Can you install macOS Catalina on an external SSD connected to your Mac? Yes, it's definitely possible. However, since Apple initiated a relatively new partition scheme (APFS) with macOS High Sierra, the process is slightly different than with older versions of macOS. This article shows you how to set up a new SSD with macOS Catalina that you can boot from.
Why Installing macOS Catalina on External SSD?
macOS can be installed on an external storage device by default, such as HDD, SSD or USB flash drive. And this priciple also applies to macOS Catalina. For permance consideration, external SSD is much better becaus of faster reading and writing speed. The good news is that external SSD is much cheaper than before and the price gap is much smaller.
Now, the big question is why you don't want to install macOS Catalina on your main hard drive. After all, if you're upgrading to macOS Catalina, you want your Mac to boot to it all the time, don't you? Not necessarily. There are several reasons why you might not want to disturb your current installation, whether it's Catalina or an older version of macOS. Here are some possible reasons.
● You might want to try macOS Catalina without having to uninstall and roll back to Mojave or High Sierra if you change your mind. Uninstalling and rolling back to an older version of macOS is time-consuming and a tedious process that is prone to errors, so you may not want the hassles that come with it.
● Your Mac (Mostly Mac Mini or iMac) is built upon on a HDD and it runs slowly. You are looking for a way to boost the performance without untouching the internal drive.
● Since there are bound to be bugs in early versions of any new OS, you might want to avoid the hassle of having it as your default OS. This way, you can update it as new versions are released, then install it as your main OS when you're happy with the stability of the software.
● You may want to have the SSD run macOS Catalina on more than one machine. Since your SSD is essentially an external drive that is portable, you may want to switch it between one Mac and the other. Instead of installing Catalina on both, you have the flexibility of simply connecting the SSD to one of the Macs when you want to boot from it.
● It's also possible that you want to run a different set of apps and, therefore, need more memory. If you use a larger-capacity SSD, this will allow you to load a ton of heavy apps like Photoshop and so on, which might not be possible with your current hard drive because it is already full of data.
How to Pick up the Right External SSD for Catalina
Mac computers are made different from PCs. It has its own hardware port and unique standards. So not all external SSDs are suitable for Macs. To maximize the performance of SSD, it should be USB 3.0 compatible, if you have enough budget, ThunderBolt port is more welcome as it has much faster reading and writing speed. Besides, the volume should be 128 GB or larger. Below is a list of best external SSDs for Mac:
