Bind NSTableView to array of dictionaries in user defaults

In an OS X app, I wanted to bind a table of objects, each represented by a dictionary, to an array of dictionaries in user defaults. So I bound the Content Array of the array controller to the 'values' of the shared user defaults controller with an arbitrary key path, which pleasantly became th

Progress bar problems on server persist

A while back I started a thread about NSProgressIndicator locking up on a Mac with no monitor. The suggested fix was to change them to use timers instead of threads for animation. We thought that fixed it, but no, it's back. Any other ideas on how to fix this? We put in a workaround to not show

Re: Where are my bytes hiding?

Extended attributes have been part of the Macintosh operating system in a few different forms since 1984. Up until Mac OS 9, the only alternative was a resource fork. In Mac OS 9, named forks were introduced, although only data and resource were practically available, and under the Mac's Unixifi

Re: Setting a prefs value at quit time

Isn’t there a sudden termination option to allow this for this exact purpose? Or would there be an application delegate method that would allow the application to quit? When a quit is issued, make sure that the can quit returns NO and after the prefs are written, change that value to YES and
