After a few hours of work, a Finder window in icon mode can look something like a teenager’s room: stuff strewn all over the place, as demonstrated with the Applications folder in Figure 1.

You can set the application dock icon while your application is running, see com.apple.eawt.Application.setDockIconImage. It isn't perfect though, because when you double-click on your jar, it starts up in the dock using the generic java icon and only switches to your custom icon after a bounce or two when the java code starts running. Changing your app icons is not only fun, but in some cases you just have to do it to enjoy using your Mac. We’ll talk more about that below. Why to change an app’s icon. Changing an app’s icon does nothing functionally, but it does change the aesthetic of the app’s icon, which means you get to look at something different.
Ipad app to control mac. To restore order to your Desktop, click in any open area of the active window and then choose View –> Clean Up. This command leaves the icons in approximately the same position but snaps them to an invisible grid so that they’re aligned, as shown in Figure 2.
To replace the generic dock icons with the actual application icon, here's what I did: Right click on the generic dock icon; Choose Remove from Dock; Open the application from the Applications Folder in Finder; Drag the application back to the Dock; The new dock icon should be the proper one. Is the application icon completely missing (leaving a blank space where an icon might appear), or is the icon just a generic icon (not the custom icon that you would expect to see) Have you tried a logout from your user - or simply restarted your Mac?

After things are in alignment, work with the icon view options. (Naturally, you’ll want the active Finder window in icon view first, so choose View –> As Icons or press COMMAND+1.) From the Finder menu, choose View –> Show View Options — or press that swingin’ COMMAND+J shortcut — to display the View Options dialog box that you see in Figure 3. (Remember that these options are the ones available for icon view.)

Note these first two radio buttons, which also appear in the list View Options dialog box:
For example, any changes made to the settings in Figure 3 will affect only the Applications folder because it was the active Finder window when you pressed COMMAND+ J. (You may have noticed that the window name also appears as the title of the View Options dialog box.)
Of course, Mac OS X remembers the changes that you make within the View Options dialog box, no matter which view mode you’re configuring. You can also make other changes from this dialog box, including
• White: This is the default.
• Color: Click a color choice from the color block that appears if you make this selection.
• Picture: Select this radio button and then click the Select button to display a standard Open dialog box. Navigate to the location where the desired image is stored, click it once to select it, and then click Open.
After all your changes are made and you’re ready to return to work, click the dialog box’s Close button to save your settings.
Design and implement macOS document icons
September 9, 2020
A good document icon aids in the identification of your file on the Desktop, in a Finder window, or in an open dialog, especially when previews aren’t available. These icons may be displayed on screen as small as 16pt or large enough to showcase every glorious design detail.
Depending on the file type and personal preference, document icons can also display document previews. If someone has chosen not to show document extensions in System Preferences, these icons can additionally provide additional context in deciphering their file type and native program.
With macOS Big Sur, you can customize and control how your app’s document icons display across the system. We’ll show you how to design a great icon, integrate it into your Xcode project, and assign document types and type identifiers.
Design a document icon for your app
By default, if you don’t specify a document icon for a file type in your app, macOS will automatically create one for you by compositing your app’s icon together with the correct extension name. This is a common pattern for imported document types or non-proprietary file formats that your application can open such as MP3, JPG or PNG.
Both the Music and Preview apps use system-generated document icons for document types like JPG and MP3.
You can additionally create a custom document icon if your app supports multiple file types and you’d like to visually distinguish between them. For example, a drawing application may open a jpg file, a project file, a library of drawing components, a plugin or a color swatch.
When creating a custom icon, we recommend keeping its design simple. Try to depict what your icon represents as closely as possible and with as few details as possible. Additionally, think of other document types that your document may commonly be next to, and use distinct shapes and colors that are identifiable even at smaller sizes.
Best apps for mac college students. If you plan to create multiple custom icons for different file types, it’s important to make each design distinct and understandable to help people know what to expect when they open them.
The elements of a custom document iconBeginning with macOS Big Sur, you can generate a new custom document icon with a set of images and a text string.
To create a new custom document icon, you can provide a background fill, center image, or text string. Each of these three elements is optional, allowing you to use just one element or any combination of the three to customize your icon. From there, macOS will automatically layer, position, and mask these elements, then composite them into a page icon with a right corner fold.
You can download Sketch and Photoshop templates on Apple Design Resources to assist in the generation of the image assets in all their required sizes.
Fill in the backgroundThe background image allows you to customize the background of your icon. The art should fill the entire drawing area, as shown below, and the system will automatically mask it to the document shape in all sizes.
Background images can not only be used to change the background of your document, but you can also use them to create custom designs that fill the entire page.
The background image should be drawn in the following sizes:
The Xcode Project icon and the Rich Text Format icons use nothing but the background fill element to create a custom look and feel.
Add a center imageThe center image is always half the size of the document canvas. For example, the center image displays at 16pt on a 32pt icon size.
The bulk of the artwork for the center image should be drawn at ~80% of the canvas size. For example, on the 256x256 version, the drawing should be inside a 205x205 area, as shown in the image below. Curves and points can extend into the margin to adjust for optical alignment.

The shape of the artwork should be simple to make it easily identifiable in smaller sizes. The rendering, however, can be as simple or as rich as you’d like.
The center image can be specified in the following sizes:
Add some textual contextThe icon’s text string will often be your document’s extension, but can also be something more descriptive. For example, 'SCENE' is more descriptive — and easier for someone to understand — than 'scn.'
The Swift and Metal document icons both use text strings to clearly identify their document types.
The system will capitalize and scale the text to fit inside the icon, so it’s important to keep the length of your string as short of possible to prevent it from getting too small. The text will also automatically change its color to remain legible against flat colored backgrounds.
Build document icons in your app
To create your document icon types, you’ll need to integrate these elements into your Xcode project.
Bring images into the asset catalogFirst, add your background fill image and/or center image into the Asset Catalog as Generic Icons.
If your assets are named using the format icon_[size]x[size][@resolution].png (e.g. [email protected] or icon_32x32.png), they can all be dragged at once and will automatically be assigned to their appropriate size slots.
