jbstack•1h ago
I've never personally understood the point of macOS for power users (other than cases where you're required to use one e.g. for work). I can understand it for casual users who just want something simple that works for basic tasks, but what does macOS offer a power user that Linux doesn't, and which makes it worth sacrificing the ability to run your machine the way you want? In Linux you'd solve OP's problem by just building up from a minimal distro like Arch or NixOS.

For me, battery life and power management – even with the number of services that macOS runs. I run Asahi Linux when docked, but on the go I estimate I get a warmer lap and about ~1/2 hr less.

A lot of users still like the mix of a good UI for most tasks, while being able to do a lot of power user stuff without an added layer. Plus many will choose macOS also for the hardware, which support for new chipsets is still rather WIP under Linux.
vladvasiliu•58m ago
> A lot of users still like the mix of a good UI for most tasks

This is funny; it's actually the main reason why I asked for a PC when I was up for renewal at work, so I can run Linux on it.

I truly like the hardware of the mbp, especially the screen (don't care about battery life, I mostly use it at a desk with power nearby). The OS itself is fine, since it can easily run most of the tools I use. I also like how it handles special characters (I can easily type French on an US-ANSI keyboard) to the point that I've implemented that on my Linux and Windows machines.

But what kills it for me is the UI behavior. The window management drives me crazy, especially when multiple screens are involved. And there are quite a few aggravating issues, like being unable to control the audio output of my screen's speakers (connected through DP), being unable to turn off external screens (sometimes I just want to use the power of my monitor, which has an integrated KVM).

Yeah, I know there are programs trying to fix these, but I have to go out of my way trying to find them, and then they're hit and miss. On Linux, everything works as expected (though, granted, it's possible I've won the hardware-compatibility lottery, since it actually works better than on Windows).

physicsguy•1h ago
The big thing for me has always been (a) reliability of the hardware (b) good performance/battery trade off (c) nix-like environment.

In my prev. job I had a windows laptop with WSL2 though and I actually was super productive with that. But the laptop hardware offerings at the same price point are rubbish, just not very robust. Linux machines if you're in a corp and want one in the next 6 months are usually even more restrictive on hardware than they are on Windows.

JodieBenitez•1h ago
> what does macOS offer a power user that Linux doesn't

Your definition of power user may vary but for me:

    - Especially for laptops, good integration with hardware (and good hardware), energy efficiency, power management
    - Support from commercial software vendors
I could probably use linux for a desktop machine, that would work ok. But it's a no-go for laptops. And I've tried... and try regularly...
pseidemann•1h ago
Perfectly working drivers.

As a power user, I want to use, not to fix, my tools.

I might tinker sometimes, but that is unrelated for me.

oneeyedpigeon•58m ago
Exactly this. The question pretends that there is a whole group of "power users" who all do the same thing, but that couldn't be further from the truth IMO. There are users like me who program and don't want to spend forever configuring audio driers, etc. There are power users who like to tinker. And there are people who do a bit of both, to every extent on the scale.
nicoburns•1h ago
> what does macOS offer a power user that Linux doesn't, and which makes it worth sacrificing the ability to run your machine the way you want?

Primarily much better compatibility with graphical apps. Microsoft Office and Adobe Creative Suite are two that many people need access to. Both have first-party offerings on macOS, and somewhat poor support via wine on Linux.

With Apple Silicon, the hardware is also particularly excellent. And only runs macOS well.

Haha right. They last so much longer than non-Mac laptops from a hardware PoV, and especially how long they end up being used. That's why they retain their second hand value so much better than Windows laptops, because you can buy a Macbook of a few years old, know exactly what you're getting and that it will last another few years unless you're extremely unlucky.
stabbles•59m ago
It just happens to be so that hardware which power users like to use comes with macOS installed.
sakisv•58m ago
For me it's quite simple: It works and it stays out of my way.

I've owned a macbook since 2010, with a short break during the touchbar era when I got myself an XPS with windows which I dual-booted with ubuntu and later a system76 that comes with their own flavour of Ubuntu, called Pop! Os.

