For a while I had been getting warning messages ‘this software isn’t optimised for your Mac and needs to be updated’. It’s Orwellian for ‘we’ve made updates to the MacOS and that wrecks some of your software because we’ve declared it obsolete and legacy’. I hadn’t yet figured out what precisely was at issue, but Peter posts about how The 64 Bit MacOS Apocalypse Has Arrived.

He helpfully says where to find your list of software being declared legacy with the update to MacOS Catalina.

You can get a list of all of what Apple now refers to as “legacy software” by clicking the Apple menu, then About This Mac, System Report, and, finally, Legacy Software in the left-hand sidebar: this will show you all the 32 bit applications currently installed on your Mac that won’t run if you update to Catalina.

Here’s my list:

Some of the things on it don’t worry me, such as Citrix, as I’m sure it will get updated, and I don’t currently have clients for which I need it. Similarly the Flickr Uploader is a useless tool, which I can uninstall without consequences to my workflow. I suspect Scrivener will get updated soon enough.

Scansnap does worry me. It’s what drives my extremely useful scanner with feeder. A 450 Euro machine, that is already a number of years old and no longer on the market. So I need to find out if they will update their drivers and software. Otherwise I’m left with a key piece of expensive hardware at home that doesn’t work on my laptop. [UPDATE Fujitsu will not release new software for my scanner S1500M, as its ‘support period has expired
So no MacOS updates for me for now, as it would junk a highly capable piece of expensive hardware that is a key tool for my work.]
