Hello DPP users!

Two weeks ago I got my first Mac - a Mac Pro. I've upgraded the installation
to 10.5.2 right from the beginning. I also installed Canon's DPP 3.2.0.6
and it worked then. Now, some days later, I have trouble starting
DPP because it shows the spinning wheel and literally takes *minutes* to
start.

/var/log/system.log shows this:

Using "Spin Control" I got a backtrace of the hanging DPP process. The trace indicated
that the process hangs in the lstat() syscall. I used the following DTrace script to find
out which file it is lstat()ing:

It turns out DPP hangs because it lstats files in the /net directory! Sample DTrace output:

barton is an (offline) host in my LAN. /net is a autofsd/automountd
directory according to /etc/fstab:

When the DPP window finally appears on the screen after several minutes I see
"/home" and "/net" directories in the folder sidebar on the left. The shell command
"ls /net" hangs, too.

Does anyone know how I can prevent this strange behaviour?

I'm sorry if this is a stupid question but I'm new to the Mac...

Do you use MacFUSE? Are your images stored on a remote host? From your ystem log, DPP is looking for a remote file system.

I must say that I haven't installed the last version of DPP and only have very limited experience with previous versions.

No, I don't use MacFUSE. All files are local and I never accessed a remote filesystem from
DPP.

I have VMware Fusion 1.1.1, however. But as far as I remember the DPP hangs happened
before I installed it, too.

OK,
I launched the latest version of DPP installed on my Mac (3.0.0.4) and it also spent an eternity trying to scan /net and trying to acces hidden.local. I didn't bother to install the latest available version.

It might be an incompatibility between Mac OS X 10.5.2 and DPP. FWIW, I also tried on a dual G5 (running 10.5.2) and results are very similar.

Thanks for testing!

If you absolutely need DPP, you can try to install it on your VMWare Windows partition until Canon comes up with a working solution.

DPP 3.2.0.6 is working fine on my MacPro running Leopard 10.5.2.

Troubleshooting DPP:

The preferences file for Digital Photo Professional may be damaged.

Quit any applications that are running, delete the preferences file from the [Preferences] folder using the following procedure, and then restart Digital Photo Professional.
Open the hard disk drive where the system is saved > the [Users] folder > Folder for the logged in user > the [Library] folder > the [Preferences] folder and then delete [com.canon.Digital Photo Professional.plist].

I already tried to delete preferences without success. It might be important to note that I had previous versions of DPP and installed updates. If I find the time, I'l install a fresh version to see if it's better.

I also tried to delete the preferences file without success. And I did not upgrade. DPP 3.2.0.6 is the first version I installed on my Mac Pro.

jerryrock, is your computer on a LAN? Did you ever enable Windows file sharing before? What happens if you execute "ls -l /net" in Terminal? Do you get an instant result (directory listing) or does it hang?

My computer is connected to a Linksys Wireless router (via ethernet cable). I have not enabled Windows file sharing.

I use hard drives physically installed in my system, so the terminal command is pointless for me.

I have DPP 3.2.1 on my Mac Pro running 10.5.2 and it doesn't work.

The application will start (takes a while as it probes every disk attached to the system), but when I select a folder full of RAW files I don't get any thumbnails. Double clicking on the photo placeholder gives me a SPOD.

Ah well, Lightroom and Aperture work well enough -- but if I wanted to shoot tethered with the 1Ds Mark III I'd be SOL. Good thing I'm a landscape guy not a studio guy I guess

After noticing that DPP 3.3 probably won't support 10.5 either I decided to give this a 2nd try. I now found a workaround for the problem:

1. Comment out the following line in /etc/auto_master:


2. Reread the config with


Now DPP starts normally again and the command " ls -l /net" doesn't stall anymore.

If I do not comment the "/net" line every process which accesses the /net directory (like DPP) will hang for minutes (SBBOD).

Caveat: I don't know if this will have any bad consequences on the rest of the system.

Thanks for the fix. I thought of doing something along those lines but since I only use DPP very occasionally , I gave up. I filed a bug at Apple, naively hoping that they can contact Canon.
