Help, please, I have my old and faithful Mac book, (13 inch 2.4Ghz intel core duo, 3gb memory, 250 HD.)which runs perfectly well, but when I run Disk Utility I am informed that the HD capacity is 238.24GB, Available 45.75GB, Used 192.48 GB. When I use grand perspective, and disk inventory I am told that there is only about 40.5 GB used. Using the get info facility, I can find out that; Applications = 6.16 GB System files =135MB Library=. 8.5GB Resources = 26 Bytes Users =. 18.9 GB System =. 4.92 GB I have run verify disk etc, erase free space, and even the maintenance scripts, nothing helps. What is going on? How do I get the machine to find all the free space? Oh yes, I am running 10.7.3, and everything is up to date. Any help gratefully accepted!!
