I have noticed that as of 2013 with the arrival of Ivy Bridge, there is essentially no laptop with WiFi working out of the box. They all use either Intel Centrino cards, or modern Broadcom or Atheros cards which are not supported by OS X.

Apple hasn't updated their wlan cards in quite a while so we're stuck with drivers that only support the ancient AR9285 and some older BCM chips.

To make matters worse, some OEMs like LENOVO and HP add whitelist to their BIOS to prevent the wlan cards from being replaced by the end user. Repulsive behavior from those companies. Other OEMs such as Dell, Toshiba and Samsung don't have such whitelists.

Rumors have it that Apple will be including new Broadcom wlan cards based on the 802.11ac standard in the near future, most probably with the introduction of Haswell.
That means we might soon see updated drivers for BCM 802.11ac wlan chips and possibly even some backward compatibility current-gen unsupported 802.11n chips (such as 4365, 4313... etc)

I doubt any Centrino or newer Atheros chipset would ever get official support from Apple.

Hopefully some talented dev with the need time and skills can port linux drivers for those cards, though I was told that it would be a major challenge due to encryption and lack of code samples by Apple.

I guess we'll just have to wait and see.

AS of 10.8.3, the stock Apple kexts include the dev-id of the Ivy Bridge HD2500 IGPU.
Edit: This seems to work with DVI and HDMI only. No VGA.

1- Enable Chameleon's Graphics Enabler.

2- Set smbios to Macmini6,1 or 6,2

3- Inject the following EFI device properties.
ig-platform-id: 01660003, FB Memory: 64MB, Pipes: 2, Ports: 2, FBMem: 2

On rebooting, the graphics card will be detected as HD4000, and you'll have full resolution and QE/CI

Ever since updating from 10.6.8 to 10.8.2, I've had a nasty problem with file sharing between my Android (ES File Explorer) and Mac OS.
I could no longer authenticate into my Mac using SMB to access different "volumes". The only way was to add the entire volume I need as a public folder which in my case is totally unacceptable.
I needed password protected access to the volumes.


How I got around it?
Easy. Using SFTP:

I went into System Preferences -> Sharing -> marked "allow remote login".

Next on my android tablet, I opened es file explorer, selected SFTP, typed my IP, user name and password and BOOM. I have full access to all mounted volumes again. And I believe its even faster than SMB.

What happend between Snow Leopard and Lion/Mountain Lion?
Well, I believe that Apple ran into a licensing issue with SAMBA so they had to trim down support for SMB and replace it with AFP. Only AFP can authenticate and access password protected volumes.
This problem appears to be plaguing OS X Lion/ML users everywhere. Most people suggest reinstalling the old SAMBA which can be a pain in the @ss. I believe this solution is much more elegant.

I hope this comes in handy to someone like me who depended on SAMBA to share files between android and Mac OS.

The Bad:
As of Mac OS X 10.8 Mountain Lion, Apple has completely removed support for 32-bit kernel extensions and the new kernel no longer supports booting in 32-bit mode. As you probably know by know, most GMA950 drivers that were provided by Apple were 32-bit extensions and therefore will no longer work with OS 10.8!

The Good:
Apple has included 64-bit drivers for GMA950 in the OS X 10.6.2 update. These drivers can be used to provide partial support for GMA950 under OS 10.8

The Ugly:
The drivers are painfully slow especially at higher resolutions. System animations lag, full screen videos are almost unwatchable, flash videos are not working properly.

The "partial" fix:
Use the 10.6.2 extensions attached below to get resolution changing and QE/CI. Install using kext wizard or whatever other utility you like. You still need DSDT or EFI string injection.

The real fix:
Well... I think its time for an upgrade. A cheap nVidia 8400GS or ATI Radeon HD5450 will get the job done perfectly if you have a desktop PC. Laptop users however, are out of luck this time.

Edit: I just got a GT210 and it works perfectly well with GE=Yes.
