Short answer: Yes
NOTE: For Epic Games Launcher, Unity, and all other software that is pre-installed on your MacinCloud server or installed by request, you must provide your own licenses and credentials
Game development is possible on MacinCloud servers and, in the case for Managed and Pay-As-You-Go servers, there is a variety of software pre-installed geared towards game app development. These include Epic Games Launcher, GameSalad, and other development apps. Further apps can be installed by request (Or on your own in the case of Dedicated server users, who have admin rights).
Developing with Epic Games Launcher
Epic Games Launcher is pre-installed on most Managed and Pay-As-You-Go servers. If you don't see it under the 'Applications' tab in 'Finder,' don't hesitate to contact our support staff and request it be installed on your server.
(Note that you must provide and utilize your own license and account credentials to use Epic Games Launcher on your server)
Developing with Unity
Unity can be installed onto your server by request (For Managed and Pay-As-You-Go) or by yourself if you're a Dedicated server user.
To request this be installed on your server, simply contact our support staff and detail the version you want installed as well as what components you want included.
(Note that you must provide and utilize your own license and account credentials to use Unity on your server)
