# CalDigit TS4 Thunderbolt Dock

## Overview

This is one of my most-used pieces of equipment. I use it primarily to let me switch between multiple laptops and mini PCs on the same desk. As of 2025, I own and use 3 of them.

## Basics

* Product page: <https://www.caldigit.com/thunderbolt-station-4/>

* M3 MacBook Pro
* M3 MacMini
* M1 Mac Studio
* Surface Laptop 7
* Surface Pro 8

## Note on using it with Windows devices

Whenever one of my Windows computers is plugged into the dock, it shows a "too many USB hubs" warning, but everything still works.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sevenpens.com/drawtab/catalog/accessories/docks-and-hubs/caldigit/caldigit-ts4-thunderbolt-dock.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
