I am wondering what software for RTTY for Mac computers?  I tried loading cocoaModem, but my Mac would not allow me to load it as it was from an unauthorized developer.  I read somewhere the there is a Fldigi app. for Macs, but I cannot seem to find it.  They list a whole bunch of apps on their site, but I do not see any reference to a Mac version.  I am hoping to try RTTY with my 6500 in next months RTTY contest.  Any Mac users have a solution?  I am using Mohave OS.

Gene,
You will also need xDAX and xCAT from Mario DL3LSM.

CocoaModem is abandonware, not having been updated for years. The "unauthorized developer" warning is a simple security measure of macOS's Gatekeeper system, and you can bypass it on an individual basis by going to the Applications folder, right click on CocoaModem.app and select "Open." It will ask you if you're sure and you simply say yes. After that, the Gatekeeper system won't bother you again. However, let me stress that CocoaModem is abandoned with no future development, unlike Fldigi which is under continuous development.

For Fldigi, you want the Fldigi file called "fldigi-4.0.18_macos.dmg", available here: https://sourceforge.net/projects/fldigi/files/fldigi/fldigi-4.0.18_macos.dmg/download

And then, as Andrew pointed out, you'll need xDax and xCat.  Directions for setting Fldigi up to work with these is provided on the same page as xDax/xCat.

Gene,

It has been a few years since I used Mac OS, but when I last compared the two programs I found that cocoaModem copied RTTY better than FLdigi. Significantly better, in fact. I have no idea if this is still the case, but I thought it worth mentioning.

cocoaModem still works on High Sierra with Loopback and xDax / xCat. Integrates with MacloggerDx nicely. However, I don't use it much because I have switched to Fldigi with FSQ, Olivia, Contestia, etc, and cocoaModem does not support them. I find almost no PSK here, and really do not like RTTY.

If you have an "M" model 6xxx, or a Maestro, you don't need any other rig control - set up the pans and slices with the front panel / Maestro and operate with your favourite digital software on the Mac.
