It's more Intel claiming they could meet Apple's requirements (get to 10nm) and then not meeting it for 4 years. This is a simplification, but I can't imagine why Apple would have designed the 2016 15" MBP (which now doesn't even exist) for a transition that would only start 4 years from its introduction.

I tend to agree with that, I don't think that they took steps to minimize the performance of the Intel systems back in 2016. I do think that they designed the current MacBook Air chassis with a cooler CPU in mind, and I have no idea why they built the heatpipe they way they did in that model
. I expect that Apple tests the heck out of the products they sell, and due to the push of being ever sleeker, thinner, they sacrificed performance for design, knowing that the Intel chips would be fast "enough" even when they weren't running at full performance (for the Intel design). Now with their own Apple Silicon, they will be able to push the performance AND design, and optimize the heck out of macOS, and allow things that just would not be possible on an existing Mac with in Intel-based system. If you (or anyone) is curious, you should read iWoz (https://www.amazon.com/iWoz-Compute...?dchild=1&keywords=iWoz&qid=1606235203&sr=8-1), as many of the design concepts that Steve Wozniak used for the Apple 1 and 2 computers, are still demonstrated by what Apple does today.

Very interesting. There is a lot of truth in that!

Message app crashes after sleep, closing and reopening does nothing, have to restart machine, email window wont appear, have to close and reopen app, dual monitors is awful, windows just randomly go wherever they want, strange buzzing noises on sound when using hubs, iphone takes forever to appear in finder, have to lower security by rebooting into recovery in order to install third party apps like paragon, safari sometimes displays a blank page. this is my list so far.

All on M1 Mac? It's strange considering all rave reviews that I saw on web. Probably can be a failed Mac?

So @Carrotcruncher, exactly why did you get an M1 Mac ? The Bold highlights where added by me.

I just upgraded to catalina on my mac, got the same issue, all my artwork is gone, I have made a decision that when all my overpriced Apple garbage reaches the end of its life I will not be replacing it until the greedy moron in charge is gone and someone who puts quality and the customer first is in charge, if you value money as a sign of success yes he may be great but he isn't and never will be Jobs, he is greedy and has zero attention for detail.

I am waving goodbye to Apple, no o2 monitoring on aw5 despite the sensor supporting it, this could have been given to us via an update, drip feed one feature at a time for maximum profit, this company doesnt give a darn about its customers or its reputation, Tim Crook is a greedy slug, I dont like Apple any more and I dont trust em, I am never buying anymore of their overpriced products.

I just bought my first MacBook and I am getting rid, it’s awful, I have exactly the same issue and there is no solution, if you use the pathetic separate spaces solution the entire desktop disappears on the main laptop display! It’s this kind of 1990s software that is making Apple loose the fight against windows, if I had known how bad macOS was and how badly dual
Display was implemented I would never have got this garbage

Wow ! This has completely put me if buying a new MacBook, I won’t be buying one until Tim is gone, the man is a cash obsessed maniac, I remember Steve saying “We don’t ship junk”
Those days are gone people, looks like they now only ship junk !

Also had a weird thing happen today, plugged in iPhone 11 last night to do an encrypted backup, all appeared to go fine, went to be last night phone was fine, woke up in morning and every app was crashing as it was opened, nothing would launch except safari, I could make calls etc but no app would launch, had to do a DFU restore, weird eh ? phone is on latest os and Mac is on 11.0.1

Don't take it as an offense! The same thing happens to me too but then I always fall for it and buy anyway ?

?. Anyway I cured the dual monitor problem, was a dodgy HDMI lead so that explains the flashing random windows, hopefully the others will be fixed in a software update, Im tempted to install the beta just so I can help report these bugs and get em fixed

What do you mean for dual monitor?

Thanks @Yebubbleman!!! Very good explanation. My concerning is related to the code optimization; let me say: If apple will write certain code to make something on MacOs, maybe it is possible to make some kind of programming choose in order to obtain optimal performance on M1 instead of Intel?
Second question: can you give me an overview of T2 chip? Why does the T2 chip bring it closer to an M1?
Click to expand...
Regarding your first question, the answer is in the form of "Universal Binary 2", universal binaries that have both 64-bit Intel code and Apple Silicon code. macOS will see which architecture it's on and load the code for the appropriate architecture. That's how you'll get optimal performance on Apple Silicon (M1) vs. Intel and vice versa.

Regarding your second question, the nitty gritty details can be found here: Apple T2 Security Chip: Security Overview

But the short of it is that the T2 is the start of Apple starting to consolidate Mac logic board components that were previously separate components into a single chip. The T2 didn't have CPU or GPU functions as those were still handled by the Intel CPU (and AMD GPUs on the higher end Macs like the 16" MacBook Pro, iMacs, iMac Pros, and Mac Pros), but the secure enclave, Image Signal processor, audio controller, SSD controller, SMC, and many other components got consolidated into the T2. All of those are now baked into the M1 as well. You just now have the CPU, GPU, RAM, Memory controller in there too along with the introduction of the Neural Engine to the Mac for machine learning. But it's the same idea; take components that either were in separate places on the Mac logic board and integrate them into a System-on-a-Chip (SoC) and have that govern more of the Mac's functionality.
