How to install applications in MacOS running on M1 or M2 Chips

Installing applications on macOS M1 or M2 is a straightforward process, and it’s no different on Macs powered by the M2 chip. The M1 and M2 chips are designed to run macOS efficiently and offer an excellent user experience. Here’s a step-by-step guide on how to install applications on a Mac with an M2 chip:

MacOS App Store

The App Store is the official marketplace for macOS applications. It’s the easiest and safest way to install software on your Mac. Follow these steps to install an app from the App Store:

• Open the App Store from your Dock or use Spotlight Search (Command + Space, then type “App Store”).
• Browse or search for the application you want to install.
• Click on the app’s icon to view more details.
• Click the “Get” button to download and install the app.
• You might be prompted to enter your Apple ID credentials or use Touch ID/Face ID for authentication.

Finder:

You can also install applications downloaded from the internet or copied from external sources. To do this:

• Open the Finder from the Dock.
• Navigate to the folder containing the application or its installer file (usually ending with .dmg or .pkg).
• Double-click on the file to open it.
• If it’s a .dmg file, you’ll see a window with the app icon. Drag the app icon to the Applications folder to install it.
• If it’s a .pkg file, follow the on-screen instructions to complete the installation.

Third-Party App Stores:

Some applications might not be available on the official App Store but can be downloaded from third-party app stores or developer websites. Be cautious when downloading from these sources, as it’s essential to ensure the software is from a reputable source. To install apps from such sources:

• Download the application from the source’s website.
• Open the downloaded file.
• Drag and drop the app into the Applications folder or follow any specific installation instructions provided.
• 

• Open Terminal (found in the Utilities folder within Applications or search for it using Spotlight).
• Run the following command to install Homebrew:
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
• Follow the on-screen instructions to complete the installation. After installing Homebrew, you can use it to install various command-line and GUI applications. For example, to install a package like “wget,” you would use the following command:

   brew install wget

Mac App Installers:

Some applications come with their own installers. These typically include a .pkg file that guides you through the installation process. To install such apps:

• Download the application installer from the developer’s website.
• Open the downloaded file and follow the on-screen instructions.

Gatekeeper and Security:

macOS has a security feature called Gatekeeper that restricts which apps can be installed. It’s recommended to keep Gatekeeper enabled to protect your Mac from malicious software. However, if you encounter issues installing an app that you trust, you can adjust Gatekeeper settings. To do this:

• Go to “System Preferences” > “Security & Privacy.”
• Under the “General” tab, you may see a message stating that an app was blocked from opening. Click “Open Anyway” to allow the app to run.
• You can also adjust Gatekeeper settings in the “Security & Privacy” preferences to allow apps from identified developers or anywhere. Be cautious when changing these settings, as it can compromise your system’s security.

Updates:

After you’ve installed applications, it’s essential to keep them up to date. Regularly check for updates in the App Store, or many apps have built-in update mechanisms. Staying up-to-date ensures that you have the latest features and security patches.

In summary, installing applications on a Mac with an M2 chip is a straightforward process. You can use the App Store for officially approved apps, download from the internet or third-party sources with caution, and use package managers like Homebrew for command-line tools. Remember to keep your Mac’s security features, like Gatekeeper, enabled, and regularly update your installed applications for the best performance and security.
