I bought a new Macbook recently which run Catalina (OS X 10.15) which is basically no different to OS X 10.11 or 10.10 – the only difference is that it slows your computer down if you are on an older model. Since Steve Jobs died innovation at Apple basically stopped; all the new devices is just the same as before but maybe with an extra camera or a bit more RAM or a faster CPU. The laptop that I bought is no exception compared to the Macbook Air that I bought 8 years ago.
I use Adobe Photoshop CS6 which requires Java 6 SE; it’s supposed to be an older version of JAVA but it actually does the job; but the JAVA downgrade that Apple offers doesn’t work for Catalina (10.15) – https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US; it should but they just deliberately made it so it doesn’t.
Open the Java package with Pacifist and install it. Don't mind the checksum errors. It should just work. It will be installed on /JavaVirtualMachines/1.6.0.jdk If you need to switch from other versions of Java, use /usr/libexec/javahome -v 1.6. Using Java SE on macOS Catalina With macOS 10.15, Apple introduced new application security checks, which are used by Gatekeeper to verify the contents of distributed software. When you install or run software for the first time, Gatekeeper verifies that the software has been notarized. Mac OS X Yosemite (and the newer versions) are having a later version of Java Runtime (SE 8.0). However, Java Runtime is not backward compatible. So, even when the operating system have installed Java Runtime 8, it will NOT run apps that rely on Java Runtime 6. Apple's Java 6 is no longer supported on Catalina, so the Java for macOS 2017-001 installer is toast too. Replace the old 32-bit Java 6 dependent applications with Catalina compatible applications, or use them on older releases of macOS than Catalina. To open 'this Java application' you need to install the legacy Java SE 6 runtime. I follow instructions in 'More info' and on the Internet to download Java from Apple, but Java cannot be installed because 'A newer version of this package is already installed', shown below: My MacOS is Catalina v.10.15.3. How can I escape this loop?
I found a great post online on how to fix this:-

The error message that you will receive is “A Newer Version of this package is already installed” but it’s not.
I followed the instructions on the Harris Geo Spatial website and managed to generate a package that I was able to use to install JAVA6 SE; to save people hassle I have uploaded here and you can download it directly to save yourself from following the steps yourself. You download:-ModifiedJava6Install.pkg
I also download JAVA 7 too which can be downloaded here – it needs X86_64 architecture:-
jdk-7u80-macosx-x64.dmg
