So this article is written with the main aim to dual boot Maverick and Windows 10 64bit. So in the meantime I have downgraded to Maverick to enjoy a more stable environment. It is unfortunate that a supposedly stable OS based on the Mach kernel can be so sentimental at times. A quick search on Google suggest that I am not alone in this. It is completely random and very frustrating. I have had Yosemite installed on my 24″ iMac but find that it has been giving me random reboot from time to time. These days it does not make a lot of sense to use a 32bit OS unless we are dealing with really really old hardware with 2GB ram or less.

Wouldn’t it be great if we can install Windows 10 on the iMac to make it even more useful? And while we are at it, why not make this a 64bit install too. In fact Windows 10 with its “ Compact OS” feature have an even smaller footprint than Windows 8.1. Windows 8.1 and Windows 10 is known to run well on older hardware. I think the iMac 2007 is a reliable machine and still looks gorgeous by today’s standard and it will be great to be able to extend its life for a few more years. The 24″ iMac 2007 is an 8 year old desktop and most people would deem this as a dinosaur in today’s context.

ATI Radeon 2600 Pro with 256MB GDDR3 memory (The 20″ iMac with 2.0Ghz Core 2 Duo has a slightly slower ATI Radeon HD 2400 XT with 128MB of GDDR3 memory).

This is the iMac 2007 spec just in case anyone is not aware: IMac 2007 – 8 year-old technology that is just as good in year 2015 Unfortunately a 32bit OS cannot take full advantage of the 4GB of ram and a 64bit OS is required. So running anything beyond this means you are on your own when it comes to having issues. Apple says the iMac only can run up to Windows 7 32-bit. Many people have installed Windows 7 32bit onto the iMac 2007 and many people have also successfully upgraded this to Windows 8.1 32bit. Apple officially supports Windows 7 32bit running on a bootcamp partition. While BootCamp 6 is great for those people who are lucky enough to buy or own any Mac later than 2012, it is not so useful for people like me who are still using older desktop such as the 24″ iMac 2007.įor the iMac 2007, the BootCamp support stops at version 4. See here: Įssentially BootCamp allows Windows to be installed on another partition (called the BootCamp partition) on the same Mac hard drive (or SSD) this allows the user to easily dual boot the Mac between MacOS and Windows.

Following the release of Windows 10, Apple has also updated their Windows 10 support via BootCamp v6.
