That more or less proves the point. There is very strong demand for old MacBooks because they last. Planned obsolescence is needed to ensure that people upgrade. That can be done multiple ways. This is just one of the approaches and will of course take time to settle in.

Planned obsolescence just means artificially shortening the upgrade cycle. That's it. And Apple has been doing this in the Mac world through different methods.

What do you mean? As fas as preventing a thief from using a stolen Mac, it is under the owner's control.

If it was about preventing theft, then the rightful owner could modify the keys and software without any worry. But they can’t. Because it’s not about giving you control, but about controlling you.

The bits about "preventing theft" and "user security" are secondary justifications. It's the same basic pattern as all authoritarianism - the main goal is the control itself, which then provides trickle-down stability.

I'll be interested in trusted hardware when I see an implementation that actually puts the device owner into the privileged position, rather than reserving it for the device manufacturer.

Why without an Nvidia GPU? Just go with an XPS 15 or 17 and embrace Nvidia on Linux. I have three developers running Linux on HP zBooks with Nvidia GPUs without any hassle. You can also buy any newer Thinkpad (my recommendation). They are also available with AMD CPUs. It's pretty easy to buy Linux laptops these days.

Everyone in the Linux space, from what I regularly read and hear, says that NVIDIA GPUs are notorious and a bad idea for using Linux. They're saying go with AMD. (As well as Ryzen instead of Intel for CPUs, where possible.) The only open-source nouveau drivers are absolutely terrible, I can attest to that fact myself. There's several benefits to not relying on NVIDIA's proprietary and non-in-built drivers for a decen…

I've used nvidia GPUs on Ubuntu with the proprietary drivers.

In my experience they're largely OK. There are some rough edges - you'll struggle to get Steam and CUDA working at the same time, for example - but no showstopping problems.

I certainly don't have a debilitating kernel panic every week :)

same website :D 70k/year is 5k monthly which results in 44k post tax. thats 3700 a month post tax. only us austrians (and i think italians?) do this whole nonsense of 13/14/15/16th salary

You're right, I forgot to divide the 13 and 14 salary. Even with those included, I'm at 2750 NET per month(49K/year before taxes), which is still below the 3000+ average claimed above and devs tend to be above average paid(usually). Or everyone else makes 3000+ and I'm underpaid, who knows. :D Sucks that people in this country don't usually discuss salaries because reasons.

you are right, just redid the calculation and i am at 33k post-tax too. i guess i had the family bonus still active when i did it last time.

nobody discussed salaries in germany/UK either though. wasn't just a problem in vienna for me ;)

how are the salaries in vienna these days for software devs?

> Filevault and by extension Touch ID are more or less crippled Sorry, what does this sentence mean? That someone with physical access to my machine can now unencrypt my FileVault encrypted hard drive?

Some one from Apple, I'm sure you read this. Please answer this ASAP. I rely on mac and FileValute for professional use at work. Need to know the state of this exploit.

Bow for the chosen one!

Why do you believe it's moral for you to do work which is making people's data less secure, helping law authority crack iPhones, etc?

It's work which is enabling freedom, something that people are unfortunately giving up far too much of these days...

I will anecdotally agree; I've been a Linux laptop user for... well, 2 decades maybe? and explicitly choose Dell Mobile Precision and/or IBM/Lenovo T-series laptops with ATI/AMD, dealing with NVIDIA graphics is just a pain in the ass once we passed the GeForce era (ish). I'd rather just have/use Intel GPU over them as well, I am not a laptop gamer to need anything NVIDIA offers in exchange for the pain in maintenance…

I will anecdotally disagree. Depending on which distro you use NVIDIA grapics can be quite painless. Using Pop!_OS, I just had to download the correct iso from their downloads page. I believe most other distros have NVIDIA's drivers in their non FL/OSS repos as well. Optimus graphics will even work with the most current drivers.

I’m using Pop!Os (preinstalled) with a sys76 laptop. Works great (can even game) battery life is terrible (though it looks fantastic and can drive a 32 inch high dpi external)

I can switch to built in Intel video for better battery but it requires a reboot. I see this as a stopgap. My home machine has an amd video.

Nvidia gpus require proprietary drivers that are only provided for specific distros and are only supported for a small amount of time. And if you find any bug well tough luck, nobody can help you. For a work setup that you rely on someone else in the company for support they might be fine but I wouldn't recommend them for a personal setup. All this is on top of the fact that they still don't support Wayland and you h…

10 years of support on the latest driver branch (current branch goes back to the 600 series, and the 400 series was dropped in June) doesn’t exactly seem like a small amount of time.

Go back and do your homework.

Showing security problems is the opposite of making Technology less secure. Maybe ask Apple why they think it's a good idea to have closed source special chip at all.

> The biggest competitor for new MacBooks are old MacBooks. Maybe true 5-10 years ago, but not true now.

What has changed in the last 5 years? MacOS users have no legitimate alternative if they want to keep their desktop on macOS. If you want a macOS system legally, there's two options, either buy a new Mac, or an old one.

The competition has just done a lot of catching up in the last few years.

Hardware: Other vendors have trackpads with multi-touch (which for me was one of the most amazing things about the first Macbook I ever owned), super high-res screens, and other such features these days. The form factors are thin and stylish as well (there are other aluminum unibody laptops these days).

Software: MacOS has gotten worse, Linux distros have continued to catch up, both in the look and behavior of the OS itself but also in terms of the app ecosystem, esp with companies like Valve spending the big bucks to get lots of games running well on Linux. Speaking of games, MacOS continues to suck when it comes to gaming anyway – so for example I do a bit of gaming on my new MBP 16" and the mild chore of dual-booting continues to irk me. I also splashed out for the 8GB GPU upgrade and performance is still not great. Not quite enough for me to make the switch but I'm not a very hardcore gamer. I know people that need a workhorse a bit more than I do (professional video editors and such) who have recently (last 5 years) made the switch from macbooks to things like razers because they want to be able to really push through serious workloads on the go.
