Hi Ronni Reset PRAM. Not sure of your intention. Is is to do with fixing the Startup Chime? Or general housekeeping following Disk Warrior repairs?
Later I re-installed OS X Mavericks (from OS X Utilities). Thirty minutes download (via WiFi) plus 42 minutes installation. I didn’t check functions after PRAM reset. But some functions left problematic after Disk Warrior are now OK (checked after Mavericks re-installed). (a) Now no alert message re iTunes invalid certificate (was “iTunes can’t verify the identity of the server “init.itunes.apple.com”). Now plays local music and connects to iTunes Store without problems (b) Sudoku app loads and operates normally - previously got message that the app was damaged and to download a new copy. (c) Dropbox seems to be OK, but may not have beeen “inactive” as I thought yesterday. (d) Startup Chime: this has worked every time today. The “little squeak” noted still occurs sometimes at the very start of the chime. I will do further monitoring to see if there are Chime differences depending on the shut-down mode. Possibly had no start chime when I turned power off at the rear switch. So PRAM reset plus Mavericks re-install have raised performance. I have not connected the external hard drives (videos) which will put iTunes (and the iMac) to a real test.
