    Hi there,

    Copying and pasting the apps in a different folder did not work for me in Big Sur. And @LAUNZON solution worked for previous versions of MacOS too.

    But seems that the "access" table now has 13 columns instead of 12 at least for Big Sur (and I think for Mojave too). So I opened the database to understand the values and was able to add UnityHub and Unity Editor in the Camera apps under the Privacy Settings.

    It did not solve my issue, which is related with Vuforia and it seems something on their side and has nothing to do with Unity, however, in case you guys need to modify the database as @LAUNZON explained before in recent MacOS versions, here are the SQL instructions that you need to run to add UnityHub and/or Unity Editor:

    INSERT INTO access VALUES('kTCCServiceCamera','com.unity3d.UnityHub',0,2,2,1,NULL,NULL,NULL,'UNUSED',NULL,0,1608136079);

    INSERT INTO access VALUES('kTCCServiceCamera','com.unity3d.UnityEditor5.x',0,2,2,1,NULL,NULL,NULL,'UNUSED',NULL,0,1608136079);

    The "0, 2, 2, 1" are based on other app values that already have Camera access, and the same for the other data after except for the first NULL, which is a Binary for other apps instead of NULL, but should not affect the entry.

    The last value is for a date in timestamp format, use whichever you want. You also can run this instructions by opening the database file in TablePlus or SequelPro instead of using the terminal. Whatever is more convenient for you.

    Hope it helps.

    For me, both Unity and the Unity Hub are enabled in the camera privacy settings (I can't remember when and how I enabled it, but I'm pretty sure I did not done an advanced gymnastics to do it...)

    My problem was - which is somewhat related to what is discussed here, so I thought I share - the the *built macos application* crashed on webcamtexture.Play.
    Is seems it is also a permission issue.
    When I entered a string in "project settings/Player/Other Settings/Camera Usage descriptor" field, the crash went away - the built app will ask for camera access with whatever text you entered in the mentioned field.

    For a standalone mac build
    We've spent some time trying to get voice permissions as well while using Vivox. While it would attempt to join a channel, it would fail silently and not actually allow the microphone to transmit.

    We discovered that in addition to ensuring `NSMicrophoneUsageDescription`
    was in the plist in the mac app bundle package Contents when built, these entitlements also needed to be set:
    Then the signtool must be run (and a cert may be required)

    Both the plist and entitlements must be done. Only modifying the plist may cause the app to crash or fail to open as described above

    This should allow the app to popup a request for microphone permissions

    They seemed to have fixed it according to the release notes of the Unity Hub version 2.3.1:
    New Fixes
    For Mac Catalina OS, Hub permissions are now passed for camera and other Unity Editor related features

    After testing it I can confirm the issue is solved on OSX catalina 10.15.4 and Unity 2019.3.11f1, so update unity hub and you should be good to go!

    This is how I got my 10.15.4 Catalina to workaround this problem :
    1. Move Unity Hub and Unity folder from Applications to Documents( or any other place )
    2. Start your unity editor from Unity/Hub/Editor folder
    3. New camera and microphone permission are asked
    4. When wanting to use unity hub features ( like collab for instance ) move unity hub to Applications again and signin from the unity editor. When done move Unity hub back to documents.

    Maybe this workaround is useful for somebody.

    @ELMEGREN oh good to know that it can also work with SIP enabled, just wonder why it didn't for me.. glad that this workaround helped some people so far!

    I just wanted to report that I got it working using @Launzone's workaround *without* disabling the System Integrity Protection (my machine, a work laptop, prohibits me from doing so as it's firmware password protected preventing me from even going into Recovery Mode). "csrutil status" does report that SIP is enabled.

    I'm on Mojave 10.14.6 with Unity Hub 2.3.0 and Unity 2020.1.0b4.

    Thanks for sharing the workaround Launzone!

    @BORWICKA sorry i should have mentioned, this fix is for Mac OS Mojave (I am currently running version 10.14) so i am actually not sure how the situation was on El Capitan. It seems like those permission things changed.
