The closest Mac equivalent is the Recent Items list.
The Recent Items list resides under the Apple menu and dynamically lists the applications, documents, and servers you have used, opened, or connected to recently. This list is updated every time you launch an application, peruse a document, or connect to a server. It is not a list of frequently used items, but recently used items, a subtle but not unimportant distinction. To view the Recent Items list, click the Apple menu the Apple icon in the top left corner of the display , and select Recent Items.
The Recent Items menu will expand to reveal all recently used applications, documents, and servers.
Find the Absolute Path to a folder or directory in Mac OS X
Select the item you wish to access from the list. The Windows Start menu includes an All apps menu All Programs in older versions of Windows that can display all of the applications installed on your Windows PC in a list. Launchpad is the closest equivalent on the Mac. Launchpad is based on the popular application launcher used in iOS devices, such as the iPhone and iPad. When you use it, Launchpad replaces the Desktop with an overlay of large icons for each application installed on your Mac.
Launchpad can display multiple pages of applications, which you can then drag the application icons around, put them in folders, or otherwise rearrange them however you like. Clicking on one of the application icons will launch the associated program. You'll find Launchpad located in the Dock, most likely as the second icon from the left. We say "most likely" because you may have already tinkered with the Dock after reading the above information. Don't worry if you deleted the Launchpad icon from the Dock, you can drag it from the Applications folder and drop it back onto the Dock if you wish to use it as your primary program launcher.
The other method of accessing all programs on a Mac, regardless of the version of OS X or macOS you're using, is to go directly to the Applications folder. Under Windows, programs are generally stored in the Program Files directory in the root of the C: drive. While you can launch applications by looking through the Program Files directory, and then finding and double-clicking the appropriate. On the Mac, the equivalent location is the Applications folder, also found in the root directory of the Mac's startup drive loosely equivalent to the Windows C: drive.
Unlike the Program Files directory, the Applications folder is a simple place from which to access and launch applications. For the most part, applications on the Mac are self-contained packages that appear to the casual user as a single file. Double-clicking the application file launches the program.
This self-contained structure makes it easy to drag a program from the Applications folder to the Dock when you want to have easier access to the application. It also makes it easy to uninstall an application, but that's another chapter. From the Finder's Go menu, select Applications. From here you can scroll through the list of installed applications, launch an application by double-clicking its icon, or drag an application's icon to the Dock for easier future access.
A few paragraphs back we mentioned that one of the functions of the Dock is to show which applications are currently running. If you launch an application that isn't in the Dock, say from the Applications folder or the Recent Items list, the OS will add the application's icon to the Dock. Now that you can select a folder, your next job is to find the contents of that folder and display it. The previous section of code populated a property named selectedFolder.
Scroll to the top of the ViewController definition and check out the selectedFolder property. The key line here is the one that calls contentsOf folder:. Scroll down to the stub of this method, which is currently returning an empty array. Replace the entire function with the following:.
The selectedFolder property sets the filesList property to the contents of the selected folder, but since you use a table view to show the contents, you need to define how to display each item. You need to change that before anything will appear in the table. Now build and run, select a folder and you should see a list of files and folders appear — hurray! Open up the Finder and press Command-I to open a window with information about the file: creation date, modification date, size, permissions and so on.
All that information, and more, is available to you through the FileManager class. Back in the app, still in ViewController. This sets the property of the ViewController : selectedItem. Scroll back to the top and look at where selectedItem is defined. As with selectedFolder , a didSet observer is watching for changes to this property. When the property changes, and if the new value is not nil , the observer calls infoAbout url:. This is where you will retrieve the information for display.
Find infoAbout , which currently returns a boring static string, and replace it with the following:. In Unix systems, files and folders whose name starts with a period are invisible.

Go to contentsOf folder: and replace the line containing map with the following:. The above adds a filter that rejects hidden items if the showInvisibles property is not true. Otherwise the filter returns every item, including hidden items. Find the toggleShowInvisibles method of ViewController and insert this into the function:. Build and run, select a folder and check and un-check the Show Invisible Files button.
In the storyboard, the table view has been assigned a doubleAction that calls tableViewDoubleClicked. Find tableViewDoubleClicked and replace it with the following:.

Build and run, select a folder containing other folders, and then double-click a folder in the list to drill down into it. Once you have implemented double-click to drill down, the next obvious step is to move back up the tree. This first checks to see whether the selectedFolder is the root folder.

Editing selectedFolder will trigger the update as before. Build and run again; confirm that you can select a folder, double-click to move down into a sub-folder and click Move Up to go back up the folder hierarchy. You can move up even before double-clicking a folder, as long as you are not already at the root level.

There are two main ways to save data: user-initiated saves and automatic saves. For user-initiated saves, your app should prompt the user for a location to save the data, then write the data to that location. For automatic saves, the app has to figure out where to save the data. In this section, you are going to handle the case when the user clicks the Save Info button to initiate a save.
You used NSOpenPanel to prompt the user to select a folder. This time, you are going to use NSSavePanel. The encoding for the text in this file is set to UTF8 , which is a commonly used standard. Build and run, select a file or folder from the table and click Save Info. Select a save location, and click Save. If you continue to browse, we will assume you are happy with it. Read more.
