What is Techtool Protection?

This is one of the most common questions that we get about Techtool Pro. When Techtool Pro first launches or updates, it asks if you would like to install the Techtool Protection system preference pane. This (optional) system preference extends the functionality of Techtool Pro and provides some continuous monitoring features.

Catalina's Secret Disk

In macOS Catalina, your startup disk has a secret. When looking at a hard drive in the Finder, a single icon to represent that volume. In Catalina, your startup disk is now comprised of two volumes, but will still show up as one when viewed from the Finder. Under the hood, the system now resides on a read-only volume, while your data is stored on a separate volume. Catalina uses some tricks to present the two as one whole volume.

Catalina Disks

When using Techtool Pro 12 with Catalina, the Volume Structures test or Volume Rebuild tool will list both the system and data partitions. The read-only system volume will be the name of your startup disk, while the data volume will be the name of the startup disk with the word Data added to the end of the volume name.

When you need help getting home

Techtool Pro provides a number of ways to create a secondary startup disk for troubleshooting purposes. The eDrive and Protogo tools provide ways to either add a startup partition to an existing disk or create a dedicated drive, respectively. Whether you've created an eDrive or Protogo device, when you're done using it, you (most likely) will want to return to your primary startup disk.

The Startup Disk system preference pane is perhaps the most familiar way for assigning a startup disk for your Mac. It's certainly the most straightforward. Open the Startup Disk system preference pane, select a startup disk and you're done. It may not be the best method, however, when you want to start up from a different startup disk only once. The reason for this is that when you select a startup disk in System Preferences, you're telling your Mac that you always want to use that disk to be your startup disk.
