Having waited with baited breath over the release of 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 spec here) was officially not supported.
– Processors Apple will 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
Get the latest stable version of Clementine for your operating system. Debian Jessie 64-bit. Mac OS X development builds; Ubuntu Precise (12.04) development. Mac OS X/OS X/macOS. The internal codenames of Mac OS X 10.0 through 10.2 are big cats. In Mac OS X 10.2, the internal codename 'Jaguar' was used as a public name, and, for subsequent Mac OS X releases and for OS X 10.9, big cat names were used as public names and wine names were used as internal codenames.
But while the public-facing builds were named after big cats, internally, they were named after wines (aside from OS X 10.6 and macOS 10.13, both of which had no codename). Mac OS X Lion 10.7.5. An icon used to represent a menu that can be toggled by interacting with this icon.
- Any PowerPC processor
- An Intel Mac from the following:

- 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.
