How to Download & Install Apps on Mac not from App Store Safely

Installing macOS apps outside the App Store: A comprehensive guide

The macOS App Store offers a convenient and secure way to install applications. However, some apps aren't available there, or you might prefer downloading directly from the developer's website. This guide explains how to safely install and manage apps obtained outside the App Store, emphasizing security best practices.

Downloading and Installing Apps

Apple's App Store guidelines ensure app quality and user safety. Apps not meeting these criteria, or those developers choose not to list, are still accessible via their official websites or other reputable sources. Popular examples include VLC, GrandPerspective, Audacity, and OpenEmu.

Installing a non-App Store app is generally straightforward. Most involve dragging the app or folder to your Applications folder. However, some may use installers (PKG files).

Here's a step-by-step guide:

1. Download the app from a trusted source (official website preferred).
2. Scan the downloaded file for malware using a reputable antivirus program (MacKeeper is mentioned in the original, but any reputable program will do).
3. If it's a zip file, double-click to extract. DMG files mount automatically in Finder; drag the app to the Applications folder.
4. For PKG installers, double-click to run the installation process.

Enabling Non-App Store Apps

macOS's Gatekeeper security feature prevents unverified apps from running unless explicitly allowed. While the "Anywhere" option in older macOS versions (pre-Ventura) directly enabled this, Ventura requires using Terminal:

1. Close System Settings if open.
2. Open Terminal (Applications > Utilities > Terminal).
3. Type sudo spctl --master-disable and press Return.
4. Enter your administrator password.
5. Re-open System Settings and select "Anywhere" under "Allow applications downloaded from."

Opening Blocked Apps

Even with Gatekeeper restrictions, individual apps can be run. macOS might prompt confirmation; if not, follow these steps:

1. Double-click the app. If prompted "Are you sure you want to open it?", click "Open."
2. If blocked, cancel and go to System Settings > Privacy & Security. Find the blocked app message, click "Open Anyway," and enter your password.
3. Alternatively, right-click the app and select "Open." You'll see the same confirmation prompt.

Uninstalling Apps

Uninstalling apps (App Store or otherwise) is similar. Apps with uninstallers should use them. Otherwise, drag the app from the Applications folder to the Trash and empty it. However, remnants may remain. A dedicated uninstaller tool (like MacKeeper's Smart Uninstaller) can help remove these completely.

Safety Precautions

While convenient, installing apps outside the App Store carries risks. Always download from official websites, scan downloads with antivirus software, and use a dedicated uninstaller to prevent leftover files. Prioritize App Store downloads whenever possible.
