wrongly accused of commended on appearing to own an example of every single Mac ever produced. The actual truth is, that, over time, I have accumulated a sizable zoo of Intel-based Macs, all running OS X 10.6 (Snow Leopard). And, with this week’s release of the latest iteration of Mac OS, Lion, I most certainly wanted to upgrade as many of these machines as possible, if only to have the same scrolling direction on all of them.
However, it appears that that’s not always as easy as Apple wants to make us believe. For example, I have a fairly recent 13,3″-MacBook Pro, which should be supported, but refuses all straightforward attempts to upgrade its operating system and just boots into the old one. Also, my (Lion-supported) media-center Mac mini crashed twice halfway into the upgrade process. To make things more complicated, my old 2006 MacBook Pro (featuring a 32-bit-only Core Duo processor) is not officially supported by Lion. In fact, it was only my Mac Pro that was fine with the “just download the Lion Installer through the App store and run it” approach.
In this post I’d like to share a number of different ways to install Lion that I found (mostly on the web) as solutions to very different installation problems.
