By default, your Mac's security settings only allow installations from developers registered through Apple's developer identification protocols, so most installations from the internet will cause a message like this to be displayed: 'ALL In Learning Installer.pkg' can't be opened because it is from an unidentified developer. This document describes how to enable installation/launch of applications if you encounter. By default, Mac OS 10.8.x, 10.9.x, 10.10.x, 10.11.x and macOS only allows users to install.

Apple T2 chip.The next generation of security.The Apple T2 Security Chip — included with many newer Mac models — keeps your Mac safer than ever. The Secure Enclave coprocessor in the Apple T2 chip provides the foundation for Touch ID, secure boot, and encrypted storage capabilities.
Touch ID gives you a seamless way to use your fingerprint to unlock your Mac, fill passwords in Safari, and make purchases with Apple Pay. Secure boot helps ensure that you are running trusted operating system software from Apple, while the Apple T2 chip automatically encrypts the data on your Mac. So you can be confident knowing that security has been designed right into the architecture of your Mac, from the ground up.
Protection starts at the core.The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with industry-standard antivirus software built in to block and remove malware.
Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files. Download apps safely from the Mac App Store. And the internet.Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the Store is reviewed before it’s accepted. And Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time.
If there’s ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again. Designed to protect your privacy.The most secure browser for your Mac is the one that comes with your Mac. Built-in privacy features in Safari, like Intelligent Tracking Prevention, help keep your browsing your business. Automatic strong passwords make it easy to create and use unique passwords for all the sites you visit. And iCloud Keychain syncs those passwords securely across all your devices, so you don’t have to remember them. You can also easily find and upgrade any weak passwords you’ve previously used (and reused and reused and reused). Find your missing Mac with Find My.The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad, and iPhone.
Find My can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices in use. These devices then relay the detected location of your Mac to iCloud so you can locate it in the Find My app. It’s all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage, or your privacy being compromised.
