When I attempt to install Unity Hub or manually download and install Unity 2019, Mac Installer throws this error message:
“Unity.pkg” can’t be opened because Apple cannot check it for malicious software.

Is Unity working to resolve this?

Could you please tell what ‘shadercompiler’ is ? I can’t find any folder like that.

My case:
I use Catalina. I’ve installed 2019.2.11 and faced the same problem with shaders. I decided to use your suggestion, but can’t understand what is ‘shadercompiler’. I installed the 2019.3.0b11 and tried to find something there. But didn’t find anything. Could you please explain what to do in details?

Thank you in advance!

Open up the Unity.app package ( right click show contents, go to the tools folder and find the shader compiler, copy that over the same place in the other version of Unity )

Hope that helps

Thank you!
However that not helped. I’ve found UnityShaderCompiler file in 2019.3.0b11 and copied it to 2019.2.11

Still having issues like:

and so on…

@nickrapp Hope you guys fix that, because this is not good. I can’t do build for iOS on Catalina

Hi @IndieFist , are you able to give me a bit more information on this? I am trying to install 2019.1.11f1 on a used Macbook Pro (mid-2015, reset to factory default, Catalina installed) and cannot see this option.

By the way, I’ve found such thing: if I try to install unity version with Android/iOS marks checked, but without NDK(for android) checked, this version would not be installed. However if you check NDK to install the version would be installed normally

Go to https://unity3d.com/get-unity/download/archive
Then press instead of Win or Mac download, the green button that say “Unity Hub”, then this app will be open and download this version,

Awesome, thanks @glad . I’ll definitely be needing this checked so it’s good to hear that’s working.

Thanks @IndieFist , much appreciated. I had downloaded the installer and had forgotten that this was an option on the Download Archive page. Giving that a go now.

EDIT: That worked! Thanks for the help!

I would also recommend that you download the latest Hub (2.2.0) as it has been notarized which generally results in less issues with installing unity components from it as its now a trusted source.

I have an old project that needs to use Unity 5.6. I tried both 5.6.1f1 and 5.6.7f1 but Unity is “not responding”. Checking the Console app of macOS I saw:

I’m using macOS Catalina 10.15.1

Any clue how to fix this? Thanks.

Actually, just create a fresh new project with Unity 5.6 and the Unity Editor is stuck at that error message.

It would be great if someone from Unity Technologies would say a few words about all the problems with Catalina. I mean if someone is fixing issues and give some forecast or explanation, just for us to think what to do next.

Can you give me a link, please ? I can’t find your issue. Thank you!

By the way I can’t find any issue related to Catalina and shaders problem.

They gave me a link to following issue and closed my bug report.
