I've identified the key phrase as 'DisplayFusion Pro 10.1.1 for apple instal free'.

Based on the provided text, it appears that DisplayFusion is a software application that helps manage multiple monitors and provides features such as:

* Multi-monitor taskbars

* TitleBar buttons

* Customizable hotkeys

The text also mentions that DisplayFusion can be used with one monitor or multiple monitors, and that it's available for free download.

Regarding the installation on an Apple device, I found a Chocolatey package manager command to install DisplayFusion Pro 10.1.1 portable version:

`choco install displayfusion.portable --version=10.1.1`

However, please note that DisplayFusion is a Windows application and may not be compatible with Apple devices directly. You might need to use an emulator or virtual machine to run it on macOS.

Additionally, the text mentions that the free license is only usable for personal and non-commercial purposes. If you're looking for a free version for commercial use, you might want to explore alternative options.

Let me know if you have any further questions or concerns!
