How to Install and Uninstall Software on a Mac

  • MORE


If you've ever come across a great deal on Mac software on the Web, you might feel frustrated once you have it—how do you install it? But, one of the best things about using a Mac is how easy it is to install software. And removing most software packages on macOS is just as easy.

Macintosh computers use a disk image or .dmg files for installing software. Sometimes you will come across a package or .pkg file, and sometimes these files are compressed into a Zip file (.zip). And all applications are stored in the Applications folder.

How to Install Mac Software

1. Double-click the application file you've downloaded from the Internet. If you get an error message that says the program "can't be opened because it wasn't downloaded from the Mac App Store," right-click the downloaded file and select Open. 

Mac installation files are named .dmg, .pkg, or .zip. If it’s a zip file, this will unpack the zip automatically into its own folder. If it’s not a zip file, skip to the next step. Once the zip file has been unpacked, navigate to that folder, where you will find a .dmg or .pkg file.

    I'm researching Apple products (impressed with the 13" Air) but mostly focusing on the Operating System. Installing and uninstalling apps are one of the key (headaches) aspects of a modern OS (it's a shame that something as simple as uninstalling an app can cause the OS and its' user so much grief).

    For some of us looking to switch over from Windows and the constant hunting for program breadcrumbs (registry, odd folder locations spread anywhere on the system), how does Mac OS handle this?

    From what I've read elsewhere, the uninstall method isn't 100% effective. There might be a few places (not many) where one needs to look to erase all setting/config and other program left-overs.
