    OS X OpenGL 4.1 Broken on NVidia for Almost 2 Years

    NVidia is normally a go-to choice for hackintoshing since it basically requires no configuration, unlike AMD and Intel with their various framebuffers. But what about the driver architecture that goes into the kexts we rely on, are the more complicated AMD/Intel ones better somehow...

    Handoff (Bluetooth Low Energy) Tester

    This is a quick command line tool which I think tests correctly for Handoff (Bluetooth Low Energy) support. So far I've only seen posts referring to the LMP version, which is unhelpful; the Link Manager Protocol version corresponds directly to the Bluetooth marketing version, and even then each...

    pbzx Stream Parser

    For anyone interested in pbzx streams, the following command line tool can unpack the xz frames from stdin, then echo to stdio for piping to `cpio` for unarchiving. Implemented in simple C: --edit On the eve of the (likely) release, I have updated the parser. When compiled with liblzma...

    A Real MacPro6,1

    I recently got access to an off-the-self MacPro6,1 with six cores and the D500, and took a look at the hardware. I was interested in the Thunderbolt and graphics, and what the Intel and other chipsets looked like. There are many different ways of looking at the information in the IORegistry, and...

    How to Make a Certificate Authority

    Trust For those who aren't versed in Public Key Cryptography and certificates in particular, the concept of Trust is twofold: users not only put their Trust in an organization like Verisign to certify the organizations they distribute their certificates to, but also to Trust the safety of the...

    AppleHWAccess: Random Memory Read/Write

    Those who took a closer look at Mavericks may have noticed many new kexts, this article focuses on one particularly novel one: AppleHWAccess.

    What's New in Kext Development

    What's New As many of you already know, OS X 10.9 Mavericks has added a new security feature [PDF] which will affect all hackintoshers: signed kernel extensions enforced by the system. Apple has recommended [PDF] that all kernel extension developers join the Mac Development Program and request...

    Latest Haswell (LGA1150) Motherboard Info

    So to help others out I've done a scrape of NewEgg's current list of 1150 motherboards for Haswell. This table is only a subset of the data, but hopefully the most useful. I will try to keep this list updated, but if you notice an error, please contact NewEgg _first_, it's their information...

    Apple's OpenGL+OpenCL Test App: Galaxies

    Apple includes an example app with Xcode's documentation called Galaxies, which performs an NBody simulation (many planets/stars' gravitational fields interacting) using OpenGL for placement and display, and OpenCL to calculate the forces acting on each object for each update. The result is a...

    Alternative to IORegistryExplorer: IOJones

    I've been annoyed by the lack of support Apple has provided for IORegistryExplorer since 3.0 came out, the biggest issue being asymmetric open/save (IORE can't open the files it saves). Beyond that, the binary plists it creates aren't human-readable because they're created using NSArchiver...

    Controlling Your Monitor with OSX: DDC Panel

    I've been trying to find a decent solution for DP/HDMI audio volume control in OSX, and while I understand Apple's reluctance to add another volume level to the "chain", my monitor has awful controls, and the difference between 0.8% and 0% is pretty high. To this end, I looked for and found a...

    DPCIManager 1.5 Open Beta

    So, I'd like to move this project along as well, though I don't have a solution for dmidecode on Clover yet. BIOS flashing still works, but it will not detect your motherboard until I find a way to make minimal edits to the normal package to support it. Otherwise, this build adds: "MSRDumper"...
