You can download and install apps from the Internet or a disc. If you no longer want an app, you can remove it. For apps downloaded from the Internet: In the Downloads folder , double-click the disk image or package file looks like an open box. Note: If you get a warning dialogue about installing an app from an unidentified developer, see Open a Mac app from an unidentified developer. Reasoning varies from a lack of deep system access for utilities to app creators wanting the ability to immediately issue updates rather than having them await Mac App Store review.
If you decide to download app installers from the Internet, only do so from reputable sources. DMG files are mountable disk images. When you double click a DMG file, a Finder window opens. DMGs may contain an installer that itself must be opened, after which point you follow on-screen instructions.
Most, though, simply contain a copy of the app. Do not run the app from inside the DMG — instead drag it to your Applications folder. A folder shortcut may be provided to make this easier. Again, drag the app to your Applications folder before opening it. Some will offer to move themselves when opened from the wrong location. PKG files are installation packages that contain scripts to direct installation, and files to be installed.
This is automated; you essentially click a few times to allow the PKG to do its thing. There are some third-party equivalents to the Mac App Store. For example type openssl sha1 R On Mac OS X Contains R 4. The latter two components are optional and can be ommitted when choosing "custom install", they are only needed if you want to use the tcltk R package or build package documentation from sources. Always re-install XQuartz when upgrading your macOS to a new major version.
