I wrote about this process a few years ago – read it here – when many editors wanted to retain access to OX X 10.6.x to run Final Cut Pro 7 and DVD Studio Pro. You are running beta software and want to isolate it from your normal operations.You want to run other operating systems, such as Windows or Linux.You want to retain an older version of the macOS to support older programs, while still upgrading to newer versions to run current and future programs.There are three main reasons for creating multiple partitions of your internal drive: We do this by “partitioning,” or dividing, the internal boot disk into two or more sections, each with its own version of the macOS. Instead, create a new Volume and install the OS you need into it.Ī “dual boot” system disk allows you to run two different operating systems on the same computer.
UPDATE: As you’ll see in Larry Hinkle’s note at the bottom, APFS volumes do not support partitioning.
