NetBoot PowerPC, Intel Macs from Mavericks Server

macOS 11 Comments

As part of some maintenance here, I did a little research as to how to set up NetBoot for various different Macs. For this piece, interchange 'NetBoot' with 'NetInstall' if you're being pedantic - I'm NetBooting the install disc for a particular OS. NetBooting a full install should also be possible using the same techniques.

Mavericks Server (an app free to all developers) has a built-in NetBoot (NetInstall) server GUI, but it only supports a handful of modern versions of OS X. Thankfully, if you follow the instructions in the bootpd manpage you can manually build NetBoot images supporting both PowerPC and Intel Macs going back to OS X v10.2.

Because we can.

Improving the state of 4K display support under OS X

macOS 26 Comments

In my Mac Pro review I lamented the state of 4K display support under OS X 10.9.0. In my conclusion I wrote: "4K display compatibility under OS X is still a bit like the wild west at this point". Compatibility was pretty much only guaranteed with the ASUS/Sharp 4K displays if you cared about having a refresh rate higher than 30Hz. Even if you had the right monitor, the only really usable resolution was 3840 x 2160 - which ends up making text and UI elements a bit too small for some users. Absent were the wonderful scaling resolutions that Apple introduced with its MacBook Pro with Retina Display. Well it looks like that won't be the case for long, last night I got reports (thanks Mike!) that the latest developer build of OS X 10.9.3 includes expanded support for 4K displays, 4K/60Hz support for rMBPs and scaled resolutions below 4K.

So, OS X is essentially the only desktop operating system with proper HiDPI support, right?

Porting XNU to ARMv7-A

macOS 3 Comments

As you are all probably aware of (I hope), I maintain an open-source port of the XNU (iPhone OS/Mac OS X) kernel to ARMv7-A (soon AArch64 and ARMv6/v5!) platforms. The kernel is very bare in its implementation and needs a lot of work. Work seems to also not be put into the proper areas, so I made this article to rectify that issue. Simple enough, I hope.

Very interesting (via @stroughtonsmith).

OS X 10.9 Mavericks: the Ars Technica review

macOS 46 Comments

Apple has released OS X 10.9 Mavericks - for free - so it's that time again: John Siracusa's excellent OS X review.

According to Apple, Mavericks has a dual focus. Its first and most important goal is to extend battery life and improve responsiveness. Secondarily, Mavericks aims to add functionality that will appeal to "power users" (Apple's words), a group that may be feeling neglected after enduring two releases of OS X playing iOS dress-up.

Is that enough for Mavericks to live up to its major-release version number and to kick off the next phase of OS X's life? Let's find out.

OS X 10.9 Mavericks preview

macOS 5 Comments
"This is still early, early days for OS X 10.9, and Mavericks will likely change and shift much more before it's released this fall. It's clearly not going to be the total aesthetic overhaul iOS 7 is, though, and that's okay. It’s a simple, familiar operating system, even less of a change than Mountain Lion, just with nips and tucks and a whole lot fewer sheets of weirdly torn paper. It has its bugs, sure, but it's also corrected a number of bugs that somehow made it into the final version of Mountain Lion, and even at this early stage is impressively stable and fast. It's gotten rid of a lot of the design issues that plagued many Mountain Lion apps (except for Game Center, which is still hideous), in favor of a cleaner, softer look that is far easier on the eyes." Hard to complain, really.

OS X 10.9 to include power-user enhancements?

macOS 75 Comments
"OS X 10.9, which is internally codenamed 'Cabernet', will focus on various 'power-user' enhancements and take core features from iOS, according to our sources. Unlike operating system updates such as OS X Leopard and OS X Lion, OS X 10.9 will likely not be an overhauled approach to how the operating system feels and functions." Features for power users and features from iOS? Seems like an oxymoron. Still, if they manage to finally fix the Finder and Spaces, I'll be happy.

Quicksilver moves out of beta

macOS 4 Comments
Via Ars Technica: "After almost 10 years of testing, Quicksilver lays the beta tag to rest (if the lack of an eszett brings a tear to your eye, you can always reminisce by hitting option+S on your keyboard). What does this release mean? It means more than just a change in the version numbering system - it signifies a maturity of Quicksilver and a sign of what's to come." Quicksilver is fantastic for those of us for whom command+space and the dock combined is not enough. While I personally don't use Quicksilver (I use Spotlight through command+space to launch applications), I know of quite a few Mac users who swear by it.

Getting rid of the Finder’s ‘Open With’ duplicates

macOS 17 Comments
"This is the problem: You want to open a file using something other than the default application. You right-click its icon in the Finder, choose Open With, and a submenu pops up with an absurd number of duplicate entries." This is so annoying. Dr. Dang made a little addition to .bashrc so you can fix it with a single command. Now it's up to Apple to actually fix the problem (via Daring Fireball).

From Linux to OS X: 1 year later

macOS 82 Comments
"A little more than an year ago I wrote my rant post The Linux Desktop Experience is Killing Linux on the Desktop and for the first time in 8 years I wasn't a desktop Linux user anymore. I spent about a month wrestling with Windows 7, but let's face it - Windows is ill suited for professional Ruby programmers like me (and it's ill suited for most programmers, except maybe Java & .Net I guess). Anyways, it was never my intention to stick with Windows - I was just doing my Mac due diligence. Now with 1+ year of OSX usage I'd like to share a few things about my experience thus far with you."

OS X Mountain Lion: data loss via ‘Save As’

macOS 44 Comments
How this passed through Apple's Mountain Lion testing is beyond me. "If one edits a document, then chooses Save As, then BOTH the edited original document and the copy are saved, thus not only saving a new copy, but silently saving the original with the same changes, thus overwriting the original." Just goes to show: do not mess with my ability to save my stuff. There is no one-size-fits-all for this kind of delicate stuff.

Graphics improvements give Mountain Lion that speedy feeling

macOS 19 Comments
"Has Mountain Lion been feeling faster for you compared to Lion on the same machine? It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

The Mac App Store’s future of irrelevance

macOS 20 Comments
In agreement with Marco Arment? I shall quickly venture outside and inform myself of the possibility of catching a fleeting glimpse of an avian sus scrofa domesticus. "The Mac App Store is in significant danger of becoming an irrelevant, low-traffic flea market where buyers rarely venture for serious purchases. And I bet that's not what Apple had in mind at all." There's an issue with the Mac App Store: Apple runs the danger of chasing most serious applications away from the store. While I would personally consider this to be a big win for computing, I'm sure Apple doesn't exactly see it that way.
