‘Fix’ allows you to install Windows Bootcamp on new iMacs with 3TB drives

If you haven’t heard, those who purchased a new Mac with Apple’s built-to-order 3TB hard drive option found themselves unable to utilize Boot Camp assistant to install Windows. Boot Camp Assistant is currently limited to drives up to 2.2TB. Apple hinted that support might come at a later date, but TwoCanoes shares a step-by-step guide for getting the job done in Boot Camp until then:

Since it is not possible to get around the 2.2 TB limitation with booting Windows, it is possible to organize the partitions so that Windows is the last of the first four partitons and is within the first 2.2 TBs of space on the drive. Since the Mac can see the remaining space above the 2.2 TB limit, this space can be used for addtional storage space for OS X.

In order for Windows to boot successfully and still be able to utilize all of the available space on a 3 TB (or larger) hard drive, Windows must be installed on the fourth partition. You can use Disk Utility to create the partition, but since Disk Utility does not show hidden partitions, it can be difficult to see what is going on if some partitions are hidden. To have Disk Utility show hidden partitions, open Terminal and run the following command:

Mountain Lion installed on a MacPro1,1, here’s how to do it

As pointed out by OWC, a step-by-step instruction guide has popped up courtesy of Mac user Jabbawok that details the steps necessary to get Mountain Lion running on a MacPro1.1 (the models first introduced in 2006). It is not the easiest process ever, forcing you to upgrade the graphics card, have access to a spare SATA HDD, and go through a couple of dozen or so more steps inside Chameleon bootloader, terminal, and elsewhere. The good news is this means there are not a lot of Intel Macs that won’t be able to handle Mountain Lion. You can check out the instructions here, if you are interested, and the author gave a brief explanation below on what prevents the MacPro1.1 models from running Mountain Lion in the first place:

There are two things that prevent 10.8 from installing on a MacPro 1,1. The first is the lack of EFI64. Mountain Lion as has no support for 32bit kernel and extensions so it will not boot. This is true of many early Intel macs… The other thing is that checks are made by the installer; against a supported machines list. If your mac isn’t on the list, it refuses to install.

On a related note, you might make use of popular Mac backup and cloning app Carbon Copy Cloner throughout the process. The app was just updated to version 3.5 with a number of new features including Mountain Lion compatibility.