The situation in windows (windows 10 at the time) was abysmal. Completely incoherent UI, settings spread across different menus, ads in start menu, slow and broken search, constant nagging to update windows, to update the drivers, to tell me that the drivers have been updated, to install or update my antivirus, etc. These were not things that I installed myself, these were included with Dell's setup of the machine.

On the system76 laptop things were different. Things were calm, I could configure everything as I wanted and things worked. Until at some point I installed a new version of something, which had nothing to do with sound, but it broke sound, just as I was preparing to join a meeting, and just as we were going into the second phase of lockdowns in late 2020 so online meetings were here to stay.

My macbooks are reliable. I've got the M1 as soon as it came out and I never got a single issue with it. I've upgraded twice (I think) across major versions and everything worked. I don't have to worry about it leaving me hanging when I need it.

(And that's not taking into account things like build quality, touchpad quality, battery life, silence, etc)

In the end of the day, I do a lot of debugging as part of my work. When I don't work, I want to choose what I will be debugging, not have it forced on me.

And don't get me wrong: I see where Apple is going, I know that they're a greedy company that want to maintain their iron grip and have the final say on what we can and cannot do on our machines.

However, for me for the time being it's the least bad option.

timeon•51m ago
> It works and it stays out of my way.

This was reason for me as well. More than decade. Unfortunately it is not the case anymore.

Hardware is still best (in my opinion) but software is not.

graemep•48m ago
One problem with system76?

I have very few problems with linux, despite running a fairly unstable rolling release distro. MacOS does have problems. I have no idea whether its more of less reliable, but going on personal experience is not a good sample.

flowerbreeze•17m ago
I do like the build of Macbooks and especially the solid casing. Unfortunately I could never get used to MacOS even within 2.5 years and it was not quite as reliable for me as it is for many others.

XCode installations failing, Docker installation failing after an OS update never to work again without completely reinstalling OS, plugging in headphones would crash the Macbook (until OS update 6 months after I got it), video calls slowing to a halt, if sharing screen etc.

Also there were some things I just never got used to in Mac like window tabbing & minimize working in a Mac way. Maybe if I hadn't had a personal laptop that used Linux at the same time, I would have gotten used to it a little better, but I just plain hated the way it worked.

To be fair, I think it was still more reliable than varieties of Windows, especially the later ones! If tabbing worked more like under Windows and it allowed a bit more configuration, I might be using Mac these days.

That leaves Linux. Although it's not flawless neither after configuring Debian + i3, it works exactly like I want and the same installation has been reliably working for 5+ years. However, getting to the setup that just works certainly took several tries and depends on laptop compatibility, so... No ideal choices exist right now I think. Just luck and what someone is most used to in the end.

closewith•54m ago
> what does macOS offer a power user that Linux doesn't,

Quite simply, an OS that you don't have to think about. I moved to MacOS from linux after seeing my co-founder use their Macbook basically without any problems, much longer battery life, nice conveniences like shared clipboard and wifi password sharing, airplay, Airpods integration, better screens and font rendering, perfect migrations to new hardware, etc.

While I learned a lot tinkering with linux for a decade, at some point you can't beat something that just works.

citrin_ru•48m ago
> what does macOS offer a power user that Linux doesn't, and which makes it worth sacrificing the ability to run your machine the way you want?

Access to Apple ecosystem - iCloud e. t. c. If one uses iPhone it's quite convenient to have access to the same cloud services from a laptop. FindMy is a big one for me - if I lost or misplaced my phone I can use FindMy on Macbook to locate it. While it's technically possible to use FindMy via web you'll need the phone as 2FA which is not an option when I'm trying to find it.

GeorgeOldfield•47m ago
battery management, ARM chips, SoC ram, only decent trackpad in laptops, only good audio output in laptops (3V RMS for 150+ Ohm headphones. literally no other laptop has it), etc. These things are only possible on Macs because of economies of scale. But the most important part, to me, is software. again, economies of scale -- almost every polished app comes to Mac OS as the first OS because of the monetization potential per install. Then apps for Windows or Linux are often an afterthought or are non-native.

