P: Edit In External Editor does not work/function

Off hand, I would try a repair install of CS6. That normally restores the link.

Further note:

Lightroom was purchased as a standalone product prior to the release of CS6.

Photoshop is a CreativeCloud product.

All Adobe products were a fresh install on a MacBook Pro Retna early in July. At that time the OS X version was 10.7.4. When Mountain Lion was released, I upgraded to the new version.

All updates have been applied to Photoshop CS6 Extended, including ACR 7.1.

When I open CR2 (Canon 5D mk III RAW ) files in Photoshop it opens into the ACR dialog correctly. However, to accomplish this in the Mac version I have to either use File Open or DRAG the file from mini-Bridge. Double clicking mini-Bridge CR2, DNG and PSD files does not open the image in Photoshop Mac.

Double clicking CR2, DNG and PSD files in Bridge correctly opens the image in Photoshop.

All this works correctly from Lightroom and mini-Bridge on my Windows version.

Mac OS X 10.7.4 or 10.8
Lightroom 4.1
Photoshop CS6 Extended

Selecting a RAW file in Lightroom and clicking on "Edit in Photoshop CS6" launches Photoshop but the image does not appear in Photoshop.

Selecting a JPG file in Lightroom, clicking on "Edit in Photoshop CS6" then selecting "Edit with Lightroom Adjustments" launches Photoshop but the image does not appear in Photoshop.

Selecting a JPG file in Lightroom, clicking on "Edit in Photoshop CS6" then selecting "Edit a copy" launches Photoshop with the image in Photoshop.

I have tried deleting the Photoshop plist file in the user library and relaunching Photoshop. This did not cure the issue.

On Windows 7 x64 I do not experience these issues.

I'm really not sure if this is a LR 4.1 or a PS CS6 issue... I am trying to 'edit in Photoshop CS6' from LR4.1 but when I click the button, nothing happens.

Serious issue for me so hoping someone has a fix.

Cheers

With Lightroom 4.1 Photoshop Elements 10 is now starting, but it didn't open the foto selected in Lightroom. System is Mac OS X 10.7.4

I can't understand why Adope is not able to fix that problem. Apparently, many users had that problem! Until now it is not completly solved...

I did download 4.1 LR. That fix most of the problem. However on some photos, even recent ones, I can not use my external editor in Photoshop Elements. How do I try "the registry fix?" Richard

Did you try the registry fix?

A slected photo in LR4 can't be exportet for further development in Adobe PS10. I have posted this problem but no answer from Adobe until now!
