It’s time to add Electron app icons to the Electron tutorial app. For this we need a png-icon, a.icns for macs and a.ico for windows. For Linux we only need the pngs. This code is added to the Electron tutorial app on github. Have a look at that repository if you would like to see all the source code. Mac OS X: Change Which Apps Start Automatically at Login. Lowell Heddings @lowellheddings Updated July 11, 2017. To add a new application into the startup list, you can just drag and drop the icon into the list, or you can click the Plus icon and select an item using the file browser manually. It’s usually easier to just drag and drop though. Yes, you have to run the app to register the handler, and then it can be used transparently (assuming the app hides its dock icon). – iconoclast May 16 '14 at 14:16 2 @iconoclast since most applications in OS X are installed by copying, the Info.plist file is registered at time of copy (commonly to the /Appplications/Foo folder).

The following instructions for installing Ruby have been tested on Mac OS X Yosemite (10.10.4). They should work fine with Mac OS X El Capitan (10.11.1) or Mavericks (10.9.5) as long as you’re running the latest updates for that version of Mac OS X:

1Open the Applications folder, and then open the Utilities folder.

Locate the terminal program in the Utilities folder.

2Open the terminal application.

You see a prompt indicator that looks like a dollar sign ($). In the terminal application, you type commands and press the Return key to get things done. Typing commands is a low-level way of working with a computer. Before the mouse and graphical interface was invented, this was the only way to tell the computer what to do!

Note that your default prompt will include information like the name of your computer, the directory you’re in, and even who you’re logged in as:

3Mac OS X comes with a version of Ruby preinstalled; check the version by typing ruby --version at the command prompt:

In this example, the version of Ruby is 2.0.0, and the number following the letter p is the current patch or build number. Newer versions of Ruby are available, and the Mac’s version will change if you install updates.

4To use some of the Ruby gems (little add-on enhancements for Ruby), you must install Apple's command-line programming tools.

These tools are a part of the free Xcode development tools package that Apple makes available. In the terminal, enter the following command:

5Press Return.

The program will open a window to confirm you want to install the tools.

6Click the Install button, agree to the license, and wait for the tools to get set up.

This step will take a few minutes depending on the speed of your Internet connection.

7Install a set of software installation tools called Homebrew.

Homebrew makes it easy to install and update additional software, called packages. Homebrew makes it much easier to get everything working. In your browser, go to the Homebrew website.

You see instructions for installing Homebrew. The page shows a really long command that starts with ruby -e. You can copy it from the web page and paste it into your terminal window at the prompt.

This is one long line, so if something goes wrong, make sure that you got the whole thing.

The command uses Ruby to install the Homebrew tool. It displays a warning about using sudo and then asks you for your password to finish the installation.

8Proceed with the installation.

Many progress messages will fly by on your screen. If you get a message saying that you haven’t agreed to the Xcode license, follow the instructions that are displayed and continue on here.

9Once Homebrew installation is done, check that all is okay.

Variable data printing software for mac. Type the following command:

If everything is set up properly, you should see a message saying Your system is ready to brew. Otherwise, you may have some instructions to follow to finish updating Homebrew.

Homebrew’s purpose is to make installing low-level software easier.

10Install some of the libraries of code you need for future projects.

Type the following command:

11Press Return.

You see a series of progress reports as Homebrew installs the software.

12Install the Gosu gem.

Macos Change Folder Icon

Enter the following command to install Gosu:

Ruby installs the gem and should provide a confirmation message.

You need to use sudo here because when you install a Ruby gem, you install it for the entire system to use. Remember to take care when entering the command — you’re giving it special permissions using the sudo program.

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.


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.

Color spacesRGB
LayersFlattened with transparency as appropriate
Resolution@1x and @2x (see Image Size and Resolution)
ShapeSquare 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.

256px × 256px (256pt × 256pt @1x)512px × 512px (256pt × 256pt @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.
