimesh Neema Oct 11 at 9:52
  • Any long-running process. A machine learning training run for example. More concretely, a Python program that takes ages (hours) to run. – Ray Oct 11 at 10:06
  • Do you use a sleep prevention app like Caffeine or KeepingYouAwake? apple.stackexchange.com/questions/89277/… and apple.stackexchange.com/questions/76107/… – Nimesh Neema Oct 11 at 10:16
  • I've heard of them, but as I said, the computer is not asleep. It's merely locked. – Ray Oct 11 at 10:45
  • I inferred that from the question. I was simply suggesting giving it a try and making observation. – Nimesh Neema Oct 11 at 10:47
  1. In System Preferences > Energy Saver, check the box for "Prevent computer from sleeping automatically when the display is off" (on laptops, this is under the Power Adapter tab)
  2. In System Preferences > Security & Privacy, check the box for "Require password after sleep or screen saver begins" and set the delay in the dropdown menu to "immediately"

Now, you can hit command-option-power to turn off the display without sleeping the computer, and doing anything that turns on the display (like hitting a key or clicking a mouse button) will prompt you for your account password.

  • Both are already ticked. In fact I've already mentioned in my question precisely what you mentioned in your point 1. This does not answer my question at all. – Ray Oct 12 at 9:11
