I have now installed Mac OS X Lion on the kid’s computer. Well it’s a good test machine and it it goes all wrong, I can just format and reinstall Snow Leopard. It’s an older Core 2 Duo iMac so not state of the art, but still does a great job as a home computer.
The install process was quick and easy and the Mac seems to work just fine.
There are quite a few old apps on there and some now no longer work as they were for my old PowerPC Mac and relied on Rosetta, which isn’t part of Lion and doesn’t work on Lion.
No real problem as I don’t use those apps myself, but something to be aware of if you do use older apps. To find which Rosetta apps are on your system, use System Profiler.
System Profiler > Software > Applications
Select by Kind and look for PowerPC.
These apps won’t work in Lion, do you will either need to find alternative apps or not upgrade!
Though there are some fundamental differences between Snow Leopard and Lion, you can “ignore” much of the changes and have a system that feels and looks more like Snow Leopard than the iOSation of many of the features of Lion.
Having said that I quite like Launchpad and certainly much easier to use than the Applications folder in Finder.
Still not 100% sure if I will install Lion on my main production iMac as I do have a couple of key PowerPC apps that I still use and there aren’t currently Universal or Intel alternatives. Also still have a few concerns about Adobe. What I will do though is install it on an external drive connected to my iMac and by using that on a regular basis I will have a much better idea if I like it or not.
