I would like to disable inline attachment previews by default, and instead view all attachments as icons in Mac's Mail app in macOS Mojave. In High Sierra, the following terminal command was sufficient: defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes. However this command does not work in Mojave. Mar 23, 2020 The Apple Icon Image format supports a wide variety of icon types ranging from tiny 16-by-16-pixel icons to the 1024-by-1024 ones for Retina-equipped Macs.ICNS files are a handy way to store and distribute Mac icons, but their one downside is that the method of copying an image from the ICNS file to a folder or drive is slightly different from the usual process and not as well-known. Literally any image can be pasted as an icon. Been that way since MacOS 8(?). Although in the pre-OSX days it needed to be a certain size. You only need to create a.icns file if the icon you want to replace is an app that uses widgets on top of the icon when its running. Otherwise, just paste away.

The App Store has changed look, but not functionality; you can still visit to search for and find Apps for your Mac. Now, it is a bit easier to find what you are looking for, and has a new style. From the Apple menu, select App Store. When you first launch the App Store, a brief explanation of how it works is displayed. Select Continue. A common complaint from Mojave users is that when you copy and paste a file icon to create a custom icon for a file or folder, the result is blurry. It turns out that this only happens when the icon image is not square. Convert the image to a square one, or copy a square portion of.
Certain actions that you perform on your Mac will cause default apps to open. For example, clicking a document may open Pages. But what if you want Microsoft Word to open instead? You can also set your default web browser and email reader.
Here's how!

- Right-click on a file that uses the file type you'd like to change the default for. For example, one with a .jpg extension (a photo).

Now any time you open a file with that extension, the Finder will automatically open it with the app you've selected.
