I've extracted the key from your text: `free for mac instal PuTTY SSH 0.79`. It seems like you're looking to install PuTTY on a Mac.

To help you with that, I'd like to provide some guidance. Since you mentioned installing PuTTY on a Mac, it's important to note that PuTTY is primarily designed for Windows and Unix platforms. However, there are alternative ways to use PuTTY on a Mac:

1. Install PuTTY on a virtual machine or boot camp: You can install a virtual machine software like VirtualBox or Parallels and run a Windows operating system inside it. Then, you can download and install PuTTY within the virtual environment.

2. Use an SSH client for Mac: There are several excellent SSH clients available for Mac, such as:

- Termius

- MobaXterm

- SecureCRT

These clients provide similar functionality to PuTTY and are designed specifically for Mac.

3. Use a third-party software that supports PuTTY on Mac: There's also a software called PuTTY for Mac that allows you to use PuTTY on your Mac by running it through a Windows emulator.

Before proceeding, I recommend researching each option in more detail to determine which one best suits your needs and preferences.

Please let me know if you have any further questions or if there's anything else I can help you with.
