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.

 

Thanks

Matt

Hi Matt,

 

We are sorry about the experience with Lightroom Classic on your Macbook Pro 16". Would you mind sharing the version of Lightroom Classic you are using along with your computer's macOS version?

 

You can try to optimize the preferences of Lightroom Classic using the steps mentioned here: https://helpx.adobe.com/lightroom-classic/kb/optimize-performance-lightroom.html

 

If you still experience issues, try creating a new catalog on the computer and import a few files to test the performance of the application and let us know if you observe some difference in the performance. 

 

Regards,

Nikunj

Yes, this has already been discussed many times. Fans running a lot on a MacBook Pro is a common problem, not just for Lightroom but for many other software. If you read any Apple forums, you will find plenty of discussion and suggestion for improving the situation.

 

The fact that this doesn't happen with Photoshop is irrelevant.

 

In Lightroom, if you have high megapixel images, and are doing lots of local adjustments (brushing or spot healing) on an image, this could cause the slowdown you mention and the heat build-up, which causes the fans to run. But as I said, Lightroom is not the only software that causes this heat buildup and fans running on a Macbook Pro.
