Matrix Screensaver Mac Catalina

Aerial is a free and open-source Mac screen saver based on the new Apple TV screensaver. It features stunning Aerial videos shot over various cities and locations including New York, Hawaii and China; as well as earth videos from the ISS, and the new underwater videos introduced in tvOS 13.
Of course, screensavers do still serve a purpose (beyond the original intention to reduce screen burn-in, which was a much bigger problem for classic CRT monitors); for example, you can use a hot corner to activate a password-protected screensaver to lock down your Mac in an instant.
Matrixgl is a screen saver for Mac OS X v10.5 or later. This is a port of the Windows/Linux OpenGL screen saver made by Alex & Eugene Zolotov and modified by Vincent Launchbury. What's new in matrixgl Version 2.2.
Is my screensaver overloading the Mac OSX Catalina Screensaver Engine? I developed what I felt was a neat little program in processing. It sets up some rngs and then graphs the counts of each output of each rng.

Activation Lock helps you keep your Mac secure if it's ever lost, stolen, or misplaced, and can improve your chances of recovering it. Activation Lock can continue to deter anyone from reactivating your device without your permission, even if you erase your device remotely. All you need to do is keep Find My Mac turned on, and remember your Apple ID and password.

What you need

Upgrade your Mac to macOS Catalina.
Your Mac must have the Apple T2 Security Chip. You can learn whether your Mac has this chip in Apple menu  > About this Mac > System Report > Controller.
Enable two-factor authentication for your Apple ID.
Leave Secure Boot enabled on its default setting, Full Security, with 'Disallow booting from external media' selected under the External Boot section.

How it works

When you turn on Find My Mac, your Apple ID password or device passcode is required before anyone can turn off Find My, erase your Mac, or reactivate and use your Mac.

Just transfer yourself into the Matrix world. The matrix stripes, warping desktop, flying objects, matrix tunnel and other visual effects are included. 3D Screensavers, 3D Live Wallpapers and HD Background Images for PC and Mac computers, tablets and smartphones.

Activation Lock is automatically enabled when you set up Find My on devices that meet its system requirements.

If your Mac goes missing

If you ever misplace your device or think it may have been stolen, you can sign into iCloud.com or use the Find My app to locate your device on a map, play a sound, lock your Mac, or erase it. Activation Lock works in the background to make it more difficult for someone to use or sell your missing device, but you can still remotely lock your device with Find My to secure it with a unique passcode and display a message onscreen for anyone who may find it.

How to check that Activation Lock is on

Choose Apple menu  > About this Mac.
Click System Report.
Click Activation Lock Status under Hardware.
