I've managed to successfully install FileMaker Server v17 on a macOS Sierra Mac - installation went well once I skipped the screen where it couldn't find the license certificate.
After installing it went to open the Admin Console at:
but for some reason that page is not opening. I've restarted the Mac a few times and getting the same message in Safari that "Safari can't open the page https://localhost:16001/admin-console "https://localhost:16001/admin-console
Not sure where to go from here - any suggestions?
