High Sierra photo editing slow

Adding my voice to the conversation. I'm having the same issues. Once I upgraded to High Sierra, not only is Photos almost unusable...but when Photos is open my whole computer freezes up. iMac with fusion drive 8gb ram. Not a new computer but it runs like slower than my 12 year old MacBook (yes it still runs!)

I'm going to take back what I said about saving each photo edited prior to moving on to the next photo helping to avoid crashes. In the past two evenings I've had two crashes while keeping my SLOW processing rate and saving as I went along.

I shoot nearly exclusively in RAW format. For others reporting this problem, are you working with RAW files, jpeg, or both?

Regarding Apple's lack of response, I should note that yesterday I fired off a question regarding Luminar to Skylum (formerly Macphun), and heard back the same day. I'm confused as to why photo processing capabilities would be so unimportant to Apple.

I had opened a bug report at Apple development which they closed because the error would have been solved since 10.13.4.
Clearly this is not solved yet, so I've reopened the bug report.

New iOS has crippled my editing process! 20 second lags with every adjustment!

1. Is Apple working on a bug fix?

2. Is reverting back to old iOS possible and helpful?

3. What other “easy” photo editing software is everyone using while this gets fixed? (Don’t day Lightroom)

Any help is appreciate, I’m dead in the water!

No - IOS version has nothing at all to do with this issue - IOS is only for mobile devices and has nothing to do with this thread which is about OS X High Sierra on a Mac and does not involve mobile devices or iOS in any way - and you can not really revert back on Mac OSs since the Photos library can not be opened with older software - you would have to also go back to the previous Photos Library which is generally not an acceptable or even available option

I just got a response from my bug report requesting that I upload a sysdiagnose and raw file from my camera. I was able to reproduce a one minute freeze right before generating the sysdiagnose and also sent the raw file that caused it. Previously, when I spoke to tech support on the phone, I was not asked to send any files. Fingers crossed that they are getting closer to a solution.

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!

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.

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.
