Description
Simple ShutDownTimer(SDT) schedules either a Mac shutdown,  restart or sleep at a specified future date and time. A specific date/time can be specified or hours/minutes from the current date/time. Scheduled tasks can be terminated.


Version 1.07 ( March 2021 ) introduces:
  • A universal app compatible with macOS 11 Big Sur on Apple Silicon and Intel-based Macs.
  • Uses the macOS dark or light mode specified in System Preferences
  • Requires macOS 10.15+
Version 1.06 ( November 2014 )introduced:
  • Ability to schedule hours/minutes from current date/time
  • Ability to terminate a scheduled task
  • Retina display compatible icon
  • 64-bit for macOS 10.9+ and later on Intel Macs only.
Operation
Enter the date/time to shutdown/restart/sleep the mac and the administrator password. If SDT detects a scheduled shutdown/restart/sleep task upon launch, it provides  an "End Task" option which also requires an administrator password.
Notes
(1) Scheduled shutdown/restart/sleep does not persist after a shutdown or restart
(2) Scheduling is constrained only by date/time setting; other constraints such as detecting the end of another task aren't implemented.
(3) Uses the system 'shutdown' command. This will cleanly shutdown the system but does not give running applications a chance to cleanup.
(4) Digitally signed and compatible with Gatekeeper in OS X 10.8+
(5) The administrator password is for the account used to login to macOS. Every Mac login account is typically assigned a password( see macOS System Preferences>>>>>Users & Groups ) . SDT requires an administrator account; its password is what SDT needs to initiate a shutdown.
SDT versions 1.06 requires macOS 10.9+ and 1.07 requires macOS 10.15+.
SDT versions 1.00 through 1.05 require macOS 10.6+.
