I agree. I suspect that they got locked in with the design decisions that they made with the 2016 model. They have limited power in to 100W by using TB3. They have limited power out (heat) by a very thin design and fans that spin slowly. Now Intel has a chip that can ask for 150W of power and produce as much heat. The VRMs may well be under dimensioned, but just ramping up that area won't fix a whole lot.
They should set the CPU to operate within the limits of the power delivery system though. And the fan profile to correspond to the amount of heat the CPU is producing. When the fans spin at max it seems like the cooling is not too bad. Though if the VRMs are not getting any cooling, that's not really great.
See how I was right? Overreaction. Fix available.
Oh, but you’re probably not convinced bc of your inside knowledge.
You people are priceless.

Or it was just a software issue.
Am I some kind of psychic?

Wow, I made this call like I knew Apple would fix this today.
Apple is very focused on shaving off those millimetres from the devices they dont even consider the thermals, not everyone is gonna do web surfing on i7 Processors, some of us would use unity to make games others would do programming in java. Apple has almost lost us all content creators, current mac lineup not suitable for rendering videos.
It should have never been released with this issue.
Someone who didn’t work for Apple caught it. What does that tell you?
Looks sufficient to me if this fix works, right? I mean, what do you want?
[doublepost=1532453778][/doublepost]
Lol!!! Remember, we live in the real world. I told you it was software the day it happened and that Apple would fix it.
They have already done it. You want it to never have happened? Fine, but how would you rate the response given the fix is already available, assuming it works?
This is the type of support I was trying to convey. Apple fixed it and no one will remember this. The watch had an issue with WiFi networks and the Cellularsignal, but they fixed it, it’s selling great and is a great product.
Have you ever worked with computers extensively? Sometimes replicating an issue isn’t as easy as it seems. Stop being such a brick wall on this.
Heh, I don't care. I don't have an i9 and I'm not interested in getting one. You still have a chip that can draw 150W and will be limited to maybe half of that, which of course limits its performance. But maybe they fixed the more pressing issue of VRM overload, we'll find out soon enough.
You were saying...?
[doublepost=1532454647][/doublepost]
And you were saying...?Lol, good joke
maybe the testers weren't constantly eating cheetos over their keyboards?
I didn't say that did I?
I said that high end processors are usually rated higher because they need to be as they usually are specced higher
In the end inside the same family all processors are more or less the same with their names being a marketing marker for their positioning.
In the same family, same generation, an "higher end processor" won't be specced on the low end of thermal envelopes and a manufacturer that wishes to use one of those processors better take that into account.
What people will remember is what goes on between "Stuff happens" and "Apple fixes it".
In this case:
Is every problem report going to be met with defensiveness, denial, and "gaslighting" from Apple defenders? But all that is perfectly ok as long as "Apple fixes it"? After looking back on previously reported issues which were corroborated, one would think that maybe the community should be less defensive and less dismissive when new issues are reported.

Pretty much. This type of error isn't really a showstopper.
Stuff is broken for years on Windows machines. Samsung ships a phone with an exploding battery.
I don't even blame those companies either. Stuff happens...it's about how you respond. No company is perfect, but Apple does a better job than most. That's the whole point here.
Generally, I agree with you. No one wants or needs to add drama to tech problems. However, where I leave off on a happy ending for Apple fixing things is the number of things Apple has introduced to the public that need fixing. I thought we were paying a premium for Apple things to work better. That used to be the case.
So much for needing to redesign the motherboard. Lol. Leave the computer designing to the professionals. Don't quit your day jobs.

> I figured it was a bug when some tests were showing that performance improved on the Core i9 15-inch MacBook Pro after disabling two of the six cores. Apple told me that this thermal bug affects all new MacBook Pros — not just the Core i9 model — and older models are not affected. Anyone with a new MacBook Pro should now see the fix via Software Update.
Well, your statement seems to be rubbish when Apple says this:
"According to Apple, this issue actually affected all versions of the new 13-inch and 15-inch MacBook Pro models regardless of the processor inside, and was the result of a bug within the computers’ thermal management systems. Apple has since added performance results for the very same task Lee attempted on video on its website".
Intel has NOTHING to do with this issue, so stop your nonsense.
Lets take off the rose tinted glasses.
I've been an Apple fan for decades and they have had issues troughout the years. The G4 Cube was riddled with overheating issues almost 20 years ago. MBPs from 2011 utilising AMD graphics had pretty serious graphics card issues. The iPhone X had issues in cold weather at launch. We could go on.
When exactly was this "once upon a time" you speak of?
The YouTuber that Apple worked with on this fix (Dave Lee) still says the i9 performance could be much better if the casing were better designed to dissipate heat. Also, Louis Rossman, a repair tech, demonstrated how the fans in MBPros are set to very high heat thresholds, in order to keep the laptop quiet. These hardware decisions by Apple are not good ones for performance and longevity.
So, Apple are running up against a brick wall here..
They want to give users the best performance and best chips they can provide, but at the same time keep it cool.
Most people would get new Mac's anyway every 4 years or so, so Apple probably doesn't see this to be a problem, when your dealing with "a confined space"
I'd like to see test on on these chips but in non-Apple Mac's laptops so see if they experience the same. That'll tell you if its Apple issue in same conditions.
