Problem getting Unity running.

Just downloaded the new version, and started the setup. Entered account info, and then I get this error message:

“Failed to write “/Library/Application Support/Unity/Unity_v5.x.ulf”. Please verify you have write permissions to this file.”

I’m using OSX (10.10.2) and logged in as the admin. Double checked permissions for the Unity app, and it’s on Read & Write. I press OK, which leaves me at the Start Using Unity screen. I click the button, and Unity quits. What can I do?

I found a quick fix for the problem. Get into Terminal application. Use cd to get to the /Library/Application Support/. You need Admin privilege. sudo chmod 0777 Unity. That fixed the problem for me.

I had the
“Failed to write “/Library/Application Support/Unity/Unity_v5.x.ulf”. Please verify you have write permissions to this file.” error message.
What I did was

  1. Disconnect from the internet and try the manual install.

  2. After that I clicked on “Save activation code” (something like that, can’t remember exact name of the button. It downloaded a .alf file.

  3. Then I clicked on the link provided on the same Manual Install page. It brings you to a page of the unity website. Browse and select the downloaded .alf file. This provides you with a .ulf file. At first this file was automatically being converted to a .xml file since I’m on a Mac. In Finder I had to go to Finder > Preferences > Advanced and make sure “Show all file name extensions” is checked. Then make sure to delete the .xml extension. You should then be prompted to convert the file to a .ulf, do so.

  4. After this I took that file and moved it to the location: Macintosh HD (Located on Desktop) > Library > Application Support > Unity. I placed the file there and Unity started right up. Hope that helps.
