The Mac uses these technologies to protect users when they install third-party apps:

specifically allowed. Systemwide privileges are allowed only when needed.

• App sandboxing—Apps are granted access only to the items they need.
• Code signing—Used by the system to verify the authenticity and integrity of the software.

• File quarantine—Displays a warning when you attempt to open an item downloaded from an external
source such as the Internet.

• Malware detection—macOS maintains a list of known malicious software that’s automatically updated
by the macOS software update.

• Gatekeeper—Uses both code signing and file quarantine to protect your Mac from malicious apps.
