Looks like I got another defective M4 Pro? Super...

[xraydoc]

Returned my 14” bought a MGK for my M4 iPad Pro.

My M4 iPad Pro pretty much serves as my laptop, and my M3 Max MBP serves as my desktop. And I stopped using an actual desktop machine for a desktop several years ago (at least for my personal Mac; my WFH PC doesn't count since it belongs to my employer anyway).

It could be due to cooling. My MacBook Pro sits on my existing laptop cooler which sits on a LCD monitor arm tray. That's why I originally asked if your issue is thermal throttling

This is the laptop cooler I use originally for my Windows 10 laptop Lenovo X1 Carbon gen 6 which died https://www.amazon.com.au/dp/B00FPR8FLY. It's large enough to cool the ports of devices on either side of a 14 inch laptop as well. Definitely served me well for the past 7+ years

So maybe your issue is CPU thermal throttling + on battery auto performance ?

These are my performance and efficiency core CPU clock frequencies after Cinebench 2024 run

edit: actually maybe it's due to performance modes + thermals

out of box Macbook Pro set to auto for on battery and on AC power adaptor modes. My above run was on AC power adaptor mode with high performance

here's on battery with auto = 1545 and high performance = 1607

on auto CPU performance cores hovered around 3.3-3.35Ghz with efficiency cores around 2.59Ghz and fans pegged at 4900-5330 rpms

on high CPU performance cores hovered around 3.57-3.66Ghz with efficiency cores around 2.59Ghzand fans pegged at 7200-7840 rpms

Which stats/perf monitoring tool is that?

That's not how things works. You can't receive a working processor with individual defective cores. Either the whole thing works or it doesn't. There are ways to individually disable cores to bin the chips and use units that require certain cores to be disabled, but that requires imbedding special microcode into the processor itself during finalization. It's not a situation where one core (or more) can just not work and have that slip past QC testing. You cannot be in a situation where you've paid for a 14-core model and receive one where only 13 are working.

Okay thanks, this is good to hear that I did not receive a defective CPU.

Macbook Pro's screen and keyboard are delicate. Dust will scratch the screen if left on there and it will also ruin the keyboard if it gets under the keys.

Really? Good luck keeping dust off it. There isn't a chance in hell you will be able to remove every spec of dust from your laptop unless you lock it in a clean room and never use it.

News flash, every laptop screen and keyboard is delicate once you get into the sub 1" thick market.

All that that is needed to make any laptop last long is to just have basic things you don't do while using them.

If I may ask, what else do you intend to use the laptop for?

Complaining.

I have a home office for my business, prefer a desktop in it. 24” M1 iMac now.

Wiping it down with a brush before closing the lid each time helps immensely. And yes dust will damage the keyboard and screen over time if left there to accumulate over time.

I don't ever dust my M1 Pro work laptop and you should see how much dust has built up in just over a years time from not even everyday use.

It's probably no where near the dust that gets inside my Mac Pro.

If you're getting that much dust in yours, I would recommend using a mini brush to wipe it down each time. Well worth the $6.

Little brushes don't work on towers.
