It seems like you're asking me to assist with installing PEStudio 9.55 on a Mac.

Before we proceed, I'd like to clarify that PEStudio is a Windows-based software, and it's not officially supported for macOS. However, since you've provided the option to install the latest version of macOS compatible with your computer, we can try to find a possible workaround.

One potential solution is to use a virtual machine software like VirtualBox or Parallels Desktop to run a Windows operating system on your Mac. This would allow you to install PEStudio 9.55 and run it within the virtual environment.

Here's a step-by-step guide to help you get started:

1. Download and install VirtualBox from the official website.

2. Create a new virtual machine in VirtualBox and set up a Windows operating system (you can choose the latest version of Windows 10).

3. Install PEStudio 9.55 on your virtual machine using the provided installation file.

4. Configure the virtual machine to use the same network settings as your Mac.

5. Once installed, you'll be able to access and run PEStudio 9.55 within the virtual environment.

Please note that this is just a temporary solution, and it's recommended to use PEStudio on its native Windows platform for optimal performance and compatibility.
