What is ‘Get Info’ on a Mac anyway?
For those unfamiliar with “Get Info” windows in Mac OS, the feature has been around for ages since the earliest days of Mac OS, back when it was called “System”.
To access Get Info, select any item in the Finder and hit Command+i or choose “Get Info” from the File menu.
The resulting “Get Info” panel section gives you details on the file or application, the ability to change permissions, file type, properties of the item selected, and much more.
