John,

THANK YOU for confirming that your installation of RC4 is compatible with Mac 
OS 10.14.1. I was able to solve the issue based on your success with Mac OS 
10.14.1. 

Knowing you had successful operation in Mac OS 10.14.1, I decided to revisit my 
WSJT-X preferences. When I installed both v1.9.1 and v2.0.0-rc4, the sound card 
input was pre-populated with "USB Audio CODEC" so I did not see a need to 
change this setting at the time I installed the apps. However, your note 
convinced me the problem was probably audio related.

For both v1.9.1 and v2.0.0-rc4, I launched the app, changed the sound card 
input preference from “USB Audio CODEC” to "Built-in microphone", saved the 
preference and quit the application. I then restarted the application, changed 
the sound card input preference back to "USB Audio CODEC" and saved the 
preference. After this action, the issue of "no decode when ENABLE TX was 
enabled" was resolved and normal app behavior was restored for both versions of 
WSJT-X. 

Thank you again for your feedback... it convinced me that I needed to go back 
and look at my WSJT-X preferences rather than suspect Mac OS of being the 
source of the issue.

ISSUE RESOLVED.

73,

Robert,

I read your two messages.   For the second message, are you being too 
impatient?    Your first TX must have been at 15:31:15 but you didn’t wait for 
a decode and halted transmit - why?   
Were you using Auto Seq or not?

Remember RC4 does not decode 75 bit transmissions.  At the moment there are 
only a few stations active on 20m and 40m with RC4.   So you may see much 
activity on the waterfall display with no decodes.   Perfectly normal at 
present until more stations use RC4.

I normally run 10.13 on my MacBook (SignaLink + TS-870s) but to test your 
problem I re-booted to 10.14.1 with rc4 on 40m and immediately worked a DL2 and 
OE6.   Everything is running normally and correctly.   Decoding continues when 
ENABLE TX is active (but the rig is not transmitting).

I do not believe there is any incompatability problem between RC4 and macOS 
10.14.1.

Perhaps have refresh of the Quick Start guide.
