Version 2.4.5 of App Tamer is a fairly tame release – it corrects a few nagging bugs, and is now checked for malware by Apple and notarized to indicate so. The menu bar icon shows its disabled state more clearly when running in Dark Mode on Mojave, and some processes were mistakenly listed in the “Managed Processes” list even though App Tamer wasn’t managing them (ironically, because of bookkeeping error, they were included in the list because App Tamer never touched them at all).
Full release notes and download links are available on the App Tamer release page.
