Photoshop CS6 icons sometimes do not appear on Macintosh

Yes, this is a question.

I've been using my trial of Photoshop CS6 Extended for 10 days now. I have run into a peculiar problem - when saving a file Photoshop does not display any sort of icon. No thumbnail, no generic, nothing. It's not a huge problem, I can always open the image but not by double-clicking on the icon: it's just not there.

I'm wondering if anyone else has had this problem and if there is a resolution to it - or is it just a bug? I didn't have this problem with the beta version and I've repaired all permissions on my hard drive to see if that was the problem.

Any help would be appreciated.

Regards,

Clinton

Correct answer Chris Cox

The thumbnails in the open dialog are provided by the OS (as is most of the open/save dialog).  So there is still a problem with the OS creating or displaying thumbnails.

It's not a matter of blaming Apple without reason, just that Apple has an awful lot of bugs in the OS that don't get fixed very quickly.

Here we know that the OS is responsible for the thumbnails, that clearing the OS cache of thumbnail and metadata fixes it for some people, and that even after that the OS can't always draw the thumbnails when it is supposed to.  I have no idea why that would be worse in some applications than others - but the OS is clearly failing to draw thumbnails, and that's not something that Photoshop has any control over.

It could be something like messed up registry entries (or file associations on MacOS), or a bad thumbnailing program, or problems interpreting transparency, alpha channels, etc.  So we're going to need more information.

Which OS version are you using?

Do you have any third party utilities that create thumbnails for PSD files or other image formats?

Do the files include transparency, or alpha channels?

Some of them are jpg, some psd with transparency and alpha channels, some png, some tif, etc. I just installed an SSD and ran diagnostics on it, repaired some permissions (again) and verified and repaired the drive. Now some of my previously 'lost icons' are showing up, but not all. I'm on a MacBook Pro (late 2011) running OS 10.7.4.

Thanks,

MacOS does have known bugs creating thumbnails for files that contain alpha channels (some intern at Apple confused them with transparency), so that could mess up some files.

But JPG files shouldn't be a problem, or PNG.

Hey Clinton,

Do you have some kind of Alpha Masks used in the Photoshop images by chance??

<< Photoshop does not contain anything called an "alpha mask">>

Thanks
