I need to prevent my 13' 2016 MacBook Pro from sleeping. I'm using the Sonnet Echo Express III-D and when the Mac sleeps, all cards in the devices are disconnected and won't come back until the Mac is restarted or Thunderbolt 3 cable is removed and reconnected. I have a case open with Sonnet, but until then, I don't want my Mac to sleep.
Trying to get a Mac to sleep automatically after a certain amount of time can be frustrating. Several things can interrupt the process, including network activity and stubborn apps. Fortunately, you can use a handy tab in Activity Monitor to quickly diagnose what can keep your Mac from sleeping. Here̵
7;s how.
Let’s first open “Activity Monitor.” You can find the app in the folder Applications> Tools, or you can use “Spotlight”. Click the “magnifying glass” icon in the menu bar, or press Command + Spacebar. When a search field appears, type “activity monitor” and press “Return”.
When Activity Monitor opens, click the “Energy” tab.
On the “Energy” tab, you see a list of active processes (apps and background system functions) with information about their energy impact. Look for a column heading labeled “Prevent Sleep” and click on it.
If you see a “Yes” in the “Prevent Sleep” column, your Mac will not automatically go to sleep while the process is still active. If it is a process that you recognize, you can wait for an active task to complete, or try “Exit” the app. If it is a process that does not behave as you expect or refuse to close, you can force it to stop.
To force a process to close in Activity Monitor (on any tab), select the process from the list and click the “Stop” button, which looks like a small octagon with an “X” inside.
When Activity Monitor asks you to confirm, click “Force Quit”. After that, if that process was the only thing that prevented your Mac from hibernating, then your Mac should go to sleep the next time you expect it to.
If your Mac is still not sleeping
If you did not find an app that prevents sleep in Activity Monitor, you can dig deeper into the problem with a command-line tool called pmset. Overdrive app problems. Youtube app on mac. However, that tool requires a much deeper Mac troubleshooting experience to find out the cause of the sleep issue.
No matter what happens, do not stay up all night and try to find out – remember to sleep a little yourself. If you have problems, try a glass of warm milk. Good luck!
