Errno13 when installing Fusion 360 on Mac

[heliyuan.2004]

I encountered "[Errno 13] Permission denied" when installing Fusion 360 on Mac (with M1 chips and macOS 12). I have tried the solutions on the relevant troubleshooting page, including restarting and disabling the anti-virus software. However, it still failed and I got the same Errno message each time. Attached is the log. I would appreciate it if you can do me the favor.

Hi @heliyuan.2004 

Try to change the permission settings via Terminal. 

1. Open terminal. 
2. Switch to root user with the sudo command: ’sudo -i'
   • Note: This requires the admin password
3. Navigate to the user’s application support library. In terminal, type cd /Users/<username>/Library/Application Support/‘
4. Change permissions for the Autodesk folder and its contents inside Application Support to read, write, and execute using chmod command: 'chmod -R 777 Autodesk/‘
5. Check ownership of /Users/<username>/Applications folder, if the folder is owned by root, grant logged in user and others full access rights to the folder using the command: 'chmod -R 777 ~/Applications'
6. Finally, relaunch the installer.
7. If the installer would still fail please change the ownership of the 'Applications' folder with the below command running from a Terminal (it may prompt for password input) then do the install:

           sudo chown <username> ~/Applications
