We have Gateway Manager for GSX installed on a Mac Pro. Also, we have macOS Server setup on it as well. Everything used to work just fine for net booting. Suddenly, it stopped allowing Netbooting. I'm thinking it had to do with the Server App update or when upgrading to High Sierra. I can see all the NetBoot NBI's in the boot manager on the Mac I want to NetBoot from. When I select the correct NBI I wan't to boot to, it just boots straight into it's internal HD. I can get NetBoot to work fine on a Linux box but for whatever reason, something with Apple has changed something.
Anyone experiencing similar issues?
