I fear this may be dumb but I can't get an installer. Download gives me an "install app" which opens to a folder "contents". Opening this gives me 4 subfolders: MacOS, info.plist, pkg.info, and Resources. Opening each and every one of these takes me no further down the path- either they don't have an app to open them (all things currently up-to-date ->v10.1.2,...)., or I get text gibberish. I tried to open in 9.2.1, but no different. At no time, did I see what I normally construe as an installer. Running on a Pismo 400mhz/20gb/324 mb. No problems otherwise with 10.1.2. Thanks!
