My Canon EOS 400D isn't reconized after 10.5.5 (HELP)

Apple aren't "working on this" as it's a local problem to you, there have been no other reports that I have seen, and certainly none on here.

Have you tried putting the card into a USB card reader?

Canon cameras don't mount on the desktop. It's a 'feature' of the brand.

Try download the 10.5.5 combo updater and re-apply it.

It's a long shot but try deleting the iPhoto preference file, com.apple.iPhoto.plist, that resides in your User/Library/Preferences folder and try again.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

I'm having the same problem. Ever since 10.5.5, the memory card access light flickers when I connect the camera to my Mac so at least there's some sort of recognition event, but after a few seconds it just gives up and I can use it as though there's no computer attached.

I'm gonna swing by my local Mac store and I'll let you know if I find anything out.

Same problem here. Connect the camera, switch on, Aperture just starts then hangs.
No camera shown in finder,

I downloaded to my windows laptop then burnt to disks and then transferred to the Mac.

I formatted the card in camera which seems for the moment to have fixed it, but for how long....

If you've applied the latest RAW compatibility updater, 2.2 then download and reapply the previous updater, Digital Camera RAW Compatibility Update 2.1. That's reported to have fixed the problem for some users.

OT

Might be a stupid question but how would I know if I had applied the latest updater, and if so when, as this problem only seems to have started since last week and I don't recall any other recent updates....

Look in the HD/Library/Receipts folder for any files like RAWCamera.pkg, or RAWCamera2.1.pkg or RAWCamera2.2.pkg or something close to that. If you have one with 2.2 in it reapply the 2.1 updater.

Or, if you use Software Update from the System Preferences open it and look in the Installed Updates section.

Just like to say I am having exactly the same problem with my Canon 400D and it has happened since the last updates. I will try the advice on here and see what happens but I would say it is definitely a prob with Apple and not my end.

I have installed the 2.2 update..... Trouble is I can't figure out how to remove it to reinstall the earlier one 🙂

I have tried uninstalling 2.2 and reinstalling 2.1 but it doesn't like it. Also I removed the iphoto plist in preferences hoping this would help but again no joy. It really does seem that something in this latest update has totally messed up my routine of importing my pics from my canon 400D or my card reader. Any further ideas? How does one revert back to the last update of leopard etc without losing any pics added since?

How did you go about uninstalling and reapplying the 2.1 updater? All you need to do is remove any receipt with RAWCamera in the file name from the HD/Library/Receipts folder and reapply the Digital Camera RAW Compatibility Update 2.1.

Won't work for me either. I removed all receipts with RAW in them but the update still says it won't install as a newer version is already installed. Even after a restart. Is there something else I need to remove? like a plist?

The article just recommended reinstalling the 2.1 updater. It was at either MacInTouch or MacFixit but I've not been able to find it. There is a way you could downgrade but it involves an Archive and Install (while keeping the user and internet settings) and then apply the various system, quicktime, iLife support and other updates to the version you want. A lot of work but a last ditch fix. If you do something like at, either now or in the future, I recommend you download the latest updaters from the Apple Downloads page and install them manually. That way you can get the combo system updaters and only those others that you need or want.

UPDATE: I found the posting at MacIntouch:

"TS Low
There is a serious flaw for many users with the latest MacOS update 10.5.5 and the Digital Camera RAW Compatibility Update 2.2 which followed shortly thereafter.
The problem causes Aperture and Image Capture (and some say even iPhoto) to hang and sometimes crash on imports. About a dozen threads sprang up on the Apple Support Forums immediately after the updates came out. Critically, some of the newer camera models are affected by the RAW update, so instead of enabling, the update is crippling image import.
Apparently someone took an afflicted system to an Apple Store where the baffled staff got in touch with the mother ship directly and were informed that the problem was known and would be resolved by yet another update soon. The Apple engineer's are on it, but frankly, this is very poor quality control. Apple is already ridiculously late in supporting many models of camera compared to Adobe. Apple's photography support has been found wanting lately and could be evidence of a company stretched too thin.
In the meantime, some users have found respite from the problem by downgrading to Digital Camera RAW Compatibility Update 2.1 found at:
http://www.apple.com/support/downloads/digitalcamerarawcompatibilityupdate21.htm l"

I don't know where Low got the info on it fixing the problem for others.

Removing my receipts didn't work either, I still get the message "This update does not need to be installed. A newer version of Raw Camera Support is already installed."

Sadness.
