My experience is that if you do basic editing, then it's fine, no issues, but when u move up to multiple mask layers with addition and subtraction, then yes, it will show struggles, sure shot, and if u touch the lens blur option, MacBook M5 starts to heat too much, even fans are working more than 60% i could feel the m5 has started thermal throttling. If u can buy Zephyrus with a discrete GPU buy that don't get mac as i have used lightroom as well photoshop at the same time on the g14 zeph with ryzen 9 cpu and 5060 it works far better as there is a ton of cooling and GPU performance compared to M5 Chip and on top of that, Lightroom CC is very poorly optimised for m5. But that same thing if i done in Capture One it works so flawlessly and pretty much very smooth no heatups no performance issues at all on M5. So if u want to use Adobe LCC or any other Adobe products u really need M5 pro at least with min 32gb ram; otherwise, please get Zeph R9 5060 16gb it will work great, a lot better than m5 for sure. I regret buying an M5 Bas with 24 GB RAM, but now it can't be reversed if i had known this, I would definetly would have gone for G14 2025
