I'm a user on a 2019 16-inch MBP (MacBookPro16,1) who hopes to move to Linux as my base OS on this hardware full-time over the next 12 months. ( https://github.com/Dunedan/mbp-2016-linux ) This is because I honestly cannot find a laptop with the combination of 64+ GB RAM, a non-NDIVIA GPU (edit: to clarify, this is because of NVIDIA's notoriously bad compatibility with Linux), and other premium hardware aspects like…

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 decent experience. You'll know this already, depending on how deeply and regularly you use Linux.

You guys are fighting the good fight for everything that owning hardware and being a user used to mean. Thank you.

I never understood this sentiment, if people choose to pay their way into a walled garden, why should they still care about hardware ownership/repairabilty, etc.?

Probably comes down to definition of choice. Up thread someone else is describing how a particular macbook is the only hardware meeting their criteria but the OS is hobbling them.

Clearly the majority has won thus far and Apple is not restrained in any way. But I have the right to a differing political opinion, and when the majority shifts, your freedoms are not encroached, just like when the majority of people decide smoking should not be allowed in airplanes.

That’s a bizarre analogy to me, and you’re implying a symmetry to the situation that doesn’t exist. I want to be able to buy a product that has the properties that I want, and I want you to be able to buy a product with properties that you want (in part because I also want and own products with the properties you want). You want the only option to be products made with the properties you want, so that other businesse…

The condescendence is really unwarranted, it is a simple idea that purchasing options are affected by political choices of others. To give a symmetrical example, you are not allowed to purchase completely safe recreational drugs, because of the opinions the majority holds on their use.

The metric you use of avoiding "restricting freedom" is a strongly ideological stance in itself and is not a natural goal political systems strive for. You might value some flavors of individual autonomy and imply they have an universal vocation by calling them "freedom". I might favor other sets, such as the restriction of corporate power and consumer empowerment, and call those, in turn "freedom", see for example the GPL ethos. Both sets of political views are legitimate and can be pursued in a democracy.

Hi guys, I am part of the team working on all things T2. [1] The checkra1n support is just in a PoC state, it will successfully exploit and boot the T2.

I hope you have reported the issue to Apple so they can fix it ASAP ?

They are well aware of the issue and have been for some time. There’s not all that much they can do to fix this, although they have certainly tried.

It's a trade-off. I buy MBPs for the great form-factor and OS, not for the walled-garden shenanigans. If those shenanigans can be somewhat reduced, the trade-off balance looks better.

This is interesting; does this mean Apple isn't enabling Intel Boot Guard, relying only on the checks enforced by MacEFIUtil?

Fantastic work, by the way.

What's your experience been with amdgpu?

"if people choose to pay their way into a walled garden, why should they still care about hardware ownership/repairabilty, etc.?"

I don't like the walled garden but i still brought a iPhone because iPhones get updates for really long time(3 years minimum). Iphone SE(1st gen) released in 2016 got the iOS14 update.

You mixed that reputation up with Lenovo thinkpads. Apple keyboards break down after several years with the touchpad and butterfly keyboard disasters are even unusable afresh. You cannot replace anything, and are way overpriced. Thinkpads on the other hand are like Toyota's

I have 10 and 15 year old iBooks and MacBooks and MacBook Pros with intact keyboards... You mixed the issue with the butterfly BS keyboards in the past 2-3 years with the old Apple keyboards (which didn't just "break down"). The resale value…

> with the butterfly BS keyboards in the past 2-3 years

Sadly 4 years now, they started in 2016. It's the main issue blocking me from buying another MBP - this keyboard broke when it was already out of warranty, I really don't want to risk it again.

eh, my 2013 rMBP is kicking a long pretty well. Kinda sluggish but no issues with the keyboard. It's been dropped a few times too and the screen cable disconnected at some point from a fall but was an easy fix.

2012-2015 rMBPs are the best laptops ever produced, imho. My 2012 rMBP has been passed down to my brother, with a new ssd, and still rocks.

Why Apple had to mess with that perfect formula, I will never understand. I blame Ive.
