Apple released macOS 10.15 (Catalina) on 7th Oct 2019 and now it is publicly available for download. With multiple features presented at the WWDC 2019, here’s an overview of the new security and privacy features introduced in Catalina.
Enhanced Gatekeeper
Gatekeeper, is an important outer layer of security, designed to prevent malicious software from running on your system. It ensures that all new apps you install — from the App Store or the internet — have been checked for known security issues by Apple before you run them the first time.
Apple announced that it is enforcing app notarization prerequisites on Feb. 3, 2020; Apps that aren't notarized by then will not work on macOS Catalina anymore. Is there a possibility to install software that was not 'notarized' for macOS Catalina? I have an application that worked on macOS Mojave but cannot be installed anymore on macOS Catalina. I think the developers must 'notarize' this software. Checking with spctl -a -vv my.app confirmed that it is rejected.
From macOS 10.15 Catalina, Gatekeeper will now perform known security checks periodically to check that code has not been tampered with. Also all software, whether quarantined or not, and regardless of how that code is loaded, will be scanned for malicious content.
In a future version of macOS, unsigned code will not run by default.
Notarization
In order to run on macOS Catalina, Mac apps, installer packages, and kernel extensions that are signed with Developer ID must also be notarized by Apple. It will help users gain more confidence that the software they download and run, no matter where they get it from (App Store or the internet), is not malware by showing a more streamlined Gatekeeper interface.
For macOS 10.14.5, Kernel extensions signed after April 7th 2019 must be notarized in order to load
For macOS 10.15: All software must be notarized from June 1st 2019
User Privacy Protection
User privacy protection (aka Data Protection) is designed to ensure that even if malicious software is able to get around Gatekeeper, it doesn’t necessarily have access to your most sensitive data and resources.
macOS Catalina will now protect most of the common locations where you store your files, such as Documents, Desktop, and Download folders, Trash, iCloud Drive/other cloud storage providers, as well as external, removable, and network drives. Apps must also request your permission to perform key logging, or to capture still or video images from your system. Similar to Mojave, the list of approved apps can be viewed and managed in the System Preferences Privacy pane.
User consent is not required for an app to create new documents in any of these protected locations, just to read existing contents, the contents of files that are already there. For example, a file transfer app can continue to save new files to the users downloads folder without triggering a consent prompt.
Dedicated System Volume
macOS Catalina will run in its own private, read-only volume, so there will be no way for malicious apps to write files to the volume or alter existing files. The installation of macOS Catalina creates two volumes, one with the operating system, and another with data, segregating the two types of files.
User-space System Extensions
macOS Catalina will be the last version that will run existing kext’s (kernel extensions). Kext’s are slowly being replaced with system extensions (user-space apps), which will exist outside of the protected system volume. This will ensure that if something is wrong with an extension, either from poor design or an attack from malware, the system itself is not affected.
Furthermore, installing kext’s or system extensions will likely require a restart of the Mac.
Removed Support for 32-bit AppsMacos Catalina Run App Not Notarized To Be
Catalina has removed all support for 32-bit code. Thus, a number of older apps that have not been updated to 64-bit will cease to run.
Activation Lock on Macs
Similar to iPhone, if you have a Mac which contains T2 security chip, you will now be able to prevent the unauthorized use of your Mac, if it is lost or stolen. This T2 chip can be found in Mac mini, MacBook Air, and MacBook Pro from 2018 or later, and the iMac Pro.
Find My
Find My Mac will allow you to locate a lost device even if it’s asleep and not connected to the network, via crowd‑sourced location and Bluetooth beacon. When you report your device as missing and another Apple user’s device is nearby, it can detect your device’s Bluetooth signal and report its location to you. User Privacy is not compromised as device information sent is completely anonymous and encrypted.
Wrap Up
Apple is incorporating multiple security features and enhancing the existing ones considering the emerging threat landscape. Most of these security features provide decisions in user’s hands, but what will help user to take right decision? How can you protect your Mac from the security threats out there? Here are a few defensive measures to minimize the level of risk: Soundfreaq app for mac.
I hope this list will help you anticipate the changes required when you decide it’s time to upgrade to macOS Catalina. What changes in macOS Catalina are you most concerned about, or looking forward to? Let us know in the comments, below.
The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. View the app security settings on your Mac
By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”
Open a developer-signed or notarized app
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it: Qr code mac app.
If you see a warning message and can’t install an app
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.

If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.

If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.

The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
