When ethernet NICs are discussed there is always the issue mentioned that these (especially 10Gbit ones) run pretty hot and sufficient cooling is a must. But then on the other hand I see the current mac mini with 10Gbit option. How does that work? Do they use those devices in liquid nitrogen? :)...

Thinking about updating to Sonoma, but have to consider changing my current SMBIOS from 18,3 to 20,1 to be able to. Is 20,1 the most reasonable option for my system (z370, i7-9700K, RX580) or is something else more suitable? Wasn´t the T2 chip introduced somewhere on the way possibly causing...

AppleAHCIPort.kext used to cause issues with certain SATA controllers on previous versions of High Sierra. In 10.13.4 seems to be an updated version (329.50.20 iso 329), has anyone noticed improvements? (Would test myself, but have other issues preventing the update from .3 to .4 ...)

(I had this discussed in a different section (post installation), but as the problem seems to be a bootloader vs. specific display topic, this is my desperate effort to reach a clover expert.) Clover does not work correctly with a certain type of display, the Apple 23” Cinema Display (early...

I have two identical systems (except monitors) with 10.11.2, installed with UniBeast 6.1.1 and MultiBeast 8.0.1. One uses a Dell monitor with 2560x1440, the other an Apple Cinema Display with 1920x1200 resolution. In use are two identical HD5770. Both are using the exact same config.plist as...

The Unibeast usb stick creation was successful, in my case "legacy" without additional injection of any graphics kexts. Booting from the stick now reaches the clover screen for boot device selection. Booting verbose only without selecting any other option leads (repeatedly) to: P-State...

Looks like Multibeast Versions 7.x (or maybe even earlier) do not add an SSDT to the "Extra" folder anymore. Detected by chance due to different update methods of two identical machines from mavericks to yosemite. The first update was "on top of 10.9.x" via the app store. This machine did...

Like in 6.2.x audio doesn´t work anymore after sleep. (Updated were chimera, audio ALC889 and fake smc. System is GA Z68X-UD7-B3 with DSDT, 10.9.3)

After installing mavericks as a clean install on a SSD it still boots as fast as or even faster than mountain lion. But I notice a laggy display of application/document icons from the system SSD in the finder when navigating through folders. It´s just barely a second before they are displayed...

The OS X Supplemental Update is available via the AppStore or from here: https://support.apple.com/kb/DL1600 Should cause no issues as only a few extension are contained/modified: IOHIDFamily.kext IOPCIFamily.kext webcontentfilter.kext Installed without problems, but it does not...

Weird, without having made any changes I suddenly couldn´t boot. The system POSTed normally, recognizing all attached devices, but after "Loading Operating System" it stops where is normally would start chimera (no, I don´t mean the the boot:0 problem). This is true for all my attached devices...

After installation of mountain lion noticed stuttering when dragging windows (no, not window(tm)) across the desktop. But only on displays connected via display port, dvi connected displays worked smoothly. Even with two displays connected to one machine- one by display port, one by dvi - only...

Once in a while a observe an unintentional change of the mount point of one of my hard disk partitions. While the name of the partition as displayed in the finder remains the same, disk utility shows it changed, always in a manner like this: "/Volumes/PartitionName" changes into...

Having a couple of problems with 10.7.2 at the moment I have been stumbling across this issue: Whenever I repair permissions with disk utility on my main HD I always get the same status and repair report. (see attachment) ACL found but not expected on "private/var/root/Library"...

Hi, hope someone can help me and explain what is the cause of this panic. As on the screenshot: "(...) Faulting CPU: 0x6 Debugger called: <panic> Backtrace (CPU 6), Frame : Return Address (...)" Could this be a hardware problem or is it caused by how the OS handles the CPUs? I usually get...

Sorry folks, I remember someone reported an USB 3.0 PCI card working in his sandy bridge hack, but I can´t remember who it was nor were my last hours of forum search successful trying to find the post (must have been between spring and summer this year). As I´m tired of my VLI hub problems I´d...

The title says it all. I just get one autosleep after booting the hack. Not more. It will not fall asleep again automatically. Only after a reboot. Forced sleep works fine anytime. The system is 10.6.8 with F6 dsdt from the database. Same behaviour on 10.6.8 and lion with F7 and dsdt from...

I cannot sync my iPhone with iTunes as it always fails with a message like "cannot sync, sync process cannot be started". Also I noticed that the iSync app cannot be started manually. Strange though that on the same machine/system (regardless whether it´s booted as 10.6.7 or 10.6.8) other users...

I noticed several posts dealing with this issue. Maybe we can collect our workarounds here. They may be very different and depending on whatever is causing it. Let me start with what I had recently: Situation: "GPT boot error" displayed when trying to boot from a brand new formatted and...

Just wondering, apart from the wiki information about this topic, any suggestions what would be the most reasonable system definition to be used on the actual sandy bridge boards? Beyond pure cosmetical issues in system profiler: What are the effects of the new iMac and MBP descriptions on...
