My phone is acting up and I don't think I can rely on it to wake me up.
It's important that I wake up on time, and I'm looking for a Mac program that I can rely upon, even when the computer is asleep, unplugged, or with system volume levels uncertain.
I downloaded "Wake Up Time - Alarm Clock" (the first Google result for "alarm clock Mac"), but the UI and documentation are ambiguous. I couldn't even figure out how to set the alarm within 1 minute, much less have confidence that it would work.
I next downloaded "Alarm Clock", which was recommended in a 2012 Meta Filter thread. The app is no longer updated (it seems to have been last modified in 2007), but it reportedly "continues to work with OS X 10.9X." UI is clean (clear prompt to go into preferences if I want it to wake computer from sleep). And easy access to use mp3s avail in iTunes. I'm giving it a try. Fingers crossed.
Anybody have confidence in any other programs?
