High Sierra photo editing slow

I didn't have dropbox sync with iMac Photos, but I have reinstalled operating system, recovery for photos and Photos still crashed after 50 seconds

Yes, keep up the chatter. Some people say there are improvements but I can't see any. My AppleCare tech doesn't reply to me... 😟

Hi,

I'm also still seeing this issue.

If there was a clear migration path to Adobe LR, I would have already left osx photos.

Does reverting back to old iOS fix the lag problems?

I have the same problem! So annoying... apple fix your problems!

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?

Cynsha can you afford iCloud Photo Library?

I have 150gb and it took weeks to upload from the Sierra but was well worth it. Photos works fine in the High Sierra iMac as long as you don’t edit. You can still organise and title photos etc and with iCloud any changes you make on either Mac are reflected in both macs.

I agree 100%.

Were you able to download and install iPhotos even with High Sierra? If so, and it works, what version of iPhotos? Does it conflict at all with Photos? I might try that myself. I'm getting really frustrated having to move raw photos back and forth between my iMac (on High Sierra) and my MacBook (still on Sierra).

Since installing High Sierra, my Photos hasn’t been the same. I use Photos on my iMac in conjunction with iCloud as a mechanism to backup my Nikon RAW pics and share them with all of my other IOS devices, MacBooks & AppleTVs. While I am able to “import” into Photos - the background processes, uploading to iCloud, stall after an hour or so of initial sluggish progress. Speaking directly to Apple Support, we have launched in safe mode and toggle the iCloud setting in Photos off and on. The process restarts and shows some life, but still stalls and I stare at the CPU memory resources top out, and network traffic at a minimum. I am keeping Apple Support on the hook, hoping to find an expert on this app and supporting services. A couple of thousand down and 50,000plus to go... argh. Life before High Sierra - fond memories.

I'm experiencing this problem on the brand new Imac my employer just purchased for me to use at work. As my main job of editing many jpeg photos throughout the day, I am reduced to dread and frustration with using this newest version of Photos on High Sierra. The old iPhoto program I was using from 2009 was actually working better! The main tool I use and need is the retouching tool. After 5-10 retouches on the same picture it starts to become exceeding slow, where I have to wait 10 seconds or more to see the result, and then it will only then actually do the retouching half the time. Then, all the other editing features become equally as slow, and it continues to lag, practically unusably, until I can save and close, or force close, and then reopen. As frustrating as this this is, it's helpful to know it's a widespread issue. Does/Will it help to contact customer care? This is beyond frustrating and totally unacceptable for a new machine!!

Interesting suggestion, but I don't think it is GPU related. My 2011 iMac has an AMD Radeon HD 6770M GPU and my 2013 MacBook Air uses Intel HD Graphics 4000. Both computers have problems editing the same raw files, even with 10.13.4. Also, I can see massive processor use when trying to edit raw files. This does not seem to happen at the point when the image would be displayed, but while a tool or the image itself is loading. It is not clear from several discussions if the latest system update to 10.13.4 fixes the problem with folks who have problems with jpegs. It certainly does not fix my problems with raw files.

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.

It looks like my problem completely went away after applying the update of 10.13.3 :-)