Mac OS is not great, no platform is perfect. Gotta think what is important to you. Are you using your machine as a thin client? Then maybe Linux is fine. Windows is obviously tragic -- zero advantages there.

about the article, Mac OS can be gutted via disabling SIP (I'm doing it on 1 macbook air), but we have so much compute and RAM that it doesn't make much sense for most use cases. I know that some companies do this with minis/studios to make makeshift servers.

jonpalmisc•41m ago
For me: pro & creative apps. GIMP/Inkscape will never replace Photoshop/Illustrator/Affinity. Ableton, Logic, Pro Tools, etc. are not available on Linux and with the exception of REAPER, the alternatives are awful. And even with a Linux-compatible DAW, very few plugins are available on Linux.

On macOS, I can work on hobby software & graphics/music.

These threads always end up with veiled insults like this. Can you really not understand people who use Windows, Linux and Macs? They each have their strengths depending on what you are doing.

> which makes it worth sacrificing the ability to run your machine the way you want

I've use Macs since my first G4 PB, Linux for longer, and used to develop for Windows though it's been a very long time. I've never felt stopped for doing what I want.

> by just building up from a minimal distro like Arch or NixOS

Been there done that. I have too many other things that need to get done to build up a distro. I'm sure desktop Linux has improved since the last time I tried running it as my main computer, but I just not sure what the point is now.

pitkali•25m ago
I got my first MacBook around 2010 because I was tired of fixing suspend to RAM every few Nvidia driver updates on my ThinkPad. Then I paid for a commercial VM to seamlessly run some Windows software I needed for my freelance work as a translator, removing the need to dual boot two operating systems. Everything just worked, and I could focus on things I wanted to do instead of continuing to tinker with the OS itself. And after years of playing with many different Linux distros, I realised that I did get tired of that. Moreover, a few games that I played, actually had native Mac versions. What's not to like?

These days I do have a Tuxedo laptop for fooling around, and I don't even use laptops on the regular, which is probably why it works well enough. That and integrated Radeon graphics, I'm sure.

> To the Unix purist, this might appear wasteful and unnecessary, but macOS isn’t, and never has been, Unix.

I get what they mean, but macOS is even Unix certified. https://www.opengroup.org/openbrand/register/

timeon•56m ago
Yes on paper. Submitted version differs from what customers run at home/work.
yokoprime•44m ago
Im sorry, but i dont buy that. Unix certification has nothing to do with number of processes running or "efficiency"! The OS must be SUS compliant, i.e have all the core interfaces in place, all the correct utilities (awk, grep, vi, sed etc) and theres something about header files, filesystem requirements etc. even if the macOS submitted for certification is super trimmed down, it does not matter as long as its a true subset of what is shipped to consumers.

MacOS is certified UNIX i.e its "UNIX", like it or not. On this point the article is just wrong.

timetopay•32m ago
Unix is both a family of operating systems and also a trademark. The name is overloaded - "Unix" is more than one thing at the same time. In addition, the trademark is "UNIX" and the operating system family is "Unix"

MacOS is both UNIX and also not Unix at the same time.

If the trademark holders decided to UNIX certify my cat, which is well within their legal right to do so, would that make her UNIX?

greggsy•2m ago
Unlike macOS, your cat does not, and will not, meet the industry-accepted standard that describes unix as we know it today.

https://www.opengroup.org/openbrand/register/xym0.htm

greggsy•16m ago
The compliance trope that a point-in-time-assessment can't be used to support a claim is kind of a lazy take. The certification explicitly states macOS v26.0 Tahoe.

While it's true that it wasn't always truly UNIX compliant, they put in the hard yards to become so (albeit to avoid a $200M lawsuit from The Open Group) [1]

I badly need slimmed down macOS for CI VMs. Yeah, some little things can be cut out but most of the time not.

On the other hand, macOS is not that much memory-hungry as one might think. Like, a 4GB VM can start and build software.

thisislife2•15m ago
For those wanting some semblance of control over macOS system processes, consider experimenting with App Tamer ( https://stclairsoft.com/AppTamer/ ). I was sceptical about it but "rogue" system processes, like Spotlight Indexer / Engine, that randomly demanded and hogged 100% of the CPU is now a thing of the past for me, after I used App Tamer to set it to not use more than 20% of CPU resources. It can supposedly stop (kill?) processes too, and I am experimenting with that too. But yeah, I think it's time to dump macOS (thankfully, I am still using an older version so my experience is less shitty).
