Mike's latest podcast is available:

If, like me, you normally download it using the download symbol under the built in player, and find that no longer works (it may work in Windows) try this link:

If you open that xml file in a browser it should offer a webpage with a link 'download' to an mp3 file. That's what I get in Firefox but it depends on your browser; it may pass it to an RSS feed reader if you have one.

If you end up downloading the xml file itself, look in it for an item like this:
