Hi all,
We advertise our app to be supported on 10.11, .12, and .13 and is downloaded from our own web site. The package signing is performed using Apple Developer and Installer certificates. Installation works great on 10.12 and 10.13, but Gatekeeper kicks in on 10.11 and pops-up the "...can't be opened because it is from an unidentified developer." dialog. Again, this happens on 10.11 only.
Anybody else run into this, and does anybody have any ideas on how to fix this?
Thanks
