I am running the current version of Bookends on my iMac, which runs Mojave, but I would also like to have it on my Macbook if possible, which runs Yosemite 10.10.5.
I might just be suffering from temporary blindness, but when I go to the 'Update History' page there are no active links to download the listed versions of Bookends. Also, the most recent version seems to be 12.8.5 on that page, but I think elsewhere you recommend "versions 13.2.8 and 13.3.0 work in macOS 10.10 (Yosemite) and later".
Thanks for your help in advance

p.s. I LOVE Bookends. Thank you so much for developing such a great product. I recently bought an iPad purely to run iOS Bookends. I wish I had known about it for my Honours dissertation!
