EyeTV 4 works perfectly on MacOS 15 Sequoia AFTER a complete EyeTV un-install
EyeTV 4 works fine on my Intel Mac (Big Sur) but gave numerous crashes on my Apple Silicon Mac (Sequoia).
I struggled a lot before finding the work around : EyeTV 4 runs perfectly after a complete un-install on my MacBookPro M4.
To be sure to un-install EyeTV 4 completely, I used CleanMyMac. But other utilities should work too.
Then I re-installed EyeTV 4 with the latest installer : eyetv 4.0.0 (8532) (64-bit) MAC version.
Hope this helps.
