Unity Editor platform limitations

Apple

On macOS, secondary Editor windows only maximize, and do not enter full screen mode.

Apple silicon devices

The Apple silicon Editor has the following limitations:

  • Download and install of Apple silicon Editor via the Unity Hub is only possible through Hub version 3.0 Beta 6 or later, with some limitations in 3.0 Beta 6. For more information, refer to the Hub release notes:
    • To switch to the latest beta version of the Hub, change the “Channel” in Preferences > Advanced to “Beta” or re-download from https://unity.com/download.
  • If you are using Hub 2.4.5 and wish to use the Apple silicon Editor: uninstall the Apple intel version, download and run the standalone installer for Unity Editor (Apple silicon) from https://unity3d.com/unity/whats-new/2021.3.0, and locate it through the Hub.
  • The native Apple silicon Editor doesn’t support the CPU lightmapperA tool in Unity that bakes lightmaps according to the arrangement of lights and geometry in your scene. More info

    or import from SketchUp.

Linux

The Linux Editor has the following limitations:

  • Video importing is limited to the VP8 video format.
  • File systems are case sensitive.
  • If the Editor generates a Pipe error ! message, you must increase the maximum open file limit in your current Editor session. For example, run ulimit -n 4096 in the terminal before launching the Editor. For more information, refer to the Troubleshooting Linux Editor issues page.
