WSJT-X suddenly stopped working on my FTDX10 and Mac mini 2018 with Big Sur 11.2.1. See screen shots below.
After trying the usual remedies, I uninstalled WSJT-X, did a restart of the Mac, reloaded WSJT-X, and reloaded the driver (making sure to disconnect the USB cable). It still will not run.
WSJT-X preferences shows two drivers installed: /dev/cu.SLAB_USBtoUART and /dev/cu.SLAB_USBtoUART2 Neither one works. How can I delete them for a fresh start short of reinstalling the OS?
