The Sentinel-fix worked for me as well (https://eyetvforum.com/index.php?/topic/316621-eyetv-4-with-macos-15-sequoia/). Thank you so much for the help AGB! Geniatech Support did not respond. Problem: Since I've updated my MacMini to macOS 15.4, EyeTV4 no longer works. As soon as LiveTV is started the app seems to crash / freeze and I can only "force quit". Using "EyeTV reporter", I've re-installed EyeTV and deleted all preferences, but it has not solved the problem. Specs: Mac mini M1, 2020 16 GB memory macOS Sequoia 15.4.1 EyeTV 4.0.0 (8532) EyeTV Hybrid Model EU 2008 Firmware 1.00 Solution: Search for "Sentinel Macupdate" ( https://sentinel.macupdate.com ) Download Sentinel and drag it to "Apps" Open Sentinel and drag the "EyeTV" app to the right side "Sign app with: Ad-Hoc" Problem solved 🙂 (more info: https://forums.macrumors.com/threads/macos-15-1-completely-removes-ability-to-launch-unsigned-applications.2441792/)
