[OT] - anybody having trouble with 'Transmit' FTP client on a Mac?

[Graham Samuel]

I’ve got two FTP clients for my Mac (High Sierra), ‘Transmit’ and ‘FileZilla’. From time to time I put Windows executables on a server using these clients for future download and execution on Windows 10. Something strange is happening: with ‘FileZilla’ there seems to be no problem, but with ‘Transmit’, sometimes W10 reports:

“This app can’t run on your PC
To find a version for your PC, check with the software publisher”

The information about the exact size and date of the app seems the same on the hard disk and server versions, but it can’t be, can it? BTW the app is code signed.

Can anyone suggest what ‘Transmit’ is doing? Is it perhaps somehow indicating that the app is 32-bit? But wait, aren’t all LC standalones still 32-bit?

Confused
