My Macbook Pro has nixed from the upgrade to Mojave (I believe) so I can no longer upgrade the OS to any of the newer versions. I knew the time was coming, but it still works and I'm not ready to shell out the money for a new Mac (I have an iPad and iPhone). So I wasn't paying attention and deleted some apps I actually need. Wouldn't you know the Apps have been upgraded to the new Catalina OS. Obviously, I can still use the older app, but not sure where I can get them? Some are in the apple store and some are with the 3rd party manufacture. Does anyone know where older apps might be stored? CNET????
