    macOS High Sierra Public Beta 5 is Now Available

    With Clover 4173 my installation went well, too. Before I had several issues: osinstall.mpkg missing, firmware update, etc. What does not work, though, is installing clover to the main hard drive - the installation fails. I'm on a legacy system. Can anybody tell me how to get clover installed?

    [SUCCESS] ThriftyMac - HP dc7900 - £100 - 10.9.4 Mavericks

    Hi. As I wrote in another thread on this forum, there is no need to use a DSDT with the DC7900. Everything works (except sleep) and the system even boots much faster without a DSDT than with the one found in this forum. Just edit the config.plist according to the settings found in the...

    DC7900 Build

Since that version is not eligible for an upgrade to macOS Sierra, I tried iMac8,1 (which matched my CPU). This, however, resulted in a blank screen with no...

    Hi. I'm on El Capitan 10.11.4. I would like to confirm that on my HIS 7750 (Device ID: 0x683f) editing the Info.plist in /System/Library/Extensions/AMDRadeonX4000.kext/Contents/ removes the black screen / artefacts issue. Cheers. Michael

    Hi. Can you please help me with my audio? I've got my DC7900 working properly with Clover (latest version, Yosemite 10.10.5), except audio. I got the onboard audio "working" (showing as output device) with Voodoo drivers. I got an old CMI8738 PCI card "working". I bought the...

    Gigabyte Radeon HD 6670

    I finally got my Gigabyte 6670 to work under Mountain Lion 10.8.2 without any modifications to the ATI6000Controller.kext. It is recognized as "AMD Radeon HD 6670 Series 1024 MB". It uses the Bulrushes Framebuffer. I use a HDMI cable on both sides. Here is what I did: 1) Created the thumb...
