Re: High Sierra vs Mojave vs Catalina In reply to laurentbenoit. Jan 8, 2020 The correct answer depends on your productivity software, peripherals and the OEM software for those peripherals. MacOS 10.15 Catalina no longer supports 32-bit software. That means if you have a DAW, plug-in, virtual instrument or other apps that are only 32-bit, they will not work anymore. The bottom line is this: double-check every hardware device and piece of software before upgrading, especially when using older products (e.g. 32-bit plug-ins).
