Like Windows PCs, Macintosh computers use virtual memory to run more programs than the system memory normally could accommodate. A Mac uses a swap file to temporarily store applications and program components that it does not need at the moment. When it needs something from the swap file, it retrieves it and reloads it into RAM. Sep 21, 2020 RAM (Random access memory) is one of the biggest contributing factors to a computer’s performance. Without sufficient RAM, applications or programs don’t work as intended, perform slower, and can even crash in the middle of your work if the available memory is critically low. A good practice is to allocate more RAM to a program.
The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
