I understand that the "hardened runtime" enabling happens at codesign time,
so this should arguably be a feature of macdeployqt. It's not there yet though,
at least according to https://bugreports.qt.io/browse/QTBUG-71291 .  If you're
right that this will become mandatory for macOS 10.15, it arguably get a higher 
priority; feel free to comment, including a link to the source of this 
statement.

For the time being, it seems you've to execute the codesign call yourself.

 

This is what I've done at work to prepare our builds for this. We use CMake 
though and we're already running codesign manually.

 

The notarization is annoying and takes around 5 minutes for Apple to run their 
virus scanners or whatever they're doing, so at the moment we're doing it only 
on Git-tagged CI builds (releases), not on every commit. What this gives us 
currently is that the macOS "do you want to run this" prompt will say "Was 
scanned by Apple on blah blah and found to look good" or something.

 

Will be more annoying if/when macOS starts to demand notarized builds, because 
then we'd need to do notarization of every commit, or force testers that wants 
to test a random build to turn off that checking (which I assume is still going 
to be possible through System Preferences).

 

Apple, sigh, I can understand and sympathize requiring signed builds, but this 
mandatory "virus scanned by Apple" is a little silly. As a user I trust the 
virus scanner I pick myself more than some blackbox process on Apple HQ servers.

My guess is that macOS will allow you to “override” the need to have the app 
scanned just like you can do now by right-clicking the app and clicking “open”. 
They would have to or developers wouldn’t be able to run their own apps or 
testers wouldn’t be able to run test apps. I don’t think macOS has gone the 
full “App Store Only” model yet, those days are coming. Still it would be good 
to get a definitive answer through Apple docs as to whether Notarization is 
mandatory or just strongly encouraged.
