I'm happy to help you with your request!

You're looking for information on how to download the Tor 12.5.5 browser, specifically for a Mac system. Let me break down the relevant information from your provided text:

1. The latest version of Tor Browser is 12.0.5, but there's also an option to download version 12.5.1 (win64 or win32) and other releases mentioned at the end.

2. There's no direct mention of a Mac-specific release for Tor 12.5.5, but you can try downloading the latest stable version from the official Tor Browser website.

To clarify, here are the steps to download the Tor Browser:

1. Visit the official Tor Project website: 'www.torproject.org'(http://www.torproject.org)

2. Click on 'Download' at the top right corner of the page.

3. Select your operating system as 'MacOS'.

4. Choose the latest stable version, which is currently 12.0.5.

If you're interested in downloading an older version like 12.5.1 (win64 or win32), you can try searching for it on other reputable download websites or repositories.

As a side note, Microsoft Defender might flag Tor Browser as suspicious due to its nature of providing anonymous browsing and security updates. You can either configure your Windows Security settings or disable the alert if you're sure it's safe to use Tor.

Please let me know if there's anything else I can help with!
