1TB of cloud storage is included with a subscription. The professional photo editing software is free to download, but requires a $9.99 monthly subscription via Apple's in-app purchase system after a one-week trial. Adobe announced the release of Photoshop Beta for Apple silicon last month and says it is working on a native version of Lightroom Classic for Apple silicon that will be released next year.Įarlier versions of the photo-editing app worked on M1 Macs, but had to be run via Apple's Rosetta software, which translates made-for-Intel x86 code to allow it to work on machines powered by Apple silicon. It would still probably give us some performance improvement without crazy disk writes, at least on 16GB models.Adobe today updated Lightroom CC to version 4.1 in the Mac App Store to bring native support for Apple's new M1 Macs.Īdobe has been working to bring its Creative Cloud apps to Apple's new Macs. Even best SSDs will die in 2 years with that heavy writes.įor now, I can live with basic acceleration and keep fingers crossed that it'll still solve the problem for me even with 4k display connected.īut it looks like something that Adobe SHOULD SOLVE.Īt the very least there should be an option to set memory value to let's say, 2-4GB. It's actually amazing how good it functions on M1 mac, no slowdowns but it's still really dangerous with regular usage. When full acceleration is on Lightroom claims 10.5GB out of 16GB of unified RAM and writes some that to it like crazy. performance oh well, if that I'd have to live with, I'd be pissed because this is not what I've expected from this machine.Īll in all, I think the reason for this madness with full GPU acceleration on is here: Lightroom reserved around 12GB Virtual Memory performance still fine (as in very decent upgrade from 2016MBP13) OK behaviour, kernel_task is not writing to swap like crazy. Lightroom reserved around 16GB Virtual Memory Lightroom reserves around 23-25GB Virtual Memory at least The situation is following with different GPU acceleration settings: No external display (I don't have access to mine at the moment and I'm afraid it's going to make an impact.) What helps is playing with GPU acceleration settings. Resetting preferences, rebuilding catalogue and all those tweaks did not help. Even the best SSDs (I mean, assuming real-world durability being as high as 1petabyte write lifetime) cannot survive this in the long run! Swapping is all fine on modern machines but writing hundreds of gigabytes of data in a few hour session in Lightroom Classic is definitely not. Feels almost like using Lightroom Classic makes kernel constantly drop GPU's memory content on disk (which would explain why some people report that disabling GPU acceleration helps a bit.). It seems like some Lightroom/Rosetta/Swapping bug. I have no idea what's the reason but discussions on Mac forums indicate that it's widespread. It doesn't happen when scrolling images in "Library" and basically doesn't persist when I do nothing or close Lightroom Classic and work with other applications. And this is not some weird "cache writes" that do not affect the SSD like some people on Mac forums tries to "explain", SSD health tools confirm those writes. In 15 minutes of scrolling through images and applying some presets at Random and I'm at whopping 20GB written to disk by kernel_task. What's most important this is reflected in writes to disk done by "kernel_task". Almost instantly it took13-14GB of memory (I'd not care honestly) but inspecting the process showed that Virtual Memory grows steadily as you operate in "Develop" tab. To make a bit more "scientific" test I've restarted the machine and and launched no application except the Lightroom Classic. Today in the morning I've been mostly running Slack + Safari today and then opened Lightroom Classic twice just for testing and I've had 450GB of writes! M1 MBP has quite intense swappiness (indicated by kernel_task writes) but running Lightroom Classic results with absolutely CRAZY DISK WRITES by kernel_task. Lightroom Classic runs blazingly fast! But there's a very concerning issue. I have MBP13 with M1 Apple Sillicon processor. Usually, I'd consider this kind of digging into stats when all works well as a bit dumb but actually.
