What’s inside new rMBP ?

Found a screenshot of new rMBP with amd card inside:

Device-id is 6821, looking at it’s closest brother 6820 –

It’s mobile variant of cape verde chip that’s found in radeon hd 7770.
640 shaders, 16 ROPs, 40 TMUs, 128-bit bus.

And, just x8 pcie ?

Well, x8 pcie 3.0 would be equal to x16 pcie 2.0, but why?

The cpu has total of 16 pcie 3.0 lanes, x8 to gpu, two of x4 to TB controllers?

gtx 750ti is much faster than hd7770, cosuming less power, if only apple would include gm107 into new rmbps…

If OSX 10.10 update fails for you…

With next message:

“This partition map modification would make a windows partition unbeatable”

It means that some Apple programmers are lazy dumbasses.

Here is how to fix it: you need to backup current mbr on your OSX drive, remove any partitions in mbr except the first one with type EE (so disk will look like pure gpt disk). Install osx update. Then restore mbr from backup. Then show middle finger to Apple (it’s not that hard to fix for lazy apple programmers)

you can do it with gptsync or with fdisk and dd.

It happens because of missing recovery volume. I miss recovery volume because I had to restore osx partition from TM backup. HFS+ isn’t that great and can be easily crashed with few resets.
P.S. it’s all for MAC, not HACK (even tho hacks ccan use that way too). Owners of genuine Macs have to mess with it. It’s shame !

New imacs…

M290X is radeon HD 7870 but at lower 900 mhz core clock. A bit slower than 780M you can find in current Imac.
and it comes with 2 gigs of vram, kidding?

M295X is some tonga chip, probably full tonga chip ( equal to 7970). Will be like one D700 of newMacPro.
4 gig vram here.

That’s too weak to play anything at 5K, they even will struggle at 2560×1440. Only for 1080p gaming.

SmartWatch typical everyday usecases

For those waiting for applewatch.

I’ve been using sony’s smartwatch 2 for a half year now. After initially playing a lot with it for few weeks I came to these typical usecases, asuming the phone is in the pocket:

1) read incoming sms/emails. Answering using a watch is JOKE, you will almost never do it, be it dictation, templates, smiles, or onscreen keyboard (like in latest samsung stuff), easier to pull phone off the pocket. wathes vibration help to do not miss any.

2) read notifications from apps.

3) see who is calling you, dismiss call if needed. you don’t want to press answer on watches because the other side will hear you pulling the phone out of pocket.

4) check time and weather on main screen.

5) control music (play, stop, next, etc)

That’s all, rest is just gimmicks you will play with for few weeks.

Not talking about some fitness tracking abilities. It’s just about average Joe.

Slow Radeons 7xxx+ on MacPro3,1

It’s known for a while that GCN radeons are low performers on 2008 MacPro using OSX 10.9

And the reason for this is…..


Apple fucked up some CPU power management resulting in videocard not running properly. plz fix.

Just remove AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext if you like to workaround it, speedstepping still works, cpu isn’t hot/cosuming a lot, still drops the clocks.


Efi bootloader for 32-bit efi macs and osx mavericks.

Hello. It’s a bit old, but still awesome news. An osx bootloader for old macs with 64-bit cpu but 32-bit efi (like macpro 1,1/2,1). Can boot osx mavericks, supports efi in osx, so nvram, firevault and other things depending on efi runtime calls will work.

Check it out here


OSX 10.9.1

cat /System/Library/Extensions/AppleKextExcludeList.kext/Contents/Info.plist | grep netkas

32-bit boot.efi actualy can boot 64-bit kernel

Looks over here – They are patching 32-bit boot.efi to make it loading 64-bit kernel. Obviously such functionality cant be added if it werent present at all. So they just disable the check/lock preventing it. ML on original macpro.

So, greedy Apple, can boot 64-bit kernel on all their macs with 64-bit cpu but decides not to!

Moiuntain Lion Sources released

So, Apple released sources of some components of mountain lion, like xnu kernel.

Just for fun, I’ve built 32-bit xnu kernel –

Running openCL on gtx670

more here

long story short – by default opencl doesnt work on gk104 but works on apple’s gk107 from new mbps. Now it works on gk104 (gtx670-gtx690)

Update: obviously ML drivers are much better (still need a patch so)
