Imac 5K issues

  • Updated 1 year ago
Hi,
I have a new 27" iMac w/
3.2 GHz Intel Core i5 
32 G of RAM
with an AMD Radeon R9 M390 2048 MB card
From day one I noticed performance issues, Apple swapped it out and still having problems. Since then Apple and Adobe have admitted to me (finally) that there are 5K issues (as most of you probably already knew). However this problem has gotten so bad that at times my machine is BARELY usable and now crashing at least once a day. I was on the phone w Adobe support and they played w some settings, tried smaller catalogues and separate user accounts on my computer. All to no avail. The problem is pretty consistent and although there was temporary relief with some of these issues, as soon as I started editing pretty quickly things returned to a crawl. Its not even usable it gets so bad at times. Part of the problem is that Im not very familiar with common computer nomenclature and pretty quickly everyone is talking Greek to me. Im a new start up company and Im imploding rapidly over here and nothing short of completely overwhelmed. Please help me if you have any ideas. Thank you

Let's start with some important details CG:

What specifically is slow? For example, is opening Lightroom slow? Is moving from image to image slow? In which module? Where are you having the biggest problems?

And you mentioned it's crashing? What exactly happens, and what are you doing just before it crashes?

Where's the catalog stored? And what about the images - where are they stored? Internal SSD? External USB? NAS? What camera are they from?

When its bogged down, everything. Basic, HSL and Detail are the worst with Spot removal (especially as they accumulate), Brush and any "color" adjustments at the top of the list. Sliderbars universally become completely useless for incremental adjustments. Even adjusting slowly with the uo/down keys takes seconds to refresh. Overall.. the more I edit in one photo the worse it gets. Once the photo is "bogged down" everything becomes almost useless with the amount of lag. 

LR shuts down unexpectedly (crashes), pop up window comes up with an option to send to Apple (unfortunately I haven't catalogued these) which I usually do. Only pattern (?) I can see is unplugging of my iPhone a few times but seems random thus far. But is now a daily occurrence and Im losing work. 

Catalogue is one (large) and stored onboard on a 1T Fusion Camera: Canon 5D MKlll

Yes... I'd like more specifics about exactly what sort of problem you are seeing.  I manage a lab with over 30 iMacs having exactly the configuration you describe.  They're used primarily for running Adobe apps.  Lightroom is run heavily on all of these machines.  I've not seen such a problem but if there's some real 5K related issue out there I'd like to know about it.  Give me some precise steps and I'd be glad to try and replicate whatever you're seeing.

Our systems use internal flash drives for sys and programs.  All data is on USB3 External solid state drives.  From what you write the first thing I'd look at is main drive directory health.  I use DiskWarrior for such things.  Those Fusion drives are marginally better than a pure spinning drive but they're not as good as fast SSDs for Lightroom's database driven work.  Consider moving your catalog, previews (and images too if you have room) to a very fast SSD USB3 external.  Those aren't horribly expensive any more.  Catalog size shouldn't matter.  My personal catalog is at almost 400k images now and performs just like smaller catalogs until you try to do a backup or optimize task.

Hi CG. I have a similar machine (faster processor, older graphics card, same RAM) and I don't see the symptoms you describe. While, of course, I'd like it to be faster, it seems pretty much what I'd expect. And it isn't crashing.

My recommendations
1) Save your crash logs & messages. Someone here might be able to interpret them (tho not me, probably).

2) Perhaps you are just doing things that Lightroom doesn't handle well. There have been plenty of reports of spotting being very slow if you do a lot of it in Lightroom. If it were me, I'd do the spotting in Photoshop (it's easy, just add a layer). I prefer spotting in Photoshop anyway—it's much easier to control. The only question is: Do want to make all your other adjustments in Lightroom, then convert to TIFF and spot in Photoshop—or do you want to spot first, save as a TIFF, and then, if you find it easier, make the other edits in Lightroom. Sometimes Lightroom's ability to undo everything just gets in the way.

3) Or, if you don't want to learn even the basics of Photoshop, make some edits, then export the file as a 16-bit TIFF, and then make more edits on that file. You lose some flexibility that way, but if it avoids crashing...

4) Do what Bob Smith recommends too.

Ok... just got off the phone w/ store Mgr and they agreed to swap the machine again. This will be the new updated version. They concurred that performance complaints are common but still usable at least. Faster processor, bigger graphics card.
3.8GHz Processor
2TB Storage (fusion)
3.8GHz quad-core 7th-generation Intel Core i5 processor
32GB 2400MHz memmory
2TB Fusion Drive1
Radeon Pro 580 with 8GB video memory
Now I'm wondering if I should restore from my backup or not. Maybe something corrupted in the catalog? thoughts?

If your catalog passes consistency checks, I wouldn't worry about it. (Choose Lightroom : Catalog Settings : Backup Catalog : When Lightroom next exits).

Of course, if you are still worried, then write out all the metadata and create a new catalog. You will lose a lot of information (pick/reject, collections, etc), but you will at least know that there is no corruption.

But I'd just go with your original catalog after you check it.

PS--Restoring from a backup is only helpful if you know that your current catalog is corrupt and your previous one is not corrupt — and I don't think you can say that.

Before returning it to Apple I backed up Lightroom, then the whole computer. New one arriving within the hr. So if this is true, I should be fine . Correct?

In case you haven't already, also skim through my free Performance eBook, just in case there's some extra tips you're not already aware of. https://www.lightroomqueen.com/performance

Update with new machine:
So far this new computer (from a restored backup) runs completely different. It only has 8G of RAM right now (the new RAM is not in stock yet at the store level yet, 32G to arrive Friday) and its much better already. Ive edited a few photos and the speed is much faster. After reading some of Victoria Bamptons book, its becoming apparent to me that Im also using the "wrong tool for the job", as also suggested by Ala Harperl. LR being a "Parametric editor" was certainly contributing to what I described as a "cumulative issue". Doing product photos, I can sometimes get "lost in the lines" with things like spot removal on a close up of a black T-shirt (the best tool there would have been a better lint roller ;). Im going to continue on this book as its been very insightful so far. I want to thank you Victoria for compiling and providing this resource. Thanks to the rest of you as well for taking your time with me. I will update this post soon once I can lean on this machine a bit more. Saving up for an external SSD is the next hardware priority. Thanks again everyone.

That's wonderful news CG, thanks for the update.
