The menu bar
1 The menu bar is split by type of job. The customisation functions are all in Parameters.
2 Each group is further divided into tabbed sections. Tabs denote the application or OS function being customised. The number of options in each section varies widely.
3 The Restore Defaults button is your friend. If your Mac starts to behave unexpectedly, press it to put things back the way they were and problems should disappear.
4 OnyX will either make a change immediately, need to restart Finder, or even take over your Mac for a few minutes.
