Hi @stefan, thanks for using Codebook and posting to the forum!
The change in Dropbox support for macOS requiring macOS 12.5 pertains only to the native Dropbox client application for macOS, which integrates the Dropbox service with Finder and other operating system features.
Codebook doesn’t utilize the Dropbox client application. Instead we interface directly with the Dropbox API to provide the Dropbox Sync feature. We utilize their Objective-C client library for this purpose, which still has a minimum macOS version of 10.10.
In summary, the change to the Dropbox client application should not break anything at all for Codebook for macOS.
That said, we will keep an eye out for any problems, and please let us know if you run into any yourself!
