If Pester 1.1b19 or 1.1b20 hangs, crashes, or otherwise fails to open

It is likely that you are experiencing a Pester bug related to your preferred speech voices (customizable in System Preferences or VoiceOver Utility). Unfortunately, in an attempt to improve Pester’s support for voices, I did not anticipate all the possible configurations until after 1.1b19’s original release.

• If you are using OS X 10.9 or later, please manually update to Pester 1.1b21 or later. There are no known issues with speech voices in this version.
• If you are using OS X 10.7 or 10.8, try re-downloading Pester 1.1b19 (the changes are in build 61; you can find the build number in parentheses after the version in Pester’s About box), which fixes some, but not all of the voice issues.
• If you are using OS X 10.7 or 10.8, have re-downloaded Pester 1.1b19, and it still fails to open, it is likely you have a Scottish voice enabled, or your default voice is a “premium” voice. You can upgrade OS X to 10.9 or later and use Pester 1.1b21 or later, go back to Pester 1.1b18, or attempt to change your voice configuration to avoid these issues.
