Following Apple's release of OS X 10.10.1 Yosemite on Monday, Dropbox is sending emails to users confirming that the latest Mac maintenance update solves a rare crashing problem seen with apps integrated with Finder. 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.
