Just chatted with the developers today and they said they are working on updates for 10.9.5 and Yosemite.
I sent a customer support request on 18 September, and got an almost immediate response, saying that
We're sorry for the inconvenience.
Please be advised that if you have OS 10.9.5 or Yosemite - our developers are working on the update and will make it compatible with the latest versions. And once this update will be released - you'll be notified.
Thank you for your understanding in advance!
Please tell us if you need any further assistance.
Best Regards,
Support Team,
Coppertino Inc.
And nothing since. No updates today. I tried to find out additional support options on the Coppertino website; they seem to be focused on their app Vox. In fact, a support forum is available through the Coppertino page, and
another user of Wallpaper Wizard had posted there asking about another issue. The "Vox Developers" immediately closed the thread, directing the user to the same support email I used.
I'm obviously feeling disgruntled over a paid app being broken for over a week, but I find it curious that Coppertino is willing to take responsibility for Wallpaper Wizard as part of their marketing (see their
Twitter description), but less willing to integrate support into their existing system, leaving us with nothing but an email address for support.
UPDATE: version 1.5.1 is
available for download
