Permissions in OSX

Using Glyphs 2.0.1 (744) I get the following error

The document “Vivid -Regular.glyphs” could not be saved as “Vivid -Regular”. You don’t have permission.

Any advise how to fix it in Mac OSX

Right-click on the directory you’re trying to save to and choose “Get Info”. Under sharing and permissions make sure that you have read and write access. If this happened out of nowhere you probably need to close everything running on your Mac and then open Disk Utility and run “Repair Permissions” on your hard drive. Then reboot.

Many thanks
I think that has worked.
