Help please.

I have an Apple iMac G5 with 2.5 gb memory. Run Leopard.

Last Saturday I received a brand new sealed version of Aperture 2 as a gift. Installed it and did the upgrade to 2.1.

My problem as follows.

Tried to adjust approx 100 RAW images, things went ok at first, however very slow, after 10 images I clicked on the next image in the browser. In the process of adjusting, it suddenly went black in the main screen. This happened intermittently to the rest of the images along with some images looking like a dark black negative. Subsequently just clicking on some browser images they would immediately bring it up black or with negative look in main screen.

The only way I can get the image to come up correctly is to get out of Aperture and back in again. Then the same events happen all over again.

I put some jpegs on and got through adjusting 60 and then the same events happened.

I removed Aperture and downloaded the trial, entered my s/n and tried again. Same situation.

Contacted Apple, tech rep stated never heard about this problem before, must be a computer problem. Maybe, however Aperture 1.5 worked fine. iPhoto 8 works fine. Photoshop CS2 works fine, as does everything else on this iMac. All worked great with Tiger and now with Leopard.

Does anyone have any idea what maybe causing the problem ? I am at my wit's end !!!!!!!!!!!

Thanks for the help,

Max.

Hi Max -

I asked Ellen Anon, author and Aperture expert (see her blog posts on the Inside Aperture area). Evidently this is a known bug:
"Actually I posted a bug about this on the Aperture O'Reilly forum last week. I've had the same thing happen after making a lot of intensive adjustments. It's a memory issue and Apple Aperture engineers are aware of it. The work around for now is to relaunch Aperture. However it also helps to adjust the images with the Retouch tool first and then follow the order of the adjustment tools in the Adjustment panel."

So, the good news is you're not alone and it's being looked into.

I had this problem, but once ALL the previews were done loading it worked fine

I have the same problem. On top of this, I have lost the histogram in the Levels display, and frequently the main histogram blanks out.

(see screenshot here: http://www.snowhenge.net/pblog/product-rev...re-sluggi.html)

Very, very frustrating....

A year later and the "black screen" problem still exists evidenced by multiple posts on various forums without even an inkling of information from Apple regarding this bug. How can Apple ignore what appears to be a major issue with a "Pro" app?? In my own personal experience, i very seldom can adjust more than 3 or 4 NEF raw files without this dreaded bug showing its ugly self. Often times, the "black screens" are preceded by my adjustment sliders doing absolutely nothing when moved. Once that happens, the black screens are right around the corner forcing an application restart that seldom fixes the problem for any useful period of time.

I've run into the same thing. It happens very intermittently for me. Every once in a while an image, always one I have made adjustments on, will black out in at least one of the viewing modes, sometimes all three. This happens on RAW files from at least three different cameras (D70, D300 and D90, all Nikon though) and with all kinds of adjustments.

A memory issue makes sense but doesn't really help with correcting it. I have found that Aperture, in general, seems to have some memory handling issues. I will also have a single image get stuck in the viewer from time to time. As in, I am in filmstrip view and I can see the select moving from image to image but the large view stays stuck on only one.

Maybe when the next version comes out I will think about switching back to Lightroom...

I agree...it doesn't help at all. Unless Apple engineers redesign the programs dependence on GPU processing, the problem will continue for owners like me who have underpowered GPUs. The black outs are bad enough in my experience that I've reverted back to my former work flow of Photo Mechanic and Capture NX2. Camerabits has stated they will be adding image cataloging features to PM and if it's anything near the quality of PM, it should be a strong contender in the DAM field.

I think a memory issue makes sense but doesn't really help with correcting it. I have found that Aperture, in general, seems to have some memory handling issues.
