BTW, Apple is getting much worse along this dimension as well. They just alerted me that a future version of OS X will require me to submit Sigil to Apple so that it can be "notarized" otherwise it will not install or run. Even if properly code signed!
FWIW, If they go through with it and prevent unnotarized software from running I will stop my devloper id completely as it would then be worthless. Censureship of opensource software and preventing user choice is simply not acceptable. At that point, I ill simply move back to Linux and the Mac version can just bitrot.
Code:
macOS Mojave is here. Give Mac users even more confidence in your software
distributed outside the Mac App Store by submitting it to Apple to be notarized.
When users on macOS Mojave first open a notarized app, installer package, or
disk image, they’ll see a more streamlined Gatekeeper dialog and have
confidence that it is not known malware.
Download Xcode 10 and submit your software today. In an upcoming
release of macOS, Gatekeeper will require Developer ID–signed software to
be notarized by Apple.
