Let's start with the steps to take if you're still running Mojave. The steps are different depending on whether you're still running macOS Mojave or have already upgraded to Catalina. Parallels is easiest to use, but VMware Fusion isn't far behind. These prorgrams are designed mostly for running Windows on a Mac, but you can also use them to create a virtual machine that runs macOS in a window on your Mac desktop. The easiest method is this (but keep in mind that it costs money): Buy a copy of Parallels Desktop or VMware Fusion if you don't already own one. Both methods work, but both seem to me inconvenient and time consuming. If you need to run a 32-bit app, Apple unofficially recommends either that you keep an old Mac on hand that runs a pre-Catalina version of the OS or that you partition your current Mac so that it can start up with an older macOS version as well as Catalina. ( Wine stands for 'Wine Is Not an Emulator,' but, effectively, it emulates Windows features so that Macs and Linux boxes can run some, but not all, Windows applications.) The 32-bit apps you find on your machine are typically of two kinds: older Mac apps that have been abandoned by their developers (or that developers are slow to update) and apps based on the Wine software project that lets Macs and Linux computers run Windows software.

Study this list, and if you find 32-bit apps that you need, you'll have to find a 64-bit update or replacement-or you can implement the workarounds below. You may be surprised by how many 32-bit apps you have. All your 64-bit apps will show a Yes in this column. Find the column headed '64-bit (Intel)' and click on the column heading. Your Mac will take a while to gather information about your apps and then displays a list of all the apps on your machine. The easiest way to do this is to click the Apple icon in the upper left, then About this Mac, then System Report, and scroll down to Software/Applications.

Here, we show you how to run 32-bit apps on an OS that isn't designed for them.īefore you update to Catalina, find out whether you're using any 32-bit apps that you can't do without. Still, for many users, Catalina blocks apps that they've relied on for years. Apple warned us years ago that this change was coming, and there's no doubt that an all-64-bit OS like Catalina is more efficient than an OS that runs both 32-bit and 64-bit code. The biggest change is that Apple ripped out all the code that, in earlier versions, made it possible to run older 32-bit apps in Apple's 64-bit operating system.

Apple's latest version of macOS, 10.15 Catalina, looks a lot like earlier versions of the operating system, but is vastly different under the hood.
