the no-longer-existing services in Server or the missing Rosetta support), some people will have to stick. Second, especially with an upgrade that technically cannot run everything that worked before (e.g. First of all, some older hardware may be too slow or not have enough capacity to run Lion, but may still be sufficient for real world use. The user base has now certainly grown to a point where not everyone can simply upgrade to a new major release.

That last link shows all 2012 MacBook Air shipped originally with 10.7 so you would not expect 10.6 to have the drivers needed for full compatibility.I'd sincerely hope Apple will continue to upgrade Snow Leopard with bug fixes and updated peripherial hardware support like print drivers, etc. (use to look at older versions of support articles).Some of those items you can get around with USB adapters, other items you can't get around since the kernel and low level drivers are just not present to start up unsupported machines. On iMacs, typical failure modes are WiFi not working and AirDrop / bonjour not working. Lastly, some people use an installer to install from a supported machine to an external drive and then take that drive to the Mac that's not supported and see how badly things break when you boot. You can know the exact build and version of the potential installers and go through the documentation to see which models 'support' that installer.įurthermore, even if you don't have Apple official support, then you can see if you want to consider modifying the OS to hack it to try the install anyhow and see how badly it breaks. This really ends up build you asking yourself 'What installer do you have to install 10.6.8?'
