Aloha everyone, I have read the thread that lists the apps that apparently don't work under Lion. When I installed DP4 on a blank hard drive, I got the same results. However, when I installed Snow Leopard, loaded up all the apps I normally use (with the exception of Xcode), then upgraded to Lion, everything worked! Yes, iStat Menus 2.0 (the last free one) and Geek Tool are both operating as normal. Unfortunately, Icns2Rsrc.app no longer works, as even support for PPC apps has been completely stripped (I knew that I could no longer install Rosetta, but thought that if Rosetta was already installed, I may still be able to use it). Does anyone know of another app that can convert from .icns to .rsrc? Those image files are particularly useful if you, like I, like to create custom icons for internal and external hard drives. To repeat, if you install Snow Leopard and upgrade to Lion, as per Apple's instructions, as long as iStat Menus and Geek Tool are both installed prior to the upgrade to Lion, they will both still work as expected under Lion. Those are two apps upon which I have to come to rely more and more. While I liked the additional features of iStat Menus 3.0, I think I'll stick with iStat Menus 2.0 myself, at least for the time being.
