Surprise: Software from a verified developer could do the same, because Apple does not verify every program written for the Mac. You just give a “verified developer” more confidence. The developer of the software could of course register with Apple, but would then have to pay money for it and would also be considered a verified developer. Mac App Store and identified developers: When you try to open a new app and it’s not on the list of identified developers that’s saved within the operating system, the Mac tells you it can’t open. If you have downloaded it but cannot get it to open because your computer doesn't allow software from unauthorized developers, go to Downloads in Finder. Right-click your software and press open. Put in your admin password. I just upgraded the operating system for my Mac Book Air to Catalina, 10.15. As well, I upgraded my OpenOffice to 4.1.7. However, when I try to open OpenOffice, I get a message that it cannot be opened because the developer cannot be verified.

Diagnosis: Modern macOS, like Mojave and Big Sur, includes a technology called Gatekeeper, which is built to help you safely open apps on your Mac. For sure Apple App Store is the best place to get software applications, but in many cases, you'll need to download and install apps out of the store. To distribute apps without App Store, it requires the developer to have valid Apple Developer ID and get their apps notarized. Otherwise, it has large chance that they'll get the following error: 'XXX can't be opened because Apple cannot check it for malicious software.'

In Windows, you can use the Win key + arrows to snap windows to half the screen. Is there a OSX equivalent? I found a program that does this called HyperDock. It worked well, but it was just a trial version. It has more features than I care about and costs to much (IMO). Are there any other programs that are free or cheaper that do the same thing? https://visualever938.weebly.com/window-snap-mac-app.html.

Mac App Not Opened Because Developer Cannot Be Confirmed Released
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:
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 a malicious 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.
How to open an app that hasn’t been notarized or is from an unidentified developer
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. 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.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
