Is the new Mac update mislabeled as version 4.10.2?
When Coollector version 4.12.4 came out, my copy of 4.12.3 prompted me to update. So I let the installer run, the app relaunched automatically—and it prompted me to update again. Still had the old version.
So I tried downloading the current version from the link on the website. Except it was a few version old: 4.10.2. Out of ideas, I launched 4.12.3 and let it download the update again, then deleted the app before going through with the install. And that seemed to work, no more update prompts. Except it gave me 4.10.2 again.
