I have the latest version of OS Yosemite (10.10.5) on a very powerful MBP (i7, 2.4, 16GB RAM).
When I right-click on a file in Finder and choose "Open with", "Other", the dialog window is very unresponsive:
- it takes time (minutes) to populate the /Applications folder.
- Scrolling the content of the /Applications folder is incredibly slow, the content takes seconds to move when I scroll the mouse wheel and I spend not less than a minute trying to reach the correct application I want to use.
- When I finally reach the correct application and click on it, it takes 1-2 seconds to highlight the item I selected and another couple of seconds to enable the "OK" button.
This happens every time I select "Open with - Other" and not only the first time.
Is there anyone who can suggest a solution for this problem, it is incredibly annoying. I have never experienced such a weird behaviour on any OS X version.
Thanks.
