Hi all,

my apologies if the subject has been already discussed but this is something that drives me crazy especially after having paid a new macbookpro 6 thousand dollars.

My mbp has the following features:

  • 64 GB of RAM
  • 2.4 GHz 9-core ninth genration Intel Core i9 with Turbo Boost up to 5.0 GHz
  • AMD Radeon Pro 5500M with 8GB of GDDR6 memory
  • 1TB of SSD storage

I use photoshop CC, final cut pro in a professional use and I have no issues at all. As soon as I use Lightroom Classic and I start using some brushes or filters or few sliders the fan of the macbook pro starts and it sounds like an airplane ready for take off.

Obviously the mac gets slow straight away and to work on a RAW file of 30 something mb becomes very hard.

I wonder if it is my computer or a problem related to Lightroom Classic.

I'd say it's a problem related to Lightroom as, as I mentioned above, I do other milion things with my mac and I have never heard the fan working full revs.

My mac is connected to a Benq SW270c 2k external monitor through USB-C port.

My lightroom catalogue is on an external SSD samsung

The cache has been increased up to 200GB

The original photos are on an SSD

The catalogue includes arouns 70,000 pictures.

Don't know if you need any other info, but I really need your help.



Lr uses more processor resources than ps or final cut.  My i9 imac also turns on the fans.  However, i dont experience a big slowdown using lr with 125mb files.
