Apple continues to add new features to Safari on a regular basis to try to make our web browsing experience faster, easier, and—above all—more secure.
Apple helps you keep your Mac secure with software updates. The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. MacOS checks for new updates every day, so it’s easy to always have the latest and safest version. May 01, 2020 How to Change Application Permissions on a Mac. This wikiHow will show you how to change what different apps can access on a Mac. Click on the Apple icon. It's the Apple logo at the top left corner of the menu bar. Mac OS X automatically sets permissions to limit a user’s access to system files and other user directories. If that protection isn’t good enough, you can change permissions to prevent other users from doing stuff like editing your 'Great American Novel,' reading private financial documents, or opening a specific application.
You can open up a private browser window anytime you want in Safari's file menu and Safari won't save your browsing history and will ask websites you visit not to track you. But there are a few more steps you might want to consider taking.
The place to go for most of these things is in Safari's preferences window, accessed from the Safari menu.
How to guard against unsafe files
As with all things related to security, there's a balancing act between convenience and safety. Safari will automatically open certain types of 'safe' files you download from the web as a matter of convenience. But because a malicious file could be disguised as a 'safe' file, it's a good idea to guard against unsafe files—and it's as easy as checking a box.
- Launch Safari. If it's not in the Dock, you can find it in the Applications folder.
- From the Safari menu, choose Preferences...
- Click the General button.
- Uncheck the box to Open 'safe' files after downloading.
Downloads will occur as they usually do, and to the location you have chosen, but the files won't automatically open.
How to identify fraudulent websites
Safari already identifies websites that use encryption (indicated by a padlock icon in the address bar) and an EV certificate which indicates a more extensive identity verification of the website operator (indicated in green). Safari also uses Google Safe Browsing technology--which is simply a list of websites that may contain malware, unwanted software, or phishing scams.
If it's not already on, here's how to do so:
- From the Safari menu, choose Preferences...
- Click the Security button.
- Check the box to Warn when visiting a fraudulent website.
If you happen to run across one of these sites, Safari will put up a full-screen warning about the site before you can proceed.
How to disable JavaScript
Many—if not all—webpages contain JavaScript, which enables certain functionality for web pages, such as displaying the time and date or displaying an image from a set of options.
You can disable JavaScript if you like, but it may impact the functioning of the web page.
- From the Safari menu, choose Preferences...
- Click the Security button.
- Uncheck the box to disable JavaScript.
How to prevent cross-site tracking
If you've been using Safari and suddenly seen a plethora of lawnmower ads not long after doing some web research about lawnmowers, then congratulations: you've discovered crop-site tracking. It's a way of keeping track of your behavior on one part of the internet to show you ads while using a different part of the internet. If you prefer, you can turn it off.
- From the Safari menu, choose Preferences...
- Click the Privacy button.
- Check the box to Prevent cross-site tracking and check the box to Ask websites not to track me.
Keep in mind that while you can ask websites not to track you, it's up to the website creator to honor your request.
How to block all cookies in Safari
Cookies are small text files a website may store on your Mac to help identify you or your Mac when you visit the website in the future. Examples of content stored in a cookie are your name, site browsing history, and preferences. If you don't want Safari to use cookies, you can shut it off.

- From the Safari menu, choose Preferences...
- Click the Privacy button.
- Uncheck the box to Block all cookies.
How to remove website data
If you ever decide to remove website data from your Mac, you can do it selectively for certain websites or remove all the data.
- From the Safari menu, choose Preferences...
- Click the Privacy button.
- Click the Manage Website Data.. button.
- Select a website and click the Remove button to remove the site's cache, cookies, or local storage or click the Remove All button to delete data for all websites.

How to clear your browsing history
Rather than root around through a set of checkboxes and pop-up menus, you can clear your browsing history, cookies, and website data with a menu command.
- From the Safari menu, choose Clear History...
- From the Clear pop-up menu, choose how far back you want to go.
- Click Clear History.
In addition to the history of the website pages you've visited, you'll also give the heave-ho to recent searches, a list of items you have downloaded, the frequently visited site list, and other information.
If your Mac and other devices have Safari turned on in iCloud preferences, the clear history command will remove the browsing history from Safari on those other devices.
How to check for Apple Pay on websites
You can enable Safari on your Mac to show you websites that can accept payments via Apple Pay. You can then make the payments from your Apple Watch or iPhone, or using Touch ID if it's built into your Mac.
- From the Safari menu, choose Preferences...
- Click the Privacy button.
- Check the box to Allow websites to check if Apple Pay is set up.
How to allow or deny camera, microphone, and location access
Safari includes the ability to determine whether or not websites ask can use your Mac's camera and microphone. Here's how to set it up.
- From the Safari menu, choose Preferences...
- Click the Websites button.
- From the General section of the sidebar, click Camera.
- Click the pop-up menu for 'When visiting other websites' and choose Ask, Deny, or Allow, depending on your preference.
The settings work in exactly the same way for your Mac's microphone and your location. Simply click Microphone or Location in the sidebar. Similarly, you can change the setting for currently open websites to suit your preference.
How to block pop-up windows
Some web pages that you visit will automatically display a pop-up window that will block content—often with an ad—that you're trying to view. While this can be annoying, there are some sites that require pop-up windows to work properly. Fortunately, Safari provides fine-grained control of these pop-up windows.
- From the Safari menu, choose Preferences...
- Click the Websites button.
- From the General section of the sidebar, click Pop-up Windows.
- Click the pop-up menu for 'When visiting other websites' and choose Block and Notify, Block, or Allow, depending on your preference.
Similarly, you can change the setting for currently open websites to suit your preference.
If you choose Block and Notify, a small icon will appear on the right side of the Smart Search field. Click it to display the pop-up windows for the web page.

educationApple announces new initiative with HBCUs to boost coding and creativity
Apple has today announced expanded partnerships with Historically Black Colleges and Universities to boost coding and creativity opportunities.
We design Mac hardware and software with advanced technologies that work together to run apps more securely, protect your data, and help keep you safe on the web. And with macOS Catalina available as a free upgrade, it’s easy to get the most secure version of macOS for your Mac.*
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.
Apple helps you keep your Mac secure with software updates.
The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day, so it’s easy to always have the latest and safest version.
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 state-of-the-art 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 App Store is reviewed before it’s accepted. 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.
Stay in control of what data apps can access.
Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you’ll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.
FileVault 2 encrypts your data.
With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. And on Mac systems with an Apple T2 Security Chip, FileVault 2 keys are created and protected by the Secure Enclave for even more security.
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).
Automatic protections from harmful sites.
Safari also helps safeguard you against fraudulent websites and those that harbor malware — before you visit them. If a website seems suspicious, Safari prevents it from loading and notifies you. And when connecting to unencrypted sites, Safari will warn you. So everything you need to browse without worry is right at your fingertips.
Find your missing Mac with Find My.
The 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. 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.
Keep your Mac safe.
Even if it’s in the wrong hands.
Mac Os File Permissions
All Mac models with the Apple T2 Security Chip support Activation Lock — just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
