Lightroom Classic & Desktop: disk read/write to SSD M1 Macs with Rosetta

Hi.
I'v just installed LR Classic on my M1 Macbook pro with 8G/256GB, and LR is broken.
It works blazing fast, but as fast it's destroying my SSD.
It wrote around 100GB of data in 15 minutes.

I have uploaded this video showing the issue. When culling a folder with around 1800 photos it wrote 7GB of data to the SSD in 30 seconds. (standard previews already created)

There's no way these SSD's will survive this. 
Adobe need to do something ASAP!

Specs:
Macbook Pro M1 8GB/256GB
LR Classic V10.1

Adobe does indeed officially support Lightroom Classic on the M1:

https://helpx.adobe.com/download-install/kb/apple-silicon-m1-chip.html 

"DOES ADOBE SUPPORT APPS RUNNING USING ROSETTA 2?

We provide support for the apps listed above."

The list of apps includes Lightroom Classic.  The "known issues" link leads to this:

https://helpx.adobe.com/lightroom-classic/kb/macos-big-sur-compatibility.html#AppleSiliconcompatibility 

"There are no known issues specific to running Lightoom Classic 10.x under Rosetta 2 emulation mode on Apple devices with M1 processors running macOS BigSur (version 11)."

Obviously, there are known issues, but the overall fact remains that Adobe does support running LR Classic on the M1.

Go reread the link, doesn't say anything about support.  "that run" does not mean supported. They have not fixed any Lightroom bugs for the M1 with any of the latest releases.

All this said, it is a poor show from Adobe, in my respectful opinion, that their flagship catalogue program - Lightroom Classic - does not run natively on M1 a full six months after the release of that platform. I dare say that Adobe knew about M1 as an Apple developer long before the public were too making it even worse.  Kudos to them for getting PS onto M1.  Every other SW I use now has native support except for LC.

When is the next update, going by previous years? I feel this needs to be addressed soon and also add native support… disappointed so far…

There will not be an update to the Intel version for the M1. Why would Adobe waste their time on that when they are developing a native mode version?

That was what I meant, release the M1 version and fix the memory leak . Is it a 4 month quarterly update cycle? Last was mid March? So next is no until mid July?

LR generally releases about every two months. Since LR 10.2 was released on 3/16, we might expect 10.3 mid-May. But there was a patch release 10.1.1 in January to fix a severe bug, so it wouldn't surprise me if 10.3 was a little later.  While Adobe has stated publicly there would be a native M1 version "in 2021", they rarely get more specific (and stating "in 2021" is more specific than they usually get).

Thanks! That’s at least sooner than I feared 👍🏽

In fact it's overdue... assuming they have the M1 in hands for at least an year now... it's a shame a big company like adobe taking so long to release it... PS and LR  should have been released in november with the M1 support since the beginning.

For all those following, this Ram leak has plagued the PC crowd for at least 4 years now. As soon as it has eaten all your GPU RAM, the entire program slows to a crawl. It also eats CPU RAM, while in the Library Module, but since we tend to have much more CPU ram, it is not usually noticed. I have had 2 fully different machines; one Intel, and now a brand new Treadripper 24core beast of a consumer super computer. BOTH have suffered from this debilitating RAM issue and it has taken Adobe to this year to actually acknowledge that there was even a problem. They have spent the last 4 years telling the PC crowd that there was no issue and we should just reinstall LRCC, or reset our preferences, or switch to a new catalog... So, if you are waiting for a fix, don't hold your breath... They already have your money and there are very few alternative programs out there. AKA they don't care.

So... good news! Testing the new Adobe LR Classic native for Apple Silicon has solved part of the problem.

The vram management bug seems to have been solved when graphic acceleration is disabled. When it's enabled, it's the same mess...

I managed to develop and export 280 raw files and the kernel writes were around 20gb. It's probably related to other programs I had open, but in normal use I could not find it excessive.

