High Sierra photo editing slow

After using Photos and watching network traffic in the last few days - this sure seems like an iCloud communication/sync issue with the photos library in iCloud. When trying to work on photos that synced that were shot on my phone, if I try to look through photos quickly or edit, Photos will lock up and even crash. If I wait for 30 minutes( letting the syncing settle down) and try again I have much better success. Something is wrong with the syncing mechanism and it locks up everything - I sure hope Apple is paying attention to crash reports and fixes this soon...

So, following the logic that this is some sort of syncing/communication error, wouldn't turning off wifi - thus killing all communication & syncing with the cloud - speed things up and allow editing to work as it did before?

I'm having the very same issues. It is taking too long to do simple edits. I almost wish I wouldn't have upgraded to High Sierra because of this. When you work with large numbers of photos, and it takes so long just to do a simple retouch it's frustrating. And then a few seconds later is looks different again.

Glad it's not just me. I've timed myself editing a photo. A quick crop and knocking down the highlights, a 10 second job before. Now it's taking 1 minute 36 - in which time the computer freezes entirely so there is nothing else I can do.

I'm having the same problem on my 2014 Mac mini since upgrading to "High Sierra." I used to adjust the light slider and watch the photo change, but now I move it and wait for seconds before any change takes place. Really poor performance.

In Sierra Photos I had an issue with cropping edits not taking. The picture would pop back to its original uncropped state unexpectedly. This issue still happens occasionally, but now with the entire editing process ground to a halt, it seems like a minor issue comparatively.

My Macbook Pro has exactly same issu. I found when ever if I unpluged the power adapter, and the system using the intergrated graphics, the photos app works just fine; but if I plugged the power adapter back in, the NVIDIA GeForce GT 650M discrete graphics will kick in, and everything in photos app became very slow.

I have the same issue.

I have recently upgraded my MacBook Air (13-inch, Mid 2011) with 8GB RAM and over 300GB free space on SSD to High Sierra. i started to load some images on Finder and found that it was taking really long so I decided to use Photo app, but had the same problem.

I went on to use Preview and run into the same problem. I even noticed that some of the images load incorrectly, parts of the image are distorted as if they were corrupt. I leave it for about a minute or two and the image corrects itself. I am loading Raw files of about 30MB per image which is quite heavy, so I converted the images to 5mb JPGs and still have the same problem.

It takes about 20 seconds to load each JPG image and editing is near impossible. I have had to stop editing pictures and wait till I am back home to use my iMac, which has El Capitan. Will not be upgrading any time soon.

Please Apple any light on the issue would be great. Also don't make it so hard to downgrade after updating OS, just really infuriating. I cant do anything at the moment, but wait and complain in forums about this.

That's very interesting! I've been trying to see if this works for me - connected to power and then unconnected - and it seems to be the same for me.

Unconnected from power, Photos.app speeds up. Not as fast as Sierra, but a noticeable improvement from being connected to power.

i had the same problem after update my macBook Pro (Retina, 15-inch, Late 2013).i cant work and fix my photos..evertything is so slow after update macos high sierra....any solution about this problem?????

Larry, I do confirm, that the CPU increases on my MacMini on the Photo app over 300% as well. It happens in editing a picture, especially in retouching the picture. After touching a picture 5-10 or more times (cause you want to remove some stuff like personal strictly confidential data), the CPU goes up to 300% and higher. You must close Photo going back to normal CPS state. That behaviour was not so strong/bad on the same box with 10.12.6. The upgrade from 10.12.6 to 10.13.1 changed it all. It becomes a very bad time consuming waiting time, especially if you run VmWare in parallel. The complete system feels like a frozen time. That has not happened before. Stopping VmWare or other processes do not stop that behaviour. 😟 😮

Yes, retouching seems to be the main problem. I just confirmed your results on my 2014 Mac mini, and retouching is what seems to drive the memory use up very high. I crashed Photos three times pretty quickly by just retouching one photo. Memory utilization for Photos was over 300%.

Also the retouching tool doesn't work as well as before. When masking something out it leaves a distinct shadow outline of what was there. Or if attempting to duplicate another part of the photo, it's only a partially opaque.

This is very disappointing and bad timing by Apple, as I am attempting to clean up lots of old slides to make photo books for Christmas presents. This effort is now not possible until they fix these issues.

Yes, I have High Sierra on my 2011 iMac, and retouching in Photos is suddenly pretty impossible, even with all other programs closed. Each retouching action takes about a full minute to complete, and even then, I often have to repeat the same action several times for it to work.

Issue on Photo, an issue on root, finally on shares. What else next? We do not talk about rocket scientes solutions, that is basic stuff. It looks like the Phönix project about DevOps. Where is Brent to fix it? Personally, I am very disappointed.

Finally I have to restore with TimeMachine and CCC back to 10.12.6 on my severs and workstations to run operations. Always good to have a backup and a tested routine for restore.

Effort: 2 man days of engineering, 4 people cannot work = 10 man days in total! Who will pay opertational loss? Dear Mr. Tim Cook, that is a Real Desaster. Where is the accuracy and love to deploy and to test software?

MEH - I'd help off upgrading from El Capitan because every time i upgraded, my mac book pro had a problem. SO, upgraded to Mac Os High Sierra yesterday and now have s l o w photo editing - it whirs and eventually carries out c

the edit:(((

Is there a fix yet?? Wish I hadn't bothered

Apple get your finger out

Is anyone at Apple actually doing anything about this? It is positively painful and there are times when just opening a photo freezes everything for 90 seconds.

Alternatively, can I uninstall High Sierra without losing everything I've loaded up in the last couple of weeks? I'd much rather go back to an old, working system, than having to struggle through with this rubbish.
