Files no longer open in their default application, though using the program's 'Open' function works fine.Īpple Support Discussions user 'marminio' reports: After upgrading to Snow Leopard these users report that they experience the problem intermittently. Some users are experiencing an issue in Finder where files will not open when double-clicked. The article highlighting some of these issues follows:
Perhaps the issues we have been seeing relating to Finder's inability (at times) to open files is related to this change (or a bug in it). Now, in Snow Leopard, users and developers are complaining that the Unix way is being allowed to run roughshod over the Mac way. Since the very first day of the very first version of Mac OS X, there has been an uneasy detente between the Unix way of binding documents to applications and the former Mac way, inherited from the early days of the Mac OS. The relationship between a document and its owning application is called a preferred application binding. This change is new to Mac OS X 10.6 and greater and signals a fundamental change in a long-standing Mac programming code. Matt Neuburg at TidBits explains that Apple has officially documented that Snow Leopard's Launch Services no longer considers a document's embedded Creator Code when determining which application to launch when the file is opened in Finder.
