I don't understand why in Clover is GraphicsEnabler always yes in bothtwo possible configurations (UEFI or Legacy) that are offered. I have a GTX 760 and I have right now GraphicsEnabler=no and IGPEnabler=no. Except some freezes from time to time (they started with 10.10.x) I get no other issue...

Sound disappeared since this security update Edit: I had to mute/unmute, just regulating the volume up and down was not enough.

I solved my problem with "-np-zp" kernel flag at boot time (or in com.apple.boot.plist).

Is there a way to revert to the previous kernel (10.10.2 without SU-003) without reinstalling?

Which keyword should I look for?

Since the update I am experiencing again freezes almost continuously.

With my other monitor I get no freeze at all. And now that I switched back to Apple graphic drivers I also get no freeze at all (at all = once a week, as usual, not one every 5 minutes like with Nvidia Web drivers + UP2414Q).

I have the same issue with NVidia drivers on 10.10.2 on GTX 760, I switched back to Apple drivers because of the fan issue.

There is no way to go back except reinstalling from scratch. But really, do you care so much about 60Hz? I personally found NO issues at all for office use, only games and (to a lesser degree) films/videos would make use of them. I also don't like to have something and not to use it to...

I won't sacrifice updates and security updates for 60Hz, when the difference is almost non-existent: for office use 30 Hz are perfectly fine and you don't even notice them, unless you look for them. You notice them more if you play videos, the 24fps is jumpy when played at 30Hz, and almost not...

It is ok to boot without kernel cache once, but after it boots ok, you should reenable it, to speed up the booting: since the cache at that point is made on the kext of your WORKING setup, no need to remake it every time. Usually, as proof, the -f is needed to get a successful boot, but then...

I know, but with Apple driver the core/RAM frequency never goes down to idle, it stays at 1.00/6.00 GHz after a while (or at least it was like this in Mavericks). Also, I think the web drivers are required for 4K 60Hz in MST mode.

I switched definitely to MacMini6,2, I switched back to Apple graphic drivers, I also remade SSDT with the latest script. Freeze are gone, until now at least. NVidia drivers (on 10.10.2) were the culprit. On 10.10.3 I will try them again, I still hope to get 60Hz.

In my case, with a GTX 760 and a GA-Z87MX-D3H, the freeze were gone (4x8GB) and they came back when I switched to a Dell UP2414Q (4K, 30Hz). Switching back from Web drivers to Apple drivers solved the problem. Of course, the idling of the video card is lost, it stays at 1GHz/6GHz, but the fan...

I write it here because I have this same configuration (excluding the processor) and someone may find it useful: Initially I had some freeze issues, seen often also in other setups...

It is a bug of that driver, so yes, disabling TSO will work indefinitely. I never had any hang after that change. As I wrote, remember to apply it at boot time by modifying the init file.

Here the topic is "fake" Macs, built with PC components. You have a REAL Mac, it's a different situation :)

Hello, I am using the UP2414Q on my Hackintosh 10.10.2, Nvidia drivers latest revision, DP connection, MacMini6,2 in Chameleon.plist. I wasn't able to get 60Hz but I think it depends on 10.10.2. The computer is extremely unstable, freezing very often, also less than one minute after boot...
