but the programs don't show any freed up space (like in disk utility). If I do a cmd-i on the Macintosh Hard drive it shows 300+ gb, but disk utility is 70+gigabytes. FCP X shows the smaller amount. I've run the disc utility. It says everything is fine.
“You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed."
