Feb 12, 2018 I can't seem to get the icon of any aliases to change in macOS Sierra. I open a PNG image in Preview, select all and copy. I then do a 'Get Info' on an alias, select the icon in the top left corner, and then paste the copied image. The icon for the alias doesn't change, but the file size of the alias does change. In iOS 10.3, Apple launches a cool function so that developers are able to programmatically change the app icon. In Apple's UIApplication API document, there are 3 things worth a glance: //A Boolean value indicating whether the app is allowed to change its icon. To make it true, we.
Apple announced macOS Big Sur last month with a redesigned interface, including new icons for nearly all the system’s native apps. And if you don’t like to have new icons mixed with old ones, you can now replace them with a more appropriate version.
Third-party apps are only expected to have their icons updated following the new guidelines later this year with the public release of macOS Big Sur, but that doesn’t mean you’ll have to wait months to get a more consistent experience with the icons.
Designer Stijn de Vries has created a custom icon pack for some popular macOS apps like Twitter, Pages, Keynote, and Visual Studio Code. These custom icons follow the same style as the new icons from Apple that are present in macOS Big Sur, with shadows and 3D effects.
According to Stijn in a comment on Reddit, more icons will be added in the future. It’s also interesting to note that Pages and Keynote icons, specifically, are official Apple icons shown in promotional images of macOS Big Sur. You can download Stijin’s custom icons here.
Twitter user @basvanderploeg has also shared his own pack with custom icons for Slack, Sketch, Skype, Telegram, Tweetbot, and more. These icons are available for free here on this website.

In order to add custom icons in the apps installed on your Mac, you have to manually replace them. If you don’t know how to do this, you can follow our tutorial on how to change app icons in macOS.
These custom icons are quite elegant and they’ll certainly make your Dock more consistent until apps get updated with new official icons. What do you think about the icons? Let us know in the comments below.

App Icon
Beautiful, compelling icons are a fundamental part of the macOS user experience. Far from being merely decorative, icons play an essential role in communicating with users. To look at home in macOS, an app icon should be meticulously designed, informative, and aesthetically pleasing. It should convey the main purpose of the app and hint at the user experience.
Consider giving your app icon a realistic, unique shape. In macOS, app icons can have the shape of the objects they depict. A unique outline focuses attention on the object and makes it easy to recognize the icon at a glance. If necessary, you can use a circular shape to encapsulate a set of images. Avoid using the rounded rectangle shape that people associate with iOS app icons.
Design a recognizable icon. People shouldn’t have to analyze the icon to figure out what it represents. For example, the Mail app icon uses a stamp, which is universally associated with mail. Take time to design an engaging abstract icon that artistically represents your app’s purpose.
Embrace simplicity. Find a single element that captures the essence of your app and express that element in a simple, unique shape. Add details cautiously. If an icon’s content or shape is overly complex, the details can be hard to discern, especially at smaller sizes.
Provide a single focus point. Design an icon with a single, centered point that immediately captures attention and clearly identifies your app.
iOS icons
macOS icons
If you’re creating a macOS version of an iOS app, design a new version of your app icon. Your macOS app icon should be recognizable, but not an exact copy of your iOS app icon. In particular, the macOS icon shouldn’t use the same rounded rectangle shape that the iOS icon uses. App Store, Maps, Notes, and Reminders provide icons for macOS and iOS that are recognizable, yet distinct from one another. Reexamine the way you use images and metaphors in your iOS app icon. For example, if the iOS app icon shows a tree inside the rectangle, consider using the tree itself for your macOS app icon.
Use color judiciously. Don’t add color just to make the icon brighter. Also, smooth gradients typically work better than sharp delineations of color.
Avoid mixing actual text, fake text, and wavy lines that suggest text. If you want text in your icon but you don’t want to draw attention to the words, start with actual text and make it hard to read by shrinking it. This technique also results in sharper details on high-resolution displays. If your app is localized, prefer fake text or wavy lines over actual text in a specific language.
Avoid including photos, screenshots, or interface elements. Photographic details can be very hard to see at small sizes. Screenshots are too complex for an app icon and don’t generally help communicate your app’s purpose. Interface elements in an icon are misleading and confusing. If you want to base your icon on photos, screenshots, or interface elements, design idealized versions that emphasize specific details you want people to notice.
Don’t use replicas of Apple hardware products. Apple products are copyrighted and can’t be reproduced in your icons or images. In general, avoid displaying replicas of devices, because hardware designs tend to change frequently and can make your icon look dated.
Perspective and Textures
Design an icon with appropriate perspective and a realistic drop shadow. In general, an app icon should depict an object as if viewed through an imaginary camera that’s facing the object, positioned just below center, and tilted slightly upward. This camera should be positioned far enough away that the icon is nearly isometric, without appearing distorted. To achieve a realistic drop shadow, imagine a light source that’s also facing the object, but is positioned just above center and tilted slightly downward.
Rotation
Consider tilting your icon after rendering it. A small amount of rotation can help people distinguish your app icon from documents and folders. A rotation of 9 degrees tends to work well.
Use only black in your icon’s drop shadow. In some contexts, such as Cover Flow view mode in Finder, app icons are displayed against a dark background. If an icon’s drop shadow uses colors other than black, the drop shadow can appear more like a glow.

