Installing Unity on macOS Catalina

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!

 

its my pleasure read that help you

 

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:

Unsupported 32-bit executable: "/Applications/Unity/Hub/Editor/5.6.1f1/Unity.app/Contents/Tools/UnityShaderCompiler" error message."

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.

Thanks a lot!

 

Hello, I have to use Unity 2017 1.2f1 because our VR headset doesn't support further versions. Since I have updated the system to macOS Catalina, I can't run any project in Unity 2017 1.2f1. It never loads

 

I had to re-install macOS Mojave to be able to build my old game. Unfortunately when uploading to Google Play Console I encountered:

More details: https://developer.android.com/distribute/best-practices/develop/64-bit

Unity Editor 5.6.7f1 doesn't support building Android 64bit. So I guess I'm stuck here and has to use Unity 2018 and convert my old code (sigh).

 

@glad have you been able to build on Catalina yet? Looks like I'm experiencing a similar issue:

I fallback to 2019.2.4f1. This is the only solution for me

 

Thanks @glad ... I currently have 6 versions installed but hadn't made it back that far. Installing it now.

 

are you fix it? how to do ?

 

Unable to install 2018.1.9f2 on Catalina, neither via install-assistant nor Unity-Hub. It saids, Unity can't be installed on this disk, the contents of this disk can't be changed.

anyone can help me fix it?

 

Same here.
Tried installing 2019.2.9f1 with no luck and with the same error.

 

same thing for me

 

same thing for me

 

Hello, I can´t install the unity hub on Mac Catalina 10.15.2. after installation it says it cannot be opened and it have to be updated...?

 

@andrews_unity Right now it is not possible to install (Unity Installer download) any version of Unity on Catalina 10.15.2, notarization error appears. Also it it not possible to launch latest version of the Unity Hub (I didn't have it installed before, installed it now)

 

Any solution to this? I can't install on any of my macs. They all run Catalina 10.15.2

 

@andrews_unity Thanks, I managed to solve it. Can't wait to get crackin'...

 

@andrews_unity When can this be expected?

What's the current "official" recommendation? Is Catalina supported by Unity (2018.4 and 2019.2/3) or not?
I read conflicting stories about it. Some people say it works, others seem to have serious problems with installing or building/running.

Still can not install unity by the unity hub in Catalina.

Installation has started, but then failed without any message

 

That method does not work for me, gets me the "Unity can't be installed on this disk, the contents of this disk can't be changed." error.

 

Hmmm,,,, Please have a look at this. Might be why many of us are getting the disc can't be changed error. Installer is trying to install to the wrong, read only, volume?

EDIT

In Unity Hub changed preferences for where Editor installs to a known writable directory, I chose Documents.

Successful install.

 

Hey guys! I had the issue too "Unity can't be installed on this disk, the contents of this disk can't be changed.". But I realized it's being after unlock my mac, so I turned "put hard disk to sleep when possible" off in System Preferences -> Energy Saver. The unity installation finished fine.
Or don't let your mac go to sleep, it will work too.

 

sad day. app is ready to ship... can't ship... need to upgrade to catalina, to get Xcode that lets me ship.... so I upgrade to catalina... unity 5.6.4 does not work anymore. and is unsupported. so no way to ship game. have to update game to newer unity which will break the game as unity car physics changed... Unity.. whenever you update physics... you should allow use of old physics engine as an option. sad day....

 

Xcode 11.3.1 runs on Mojave, you don't need Catalina for that.

 

Hello,

The thing is actually very simple - You just have to allow Full Disk Access for Installer (read/write permitions) in System Preferences/Security&Privacy/Privacy. After that, just run Unity installer, and it will pass with no problems at all. Cheers!

