This is my first time downloading unity and I am a school student who is trying learn multiple programming languages. I get this error when I install Unity editor and select Unity-2022-3-LTS.4f1 silicon LTS:

Install failed: permission denied, mkdir ‘/Applications/Unity’.

I am on mac, not an administrator have already check ‘read & write’ permissions… and nothing works for me.

By default when you download UnityHub.dmg it installs itself to Admin Applications directory. Where it can't really make changes... I installed the Hub to my users/Applications directory and then it worked like charm.

Have you tried installing the Unity editor to a different folder, like your user folder? To do this, in the Unity Hub, select “Install” for the desired version of the editor, then click “Change Location” to select a different installation folder.

Hello, for some reason I do not have the option to change location, can you help me with this?

I ran into a similar issue when returning to Unity after a few years. Check the Applications directory and delete the Unity folder if it contains older versions (before Unity Hub was released). If you still receive the error, give Unity Hub folder permissions in your System Settings.

Hey,
You must have not been an administrator, therefore, it showed access denied as you are probably a standard user with normal computer rights while the administrator has access to the whole platform and etc. If you want, you can change your account from standard to admin which would make your life easier or just reopen unity with admin (right-click and click run as administrator, not unity hub) You could also change the instances when the UAC prompt is required but the best option is that your account should be an administrator (it is not required but it’s your choice as then you would have to enter the admin account pin to do stuff that is above your access level :slight_smile: ).

I know this may be a little confusing as I am not the best explainer but tell me if any questions!

Thanks

Still struggling to do this directly. But if you’re trying to open an existing project with the missing editor, Unity Hub will let you directly install the missing editor after seeing the editors missing.

This issue arises when the user does not have permissions for the default folder for Unity Hub installs of the Editor folder within ~/Applications/Unity/Hub/ Change your user account from a Standard user to Administrator or if you know your admin username and password, you can right click on the Editor folder, right click on it and pick Get Info, make sure that Sharing & Preferences is expanded. Click on your username, and then under Privilege, change it from "Read Only" to "Read & Write". When you do that it will ask for any Admin username and password. Enter them. Your done!
