    Hi - thanks for this. I found Time Machine far too "non-intuitive" to use to delete back-ups (like Carrie I didn't see the "gear icon" and am just presented with multiple windows and no obvious way of selecting or deleting) so opted for the Finder method. Question - why did Time Machine fill up my external HD - it's supposed to delete old back-ups to allow space for the new one isn't it? Anyway, I have back-ups from 2016, 2017 and much of 2018 to delete! 2016 seemed to work and I could empty the trash. 2017 was counting up to over 1m items and is now counting down as it empties. In both cases it pauses every now and then to tell me it can't complete an operation because something is "in use" including Library, System, Macintosh HD, Core Service and - I've just selected Skip each time and let it continue - is this the right thing to do? Hard to operate a computer without using the HD I would have thought!

    Option 1 does not work. When I enter the time machine app there is no gear icon to select. Why does Apple make it so hard to manage our own storage? Grrrr.

    I used "method2" and now Finder won't let me empty Trash. I now have 2Tb of backups in Trash and no way to get rid of it...
