MacBook Pro Overheating Since New Update

Hello.

I have a MacBook Pro 15in 2.3 GHz 8-Core Intel Core i9 (2Gb hard drive) which has been working beautifully for 5 years easily managing both Lightroom Classic and Photoshop simultaneously at speed - I usually go from one to the other (and back again) at will. Ever since the update last week, when I load up LRc the machine's fan comes on, gets louder and louder and hotter and hotter until the machine powers off. I'm being told by some that the intel processor can't hack it , but it's been running perfectly without a hint of lag up until now. I've had to put desk fans under the machine to keep it running just to get my work out for client deadlines which seems to work for now but of course I can't trust it out on jobs without a fan. Anyone else having a similar experience? Any help please would be appreciated...!

Thanks so much for this amazing advice, this is all great stuff that I wish
I could try but annoyingly things went from bad to worse when after the
computer went through about 3 cycles of restarting and shutting down I
finally got the black screen (white Apple logo) of death. I managed to get
the important stuff off the machine using the link up with my wife’s
MacBook using the T function. Apple have looked at it and told me it’ll be
an expensive fix. I’ve had to go and buy a new laptop, at great expense,
but am going to take it to a local repair place and see what they can do.
Hopefully if fixed I can sell.

Thanks again for all the advice.

It can help to track down more about where the problem is coming from. For example…

Fans turn on and get noisy only because internal temperature gets too hot.

The main reason for internal temperature getting too hot is because of extended high power consumption by at least one component (CPU, GPU…).

So, for example, you should open macOS Activity Monitor (it comes with every Mac, in the Utilities folder) and look for what is causing high power usage.

In the CPU tab, when you sort the list by % CPU, is there an application using a very high percentage of CPU? (Remember that in macOS, 100% equals 1 CPU core, so a 6-core CPU would be maxed out at 600%.)
In the Energy tab, when you sort the list by Energy Impact, which applications are at the top?

If Lightroom Classic is the application using a lot of CPU and energy, and it only started recently, then the cause could be the kinds of known sync issues that Ian Lyons is talking about.

If Activity Monitor tells you that the high CPU/energy consumptio is because of another application or process, such as macOS Spotlight, kernel_task, a specific web browser tab, or something else gone awry, then you go and troubleshoot that.

If there are no applications using a lot of CPU or energy, then maybe your vents are blocked and need cleaning. In other words, if they used to be able to cool the machine under low loads but now they can’t because of reduced air flow.

By @Conrad_C

Or if Lightroom Classic is using a lot of CPU or GPU, it could be getting hot for other reasons, like dust buildup in the case, or fans not working, or other things, as I was trying to say. May or may not be because of sync issues. People have been reporting fans running loud and computer gets hot long before this sync issue.

That’s what I said at the end of my post. But I think it is far more important to go through the other steps first, to use the Mac tools to verify that they’re chasing down the right problem. Because it‘s somewhat common to blame the wrong thing, and spend time trying to fix the wrong thing, when the actual cause is something else.

If there really is a difference between Lightroom Classic not running hot before and now it is, then it’s more likely that the cause is the sync issue or maybe (but often not) blocked vents.

Regardless, it’s an unusual problem. Under normal conditions (that is, the computer isn’t out in the sun on a 95F day, or in front of a heater), a current Mac or PC should never have to power itself off because it got too hot. Thermal management at the OS and hardware level should be able to take care of that using the cooling system, and if not, then by throttling down component performance. It should not be possible for any non-Apple application (such as Lightroom Classic) to heat up the Mac so much that it has to shut off. If the OS and hardware cooling loop is not working, something else might be going on, and it might be at the OS or hardware level (and yes blocked vents are one possibility there).

Your cooling system is not working properly. If you can open the case, vaccuum out all dust. Make sure all the fans in the case (if there are any) are running, and make sure the vents in the case are vaccuumed out and clear. Make sure all the vents are not blocked by furniture or walls. Consider buying a laptop cooling device.

Please post your 'System Info'. This can be obtained from the LrC Help > System Info menu item.

Can you also confirm whether you have Adobe Cloud Sync enaabled. If yes, then try pausing it using the cloud icon at top right corner of LrC UI.
