Our Power Manager condition will use a combination of the tmutil and grep tools to know when Time Machine is running.įor the technically inclined, the tmutil output is almost in JSON format. We can use another tool, called grep, to determine if which running line appears in the output. When Time Machine is idle, the line reads: Running = 0 When Time Machine is running, the line reads: Running = 1 Note the line near the base of the output that reads: Running = 1. Launch Applications > Utilities > Terminalĭepending on Time Machine’s status at the time, the result will look something like:ĭestinationID = "00000000-0000-FFFF-FFFF-00FF00FF00FF" ĭestinationMountPoint = "/Volumes/Time Machine Backups".Try running the command tmutil status and looking at the result: For our immediate needs, tmutil provides enough information to work with but I would avoid relying too heavily on the format remaining unchanged. The tmutil tool is not ideal because the output format is undocumented and may change between versions of macOS.
We can use this tool to determine when Time Machine is running. Thankfully macOS includes a command line tool called tmutil tmutil stands for Time Machine Utility. As a process running on macOS, visually checking a menu is not possible. So how do you know if Time Machine is running on macOS? As a user, the Time Machine menu bar icon is the obvious location to check. Condition > Edit (cog menu) > Optional (pop-up menu) > Invert.Thus if you find it easier to check for the postive nature of a condition but want the negative outcome, do this by inverting the condition: Thus you could add a condition to check if Time Machine is running, then invert the result for the evaluation. Inverting ConditionsĪs an aside, individual conditions can be inverted within Power Manager. Only if an event’s conditions met, will the event’s actions be performed.įor this recipe, we need to add a condition that only passes if Time Machine is not running. Conditions are parts of an event that are evaluated when the event it triggered but before the event’s actions are performed.
#MAC DONT SLEEP HOW TO#
Let’s look at how to give Time Machine priority over inactivity triggered sleep. However, there are environments where giving Time Machine priority over sleep is desirable. Interruptions and changes to the Mac’s environment are expected and Time Machine will pause and resume its tasks as needed.ĭepending on the version, macOS will postpone idle triggered sleep when Time Machine is running.īy default, Power Manager will not postpone inactivity triggered sleep when Time Machine is running.
#MAC DONT SLEEP MAC#
Time Machine is designed to work on a Mac computer that is being powered on and off, going to sleep and waking. The back-up is inexpensive, private, and, once set-up, need not be thought about again. If you do not have Time Machine set up on your Mac, I highly recommend it. Commonly the external device is a small inexpensive hard drive plugged into your computer by a USB cable. Time Machine works in the background and quietly maintains a copy of your files and folders on an external storage device. Time Machine is macOS’s included back-up solution.
In this recipe, we walk through how to add this condition to your sleep event. You can tell Power Manager not to put your Mac to sleep while Time Machine is running.
