Until macOS 10.15 Catalina, Mac users knew: their startup volume was a single volume, just as it appeared! (Okay, for Fusion drive users, there are two physical drives managed by software to appear as a single “disk drive,” but that’s separate from the data organization that is a volume on a drive.)
- OnyX 1.3.1 for Mac OS X Jaguar 10.2 Requirements: PowerPC-based Mac using Mac OS X Jaguar 10.2 with BSD subsystem. OnyX only runs from an administrator account.
- Snes9x is an emulator with a long history. First released in 1998, (according to Wikipedia) a Mac port was created by John Stiles and released the same year. This port was PowerPC native, and used the Macintosh Toolbox API. In 2000, it was updated to use the Carbon API, allowing it to run on classic MacOS, as well as OS X.
- The Mac in question is a server for two computer labs, hosting 60 Macs with a few terabytes of data spread out across 200 user accounts. Hosting the Users folder on the internal drive is simply not a good option for us. Symbolic links are no longer supported (for the root directory folders) in Catalina / 10.15, so this no longer works.
- By far the easiest way to send a fax from a Mac nowadays is by using an online fax service. In fact if you’re using macOS Mojave and Catalina, it’s the only way to send and receive fax documents from a Mac in 2020.
As I wrote a couple of months ago, Apple relies on a feature in APFS (Apple File System) called “volume group.” This allows macOS to link together two separate volumes to appear as a single drive. Apple chose this method as a way to enhance security, putting read-only system files on one volume and your changeable data, home directory, preference files, and all the rest on another.
But where does this leave you if you want to clone your startup volume and create a backup that can be used as a one-stop shop for restoring a failed drive or Mac, or which can be booted from? Fortunately, all the software you need is up to date.

Time Machine correctly archives your entire startup volume (as well as other volumes you might specify), letting you restore a Catalina drive as you would a previous version of macOS.
Carbon Copy Cloner ($40) has supported making full clones that boot with Catalina since August 2019. If you haven’t used CCC in a couple of years, you need version 5 for Catalina support.
SuperDuper! ($28) released version 3.3 in November with full Catalina backup and boot support. Its maker, Shirt Pocket Software, has never charged for updates, so if you own any previous release you can download and use the latest version.
