When I change any file, the system will deny me access. What\'s going on? How do I properly set permissions on Mac?
I had a similar issue. I had error when I tried to create a new component. I just navigated to the path displayed in Finder. For me it was ProjectFolder/src/. So I did right click on "src" folder and selected "Get Info". In that change access to "Read&Write" for my user account. Thats it !!!
As you are trying to update a file, try to change access permission for that file (ie. app.component.css). If it didn't work try to change access for "app" folder.
Note: Changing the access of parent/super-parent folder won't work. So change the exact folder's access preferences.
