Hi guys,

I'm experimenting with the same issue currently.

What I can recommend to you is to try to install to the following paths: - /Users/USERNAME/Applications - /Users/USERNAME/Documents - /Users/USERNAME/Downloads

Make sure you have added Unity and Unity Hub in System Settings > Security & Privacy: - Full disk access - Files & folders - Developer Tools

Also, if you want collaborate to function, you need to use Hub, no exceptions I found so far.

@swpowe 's method can work as well, but don't forget to add the installation to Hub with 'Locate' under 'Installs'. In this way however, you won't be able ti use Hub's 'Add Modules' option.

I think that the problem might be connected with the type of Disk Volume. Catalina uses APFS and it might be not acceptable for some versions of Unity. I installed Unity on another disk (partition) that has volume format - "Mac OS X Extended Journaled". You can create this another partition using Disk Utility.

Open Disk Utility
You should see all availible disks
Choos Volume you would like to split
Choose "Partition" and it will show a message that "APFS volumes share storage within a container" -> but still choose Partition.
Hit + and decide how many GB you would like to split.
Choose a format - Mac OS X Extended Journaled and hit apply.
And then you should be able to use this disk in order to install Unity.

Your answer is very helpful. I downgraded my $$anonymous$$ac OX to 10.11 which uses "$$anonymous$$ac OS X Extended Journaled" partition and I no longer encounter any installation problems.

I had the same problem and solved it by installing unity using homebrew as follows: https://github.com/wooga/homebrew-unityversions

You can download and install old version unity from unity hub by MacOS Big Sur.

Click the Add button, click the Archive Download link, and select the version of Unity's Unity Hub(Green Button) you want to install.
