Download the latest version of Adobe AIR for Mac. Run applications created by this Adobe technology. Adobe, just like Sun Microsystems' virtual environment. If the Installer displays an Authenticate window, enter your Mac OS user name and password. Install the runtime on a Linux computer. Note: At this time, AIR 2.7 and later are not supported on Linux. AIR applications deployed to Linux should continue to use the AIR 2.6 SDK. Adobe AIR is installed to the following location: /opt/Adobe AIR.

In case you're new to AIR, which means Adobe Integrated Runtime, it's a platform that runs applications across multiple systems without coding in more than one language. It's powerful and respected. Adobe AIR is a cross-platform runtime environment developed by Adobe. AIR stands for Adobe Integrated Runtime and it allows for the creation of great Internet apps that can be executed on a variety of platforms, including Windows, Linux, and Mac OS X.
Adobe Air lets developers build desktop apps by implementing the same the programming skills they've used to do work on the Internet. That way, you'll be able to run your desktop apps with Flash, Flex, HTML, AJAX, CSS, and PDF, and enjoy all the great things they have to offer without having to run a web application.
Many apps made to run in this environment have already started sprouting up, all with great results. Everything seems to point to the fact that Abode Air will be a must-have software for any Mac user in the future.
Notes
For Mac OS X 10.4.9 or higher.Adobe Air Mac
In my day-to-day, I don't have any use for Adobe Air products. For work on the other hand, we have a timesheet system built by Deltech called Traffic Live. My personal views on the software or process not withstanding, there's a few steps you need to take if you're running macOS Catalina. The main issue you may encounter is that macOS thinks the Air runtime is damaged. It's part of Catalina's quarantine system.
Step 1
Download Adobe Air's installer and install
Step 2
Go to Terminal (apple/command + space and then search for Terminal) and run the below commands. Note, you may have to enter your password on the second step
cd /Library/Frameworks
sudo xattr -r -d com.apple.quarantine ./Adobe AIR.framework
Adobe Air Driver
The first step navigates terminal to the right folder, and the second ensures the app can install despite the Apple quarantine.
Step 3
Ensure the Adobe Air application you want to run is on your local computer (e.g. in your downloads / applications folder)
Adobe Air Mac Damaged
That should be it..!
