macOS security spotlight: 3 new Tahoe features you should know

One of the advantages of using macOS is that it offers a more secure platform than Windows. Part of the reason is that it’s not targeted as often (though it has been subject to more attacks over the years), but the main reason is that Apple acts more as a gatekeeper, with security implementations within the chipset, app notarization, and many other features.

In an effort to create awareness, Apple recently met with the media to spotlight three security features introduced with macOS Tahoe. And whether you’re new to MacBook Neo or a veteran MacBook Pro user, they’ll keep you safe while you work:

FileVault recovery key in Passwords

With macOS Tahoe, Apple decided to turn on FileVault by default. FileVault is Apple technology for encrypting a Mac’s internal storage. If your Mac is lost or stolen, FileVault protects your data from unauthorized access. FileVault can be turned off in System Settings > Privacy & Security > FileVault, but you’ll be removing a significant layer of security.

To access a Mac’s internal storage when FileVault is on, you need to enter the user password for the account being used–you do that whenever you log into your Mac to use it. But what if you have an instance where you can’t remember your password? You can use a FileVault recovery key (which is generated when FileVault is turned on) when booting the Mac in recovery mode.

That FileVault recovery key used to be stored in iCloud, but with macOS Tahoe, it is now stored in the Passwords app. That means you can quickly access it in the Passwords app on you iPhone, iPad, or another Mac, provided that you sign into the same Apple Account and your devices are syncing data via iCloud.

To see your FileVault recovery key in the Passwords macOS app, click All in the left column (on the iPhone/iPad, go to the Passwords screen and tap All). Then do a search for the name of your Mac. If you can’t remember the name you gave it, you can search for “FileVault” or “Recovery” and look for your Mac in the results that appear.

Paste protections in Terminal

One way an attacker may try to access your Mac is through scripts and commands that are processed through the Terminal. The Terminal is the Mac’s command line interface, and you might now know it’s actually an app in the Applications’ Utilities folder. Terminal commands seem like a foreign language to most users, which is why attackers are able to use them to lure unsuspecting users to make their system vulnerable. They find some sort of social engineering opportunity or send an email posing as an authority, and then they give the user a command to copy and paste into a Terminal window.

As a safety measure, the Terminal will now post a warning when you attempt to paste something into the command line interface. You do have the option to bypass the warning and perform the paste if you want. This new protection was implemented in macOS Tahoe 26.4.

Fortunately, for those who use the Terminal often, macOS can determine if you need to see the warning or not. For example, software developers who have Xcode and other tools may not see the warning because they use the Terminal frequently, and posting the warning isn’t necessary.

Background security fixes

With macOS 26.1, Apple implemented Background Security Fixes, which is the ability of macOS to install “lightweight security releases.” There are times when Apple wants to issue a security fix but doesn’t want to wait and include it in the next point-release update. Instead, they’ll release a Background Security Fix.

If your Mac’s OS is up to date, then the first Background Security Fix was installed and you may not have noticed it. Back in March, Apple released a fix for a WebKit vulnerability. Apple maintains a list of released fixes you can check.
