Can you please post the permissions listed for the directory [I] /Library/Application Support/openGear/DashBoard/.metadata [/I]?
You can locate these by opening a command prompt and going to /Library/Application\ Support/openGear/DashBoard/ and doing an "ls -la" command
The DashBoard 8.0.1 installer should be leaving the owner as "root" and setting the group permissions to "staff". Once this happens, any files created should be writable by anyone in the "staff" group. Previous versions of DashBoard had the group set to "admin" which caused some issues when users were not in the "admin" group.
Once you post your permissions, if they are incorrect, I can provide you with instructions for how to fix this. If they are correct and the issue is still occurring, we will have to debug further.
