Apple releases Boot Camp 3.1, includes Windows 7 support

Apple has released Boot Camp 3.1 which now includes Windows 7 support.

The new firmware updates and Boot Camp is designed for both 32-bit or 64-bit versions of Windows 7. Boot Camp 3.1 adds support for Windows 7 Home Premium, Professional and Ultimate editions. Apple's wireless keyboard and Magic Mouse are also now supported. The update also fixes issues with the Apple trackpad and disables the red digital audio port LED on laptop computers when not in use.

Alongside the Boot Camp update Apple also made a iMac firmware upgrade available. Apple originally planned to release Boot Camp 3.1 before the end of 2009 but due to extra testing the update was delayed until today.

All Intel based Macs are supported except the following:

  • iMac (17-inch, Early 2006)
  • iMac (17-inch, Late 2006)iMac (20-inch, Early 2006)
  • iMac (20-inch, Late 2006)
  • MacBook Pro (15-inch, Early 2006)
  • MacBook Pro (17-inch, Late 2006)
  • MacBook Pro (15-inch, Late 2006)
  • MacBook Pro (17-inch, Early 2006)
  • Mac Pro (Mid 2006, Intel Xeon Dual-core 2.66GHz or 3GHz)

Better late than never I guess.

That being said, I've had 7 running on BootCamp for months with only a few driver issues. Hopefully this update will take care of that.

The fact that Macs can run Windows is among Apple's top reasons to "switch" to a Mac and is partially responsible for Apple's increase in sales over the past few years.

REMEMBER: Users of the Late '09 iMacs (21.5" and 27") need special drivers before they install Windows 7! [Link: http://support.apple.com/kb/DL995 ]

I wonder why the Mac icon is in colour and the Windows icon is in grayscale. That seems a bit petty of Apple...

Maybe not to infringe on the Windows logo?

ok.. the so expected bootcamp 3.1 that should support win 7 is a piece of crap! The only thing fixed is that now, the bootcamp.exe process does not generate DPC latency. And there were workarrounds for that.

Most important things not fixed:
Power management: - Still no Adaptive Display Brightness Support
- Still not gpu temperature measured so that the cooler works as it should (macbooks run hot on windows)
Audio: - The audio is really low compared to OS X (on realtek HD audio).

This is my diag from a late 2009 13" aluminum Macbook.

If someone knows how to fix (or has any workarround) for the two problems from above, please, let me know.

I'm having these problems with Boot Camp 3.1 on either my iMac or my MacBook Pro :
- Wifi connections. Urgh. I'm losing it every minute. It started doing this today, even before Boot Camp 3.1. So it has to be Windows, and not Boot Camp.
- Need to triple-finger tap on my TrackPad on the taskbar to right click.
- When I'm using a smaller-than-native resolution on my iMac, instead of taking the whole screen, it shrinks the picture and centers it in the monitor O_O It didn't do that with 3.1 after I installed it, but it did that like an hour after I played around with it. I have no clue what to do.
- Windows 7 drains the battery like a bitch. I can hold it for 7 hours under OS X, but like 2 hours in Windows 7. I don't know if it's Windows or Boot Camp lol... but Windows surely plays a huge role in this.

What it fixed :
- Totally corrupted ATI graphics
- Red light emitted from the audio output
- I can now plug my Z5500 speaker set (just discovered how today - could I do it before by changing the source? I don't know)

So yeah, recommended update, but there's room for ameliorations ...

or...seeing as windows hasn't changed...at all...it's either mac's HARDWARE or DRIVERS. >>

Windows 7 was tested to have ~95% of the battery life of mac when setup properly wasn't it? Can't imagine this getting WORSE. And other laptops get BETTER power useage for the same battery capacity under windows then mac does... so I'm guessing it's either drivers or firmware that's causing the 7 battery life issue. my eeemahine pulls 8+ hour battery life all the time.

I honestly don't think Apple is trying very hard to support Windows 7, tbh. Look how long it even took to get drivers out? Proper hardware support for Windows 7 isn't high on their agenda.

It sucks that people are still having problems. I haven't tested the new drivers much. I just need to use this one program in Windows every once in awhile, so this isn't as much of a let down to me as it is to others. But still, shiesh, it isn't like they have THAT much hardware, they should put more effort into supporting it properly.

I can confirm that Windows 7 does work on an "unsupported" Intel iMac. Have 32bit running perfectly on mine using the drivers from the 10.6 DVD. :)

Finally got 7 installed on my new iMac 27. upgraded to this. No real performance differences or anything... considering this was likely a minor code change, it makes me wonder why it took them so long.

Downloading the Boot Camp upgrade at this moment, the 64 bit is 275 MB, and 32 bit is 381 MB.

Here is a question for those in the know: will the 10.6.3 upgrade have Boot Camp 3.1 built in? Thanks ahead of time for the answer.

... Shouldn't the 64-bit be bigger? Even just a little?

I'm pretty upset my Macbook Pro that's less then 3 years old doesn't support Windows 7. I guess that's Apple for you though!

Kinda sad that Microsoft is loyal enough to its users to support an age-old operating system, isn't it?

How is that sad?

I can't get it to install on Windows 7 64-bit. I've downloaded the package, but when I double-click on it I get a UAC prompt, I say continue, and then....nothing happens?

I'm running XP in my Boot Camp but can't hurt to update anyway.

Being an OS X user, you will truly like Win7 better than XP, our Mac techs don't mind Win7 so much, but scream when they have to use an XP machine.

i.e. If you get the chance or can afford Win7, just do it.

I only need to boot into Windows occasionally so XP works fine for my needs in Boot Camp (I have 7 on my PC). Plus I don't think Aero would be a great experence on a GMA950. Or am I wrong about that?

Cool, I might get around to playing with Boot Camp on my Mac mini, but not till after I upgraded it first :P (160Gb HDD is a bit cramped just for OSX alone, let alone dual booting on it)

Why not us an external drive for music, pictures, etc., and use just the 160 HDD for your OS along with applications, and Boot Camp.

I could do that but have no spare external drives at the moment. I plan to upgrade the Mac mini regaurdless anyway as I want more RAM so figured I'd up the HDD as well while I was at it, seems a little counter productive to buy another external drive to play with Boot Camp now when I can just wait a bit longer till I upgrade the HDD [and RAM], if that makes sense.

Not sure what problems people have been having with Boot Camp 3.0, albeit so far (knock on wood) I haven't notice any problems running Win 7 64 ultimate thus far. However, as everyone else I will up date before the day is over. Running Boot Camp On iMac 24" mid year 2009.

i through that Bootcamp was made by a third party, well we learn something new everyday

You're probably confusing it with the hack that was released shortly after Intel Macs were first made available, but before Apple released their first public beta of Bootcamp. Here's the link to it : http://www.onmac.net/

most drivers they use are from third parties (eg: ATI, nvidia) but Apple packages everything together and add the partitioning application for OSX (and the drivers for their own hardware)

I'm curious to see the improvements over BC 3.0. Windows 7 worked fine with the old stuff -- just way slow and power hungry. I hope the new drivers and whatever else Apple has done improves this. Seems like 7 runs way faster on every other machine I've installed it on, lol.

The biggest update was probably directed at fixing the bizarre display bugs that occurred on some of the more recent iMacs that made Windows 7 unusable. Windows 7 runs great on my MBP. My only complaint was the red-light from the audio port and the "power hungry" problem you described.

ah gotcha, thanks! Yeah, I also have been using it on my current gen MBP.
