macOS Catalina 10.15.7

macOS Catalina 10.15.7 comes with important security updates and fixes for known bugs on your Mac. Here is what you will get with the latest version:

Catalina Mac OS 10.15. is the successor to macOS Mojave. The new features that this update brought to Mac include a battery health feature that is supposed to reduce the rate at which the device’s battery ages. This feature can analyze the charging patterns of the battery and the current state of its health and then control the extent to which it would get charged so as to slow-down chemical aging. This feature can be turned on and off from System Preferences > Energy Saver

Newest Features

Catalina’s OS name is inspired by Santa Catalina Island, an island located in California’s Channel. 

Notable changes made with macOS Catalina are the removal of iTunes, the addition of the Sidecar feature, the expansion of the iPhone and iPad Screen Time featureto Mac computers, and others. Additionally, significant changes have also been made to the macOS security. Below, we will have a quick look at each of these improvements:

Battery Life Improvement

The CPU and TurboBoost function have been both optimized for increased battery life. It works by shutting off CPU cores but allowing for a higher frequency rate on working cores to sustain performance.

iTunes removal

iTunes has been a part of Mac computers ever since 2001 but with Catalina, it has officially been terminated. Now, instead of iTunes, users will have access to three separate apps that together take over the functions of iTunes. Those apps are MusicTV, and Podcasts.

As for managing your devices, with Catalina, this is done via Finder and not via an app.


This feature allows Mac users who also own an iPad to turn their iPads into second screens for their Mac computers. The Mac screen could be extended to the iPad or they could both show the same content (mirror screen). Sidecar also works with Apple pen, enabling users to use their iPads as drawing tablets.

Screen Time

This is an iPhone and iPad feature that, with Catalina, has been carried over to Mac computers. Screen Time allows you to track the usage of all your Apple devices, providing useful information on how your time is being spent across them.

Find My

The Find My app implements the Find My Mac and Find my Friends technology to provide users with the ability to potentially find their lost/stolen device. This technology does this by employing Bluetooth and the help of other devices that are near the lost/stolen one.

Security Improvements

One of the biggest changes made that came with Catalina is related to the security of the macOS.

The first improvement is the Read-Only system volume – a dedicated system volume that allows Catalina to run separately from other data, thereby preventing any potential attempts at tampering with system files done by malware and hackers.

Next, the Gatekeeper feature, which previously only used to check the sources of new apps, now also checks the apps themselves and prevents them from running if it deems them potentially unsafe.

Thirdly, unlike earlier macOS releases, Catalina requires explicit user approval if an app wants to access data stored in the Desktop, Downloads, and Documents folder. Only after the user gives their permission would the app be able to gain access to such data.

Other changes

One other notable change is that 32-bit apps can no longer be run on Mac computers if the latter have been updated to Catalina, making macOS Mojave the last macOS release that supports 32-bit apps.
