Dropbox says OS X 10.10.1 Yosemite update resolves crashing issue, urges download

In the note, Dropbox urges users to download Apple's OS X 10.10.1 Yosemite maintenance update as it resolves a problem with Finder-based program crashes.

OS X Yosemite may occasionally cause some programs to crash when you open, save-as, or first save a file. These crashes are rare but happen when an application, such as Dropbox, uses Yosemite's official Finder integration — and if that program crashes because of this interaction, unsaved changes may be lost.

Apple issued OS X 10.10.1 on Monday to deal with reported Wi-Fi connectivity issues and improve Microsoft Exchange reliability in Mail. The app crashing issue was not identified by Apple in the release notes, nor was it an area of focus for developers during beta testing.

It appears that Dropbox did not need to make any changes on its end to remedy the situation, suggesting Apple's fix may extend to other third-party programs seeing similar crashing issues.
