Getting the most out of your Protogo devices

CatalinaProtogo

Techtool Pro's Protogo tool is useful for creating a dedicated diagnostic device that you can use to start up your Mac (and other Macs compatible with your OS) for troubleshooting and repair. To get the most out of your Protogo device, it is important that you choose the right drive.

The faster the drive you use for your Protogo device, the better your experience will be. For the absolute best results, use an external SSD connected via Thunderbolt or USB 3.1. If you are using a thumb drive, they vary very widely in terms of performance. In our experience, the very best performers (which can still be found for less than $20) are those which utilize a small SSD inside the thumb drive. One such example a this model by SanDisk, linked below. At the minimum, it is best to use USB 3 or 3.1 USB sticks, even on USB 2 equipped Macs, because the memory they use is still faster when connected via USB 2. (And many USB 2 devices use memory that is much slower than the connection itself.)

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.
