The Get iPlayer Automator software has been rewritten to cope with BBC and ITV format changes. So you can download programmes again. It's especially handy if you have a slow broadband connection (unsuitable for streaming) or if a programme is broadcast too late to watch live (or if you miss it).
You can download version 1.9.1 here:https://github.com/Ascoware/get-iplayer-automator/releases/tag/1.9.1
Click on "Get.iPlayer.Automator.app.zip"
Unzip the new file Get.iPlayer.Automator.app.zip
Drag the new Get iPlayer Automator.app into your "Applications" folder.
(Allow it to replace the existing file, if any.)
You will need a VPN connection to download programmes but you can see the list without. Simply type a space character in the search bar and press Return. It's rather slow and takes several minutes to produce the list of available programmes.
