“Legacy Software” in macOS Catalina

If you’ve been using a Mac for a while, and upgraded to macOS Catalina, you’ve probably seen some mention of 32-bit software. Catalina is a 64-bit operating system, and cannot run 32-bit apps. If you want to know more, here is an article I wrote about this.

In the article I link to above, I explained how to find 32-bit apps on macOS Mojave, using the System Information app. Since there is no 32-bit app support in Catalina, System Information no longer shows the bitness of apps. However, it does have a “legacy software” section.

Legacy software

But I have deleted or upgraded all the software listed here. I’m guessing that this list was made when I upgraded to Catalina, and hasn’t been updated. But what’s the point of having such a list? Even if I hadn’t acted on all this software, the list doesn’t make it that easy to find where it is located. One item has a path of:

/Volumes/Steinberg Download Assistant/Steinberg Download Assistant Setup.app/Contents/MacOS/Steinberg Download Assistant

This suggests that the software is, perhaps, in a disk image that was mounted on my Mac at some point, which is likely, as I did install some Steinberg software a while back. But how can that path be listed? When was this snapshot of software made?

This list is quite unhelpful.
