I often run into the situation where the OS will suspend some of my apps because of low memory. If I am lucky, a window will appear that allows me to select which apps I want to quit and which apps I want to resume, which works reliably and is fine. However, often that window does not appear. This is usually the case when my machine (mid-2015 MBP 15", 16GB RAM, OS X 10.11.2) has just woken from sleep. In that case, the only symptom is that I have a bunch of unresponsive apps that show as (Not responding)
in Activity Monitor.
I have tried to resume processes by sending the CONT
signal (either via Activity Monitor or via the Terminal) and for a small number of apps this works, but for the majority of apps it does not. For example, when this happened to me just now, I force quitted Preview (which was the chief memory hog) and tried to resume the other apps with CONT
. This worked fine for Clear, but not for anything else. In some cases, such as Emacs, it had no effect – process still shows as (Not responding)
. In other cases, such as Bibdesk, it leaves the app in a strange unusable state where the main window refuses to appear on screen and the menus don't work.
So how can I force that process management window to appear, or otherwise do whatever magic it is doing to "resume" apps?
Best Answer
More googling revealed that the process management window I am looking for is the "Force Quit Applications" dialog, and that it can be easily accessed from the Apple () menu or with the keyboard shortcut
Command Option Escape
. In normal use, this only has aForce Quit
button, but it should also have aResume
button if the system suspends any of my processes again (although I can't directly test this at the moment).
