This gist assumes that you have remote desktop set up to view your mac1.metal instance graphical user interface (GUI)
If this is not the case, use this gist including the prerequisite steps to be able to view the mac1.metal GUI.
Open Safari:
Go to id.unity3d.com and log in if you have an account.
You will be offered the download for Unity Hub once you have either logged in with a pro account or agreed to the personal account terms and conditions. (If not, go directly to the download page, and click the Unity Hub download link).
Accept the download from the site.
View the download using the download button, right-click the download and select open.
If you agree to the license you can install Unity Hub by dragging the Unity Hub icon onto the Applications icon. Be patient as the GUI is likely laggy and the operation is also slow. After doing this once, wait about 30 seconds, and the Applications window will open. (If the Applications window doesn't open after half a minute or so, double-click the Applications folder link
Inside the Applications window, near the bottom is the Unity Hub icon now.
Double click to open it. You will be asked to confirm, since it was downloaded
Unity Hub will open, and you will be told you have no license. Log in to your Unity account, using the same credentials as you did on the web site. The Activate New License button will be enabled. Click it and select your license type.
Once a license is assigned, we will install the version of the engine that we want. Go back to the main screen.
Choose Installs from the sidebar.
Click the Add button top right. Pick the version of Unity that you wish to install. If you have an existing project, you may want to use the same version as was used to create it, or the documentation may recommend a version. If not, the recommended release is the latest long term support (LTS) version, or you may want to use the latest official release.
Click next. At least add Visual Studio for Mac, and Android build support and iOS build support for your mobile application, and other platform(s) and/or languages as needed. You will need to agree to click-through licenses to continue. The install will start.
Installation steps requiring privilege escalation may require you to type in the instance password again. The process may take a while, so walk around and refresh your beverage.
After installation, the bar stops moving.
Use the sidebar menu to select the projects page to add or open a project.
