Will Legacy Adobe Lightroom Work On Upgrade Of Mojave –> Monterey?

I have Mojave OS if I upgrade to newer OS will all my current apps be able to work? I have a legacy version of Adobe Lightroom, that I don’t want to lose.
BY THE WAY, many thanks for the workaround. for Instagram. Very excited to continue viewing and using your Forum. Richard N.

    Impossible for me to say without knowing the details. Which apps and which versions. "Legacy" can mean a lot of things.

    Basically, starting with Catalina you can only run apps compiled for 64-bit processors. Before that macOS still supported running older 32-bit apps. Developers were told of this change a long time ago, and unless the developer had abandoned the app or procrastinated a great deal, they had 64-bit apps out long before Catalina. (Earlier versions of macOS supported both 32-bit and 64-bit).

    If your "legacy" version of Lightroom is so old that it is 32-bit, then no, it won't run in Catalina or beyond. You can select the app in the Applications folder and use File, Get Info to see if it is 32-bit or 64-bit.

    This change started 6+ years ago and Catalina came out more than 2 years ago. It is time to move on from old apps that are still 32-bit. You can simply get the new version of Lightroom. Your only other option is to stay behind in 2020 with Mojave forever. And that won't work because one day you may get a new Mac and that will only run the current version of macOS and only support 64-bit apps. So update now while you can do it at your leisure instead of possibly needing to do it later on when you are forced to.
