I don't know if other people have notice this in Yosemite:
With a file in Finder in focus, when you move the cursor to "Open With" entry, whether from context menu or menu bar -> File, a "Fetching..." subentry appears.
A moment later, the usual suspects show up, as they did in previous OS X versions.
This behavior, I assume, is supposed to be an improvement. Since /Application/***.app/Contents/Info.plist is live-fetched, an user no longer need to reset LaunchServices for related changes to appear. This is my conjecture.
However, this causes a problem for me. I create keyboard shortcut through applescript or BetterTouchTool to invoke Menu Bar -> File -> Open With -> Certain App.
This way I programed FN+SHIFT+1 to open the file with TextMate, FN+SHIFT+2 for Writer Pro, etc.
The 1) need for cursor over "Open With" to trigger fetch, and 2) the delay in fetching cause my scripts to be invalid.
I was able to verify this theory by: 1) Right clicking a file, 1) Hover over "Open With" entry, 3) Wait for the submenu to fetch, 4) Click outside the Context Menu to have it disappear, 5) and invoke the keyboard shortcut.
And the shortcut worked.
So these are my questions:
1) Obviously, can I revert to pre-Yosemite behavior?
2) Does anyone have clever ways to open a file type with multiple apps on demand cleanly and efficiently?
So far, I have one workaround, that is to create a Automator Service. Here is an example with TextMate:
I can run this without delay through 1) Menubar -> Finder -> Services -> Open With TextMate, 2) top level of the context menu, or 3) a keyboard shortcut if I choose to.
This comes with two caveats:
1) The items received into the service have to be in the broadest definition possible, e.g. files and folders. Finder doesn't recognized, for example, .plist files as documents. If you set the service to only receive documents, Open With TextMate would not show up when you want to use it on a .plist file.
2) Because of (1), this menu entry shows up on every item in Finder. It's innocuous enough if there is only one or two custom entries. If there is six or seven, this group of items is going to take over the context menu.
