1. Configuration - iMac 4K - 8 GB RAM - 1 TB SSD - macOS 10.14 Mojave on APFS partition - wsjt-x for macOS - Windows 10 on NTFS Bootcamp partition - wsjt-x for Windows - microHAM USB Interface III - Transceiver Yaesu FT-450D
2. Problem - After a few hours of operation the output audio drops/disappears. This problem is not present on the same iMac with wsjt-x for Windows. This problem is not present in macOS and Windows with other software like fldigi. 3. Workaround - Completely removing wsjt-x for macOS with AppDelete and re-installing wsjt-x cures the problem for day or so. After some time the problem occurs very suddenly again. Everything worked fine and the next moment the output audio is gone. Kind regards, dr.
