High Sierra Photos Editing Issue

My Photos is at present working as it should!!! Here is the pain I went through to get this working and the some pain I continue to have:

1. I backed up my drive to an external drive using Superduper! - This makes a bootable copy of my system in case something went wrong( I also back up to Time Machine and Backblaze but I wanted to be safe)
2. I did a clean install of 10.13.3 High Sierra - which included the following steps
   1. Created a bootable installation USB drive for 10.13.3 High Sierra
   2. Booted system to the above USB drive
   3. Erased my hard drive using disk utilities on bootable USB
   4. Installed High Seirra
   5. During install, 1 migrated all users, data and settings EXCEPT applications from backup I made in step 1. This means I will have to install all 3rd party apps manually.
3. Once Step 2 completed in total(about 7 hours later) I tried using Photos and it worked great! Yay!
4. The next thing I did was install back my missing apps one by one. After each app install I would restart and check Photos. The apps that installed and DID NOT affect Photos performance are as follows:
   1. Office 2016
   2. Pages
   3. Numbers
   4. Keynote
   5. Backblaze
5. Dropbox however broke Photos. I installed Dropbox for Business, linked it back to my Dropbox folder, rebooted, logged back in and waited for a bit. Then I checked Photos and I was back to the lock up behavior described in my previous post 😟 Once I quit Dropbox and uninstalled it (threw it away out of the Applications folder) and restarted, Photos started working as it should.

I will keep checking Photos over the next week and post if it starts acting up again I still have to install Steam and Parallels and I will post if those break Photos.

Hope that helps - Will send Apple feedback as well.

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.

IMPORTANT UPDATE :

I called Apple this week-end regarding this issue. On the French side, both technicians were clueless about the software problem and thought my computer was at fault.

I then called on the English side, where I was told indeed there is a software problem and that the engineers were working on it to get it fixed ASAP.

The stunning part is that none of them are aloud to read what is going on in Apple discussion forums.

So, no amount of questioning or whining here helps out the core issue.

I was told to tell all the people here to call & report directly to Apple the issue and create a case number.

If not, they will never see what is going on here and that is why it takes so long for any 'universal' issue to get fixed.

Also, depending on the customer service person you land on, they might not know how to access proper data regarding those wide-spread issues and one is told - as I was told twice on the French side - that there were no problems like that ever reported.

Needless to say, I was stunned.

The following has appeared to help (slow processing and crashes):

1. Turn off Spotlight by disabling the indexing of the hard drive

2. Quit mail

While faster and no crashes, it is still not useable for serious editing

or

1. Add new, non-administrator, user (there will be considerably few processes running), process raw photos here and save where accessible to other users.

While still slow, it is useable and did not crash.

None of Apples suggestions have worked

Photos works fine for me with any jpeg file: Sony RX100, Olympus E-M5, iPhone or iPad. Sony .arw raw files, which are 20 megapixels and larger than the olympus 16 megapixel .orf files, are just a bit sluggish compared to editing jpegs. Olympus files will slow my 2011 iMac to a crawl even though they are smaller than the Sony raw files. I tried converting both the .orf and .arw files to Adobe .dng (digital negative raw) before importing into Photos to see what would happen. Each raw file becomes a bit larger in .dng format. I was hoping this would be a work-around for the Olympus. Turns out the .dng files generated from both the Sony and the Olympus are all super slow to edit. Also found that older raw files from my Olympus E-30 from years ago are no problem to edit. I am convinced that Photos 3, introduced with High Sierra, is the problem. I know there are system resources involved, but I don't think there will be a solution until they revise the actual Photos app. Previous versions of Photos were all super fast editing my raw files. I missed features from Aperture, but speed was actually much better. My only work-around for now is to shoot jpeg plus raw with the Olympus and just edit the jpegs until this issue is resolved.

Hi there yes it is slow

But i found out is files form my D90 and d200 Are slow it is lighting fast with my D3 and d4 files and they are much bigger

The problem i Think is Camera releated (Apples raw decoder)

I did some Quick. Tests but d90 raw converted to dng helped alot on my case

10.13.1 is not released and Beta software can not be discussed in public forums like this

It may help to keep your Mac powered and awake and let all of the new background processing and scanning complete - as it finishes things probably will get better

Well I think I fixed mine issues

last night I did a clean installation using a USB drive

and now photos seems to working much better

the first raw taks a few seconds to load in edit mode after that I can flick thru them with no lag

OK I’ve started to push 10.13.4 a bit harder than light tasks in photos 3 and so far so good! No crashes. NB I’m using jpegs only. Doing multiple retouches in editing is about the same as Sierra, with a bit of a slowdown if you do many retouched quickly... not bad.

I’m cautiously hoping it’s now fixed for the RAWless anyway...

I didn't ever use the retouch tool until well after I had the problem. In fact, I tried it because people in this discussion said it was causing slowness for them and I found that it does slow Photos down for me when editing raw files. My DxO OpticsPro extension behaves the same way and I am not able to use it on raw files for long before a freeze. So, I don't think this is just an issue with the retouch tool. When I was transferred to an Apple tech who specialized in Photos, she said that even her menu clock would stop while her computer froze for minutes at a time trying to edit raw files in Photos. I didn't ask what tools she used, but she did take extensive information including the specific model camera and revision that produced the raw files. She did say that her raw files were not Olympus .orf, but it sounded very much like what is happening to me and what others describe in the discussions here. I get the behavior on a 2011 iMac and my wife has the same problem on her 2013 MacBook Air. These raw files never caused a problem in Photos before the upgrade to High Sierra. It would surprise me if "very few" people have the problem.

I am able to import RAW but editing remains very problematic. Slow, laggard, computer freezes. I, too, uploaded an example for Apple's engineers.

To try to further diagnose the issue, Apple customer support arranged for me to take my backup drive to an Apple store and test out my "Photos" library on a new machine. The problem with RAW editing remained! (So, the problem would seem to be in the "Photos" software, rather than in any hardware).

Supposedly, editing of jpegs is now fixed, and my computer seems to be fine with those files.

Apple is obviously trying to hone in on a solution, but WHEN will it come about remains the question.

Yes, still issues with Photos v3in High Sierra. It quits out quite often when going into edit mode, particularly when opening a photo that already has many retouches.

The exercise I’m going through at the moment is uploading all my photos - 150gb - from my Sierra iMac to iCloud (very slow process) and once down I’ll turn on iCloud on my High Sierra iMac and download my whole library into a new blank photo library.

AppleCare are following through supporting me in this exercise and the tech guy is writing s full report to the Apple engineers... stay tuned!

In other threads some people report that 10.13.3 has helped or solved the issue, others report that it has not change on their system - the way to find out is to update to the current software

OK, it MUST be a bug.

I've taken my last Sierra backup of my Photos system library and copied it onto my old 2010 iMac running 10.12 - Sierra with Photos v2.

WORKS perfectly! I've tried everything to make it crash and absolutely no problems! Photos that I thought were damaged (many with hundreds of retouches) are fine. Phew!

So something seriously went wrong during the upgrade to High Sierra with the Photos migration.

Reverting to Sierra for Photos is the only thing I can get working but don’t forget I’m an amateur just trying to work out my system. I’m certain Apple needs to fix something in high Sierra but in the mean time I’m working with Photos on my old iMac but everything else in recent iMac 2014. I’m waiting for AppleCare to ring back but if no news of impending bug release for High Sierra I’m thinking of partitioning my 2014 iMac with High Sierra and Sierra to simplify access to Photos.
