High Sierra photo editing slow

I've followed the instructions in this topic and installed nvidia drivers (Web drivers & CUDA) on my Macbook Pro (10.13.5) and I have noticed a lot of improvement.

I am having the slow editing problem with my 2011 iMac with AMD Radeon HD 6770M and my wife has similar problems 2013 MacBook Air with Intel HD Graphics 5000. The Apple Photos specialist I spoke with was experiencing freezes and slow editing in Photos on her own Mac, which was most likely a new computer. She was focused on the specific camera versions that were generating the problem raw files. I have many different raw files from older cameras that cause no problem at all, and of course no files from any iPhone or iPad cause the issue.

Here it is, June 3, 2018, and I'm having the same problem after updating to High Sierra finally. It's a shame almost EIGHT MONTHS have gone by since your post and there's not been a fix. I'm running a 2015 iMac and I'm able to edit a few photos and then Photos quits on me. I have a ton of photos to edit for a project and it's going to take forever!

Now that Apple has announced MacOS Mojave, I suggest that everyone having the slow editing problem with Photos consider signing up for the public beta once it becomes available. In the event that Apple never fixes this in High Sierra, there is always a chance that Mojave will address the issue if enough people provide feedback.

Just a caution: Only people who have a Mac that they can dedicate for Beta testing should install the beta version. Betas are not as stable as the official release and you may be in for bad surprises. It would be risky to install a beta version on a Mac that we urgently need for our daily work or our only computer.

The second problem with a beta release is, that their is no way to find out which features have been dropped and are no longer supported the new system version, or which applications will be incompatible, because nobody will be allowed to post results from Beta testing publicly. Do not jump on the Mojave band wagon early, before you know, if Mojave will still support your most important applications and devices.

When you install beta software, you need to realize that you are TESTING it, not using it! Never rely on a beta OS for mission critical work. Install on a spare computer, external boot drive or partition. You will be contributing your own personal time as well. But, participants can help solve this problem and other issues for many other users. I find that the second problem léonie mentions is actually the best reason for me to run the public beta, since I can identify upcoming issues of incompatibility and then decide NOT to install the official release until they are fixed. I never converted my Photos library to version 3.0 prior to installing the official release of High Sierra because I didn't want the two libraries to diverge, so I got blind-sided when I did install the official release of High Sierra and converted the library. This time I will test Photos to see if the problem is solved. Sadly, I will be unable to discuss the issue in this forum, because of the beta software license.

Installed 10.13.6 and Photos has been updated to 3.0 (3291.13.210). Unfortunately, there has been no fix for my problem. Editing raw photos from my Olympus OMD EM-5 Mark I is still slow and causes the same freeze while editing with retouch tool or DXO Optics Pro for Photos. Since my 2011 iMac will not be able to run Mojave, time is running out for a fix in High Sierra.

Yeah I’m hanging out for an update! Totally stalled on all my photo retouching etc☹ It’s a shame Apple doesn’t engage in these support group conversations...

Please Apple can you tell me my options

Apple is not here - this is strictly a user to user forum with experienced users helping others

Go into your local Apple Store or contact Apple

Hi,

Just wondering if you have heard anything back about this problem...?

Yes it is a shame. Surely they must have people keeping on top of all these sorts of things and working on a fix.

Why did they release this “wonderful” update when photos runs as fast as malassas?? Come on Apple! That’s why you have Betas! This OS is NOT ready for release. My Photos editing is worthless!

Mine too .. got a top spec iMac end of last year and its very slow in Photos editing mode. Sorry but this should not be in a new install.

I have the same effect on a MacBook Pro (15-inch, Early 2011). The Retouch is particulary annoying as I have to post-process a lot of scanned analog photos with this function.
