Jul 06, 2006 The latest update to the Mac OS sparks a privacy debate, as a feature meant to authenticate desktop widgets is believed by some to be phoning home to Apple.

Apple has released macOS 11.3, fixing a serious flaw that allowed an attacker to sneak malicious files past the operating system's Gatekeeper security mechanism.

Gatekeeper is one of the primary macOS defenses against the installation of malware, explained Cedric Owens, the security researcher who found the bug, in a message to The Register.

The vulnerability, he said, lets an attacker rig a malicious file so it won't get blocked by Gatekeeper when a user tries to open it. He considers it to be one of the most dangerous he's encountered on recent versions of macOS.

'A victim detonating one of these payloads would give the attacker the ability to remotely access sensitive data in directories not protected by TCC [Apple's Transparency, Consent, and Control framework],' said Owens, who elaborated on his findings in a Medium post.

In an email to The Register, security researcher Patrick Wardle, founder of free security project Objective See and director of research at security biz Synack, said, 'This bug, a subtle logic flaw deep within macOS’s policy subsystem, trivially bypasses many core Apple security mechanisms, such File Quarantine, Gatekeeper, and Notarization requirements, leaving Mac users at grave risk.'

He has written up the issue in full here.

Most Mac malware infections, he said, are the result of users unwittingly running infected software. He pointed at the recently identified Silver Sparrow malware, which managed to infect over 30,000 Macs in a matter of weeks, despite the need for user interaction.

Apple has implemented interrelated mechanisms over the years to reduce the threat of interaction-based malware, such as File Quarantine in 2007 (Mac OS X Leopard), Gatekeeper in 2012 (Mac OS X Lion v10.7.5), and Applications Notarization in 2020 (macOS 10.15).

Thanks to this bug, Wardle explained, 'it is possible to craft a malicious application that though unsigned (and hence unnotarized) is misclassified and thus is allowed to launch with no prompts or alerts. This effectively reverts aspects of macOS security back to pre-2007 levels.'

The logic flaw Wardle mentioned has to do with a code oversight that misclassifies a script-based application (run via the shell, /bin/sh) without an Info.plist configuration file as 'not a bundle,' which means the script can execute without any Gatekeeper alerts or permission prompts. It's been around since the release of macOS Catalina 10.15 in 2019.

Objective See's free BlockBlock security tool has a mode to detect apps that aren't Notarized, like a malicious script attempting to exploit the Gatekeeper bypass. So too apparently does Jamf Protect, an enterprise product.

Wardle said he and former colleagues at security firm Jamf found Mac malware that exploits this bug in the wild earlier this month.

According to Jaron Bradley, macOS detections expert at Jamf, the malware detected using this technique is an updated version of Shlayer, a family of malware discovered in 2018 that's one of the most commonly seen forms of Mac malware.

'One of our detections alerted us to this new variant, and upon closer inspection we discovered its use of this bypass to allow it to be installed without an end user prompt,' Bradley explained in a message to The Register. 'Further analysis leads us to believe that the developers of the malware discovered the zero day and adjusted their malware to use it, in early 2021.'

Shlayer's goal is to install adware on the victim's computer, so the malware authors can profit from ad revenue, said Bradley, noting that the earliest sample using the Gatekeeper bypass technique was spotted on January 9, 2021.

Owens said he reported the bug to Apple on March 25. Apple fixed the issue five days later in a macOS Big Sur 11.3 beta release, said Wardle, based on scouring for changed strings in the beta code. The official release of macOS Big Sur 11.3 should help close this particular hole once macOS users apply the update. ®

If you’re typing in languages other than English, chances are you have to deal with accents. German, Italian, Spanish, and other languages use a bunch of letters with diacritical marks — yeah, those weird curls on top of regular letters. So how to type French accents on Mac? What to do if you need to type a message to your Portuguese friend quickly?

Today, I’ll share some tips and tricks on how to do accents on Mac. Each method is useful in different ways: from being the best for working at speed to typing characters without touching the keyboard at all. We’ll also see how to optimize your system performance by getting rid of unnecessary language files.

How to add accents on Mac in 3 different ways

There are three quick methods of how you can enter letters with accent marks. Let's see each one in detail.

