Random jpg files not displaying on 10.8

I have an iMac running 10.8, a pre upgrade image created using super duper for this same computer and a mac pro running 10.7. I'm getting random pictures that have not changed for years showing "unsupported image format" in Aperture and they also don't display in preview or finder. Same picture (stored in the super duper backup) will show without issue on the mac pro running 10.7. I haven't seen a pattern with files it supports without issue and those that don't but there appears to be a bug with mountain lion. Side note, I encrypt the hard drive for the imac and SD backup using Apples encryption software. Has anyone else seen this or know of any bug? Nothing came up when I was looking around.

iMac, OS X Mountain Lion

Welcome to Apple Communities

Go to System Preferences > Security and Privacy > FileVault and turn it off. Then, see if the problem happens. If the problem doesn't appear, http://www.apple.com/feedback

Did some more testing. File opens in crome and firefox with no issue on the imac running 10.8, picture does not open in Safari, Aperture, preview or finder. It's certainly a bug and not encryption related.

I did a full clean install of 10.8. Didn't load any custom software, jpg still not showing in finder or preview. Downloaded firefox and picture comes up clean. Picture also some up clean on 10.7 macpro.

Open Preview and open the jpg there. Open Disk Utility and repair permissions

As stated above, preview doesn't work. permission repair didn't change anything.

Below are some screenshots of what I'm seeing. The first is opening the file in preview. The second is opening it in Firefox.

I think I've noticed the same issue. For example, pretty much every jpg that's been recently posted to this guy's blog -- http://www.youhaventlived.com/qblog/ -- no longer shows up in safari for me, but is fine in chrome / firefox. If I download one of the afflicted jpgs to my computer, finder won't show a thumbnail for it (it just displays the generic "jpg" icon), quicklook won't show it, and preview says the file is invalid. Meanwhile, other apps (such as photoshop, and the aforementioned web browsers) will load these jpgs fine... and my older mac (still running snow leopard) has no problems with them either.

Must be some particularly obtuse/slightly-non-standard jpg format that 10.8 isn't happy with.

This is exactly what I'm seeing although I never noticed it on websites as well. Great example of the issue, thanks.

Hi,

same here with JPEGs from Corel X4. The jpg files work without problem on Photoshop, Graphicconverter, Firefox and on Windows Vista, XP and also on LION.

But on Mountain Lion Finder, Preview, Safari do not show it.

Any new suggestions?

Greetings

Nothing yet. I have two bugs open with Apple. It's certainly a bug. If you have another product that can open and save, it will fix the issue. I was able to do that with lightroom 4.

After 9 months this is still a bug with 10.8. The only work around I have found is to download GIMP, load the file and export it again. I have had no response from Apple for the two bugs I created for them.

Has there been any progress on this issue?

I just ran into it today, where a JPEG uploaded to my site does not display in Safari but displays fine in Firefox, Chrome and Opera.

I could NOT open it in "Preview" - but was able to use ImageMagick to "convert" the file to a jpeg (*same extension/file type*) which made it viewable by Safari.

Apple support did come back and "resolve" the issue. What I found was it fixed most of my jpegs but I still see pictures in aperture from time to time that are not displaying correctly. I still need to update the bug report and notify them that they still have issues and send them an updated jpeg with problems. I would suggest you open a ticket with them as well as it appears they haven't fixed everything yet. I'm currently on the latest version of 10.9 and 10.7 seems to be the last solid OS with regard to jpeg imaging.
