I hope Apple currently has a team focused on macOS perf. I worked on the team in charge of improving iOS (13) perf at Apple and IIRC there was no dedicated macOS “task force” like the one on iOS. Luckily some iOS changes permeated into macOS thanks to some shared codebases.

Apple doesn't give a fuck about macOS since 2015.

Ah, Apple. When you can no longer innovate, just start removing features and call it simplicity...

Honestly I'm trying to think of a reason you would WANT to disable OCSP, I'm having enough problems thinking of more than 2 developers I know who can actually articulate how it works enough to evaluate this. Not that it's complicated—it's just mostly invisible. Even when OCSP is a problem, generally you're more worried about issuing a new certificate than an immediate workaround. What are you going to do, ask all you…

How about it's totally ineffective? OCSP is pointless if you "soft fail" when the OCSP server can't be reached. [1]

This is why Chrome disabled OSCP by default all the way back in 2012-2013 era. Not to mention the performance cost of making all HTTPS connections wait for an OCSP lookup. [2]

It's surprising that they don't improve the developer experience for their own developers using their own tools, including hardware.

Apple uses the same tools you do. They just might not be using it like you are; you can find a lot of features that clearly have no reason to exist outside of Apple nonetheless shipping with their software.

> Apple uses the same tools you do.

No. A special directory can be created at the root of the file system called /AppleInternal. Then, if you work at Apple, you can put some special files there that do stuff. I've read somewhere that they are able to easily disable all of this privacy protection crap and other annoying stuff.

Moreover, I've been running Linux for decades now, both in my personal laptop and at work, and Ubuntu has been (mostly) frictionless for me. I'm not an average user, of course, but for most users a friendly distro would work just as well as Windows (browsing the internet, using whatsapp web, watching movies). In some cases I've had a better user experience with Ubuntu than with Windows or OS X, namely seamlessly inst…

I only tried Ubuntu, a few month ago. For the day or two spent with it: - multi-language support requires a lot of work to get to the same point as macos. In particular I use third party shortcut mappers to get language switching on left and right command keys (mimicking the JIS keyboards, but with an english international layout). That looks like something I’d have to give up on code myself. - printer support is not…

Fair enough. I'm not a Mac OS X user so I don't know how it would compare. I can only compare it with my past experience with Windows, and I think it's superior (for me) to Windows circa 7 -- I stopped using Windows entirely at that point, so I wouldn't know how later versions of Windows fare.

Portability is also a fair issue to raise, but it's simply not a problem for me. When I say Linux "on the desktop", I literally mean it: to me a laptop is simply a slightly more portable desktop computer. I sometimes take my work laptop to/from the office, and the battery lasts long enough for that. I'm not worried about longer trips, since I don't use laptops for that. Again, if you do care about this (which is completely fair), I'm aware many Linux distros still have issues with battery life. You certainly can't compete with a Macbook Pro, that's for sure!

I do note that my experience with printers is opposite to yours. Like I said, when trying to connect to an HP wireless printer, Ubuntu autodetected and self-downloaded the necessary drivers; however, it took a lot of patience to get it to work with a Macbook Pro. Today, that I have it configured for my Ubuntu laptop and my wife's Macbook Pro, the Mac will sometimes fail to print (the print job simply stuck in limbo) while my laptop prints reliably. Who knows?

And like I said in another comment, I game (or used to, anyway) a lot with Ubuntu, and many games are even AAA (though they tend to arrive later than on Windows).

So I really have a hard time believing Linux is not "ready for the desktop". It is, and has been for many years now.

edit: one last thing. You mentioned HDPi modes, multimonitor, multilanguage... none of those are for average users. My mom would be comfortable browsing the net, reading mail and watching movies on Ubuntu. She doesn't even know what HDPi is, nor does she want external monitors. (Spoiler: she still uses Windows because she can't learn anything else at this point... I've thought of tricking her by themeing Ubuntu to look like Windows, but that would just be mean).

Xcode (the UI) is able to bypass GateKeeper checks for things it builds. The "Developer Tool" pane in System Prefs, Security, Privacy is the same power. Drag anything into that list you'd like to grant the same privilege (such as xcodebuild). This is inherited by child processes as well. The point of this is to avoid malware packing bits of Xcode with itself and silently compiling itself on the target machine, thus b…

This is life-changing. Thank you!

I wonder what % of their users are developers only begrudgingly sticking around for iOS builds.

Another way to look at it is that Apple is making it harder to run the system in an insecure fashion. You may not agree with that decision, but I certainly appreciate how Apple is looking out for the safety and security of the user. Tangent: as much as some developers hate that the only way to distribute apps for the iPhone is through the App Store, as a user I consider that walled garden of apps to be a real securit…

Wouldn't a sandboxed Zoom downloaded directly from them be equally secure?

It seems like there is a lot of confusion here as to whether this is real or not. I've been able to confirm the behavior in the post by: - Using a new, random executable. Even echo $rand_int will work. Edit: What I mean here is generate your rand int beforehand and statically include it in your script. - Using a fresh filename too. Just throw a rand int at the end there. e.g. /tmp/test4329.sh I MITMd myself while rec…

The isn't specific to the article, but another place that can be interesting to look at system activity on Mac OS is the console.

I am using Ubuntu 20.04 on a Thinkpad X1 Extreme Gen2 and you would be surprised how "normal" it feels as a development machine. Sure there some little annoyances, the touchpad behaves a little worse than on windows, sound is a little worse. But the most important things, Keyboard and Screen are excellent. The system in general does not feel like the horror stories that people keep telling about linux on desktop(note…

Many of us who have been using Linux just fine on desktops and laptops for decades find those horror stories to be overstated...
