Switched from Windows to a Mac and getting to grips with the basics ? Wondering how to install software on your MacBook from the command line? Got an old Windows app that you simply must run on your new Apple computer?
Your Mac’s operating system operates quite differently to its Windows counterpart. There’s no central registry, quite often no installer files, and uninstallers are a lot less common on the platform than they are on Windows.
So here’s what you need to know about adding or removing software on your Mac.
Installing from Mac App Store
Suitable for: Common apps that can use the platform’s marketplace to install updates, but many software packages are often missing. You should also avoid buying games from the Mac App Store , particularly multiplayer ones.
App stores are probably the easiest way to install software on any platform, whether it’s your iPhone or Windows 10. The main drawback is that many common apps are missing from the store , and that apps listed must conform to Apple’s sandboxing rules which restrict what developers can do. That also means this is probably the safest source of third party software.
You’ll need to login to the Mac App Store before you can use it, simply launch it, then click Store and Sign in using your Apple ID. To install apps from the Mac App Store:
- Launch the Mac App Store app and find the app you want by browsing the relevant tabs, or searching for it.
- Choose an app and click Install, then enter your Apple ID password to verify your identity.
- Wait for the app to download and install, then launch it by clicking Launch, searching Spotlight, or finding it in your Applications folder.
To remove an app you’ve installed this way, launch Finder and navigate to your Applications folder. Drag the app’s icon to the Trash bin to remove it. Any apps you’ve downloaded in the past (free or paid) can be re-downloaded under the Purchased tab.
Drag & Drop Installs
Suitable for: Apps you’ve downloaded from the Internet as .DMG, .ZIP or .APP files.
If you’re downloading an app from somewhere other than Apple’s marketplace, there’s a good chance you will be downloading a .DMG file. These are disc images, which you must double-click to mount like a DVD or USB drive. They’ll then appear in your Finder sidebar under Devices.
You may also download .ZIP archives, which you’ll need to extract first by double-clicking on them. Sometimes websites will simply download the .APP file. To install these apps:
- First mount your .DMG and open the device in Finder, unzip your .ZIP, or and find your .APP file.
- Drag your .APP file (the app’s icon) into the Applications folder in Finder.
- You may need to provide an admin password for apps that require additional privileges.
- Launch the app via Spotlight (command+spacebar) or by finding it in your Applications folder.
You can drag the app icon to the Trash to remove the app.
Suitable for: Windows-like app installers bundled as .PKG files.
Sometimes you’ll need to install software using an installer, bundled as a .PKG file. This is just like installing software on Windows, where the installer will usually provide a few options to choose from, and often require an admin password to make changes to your system. To install a .PKG, simply double-click it and follow the instructions.
While you can often drag the app icon to the Trash like any other, apps installed via this method sometimes have packaged uninstallers or apps. You may also need to supply an admin password to make changes to certain parts of your system.
Suitable for: Common apps that are available through central repositories, users who value fast installs and the efficiency of a command line experience .
You can access your Mac’s command line with a bundled app called Terminal, found in the Applications > Utilities folder or by searching Spotlight. It’s also possible to install software via this method, which is much quicker than finding software, unpacking it, and dragging icons into folders.
To make this simple, you’ll need a package manager called Homebrew:
- Head to the Homebrew website and copying the command listed underneath “Install Homebrew.”
- Launch Terminal and paste the command followed by Enter.
- Your Mac will install Homebrew, and prompt you to install any additional packages you may need.
- Once installed you can use the
brewcommand in Terminal to install software, e.g.
brew install firefox
Once installed you can use the command line to install a variety of common free apps like Dropbox, VLC, Transmission and many more. Check out our previous article covering Homebrew and what it can do .
Installing Windows or DOS Software
Suitable for: Windows software you simply can’t live without, old games, and any non-native apps you want to run on your Mac.
There are two ways to run Windows software on Apple hardware, where no native Mac version exists. The first is using a compatibility layer called Wine . This software allows you to install and run Windows software on Mac and Linux as if you were running Windows. Unfortunately, it’s not the most reliable of solutions, but as there’s no emulation taking place it’s a relatively fast way of doing so.
The other way of doing this is using virtualization, where you use software to emulate a Windows PC and run Windows on top of OS X. While this will provide the most stable performance (the software is after all running on its intended OS), it’s a resource-hog that requires lots of free memory and processing power. You also may run into problems with drivers and 3D acceleration.
We’ve previously covered this in an article about running Windows and DOS games on your Mac , but the guide applies as much to regular software as it does to Age of Empires II. Everything you need is covered under the Virtualization and Wine sections.
If possible, it might be worth finding yourself a native app to do the job instead. You’ll experience faster performance and greater stability.
Running Software & GateKeeper
GateKeeper is Apple’s answer to the growing problem of Mac malware. It’s a security feature that stops your Mac from running software installed from simply anywhere. By default, your Mac will only allow you to run apps from trusted developers and the Mac App Store, but many apps that don’t fall under this remit are legitimate and pose no risk to your machine.
You can change your GateKeeper settings under System Preferences > Security> General. You’ll need to click the lock icon and enter an admin password to make changes, but you’ll be able to disable the feature in order to allow software from anywhere to run.
An alternative option is to allow apps to run on a case-by-case basis, which removes the need to disable the feature completely. After you run an app that’s been denied by GateKeeper, head straight to System Preferences > Security > General where your Mac will report it denied an app from running. You can then click the Open Anyway button to create an exception for that particular app, which will allow it to run in future.
As noted in most of these install methods, the easiest way to remove software usually involves finding the app in your Applications folder and dragging the icon to the Trash bin. You might also find an uninstaller package too.
But a more thorough and convenient way of uninstalling files is using a free app called AppCleaner. It allows you to bulk-remove applications, which means you can free up lots of space and clean your Applications folder out in one go. It will also go deeper than a simple drag-and-drop, and try and remove other files associated with apps that you no longer want.
It’s so thorough it can even reset shareware trials, but you didn’t hear that from us. Check out our guide to uninstalling just about everything from your Mac .
