    GTX 970: Poor performance, VRAM not reported accurately

    So I just updated to Sierra, and I had some trouble getting the Web Drivers working. I've succeeded, and everything appears normal––I have graphics acceleration and the UI is snappy––but if I try to play a game problems become apparent. I can't get an average FPS above 25 or so. I can't confirm...

    GTX 970 - slowed down, then fixed itself. Would like to know what happened.

    So this post is somewhat academic because the problem seems to have fixed itself, but I would like to know what happened in case it happens again. Played Alien: Isolation, and noticed the FPS wasn't that great for my card. Around 40 FPS usually. I thought, OK, whatever, maybe it's a bad port...

    PIONEER BD-RW: "disk drive is unsupported (error code 0x80020025)."

    I have a PIONEER BDR-208D which worked fine in Yosemite/Chimera. In El Cap/Clover, I get a "disk drive is unsupported" error when I try to eject the disk. It'll load and play just fine, though. Any ideas on how to troubleshoot this?

    Clover takes a long time to load

    I've finally migrated to Clover and gotten El Cap working on my P55M-UD2. Everything works, but the one thing I'd like to try to fix is that it hangs at a black screen with a _ before finally loading the boot loader for about 20 seconds or so. Any way of fixing this?

    Boot from SSD- boot0af error

    I have a legacy BIOS. After I installed fresh, install went fine, and I installed my web drivers and Clover on the SSD. However, when I try to boot, I get a boot0af error. Any ideas? The drive is a 960GB Crucial M500. Thanks.

    El Cap drive not appearing in clover after install

    After installation, the computer rebooted and I booted from the USB. A recovery partition was there, but not my El Cap disk. If I reboot without the drive, chimera will load but it'll restart when it gets to the Apple loading screen. Did I screw up by not getting rid of Chimera first? How can I...

    OS X 10.11 - rootless

    Hope this doesn't throw a wrench in things. From 9to5Mac: "Sources within Apple are particularly enthusiastic about a new security system called Rootless, which is being described internally as a “huge,” kernel-level feature for both OS X and iOS. To prevent malware, increase the safety of...

    Installed a 970 / security update, now hangs at apple logo.

    Hi, I installed a GTX 970 today and I'm rather stuck. I used nv_disable to boot, added the nv_drv=1, and installed the Web Drivers. I had to use pacifist to do it. The prefpane did not work at this point. Then I installed Security update 003 (probably a dumb idea) with a restart. Now on...

    P55M-UD2 Sleep issues

    I was hoping Yosemite would magically resolve this, but alas. I have this bizarre sleep issue where the computer will go to sleep fine, but it will randomly wake up again, although the display doesn't come on. Sometimes it will go back to sleep again on its own, but it will inevitably wake up...

    Yosemite, no audio

    No luck with sound on my P55M-UD2. I used multibeast to select my realtek ALC888b legacy driver, but it did not work. Anyone else having problems?

    Install successful, but can't find mach_kernel

    Installed successfully, then upgraded to Chameleon 4.0. I get a "can't find mach_kernel" error, however, when I try to boot without Unibeast. I should note that I have a fusion drive, if that's relevant.

    Misc. bugs

    Just updated to Mavericks, and while the new version of Multibeast is quite nice in terms of features (the config file idea is genius) I have noticed quite a few problems. -Had to launch the app via a terminal, due to the issue on the main page (If apple did indeed revoke the cert. of the...

    P55M-UD2 No sound after 10.8.5 combo

    Hi, I updated to 10.8.5 and I'm having trouble getting sound back. I chose "ALC 888b Current," (w/ DSDT) with no luck. Should I be selecting something else? Thanks

    Unibeast Installer Not Working

    Hi, I'm trying to make a ML USB drive. I've followed the steps to the letter, but when I try to run the installer it takes about 20 seconds and there are only 3 folders in /USB, no ML. Any ideas? Thanks. My ML Install app is in /Applications.

    Bluetooth woes: targus, belkin mini

    Hi there. I'm having a frustrating time getting Bluetooth to work. First I bought a Targus ACB10US and that worked half the time, but sometimes on restart or waking from sleep it would go dead. Then I got a Belkin Mini (F8T016) which doesn't work at all. The Bluetooth menu item says it's on, but...

    Changing the bootscreen resolution

    Hi there, I'm trying to change the bootscreen to my native resolution. The added lines to my boot.plist file in /Extras isn't doing anything. Thanks for any help. This is what the file looks like: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"...

    Weird Liteon Bluray drive issue

    I've begun noticing a bizarre optical drive issue. I have a lite on iHos 104 Bluray drive which works flawlessly in Windows. In OS X, sometimes it doesn't appear in the Finder. It will be detected in System Profiler, but it will only display a limited amount of info about the drive. I have used...

    P55M-UD2: Blu-Ray not recognized, sound, esata

    Hi there. Just built my first PC and I'm having some issues. So far, my OS X install is going smoother than my Windows install. (It can't find DVD drivers when I install, I could use help on that one too if you have any ideas!) Here are my remaining issues, in order of importance: 1. I am...
