I recently encountered the problem and submitted a bug report. The response was the issue was an operating system problem, not a MATLAB problem, which means that there probably won't be an official fix. There are several possible workarounds.
- You can switch over to an alternative file selector, such as uipickfiles
- You could copy the private function uigetfile_deprecated (located in the uitools directory) to a convenient location on your machine. NOTE: this function may have dependencies...
- You could edit the uigetfile function (or a renamed copy) to always call uigetfile_deprecated on Macs.
- You could try using the undocumented "feature" command to use the old dialog style
In the long term, option 1 is probably the best bet. Maybe someone can figure out what Apple did in the last release that drops dialog titles...
