If needed, sign into the App Store and go to Purchases. It should now have a Debug menu showing.ĥ. Open Terminal and run the following command:ĭefaults write ShowDebugMenu -bool trueĤ. If it is open, quit out the App Store applicationģ. Go to a machine that does not have Server.app installed.Ģ. However, it is possible to make the App Store leave behind a copy.ġ. To install Server.app, the Mac App Store will download an installer package from Apple, install Server.app, then delete the installer package as part of the post-installation clean-up. However, if you have already purchased Server.app, it is possible to get a copy of the Server.app installer from the Mac App Store. One problem with that is that Server.app is only available via the Mac App Store and doesn’t have a separate installer available for download. As part of building a custom OS X installer ISO for my ESXi server, I wanted the ability to include Server.app as part of my installation process.
