Very slow processing of raw pictures by Photos

I hear you

well you could try to do a repair if something is wrong

I just lost some photos but the scanner of faces had been stuck for some time

did you repair you aperture liberay before you converted it

I hope get on to this soon since this is a pain in the neck

The above article mentions the problem.

My Aperture library was good before I converted. It took me several tries to convert to Photos. I was still stuck at 644 converted out of 63k after several days, relaunches and reboots, so rebuilt the Photos library last night. That reset Photos Scanned to zero. 12 hours later at 171 photos scanned.

I should note that many people are identified and many photos are associated with their IDs. I assume this information came over from Aperture. I haven't checked, but my sense is that many photos with people still haven't been picked up. One other oddity with my collection in Aperture is that I have a person named 'unknown' that I used to not have to review faces that were of people I didn't need to track or of total strangers. Is this confusing Photos? Didn't seem to cause any problems for Aperture. Yet another subject.

Based on the experiences in this thread and Glenn's article, something is wrong with Photos; so I'll wait before doing anything drastic. We need send bug reports to Apple about the problem. They don't generally follow the discussion group, but maybe they do pay attention to Macworld articles.

It's not your Mac.

Photos since High Sierra has been useless to me.

Editing RAW photos in Aperture / Lightroom / Affinity Photo / Photoshop works perfectly. In Photos? It's impossible.

Several people are saying the same.

My current solution right now is going to be:

- Edit in Lightroom.

- Export JPEG files.

- Import to Photos.

Hopefully they fix the performance issues in the next update.

It is driving me completely nuts how slow Photos has got under High Sierra and how it is making the fans on my MacBook Pro and iMac spin up hard. It's so bad I've had to get an app called "App Police" to throttle the Photos processes. I do have a large library of 200,000+ images and many of them RAW, but it was never this bad before.

Bad news - I updated to 10.13.3 today and Photos is as slow as ever. Raw files take about a minute to be editable, even if they have been edited previously. The actual editing response seems slightly better but there is still a noticeable lag. Its unacceptable that the core image editing program that comes with the OS is slow, reported as such by many individuals, and yet the problem simply isn't being dealt with.

I am experiencing similar "latency" or "responsiveness" issues when editing RAW files. This is related to High Sierra (or the version of Apple Photos that came along with it) because I did not have this problem before.

The RAW files I am working on are about 45MB in size. All my images are stored in iCloud but that shouldn't be an issue because when you edit an image, you should be working on a locally stored version (which is on my main SSD in my case).

The problem I'm having is when making adjustments to RAW files. Whenever I apply a modification to the image using one of the adjustment sliders, the slider itself moves to the location that I chose, but it then takes several seconds before I see a change in the image and you start wondering if you moved the slider enough. You don't get a "processing..." indicator while it is actually working on the image, you are still allowed to move adjustment sliders. So, as a result, you change the slider, don't see anything and think "hmm, I didn't move it enough", move the slider a bit further, 15 seconds later, you see some jittery behaviour. Not workable at all. If I move too many sliders, macOS even stops responding.

I called technical support with this issue and the agent told me he found an existing case for this problem so I guess we can say this is a known issue. We went over my system specifications but nothing looked out of the ordinary. Hopefully they release a fix soon because I'm stuck.

Hi Menno, afraid not and it’s really frustrating that this sort of issue is not resolved quicker. I mean, it used to “just work” and to have it not work for months now, is just a slap in the face considering you are paying premium prices. I wonder if this is a general issue or related to specific iMac models. What model do you have?

The Mac is a mac-mini, mid 2011, with an i5-2.5Ghz; upgraded with an SSD and 16Gb RAM. Sure, not the fastest, but should be more than enough, especially the RAM for non-professional use. Mac OS 10.13.3; Photo App 3.0 (3251.12.190)

The camera is a Sony A7ii, I use the Sony compressed RAW files (ARW), they are 25Mb each, so smaller than the RAW of typical Nikon/Canon, or Sony uncompressed RAW. In general compressed RAW is more than good enough for me.

Whenever I edit RAW files in Apple Photos, if I touch something, I have no "response" for minutes literally. If I use Capture One 11, it it very responsive. But I use the Apple photos App normally, as it holds my library. Currently I do not import RAW anymore in Apple Photos.

My iMac is also upgraded with an SSD and has similar specs (only 8GB memory though). According to the call center agent I spoke with, my machine was still adequate in terms of performance and the behaviour we are experiencing was abnormal. I tried Affinity (Photoshop) as an alternative and this worked without any issue on my RAW files. If all my images were not in iPhotos already, I would have switched to an alternative by now. It does make you re-think if it is wise to put everything in iCloud though.

yes it is very scary

the stoped Iphoto and Aperture then they made this usless app

for self

I went back to Aperture with reff files and the the files are stored on one-drive

but we can only hope they get this fixed

but I don't think it will have with this beta maybe with the next one

I thought the slowness aspect was relevant.

Hi Jan,

Any update already on this issue? I face identical problems with Sony ARW files in Apple photos on High Sierra.
