I press M in aperture but nothing happens and it makes sound

Maybe you were in "Quick Preview Mode".

Then you cannot edit or toggle between original master image and edited version - many controls will be disabled.

To turn on/off Quick Preview Mode press the button with the square and the three lines looking like a dust tail.

Is there anything else that is not working? Can you edit your images?

Have you inspected the command bindings for the keyboard shortcuts?

If not, use the "Aperture > Commands" menu in the main menu bar and select "Customize".

In the keyboard viewer that will be shown press the "M" key. What do you see?

Does it still show "No Modifier : Show Original"?

If not, repair the key binding by dragging the "Show Original" command to the "No Modifier" place.

em, you can't modify m shortcut, it's set to show original.

If the "M" shortcut it is set correctly, no problem.

But you should be able to edit the keyboard shortcuts by dragging menu items to the keys in the commands editor, like this: (you cannot edit the default set, but Aperture might be set to use a custom command preset). This shows my "M" bound to "Export Metadata".

We occasionally see here, that the keybindings get changed, if somebody installs a program, that hides Aperture's keybindings and replaces them by different ones. That can be repaired in the System Preferences > Keyboard.

guys, same thing happens again. by the time i wrote this message it works again.

Try to narrow the probem down.

• Does it only happen, when you are working in one particular Aperture library or also in other libraries? Try to create a library for testing.
• Does it also happen, when working from a different user account?

😮 oh, no!

After I changed the "M" key back and forth, it stopped working! Now I am seeing exactly the same problem as you: Beep, beep, beep when pressing "M" on any image.

- Quitting Aperture and relaunching does not fix it.

- Rebooting does not fix it.

- Switching between command sets does not fix it.

- Switching between Libraries does not fix it.

- Toggling "Preview" mode does not fix it.

- Clearing Aperture's caches does does not fix it:

~/Library/Containers/com.apple.Aperture/

- In my second user account I see the same, even for a new Aperture Library in the second account "M" does not work.

What is weird: The command presets are missing in all libraries: Are they no longer used?

~/Library/Application Support/Aperture/Command Sets/ is empty

/Library/Application Support/Aperture/Command Sets/ is empty as well.

But all other keyboard shortcuts are working. Only "M" does not.

Conclusion: It is a system wide trouble with the "M" key, and since it happened directly after I played around with Aperture's keybindings, it is more likely software related than hardware related - probably a globally stored setting in the system library and configuration files, or in the Aperture application bundle, but where?

Or a hardware setup problem - PRAM, SMC, …

I'll experiment a bit - if you find a solution, let me know 😟

by the time i wrote this message it works again.

Three hours later, and the M-key is working again all of a sudden. In the meantime I did nothing but use Mail, Safari, Firefox, iPhoto, Calendar, Preview, and GarageBand parallel to Aperture.

In Aperture I deleted some albums defined at Library level, changed the sorting of projects, and accidentally tried to open a slideshow that been created in iPhoto.

Do you use iPhoto and aperture together?

how did you change the m key back and forth?

And is it wokring now?

how did you change the m key back and forth?

Aperture > Commands > Customize

Then I duplicated the default command set and dragged the "Merge Projects" command to the "M" key.

Then I saved this set, played around a bit with it, reassigned "Show Original" to the "M" key, saved again.

And switched back to the default set.

And is it working now?

Frank, are the posts still not showing for you? In my previous post I said:

Posting, just to make sure the previous post will show.

I am really not sure what fixed the "M" key. I stopped the trouble shooting, after I tried all the fixes listed above.
