Lightroom Classic is BROKEN under M1 Macs with Rosetta. BEWARE!

[h4ck1nt0$h3r]

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

I have uploaded this video showing the nonsense. When culling a folder with around 1800 photos it wrote 7GB of data to the SSD in 30 seconds.

There's no way these SSD's will survive this.
Adobe need to do something ASAP!
Until it's fixed I will need to go back to my Intel MBP 2017.

I'v already posted this into adobe forums, let's see what they reply.

Not seeing anything like that here.

(the overall data read/written is related to moving large folders and doing full backups, not LR related)

how is that an issue?

Do you have GPPU acelleration enabled in LR? I found that disabling it the writing to disk is much lower... but not near the normal.

how is that an issue?

Why would it be normal? Why LR is writing 100gb of data in 15 mins? It's 2x the entire folder size.

Yes - LR Preferences->Performance->UseGraphicsProcessor is set to Auto and it shows "Apple M1".

Do you have an 8GB or 16GB?
In fact watching the activity monitor the writing is attributed to kernel, and that's Swap.
I'v been working this morning for around 3 hours and it wrote 200gb already.

16GB RAM. Adobe isn't exactly a paragon of efficiency in resource utilization.

Is it creating previews or using swap?

Seems to be Swap after all... adobe need's to fix their code.

I might have to let the MBKP aside for personal use and get a Mac Mini with 16Gb... Or I will wait until the M1X/2 come mid next year.
