Note that the new Dropbox API requires OS X 10.10, so I've bumped the minimum version that MacDive requires. Apologies for any inconvenience. The number of users <10.10 is very small. I can build you a separate version of MacDive that has no cloud syncing (iCloud requires 10.11+) if necessary.
If you have any issues with syncing, please just disable and then re-enable.
New Features:
- Added ability to filter AutoAdd by a diver, so only their dives are considered.
 - Added Purchase Date column to Gear Table.
 - Updated Dropbox API to V2.
 - Improved DM5 database import.
 - Improved UDDF import.
 - Minor UI improvements.
 - Minor optimisations.
 - Minimum version requirement is now OS X 10.10.
 
- Fixed bug where notes could disappear if a sync started while writing them.
 - Fixed issue where some alarms were drawn at a slightly incorrect position.
 - Fixed issue where downloading very short dives from a Petrel 2/Perdix could fail.
 - Fixed various issues reading data from a range of devices.
 - Minor bug fixes.
