Hey folks, I suspect something may be amiss with the release pipeline (or it may be a problem with this corporate machine, I don't have a non-managed mac to test on).

If I attempt to install with brew cask:

$brew --version
Homebrew 4.2.20-68-gb5b37d8

$brew install --cask keycastr

                   #         #           #            #                       -=O=-

    File: /Users/babbitt/Library/Caches/Homebrew/downloads/04fdf5108b9896fe4af232df6395a321e648bc69fcd9d17246d08cf9f90d649f--KeyCastr.app.zip
To retry an incomplete download, remove the file above.

If I attempt to download from the release link, I get an error message on launch. The application “KeyCastr” can’t be opened.

I've run the downloaded zip through virustotal (prior to unpacking), which found nothing, so I don't think there's a malicious actor at play, but it looks like something's wrong with the pipeline.

Could ya'll take a look at the archive integrity?

Thanks

Hi, I don't think there's an issue with the archive based on my own testing. Have you tried manually removing that cached download and retrying?

I have retried a few times, as well as downloading the file manually and copying it over the local artifact.

Brew works for other applications on this machine.

I'll dig around. Thanks for validating integrity. Must be something w/this machine.