Method 1. Use the accent menu

If you’re using the latest macOS versions, you can easily type accented letters with a long press on a specific key. To display the accent menu:

1. Press and hold a letter on the keyboard until its alternative characters appear. The menu doesn’t pop up if no extra characters are available for the key you’re holding.
2. Click on the character to pick it from the list — for example, é.

You can also hit the number key associated with the accented character you want to type. Another way is to use the left/right arrow keys. Once you select the needed character, tap the Space bar.

If you want to close the menu without typing any letter, press Esc (escape).

Although the accent menu is available in major apps, web browsers, and text editors, there are still some environments that don’t support it.

If you want to learn how to type Italian accents on Mac, this method is the way to go. It sticks to the most-used characters but doesn’t work so well for more exotic ones. The best part is that you don’t have to keep tons of key combos in your mind.

Method 2. Use dead keys

If you find yourself regularly using accented characters, then learning some useful key combos can save you tons of time. Here’s how shortcuts work:

1. Hold Option as a modifier key and press a key that corresponds to a specific diacritical mark.
2. When the accent preview appears, release the keys and type the letter you want to apply the accent to.

Wondering how to type Spanish accents on Mac? To get ñ, for example, you need to hold down Option-N, release this combination and then press N again. To get the capital letter Ñ, add Shift: Option–N, Shift–N. As simple as that – now you can order piñatas online!

The dead keys may seem tricky at first, but if you use them for a while, they’ll feel more natural. To see where all possible accents are located on your keyboard layout, check out the Keyboard Viewer:

1. Go to the Input menu on the right side of the menu bar.
2. Choose Show Keyboard Viewer to open a new window with the keyboard layout. It’ll show the keyboard depending on the current input source you use.
3. Hold the Option key to highlight the dead keys — they’re outlined in orange. Here’s an example of the standard QWERTY (English) keyboard.

If you can’t find the ‘Show Keyboard Viewer’ command in the Input menu, select System Preferences from the Apple menu, and click the Keyboard icon. Then, go to the Keyboard tab and check ‘Show keyboard and emoji viewers in the menu bar’.

• Acute (á, é, í, ó, ú, ý): Option–E, the letter
• Circumflex (â, ê, î, ô, û): Option–I, the letter
• Tilde (ã, õ, ñ): Option–N, the letter
• Umlaut and dieresis (ä, ë, ï, ö, ü, ÿ): Option–U, the letter
• Grave (à, è, ì, ò, ù): Option–`(grave), the letter
• Cedilla (ç): Option–C
• OE Ligature (œ): Option–Q
• Æ Ligature (æ): Option–’ (apostrophe)
• å: Option–A
• ø: Option–O
• ß: Option–S
• ¿: Shift–Option–?
• ¡: Option–1

Method 3. Character Viewer

Looking for a way how to type Czech accents on Mac? Character Viewer comes especially in handy. While this method is widely used to add emoji into messages, it’s far more than just entering funny faces and symbols. Here’s how to use it:

1. Put the insertion point in the text where you want the character to appear.
2. Press Command-Control-Space to launch the Character Viewer. Or choose Show Emoji & Symbols in the Input menu if you’ve already set the option to show this command there.
3. Click the expand button in the upper-right corner to display more categories.
4. Select Latin on the left sidebar to open a list of accented characters.
5. Double-click the one you want to insert into the document. That’s all!

Bonus tip: How to get rid of extra language files

Most of the apps on your Mac are developed to run on the different markets around the words. That means each of these applications comes with dozens of language files, also known as localizations used to display the app on the user’s native language.

Since you don’t speak most of these languages, such files just clutter your Mac. Luckily, you can safely remove them. Instead of trashing useless localizations manually for every single app, use the software I've been using for a while — CleanMyMac X.

Even though there are no magic buttons in life, its Smart Scan feature does a lot. It cleans up your Mac from unneeded files, detects potential threats, and shows how you can speed up your system. With a few clicks, CleanMyMac X will cut the extra weight and keep your Mac’s performance on top. Here’s how to use it:

1. Download CleanMyMac X for free.
2. Launch the app and hit Scan.
3. When the scan is over, click Run.

If you want to edit the list of localizations before removal manually, click Review Details to proceed to the System Junk module. Once done, go back to the summary and press Run.
