In Topic: 10.6.3 Released !

29 March 2010 - 04:55 PM

You're seeing the difference between the delta and combo updates. In your case, OS X has detected that you only need the 10.6.2 - 10.6.3 update, not the complete 10.6 - 10.6.3.

Sleepenabler will always panic if it isn't matched to the kernel version, so it would appear that 10.6.3 includes a new kernel.

EDIT: yep. 10.3 kernel. There also doesn't appear to be a performance increase in OpenGL scores. At least, not on my Macbook. I'll have to test that out on the desktop hack tonight.

I'd also like a Macbook Pro. Funny, because before I started playing with hacks, I had no interest in Apple hardware.


Once that OS X bug bites, it becomes very tempting to see how well it works when it's running on the intended hardware platform. The complete integration makes the already strong OS X unbeatable, IMHO.

I've only had the Macbook Pro a few days, but I'm already convinced that it's the computer for me. I just wish that Apple would ship a high-resolution display for the 13-inch models. After working with the Dell's excellent high-resolution screen, moving back to 1280x800 feels a bit constrained. I'm already getting used to it, but the extra pixels made a huge difference in productivty. I just wasn't willing to move up to the 15 for portability reasons.

Yes, I've poured over every relevant thread I found, and there is actually powerfully little unique information out there. I've tried lots of patches with different boot loaders and kernel flags. Basically, I haven't found anything very earthquaking other than what SA22C posted earlier. I still regard him as our resident DSDT expert on these machines, as he was first here and I think has the best understanding of the process. I've tried lots of other things for the D630 with very marginal results. One thing additional that I did do was for GMA950, and I ripped out vid devices other than LCD to enable using stock kexts without black screen or artifacts. It's a sledgehammer approach to the problem, and creates other problems when trying to dock or use additional displays, but it sort of works and provides at least display sleep but not full sleep.

I'll be updating page one with some experimental stuff later today or tomorrow.

In order to improve on the info that we have, I am afraid we're going to have to download a 700 page manual and make our own solutions. From what I can tell, SA22C did a pretty damn good job of summarizing the available stuff that applies and actually works best for our machines.


I'm no expert, but I'm glad that I was able to help out by collating the relevant info so that it was more easily accessible. You're right on that the only way forward from here is actually studying the ACPI specification and doing some honest-to-god coding. It's a tough slog, but there you are.

For my own part, I'm not likely to be pursuing this DSDT stuff much further on the D620 because as of yesterday, my primary computer is a MacBook Pro. I'll still be running OS X on my desktop computer, but it's been nailed down in terms of DSDT patches since the override became available last year.

I'll probably still follow this thread out of interest's sake. Best of luck to all of you and thanks to leppy for all the hard work! :thumbsup_anim:

I usually stay plugged in because my batteries are all old 6-cell numbers and I get less than an hour even in Windows. Without a properly patched DSDT - (both P and C states), it's unlikely we'll get great battery times. That's tricky DSDT patching, and I am still struggling getting basic functionality to work. Speedstep has to work so the CPU can idle when demand is low, which should be the majority of the time.


Well, I get between 3 and 4 hours on an extended battery with my D620. That's typically at half to 3/4 brightness and surfing the net/futzing in Terminal. On the Windows side, that battery is good for about 4-5 hours, so we are seeing a reduction due to inoperative C-States.

In Topic: Dual Core Timing Issue?

18 February 2010 - 08:52 PM

Okay so just read about this, which causes the entire computer to judder causing noticable things such as mouse lag etc

Ive just installed a fresh Snow Leopard, and booting using myHack with no custom Kexts, completely from scratch. The installation was perfect, no mouse problems of any sorts.. however now I boot up into Snow Leopard I am getting this problem heavily.

I can't find out how to just "cpus=1" because its a graphical boot loader, but besides I'd like to actually use both my cores (Core 2 Duo 2.16Ghz). What do I need to do to fix this problem? Thanks.


Check it out: VoodooTSCSync

That .kext should allow you to use both cores without issue. It works great on my Dell D620.
