I have had exactly same issue, though with third party service. They replaced the screen, and when I came home it froze one time, and started beeping 3 times indicating ram problems. Because it was iMac, i had a chance to rearrange RAMs to boot up but it still was freezing up at times. I ran memcheck, found errors, and then figured out which ram planks was faulty. The thing is that the issue started long before that,…
I've fixed two MacBooks with "faulty" RAM for family friends, it was a funny experience... The first one just needed a cleanup and some new thermal pastes. But afterwards, when I was test driving the laptop, I found the machine started to crash randomly - the OS was a fresh install. And later, I found whenever I put the laptop on the metal chassis on my PC (it was on the same table), it could trigger a kernel panic.…

Apple is very much a consumer level company. I’ve seen reviews quality wise that they are average with hardware failure rates. They do try... for instance I’ve heard the reason they always charge more for RAM is labor costs from running additional tests to fail chips other companies ship.
>I’ve heard the reason they always charge more for RAM is labor costs from running additional tests to fail chips other companies ship. Which is false. Apple uses the same off the shelf DRAM chips from established manufacturers found in any PC/Phone/Laptop. Unlike Flash storage, there is really not really bad performing DRAM per-se, just defective, And apple is no guarantee of free from defects with RAM fault in MACs…

I don’t know, but if you’re shipping mainboards with soldered on RAM it could be worth it to test the modules before soldering to reduce the amount of returns where you have to replace the entire board.
That doesn't mean parts with some defects don't sneak into the final products but the rate is low enough that testing each chip you receive is not monetary feasible for consumer products so you just test the final assembled product to a degree, but even then, brand new Apple products are no strangers to having their mainboards replaced for a defective chip in the warranty period. Just ask Luis Rossmann or people working at the genius bar. That's why everyone recommends you get Apple care.
So the theory that Apple thoroughly tests each chip that goes in their products is false. It would be too expensive and eat into their fat margins.
What you do test, is samples from each batch you receive, to make sure your supplier did not pull a bait and switch and replaced your contracted parts with lower quality ones under the same part number and hope you would not notice but this is more common on low margin parts and Chinese suppliers are notorious for this since for them it's just regular business practice and see nothing wrong with it.

For me, OS stability, in decreasing order, has always been: 1. Linux 2. MacOS 10. Windows
Hard to say but for me I would say: 1. Windows 2. MacOS 3. Linux I had more crashes on Linux than any other, all related to the Gpu driver (intel iGpu), and it really depends on the kernel version but newer not necessarily means better. In a VM with i3, it never crashed. But regarding hardware support except for the Gpu, I had better experience with Linux than Windows on the same machine. On Windows my mouse is stutt…

Seems Apple managed to eliminate a major source of defects by removing the DIMM connectors from the MacBooks.
It's sad to say but I've had more hassle with Windows 10 than any previous (NT based anyway) release. 2000, XP, Vista, and 7 all served me well. 10 has done everything from deleted my files (thanks, October 2018 Update) to DESTROYING my Linux boot loader that was placed on a separate hard drive.. it has no business touching that! I always looked at Linux as not being worth the hassle.. now it's not worth the hassle t…
I have a very strange SSD related bug at the moment on that Windows version too: I've downloaded my Google Takeout Backup, so 74 4GB sized zips. After I was done extracting them and storing them on Dropbox, I tried to delete the zip files, but my machine froze without so much of a bluescreen. After a hard reboot, I could reproduce the behavior. I can still change the focus of apps, but everything that requires the ss…
Dropbox Might that be your problem, or part of it? Not 100% sure, but whenever I access machines with Dropbox all kinds of weird things happen like there's a ghost in the machines. E.g. deleting a directory managed by Dropbox through explorer consistently results in all its subdirectories and files deleted, but the directory itself remaining there, requiring deleting it again.
Regarding the parent poster, on Windows Smart Sync is enabled and, while extremely useful (and better that Onedrive’s equivalent IMO), it did cause issues in the past. Since it seems to work as a file filter, it can cause some issues. That being said, I haven’t seen those in a while.
