Mac Install Non App Store Software
I upgraded to Mountain Lion. Safari is not adequately functioning for numerous websites. I downloaded both Firefox and Chrome..but I can't install them because they didn't come from the App Store!!!! .. and of course, they're not offered in the App Store.

Safely Install Non-Mac App Store Apps. By default, Gatekeeper is configured to allow apps from the Mac App Store and from registered developers. Users can make this more or less strict: Open System Preferences. A common way to distribute malware is to take an app and insert harmful code into it, and then redistribute the infected app. So an app that isn’t registered by an unidentified developer might contain harmful code. The safest approach is to look for a later version of the app from the Mac App Store or look for an alternative app. #1 DJ Software for Mac and Windows The complete DJ software for all DJs.

I have also purchased several programs over the years, such as Audiobook Builder. I have a legal license and key. But I can't install from the .dmg file because I didn't download it from the App Store. It IS offered in the App Store, but I have to pay for it again!!! This is the case with 14 other programs including Disk Warrior, SuperDuper, ChronoSync, etc. Some aren't even in the App Store and others I'm expected to repurchase.
Complete user migration seems to be the only way I can get these apps on my new Mt. Lion machine...but I am amalgamating three Macs into 1 new spec-ed out laptop. I don't have the space to migrate all of the user accounts from my Air, Mini and iMac.
How do I install (legally) purchased software such as AudioBook Builder OR free software such as Firefox onto my computer without repurchasing them? Or, in the case of Firefox, when it's not available in the App Store?

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 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
Mac App Store For Windows
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.
The warning prompt reappears, and you can click Open.*
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.
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
