Apple upgraded the Mac Pro in 2010 with Westmere Xeon CPUs, including a dual six-core option that can power through multithreaded workflows with aplomb. But what if you don't want to shell out all that money for a new Mac Pro? A clever hacker has discovered a firmware hack to effectively transform 2009 vintage Mac Pros into 2010 Mac Pros, including compatibility with Westmere CPUs, faster RAM, and audio output via Mini DisplayPorts.
A member of the forums on netkas.org—where lots of hackintoshers and system tweakers exchange tips—discovered the mechanism Apple uses to install EFI firmware updates. By exploiting that mechanism, a user named 'MacEFIRom' was able to develop scripts to force older, 2009 Mac Pros to accept a firmware update intended for the 2010 Mac Pros. That firmware enables a 2009 Mac Pro to act and operate just like the 2010 Mac Pro.
The firmware enables three main features for 2009 Mac Pro users. Perhaps of primary interest is that users will be able to install 32nm Westmere Xeons, including six-core variants used in the high-end 2010 Mac Pro, into their older machine. Single-socket machines can use W-series CPUs, while dual-socket machines will need dual-QPI enabled chips including the E5600 and X5600-series chips. (A source who applied the firmware update told Ars that Westmere CPUs are identified with 'B1' stepping in the identification code.)
- Mac OS X is not open in any sense of the word (open-source or open to all hardware), it’s “open” to all ISVs who can compile a dmg but that’s not a high bar to clear, and the “UNIX layer beneath” is useless as far as openness is concerned. TiVo has a “UNIX layer beneath”. The PS3 has a “UNIX layer beneath”.
- Apple responsible for 14% of NYC crime Jealous people pour liquid into Mac's keyboard or try walk off with the machine. Ripping iOS devices out of people's hands is common. Police warn people to not to use their Apple devices in the open. Mac's have been getting malware.
- I have a macbook pro 15″ (late 2011) running OS Sierra with 128GB SSD in the main bay and a 1TB Toshiba MQ01ABD100 HDD Sata II (3Gb/s) in the optical bay. Both are formated as MAC OS Extended (Journaled).
- Thats my laptop, is it better than a mac, my friend got a mac and all he wants to do wit it is play games such as wow and warcraft and swg and all these huge like over 12g games, and i told him to get a pc its better for gaming and hes like noo ur just jealous. So im trying to prove a point wats a better laptop for teenage to download music.
Even if you didn't plan to upgrade the CPU, though, there are other benefits. Some Nehalem CPUs can support 1333MHz DRAM speeds, but are limited to 1066MHz on the older Mac Pros. The firmware update will enable the full 1333MHz speed if you have a CPU and RAM combo that can support it. And, the updated firmware will channel audio signals through the Mini DisplayPorts on installed GPUs, making it easier to use with HDMI displays.

AdvertisementThe firmware trick works because Nehalem and Westmere Xeons use same chipsets and sockets. As we noted in our review of the dodeca-core 2010 Mac Pro, the internals are no different form that of the octo-core 2009 Mac Pro we reviewed in 2009. Apple seems to have merely tweaked the firmware and offered new CPU options for 2010.
While several users have applied the firmware hack with success, there are a few caveats to note if you plan to do it yourself. Apple does not consider the CPU in any of its machines to be a user-serviceable part; swapping it will void AppleCare, and so will applying an unsupported firmware update. The tool that MacEFIRom released allows users to revert an upgraded 2009 Mac Pro to the original firmware, so it's possible to undo the hack before taking it in for service. However, some refurbished 2009 Mac Pros have a special firmware revision that is not publicly available—if you have one of these machines, you won't be able to revert back to stock.
Also, since your 2009 Mac Pro thinks it is a 2010 Mac Pro (it will report itself as a MacPro5,1 in System Profiler), your original system install discs will no longer work. You'll need 2010 Mac Pro restore discs if something catastrophic happens and you need to reinstall Mac OS X.
Finally, newer Mac Pros have a newer version of the System Management Control firmware. The SMC controls (among other things) the cooling fans, and the newer version in 2010 Mac Pros can make some GPUs run cooler. However, the older firmware for the 2009 Mac Pros doesn't appear to adversely affect the operation of the machine in any way.

Apple is launching a new Mac OS X 10.8 aka ‘Mountain Lion’ this summer and it promises to import features from Apple’s iOS. Why should mobile have all the fun right? Historically, Apple launched all major Mac OS releases at its annual developer conference. This time, they changed the game showing it off 9 months before it hits the market which means Apple and developers have less time to integrate new features and work out bugs.
Here are 5 intriguing facts about Apple’s New Mac OS X ‘Mountain Lion’ you need to know:
1. Developers get to preview Mountain Lion today! Looking for another reason to become an Apple developer? We have just what you need: Mountain Lion is being released as a preview to all developers today. The commercial release will be released sometime this summer through Apple’s Mac App Store.
2. Mountain Lion will include popular iPod and iPad features. As Apple has previously done with Lion, the new Mac OS X 10.8 will come with many of the most popular features from the iPad and iPhone. Their intention is to make Mac computers more useful and approachable to those who got an iOS device (such as an iPod, iPad or iPhone) in the past. Their hoping Macs will become as essential as other iDevices.
3. OS X and iOS are still different. Not at all. Apple is working on creating a neighborhood of sorts where subtle differences require users to have both the OS X and iOS so that everything ties together to feel more unified. They will not be merging the two systems.

4. Apple is sharing 10 features that will launch with the new Mac OS X 10.8 ‘Mountain Lion”. Apple is giving away all its secrets but they are sharing 10 features that will come with the new OS. These include iMessage (check out our previous post, 3 Ways to Reach iMessage Enlightenment, for more tips on iMessages!), Reminders, Notes, Share Sheets, AirPlay Mirroring, GateKeeper and an assortment of localizations to OS X aimed at Chinese users including system-wide ties-ins to search engines and content sharing sites.

5. Siri is missing. Apple hasn’t included Siri in it’s 10 new features that come with the new Mac OS X ‘Mountain Lion”. There’s still time to add it in before the summer release, but so far it hasn’t made the cut. Some think desktop computers don’t need Siri at all. What do you think?

Overall, Apple’s New Mac OS X ‘Mountain Lion’ is huge news for Apple fans all across the globe. This new release promises to impress with 10+ new features including iMessages, Reminders, Notifications and more. We’re jealous of the developers who get to start beta testing today.