It would be nice to those who have the 16gb option to try with acceleration ON... In my case now it's probably a limitation of low ram... the SO itself and background programs are using 60% of the ram leaving LR less than it should.

@CarlosFerrari Turning the GPU acceleration off has been a long standing "fix". But doesn't solve anything other than the RAM leak in the GPU. It slows the processes down to nearly the same speed as when the RAM has fully leaked. Adobe needs to fix the problem. There really isn't a work around for it. Adobe needs to suck it up and fix the issue. (Again, it's been 5 years for us PC users... they've had the time...)

Exactly Carlos, I'm noticing the exact same things on my 16GB M1 Mini.  

After upgrading LR the disk writes seemed to get a lot lower, so I tried enabling the graphic acceleration again to also test that. 

Disk writes were crazy high again after doing that so I turned it off again!

I had around 200 GB kernel writing after maybe 300 images gone through with 150 edited and exported. Seems it’s 11-12 times higher than what the actual files are…

But I thought an M1 version was supposed to fix all of the problems us whiney folks have been complaining about 😉

I specifically registered on this forum to confirm the issue under discussion. Fortunately, it turned out that I was not the only one.
I have a new MacBook Pro M1, 8GB RAM, 1TB SSD. System - macOS 11.4. The native version of Lightroom Classic for Apple M1 (10.3) still writes a lot on SSD. As a result of simple processing and export of 30-40 photos in RAW format from Canon 5D Mark IV, about 800 Gb (!) are recorded on the internal SSD of MacBook. It turns out that in half an hour the entire disc is almost completely overwritten. It’s just unimaginable, but it’s a fact. It's worth noting that the Lightroom catalog and photos themselves were housed on an external SSD!
Disabling graphic acceleration helped a little, the numbers decreased by about one and a half times, but it's still a lot.

I managed to slow the kernel writes by quitting applications and monitoring RAM with iStats.

When using LR I'm making sure it's the only program running. I quit Adobe CC / Dropbox etc... sometimes I leave chrome with Spotify open as it uses less ram than the native app (lol).

That's life with only 8GB ram :(

800GB with processing 30-40 photos ?? I have about 80-120 GB doing the same…

@viggo_n_ss before exporting quit LR.. and make sure you have Graphs disabled.

I'v exported 200+ here with 20GB writes.. (and some of this are the photos itself)

@viggo_n_ss Yes exactly. Checked it several times before writing a post. Sometimes it turns out less, but in any case more than 500 gigabytes (especially if graphics acceleration is enabled).
My previous MacBook Pro 13 2015 also had 8GB of RAM, was noticeably slower, but didn't write as much data to the SSD. Maximum - 150 gigabytes after many hours of session with hundreds of photos.

Lightroom runs OK with 16GB of RAM and well on 32 or more. You bought a lightweight machine and are suffering the consequences.

 

The M1 is not magic, applications need just as much RAM as they did on Intel machines. Perhaps even more because RISC processors (the M1) require many more instructions for the same function as CISC processors (Intel).

 

In the interim, shut down and restart Lightroom frequently, the interim being when you buy a proper machine for Lightroom.

@bill_3305731 Obviously you don't have a firm grasp of what we're talking about. I for one have a Threadripper 24 core 48 thread with 128Gbs of RAM and a GPU with 16Gbs... (it's pretty much a consumer grade super computer) and I'm having the same trouble everyone else is. Needless to say, you are ALSO having the same trouble as we are. You just don't have the tools or the whit to realize it yourself. Please refrain from downplaying our troubles when you have little knowledge on the subject. Simply put: I've known LR is broken and has been for several years now. Ever since they introduced the GPU acceleration. Now it just happens that others have finally figured it out as well because Apple has given them the tools to see it. Now... instead of crapping on others, you think you can help us get Adobe to actually FIX the problem? Ya know, like be part of the solution instead of the problem?
