While the security benefits are welcome, Apple has been rolling out updates to older versions of MacOS so you should watch for those. Those on the older versions of MacOS (Mojave and High Sierra) get to make the likely final decision on moving to Catalina or waiting for the next named release. That said these smaller updates, especially the security additions, are going to be welcome. You have a number of new features in key apps, although there is nothing earth-shattering here that makes this a must-have release. MacOS Catalina 10.15.4 is a substantive release - especially when you compare it to the threadbare 10.15.3 release in late January. But with MacOS 10.16 on the horizon, this could be the last stop on the line before we get an ‘all change’ from our Cupertino conductor. 10.15.4 offers more than that, adding in a bit of polish to some popular apps.

The only risk is that a larger delta (e.g. Than a single-version upgrade, but I have no real basis for that I feel that an automated upgrade of three versions may be riskier Normally, an OS upgrade alters the OS, but leaves your apps and data in place.

It is my plan to make a final update to the Time Machine backup for Catalina before embarking on either upgrade path. One other item: I maintain current Time Machine backups. This looks to be a rather time-consuming effort, and so the prospect of repeating this upgrade procedure 2 or 3 times is not particularly appealing.Īnd so that's my question: Am I less likely to run afoul of entanglements by adopting a "single-version-upgrade-at-a-time" approach, or does a "multi-version-upgrade" impose an insufficiently smaller risk to warrant the additional time & effort? I assume that all of these apps will require re-installation following an OS upgrade.
