Having waited with baited breath over the release ofÂ Mac OS X 10.7 Lion, I was disappointed to find out that my particular brand of MacBook Black (Intel Core Duo 2.0GHz from 2006 – EveryMac.com specÂ here) was officially not supported.

Testing conducted by Apple in November 2019 using preproduction 2.5GHz 28-core Intel Xeon W-based Mac Pro systems with 384GB of RAM and dual AMD Radeon Pro Vega II Duo graphics with 64GB of HBM2 each; and shipping 2.3GHz 18-core Intel Xeon W-based 27-inch iMac Pro systems with 256GB of RAM and Radeon Pro Vega 64X graphics with 16GB of HBM2, as.

– Processors AppleÂ willÂ officially support Mac OS X 10.7 Lion on are:

Any Core 2 Duo processor
Any Xeon Dual Core or better processor
Any Intel i3, i5 or i7 processor

– Processors AppleÂ will notÂ officially support Mac OS X 10.7 Lion on are:

Any PowerPC processor
An Intel Mac from the following:

iMac 4,1 2006 17″ / 20″
iMac 4,2 2006 17″
Mac Mini 1,1 Early & Late 2006
MacBook 1,1 13″ Mid-2006
MacBook Pro 1,1 15″ A1150 2006
MacBook Pro 1,2 17″ A1151 2006
MacBook Pro 1,1 15″ 2006

The discussion here is actually about supporting 32-bit vs. 64-bit. This solution works, as long as binaries included with the OS include 32-bit. As soon as these are removed (from Software Update and the like), then the solution will falter.

Now, not being one to give up on these things lightly, a little investigation reveals a simple method of getting the installer to run and upgrade this hardware. It seems that the only thing preventing a Lion installation on a 32-bit platform is a hidden (from the system, or available through Terminal) file that can be removed:

/System/Library/CoreServices/PlatformSupport.plist

There is a small gotcha to this, is that you need to install Lion to a supported platform first (such as a Core 2 Duo), then migrate that installation to the unsupported platform. During or immediately after the migration, the file above should be removed, so the migration will live happily on the unsupported hardware.

One suggestion I would make (as with all upgrades) is one of two routes prior to any upgrades:

Install the new OS to a separate partition, so there is always a roll-back or escape lane should (god forbid) anything go awry).
Ensure you have a full backup of your OS before installing / upgrading, using Time Machine to an external drive.

With all this, one thing is for certain – Apple won’t be releasing Lion support for legacy hardware, so if you have older hardware that wants to take advantage of the latest and greatest OS from Apple, solutions like this are looking to be the only way forward.

How to Switch

Mac OS X Tiger Now Enhanced for Intel Core 2 Duo

site
Apple Software | OS X

In their October 24, 2006 Press Release announcing the revised MacBook Pro line of professional notebook computers, Apple Computer mentions that the company's operating system, Mac OS X Tiger has been enhanced for the Intel Core 2 Duo processors.

The statement was embedded in the press release as follows:

'Apple has enhanced Mac OS® X to take advantage of the technology advances from Intel's Core 2 Duo processors, resulting in increased performance in professional applications like Aperture™ 1.5, Final Cut Pro® 5 and Logic Pro 7'
The new MacBook Pro's now join the iMac as the Macintosh models shipping with Intel Core 2 Duo processors. When the iMac Core 2 Duo models were announced on September 6, 2006, Mac OS X 10.4.7 was the latest version of the Tiger operating system. Mac OS X 10.4.8 was released on September 29, 2006. The new MacBook Pro's ship with 10.4.8 and the press release provides insight into the 10.4.8 enhancements that were not previously disclosed.
If Apple can further disseminate this information, I would expect that more buyers would consider purchasing a Mac over systems made by PC vendors.
Can Microsoft make a claim that their current shipping operating system Windows XP has been enhanced to leverage the Intel Core 2 Duo? Quite simply; No. This enhancement provides yet another advantage in the Mac OS X versus Windows OS comparison. The 'enhancement' announcement demonstrates the inherent modern architecture of the Mac OS X operating system and that Apple can introduce updates to a shipping version of their operating system to leverage new processor features and technologies.

Updates

October 24, 2006 - I've contacted Apple's PR department for information regarding the Mac OS X enhancements. Their reply didn't provide any useful information. If anyone has insight or details about the enhancements, please post a comment. Thanks.
