Heating issue in MacBook Pro using Lightroom classic

I have an heating issue in my macbook pro which has i9 processor and 32 gb of ram and 2 tb of storage. It heats up in using of 30 min. Its gpu if full acccelerated too. Apple care center are telling that you are using a high end sofware so it is heating.

Sadly, I think this is expected and not surprising on an Intel Mac. Similar to recent generations of Intel-based Windows laptops, the last generations of Intel Mac laptops were plagued by the poor thermal efficiency and relatively high power consumption of the Intel CPU. This was a major reason Apple abandoned Intel and made their own ARM-based Apple Silicon processor. The Intel processors are fast, but high performance consumes maximum energy and generates maximum heat. In a thin laptop case the cooling system can’t keep up, so after an extended period of high performance processing, the only way to cool down is to slow down: It has an i9 processor, but cannot run at full i9 speed as long as it’s too hot.

This led to more bad outcomes: Poor battery runtime, poor battery lifetime (because high heat makes batteries lose capacity faster), and loud fan noise. I have a 2018 Intel MacBook Pro and it has all of those problems.

Apple solved all of these problems when they dumped Intel and rolled out the Apple Silicon M1 Macs four years ago. ARM-based Apple Silicon processors can achieve high performance at far lower power usage than Intel processors, so they get hot a lot slower, at a rate the laptop cooling system can handle, so they can sustain maximum performance for longer while running cool and quiet.

If you see high heat with Lightroom Classic, one big reason might be preview generation, because that is currently all done on the CPU, and generating previews in parallel will make all cores busy (and hot). Currently, GPU acceleration only helps in the Develop module and during Export; for most other things the power-hungry CPU cores will get hot.

The far lower power requirements of Apple Silicon mean that, for example, I can work all day long in Lightroom Classic on my M1 Pro MacBook Pro and it stays cool and quiet, and the battery lasts several hours longer than on my Intel Mac laptop.

This means I generally agree with what Apple said, if they meant this:

High performance on an Intel Mac: Yeah, it’s gonna get hot, not much you can do about that.

High performance on an Apple Silicon Mac: Much less of a problem, or maybe not a problem.

(And before any PC users get annoyed with the comparison, the latest Intel/AMD processors are somewhat improved and Lunar Lake might be really promising when it gets here, but the big news on the PC side is that the new, shipping ARM-based Windows laptops can potentially deliver power efficiency and thermal benefits comparable to what Mac users get with Apple Silicon. The catch is that at the moment, Lightroom Classic does not yet run natively on ARM Windows PCs.)

It's a design flaw of the last few years of Apple Intel Macbook Pros that many have complained about -- a high-end laptop should be able to run at high utilization indefinitely. I vacuumed the vents and rested my Macbook on two strips of corrugated cardboard to let air flow underneath, and once I had to take the Macbook to a technician to clean out the air ducts and fans inside.

And you have inspected thoise air inlets on the MACBook?

Unfortunately this can be a side-effect of the higher-performance processors. They generate a great deal of heat. This is one big reason that Apple switched to the newer design of Apple SIlicon.

You might consider a cooling mat or stand, many of them have fans and can make a big difference. Also be sure that the computer vents are unobstructed and not clogged up with dirt or hair and that the fans come on when the computer heats up.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
