Hi,
tested back and forth with different versions.
If reaper is configured to use the Eucon plugin for controlling AVID surfaces, Reaper 5.986 on MacOs (Mojave 10.14.6) crashes on start up.

It is also confirmed by the crash tracelog as follow

Try the non-notarized version of 5.986, available here:

Let us know whether that version works, thanks!

Hi,
with the 'non-notarized' version of 5.986 it works fine!

BTW, I have also give it a try with the 5.987 version (issued in the same day of 5.986...) and also 5.987 shows again the crash on Reaper start-up.

Hope it helps

Thanks

D.

Sorry for the trouble. AFAICT the notarized versions enable the "hardened runtime" on macOS Mojave and later, which seems to be incompatible with the Eucon SDK. For these versions we will continue to provide unnotarized downloads, via the _un suffix on the main download link. Hope that helps!
