Summary:

The StartCalendarInterval key in a launchd plist doesn’t run a job after waking from sleep. According to the documentation:

“If you schedule a launchd job by setting the StartCalendarInterval key and the computer is asleep when the job should have run, your job will run when the computer wakes up.”

Steps to Reproduce:

1) Create a job that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>org.furbo.dim</string>
    <key>ProgramArguments</key>
    <array>
        <string>/Users/craig/bin/dim</string>
    </array>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>17</integer>
        <key>Minute</key>
        <integer>00</integer>
    </dict>
</dict>
</plist>

2) Sleep the machine at 16:50.

3) Wake the machine at 17:10.

Expected Results:

The /Users/craig/bin/dim script should run at 17:10 or thereabouts.

Actual Results:

The /Users/craig/bin/dim script never runs.

Notes:

If the machine is awake at 17:00, the script runs fine.
