Pester

Pester is designed to let you set, dismiss or snooze an alarm or timer as quickly and painlessly as possible, entirely from the keyboard if you wish. Alert options include sounds, speech, Growl and OS X notifications. Use Pester to remind you to catch the bus or attend an upcoming meeting.

• Fix yet another crash on launch because the (undocumented) storage format for speech voice selections changed again in macOS Sierra (10.12). Pester now preferentially uses SPI rather than trying to parse files on disk, which may be more robust to future changes. (Apple’s documented methods for obtaining voice lists have not kept pace with changes in how voices are downloaded and activated.) Thanks to Ed Heltzel for the report.
• Work around a bug in macOS Sierra (10.12) which broke keyboard navigation in the Read Me window.
• Set initial keyboard focus in the Read Me window to the text pane, rather than the contents pane.
• Fix a regression in which the width of the contents pane in the Read Me window was not constrained.
• Update to the current version of Sparkle.
• Support natural-language date and time entry on macOS High Sierra (10.13), by linking to Perl 5.18 on OS X 10.10-macOS 10.13