Portray real objects accurately. Icons that represent real objects should look like they’re made of real materials and have real mass. Realistic icons should accurately replicate the characteristics of substances like fabric, glass, paper, and metal in order to convey an object’s weight and feel. For example, the Preview app icon incorporates glass effectively in its magnification tool.
Consider adding a slight glow just inside the edges of your icon. If your app icon includes a dark reflective surface, such as glass or metal, add an inner glow to make the icon stand out and prevent it from appearing to dissolve into dark backgrounds.
App Icon Attributes
All app icons should adhere to the following specifications.
| Attribute | Value |
|---|---|
| Format | PNG |
| Color space | sRGB |
| Layers | Flattened with transparency as appropriate |
| Resolution | @1x and @2x (see Image Size and Resolution) |
| Shape | Square canvas; allow transparency to define the icon shape |

Don't provide app icons in ICNS or JPEG format. Add de-interlaced PNG files in the app icon fields of your Xcode project's asset catalog.
App Icon Sizes
Your app icon is displayed in many places, including in Finder, the Dock, Launchpad, and the App Store. To ensure that your app icon looks great everywhere people see it, provide it in the following sizes.
| Icon size (@1x) | Icon size (@2x) |
|---|---|
| 512px × 512px (512pt × 512pt @1x) | 1024px × 1024px (512pt × 512pt @2x) |
| 256px × 256px (256pt × 256pt @1x) | 512px × 512px (256pt × 256pt @2x) |
| 128px × 128px (128pt × 128pt @1x) | 256px × 256px (128pt × 128pt @2x) |
| 32px × 32px (32pt × 32pt @1x) | 64px × 64px (32pt × 32pt @2x) |
| 16px × 16px (16pt × 16pt @1x) | 32px × 32px (16pt × 16pt @2x) |
Simplify your icon at smaller sizes. There are fewer pixels to draw as icon size decreases. In your smaller icons, remove unnecessary features and exaggerate primary features so they remain clear. Even when a high-resolution size matches the pixel dimensions of a standard size, you should still consider simplifying the smaller rendered image. For example, the 128pt × 128pt @2x icon appears smaller onscreen than the 256pt × 256pt @1x icon, even though both icons have the same number of pixels. Visually smaller icons shouldn't appear drastically different from their larger counterparts, however. Any variation should be subtle so the icon remains visually consistent when displayed in different environments.
Keep high-resolution and standard-resolution artwork consistent. For example, the 256pt × 256pt @1x and 256pt × 256pt @2x images should look the same. Some people use multiple displays with different resolutions. When they drag your icon between their displays, the icon's appearance shouldn’t suddenly change.
