Mac PuTTY Install & Logging

I need PuTTY installed on my new MacBook and set up so that it only keeps logs for specific connections I choose, nothing more. Please handle the complete installation—Homebrew, MacPorts, or a signed native package is fine as long as it runs on the current macOS version—and verify that SSH sessions open without errors.

Once PuTTY is in place, adjust its settings so:

• Logging is OFF by default.
• I can flag a session to create a log, and only that session writes to a file.
• The log location is clearly documented (any convenient path inside my home folder is fine).

Acceptance criteria
1. A short walkthrough or screencast shows installation steps and the exact logging option you changed.
2. I can connect to two test hosts: the one marked for logging writes a file, the other does not.
3. No additional configuration files or permissions are required for future use.

Let me know how soon you can deliver and any questions you might have.