 

So this is what worked for me after setting up a new Mac with Catalina and trying to reinstall Unity (Hub 2.2.2 had the same issue as described that it downloaded the version, processed for a while and then silently ended up with "No Unity Version"):

• Install any Unity Editor version that you actually don't want w/o Hub. Either use one of the workarounds from above for the Download Assistant (haven't checked that further after the mentioned issues with writing to disk and also wouldn't be comfortable with elevating Installer permissions), or simply install one of the plain .pkg installers straight from a patch archive (these do work).
• Go to Unity Hub and add that Unity Editor via the "Locate" option.
• Next install the desired version via Hub. This will now work. It's only the first install in an empty Hub that fails.
• Remove the unwanted version again from Hub and delete it in filesystem.
• From now on, always first install new Unity updates next to the existing before uninstalling it. (Or wait until Unity fixes this, but it feels like Mars flight will come earlier...)

Is this problem fixed yet? I'm trying to install on a mac so I can build for iOS. Many of the solutions listed above start with "download via unity hub...". Unfortunately, Unity hub has the exact same issue. It refuses to open to due some nonsense about the inability to check for malicious software. I'm trying to download unity 2019.2.

 

I am running into this issue on Unity 2019. I am also having trouble installing the unity hub itself on catalina.

 

Installing the Hub itself is no issue at all. It‘s just not a Apple-signed app, so you can‘t open the installer with double click. Use right mousebutton menu, choose „open“ and then click again „open“ on the warning dialog (which you don‘t have on simple double-click). This is a standard procedure for every app that is not installed from Appstore.
After installing the Hub, continue with the procedure I explained before. This works around an actual Hub bug.

 

Thanks! that worked. I was positive I tried that, but I guess not. I'll try to install unity itself now

 

Yup, I am able to install and run unity. Thanks a lot!

 

What's the update here? I am 100% unable to open the Unity application on Mac OS 10.15.13. I click the icon and the app gets stuck on "Verifying..."

 

All versions of Unity are still failing to install or launch here with Catalina, regardless of whether gatekeeper is enabled or not or what access I give the application. UnityHub itself seems to be responsible for a tonne off asserts in the system log too, rejection of commands as not memory managed, insane number of wakeup calls, even a crash in ketchup (missing dll).

It's quite frustrating to not be able to use or launch the software you're paying so much for via a subscription, so many months after the OS update happened.

 

Have you tried my described workaround from above? It works w/o further issues on Catalina, and it should for you, too...

 

Go to the url of unity version release notes

then download the unity editor pkg file and install

 

Yeah, except it did not.

Only way is to install _any_ Unity editor via Hub on OSX Catalina is if you set in Unity Hub the path to one of the following paths:

• /Users/USERNAME/Applications
• /Users/USERNAME/Documents
• /Users/USERNAME/Downloads

Make sure you have added Unity Hub in System Settings > Security & Privacy:

• Full disk access
• Files & folders
• Developer Tools

If you miss any of those, installing via Unity Hub won't work!

After you installed your selected Unity editor, add it in System Settings > Security & Privacy:

• Full disk access
• Files & folders
• Developer Tools

The problem Unity Hub developer team still needs to solve
Using FaceTime camera in OSX Catalina crashes in Unity editor play mode if you launch it from the Unity Hub. What is the solution?

1. Unity dev team needs to make Unity Hub ask for the proper permissions (Camera, Microphone) but until it is not done jump to (2)
   
2. Move Unity Hub to the Bin from Applications, and launch Unity editor separately and play a project in editor which uses camera, and it will it asks for permission - for the Unity editor only, but not for the Hub!
   
3. Note: You have to move Unity Hub to Bin from Applications each time you want to test the camera in editor mode,
   
4. Note: You have to restore Unity Hub each from Bin to Applications each time I want to use collab

Anyone knows a better solution I would happy to read that post.

 

hI,
Im using Unity for a gaming module at uni, im being asked for a license as soon as i open the Hub? my tutor and other students have never been asked for a license when using the free version. I am on the latets OS catalina, as i got the mac this week. is there a way around this? because i can't open my gaming project without a license apparently. really strange as my tutor said hes never been asked for one
