All you have to do is run Mojave in a virtual machine to keep your older software functioning. Happily, you can still upgrade to Catalina without losing access to older apps, thanks to virtualization. However, many apps weren’t worth the time or money for developers to refresh with 64-bit support. That time has now arrived.Īpple began putting 64-bit processors in Macs starting around 2006 and shifted to greater OS support for 64-bit apps a decade ago with 10.6 Snow Leopard. In June 2018, Apple confirmed the end of 32-bit apps, noting that 10.14 Mojave would be the last operating system to allow them to run (see “ macOS 10.14 Mojave Will Be the Last to Support 32-Bit Apps,” 12 June 2018). The new version of macOS marks the end of old 32-bit apps whose software code was never refreshed to support 64-bit CPUs. We’re nearing 32-bit-ageddon with the release of macOS 10.15 Catalina sometime in October 2019.
