Okie Dokie!
About three days ago my computer refused to wake up from sleep.
OK...so I just shut it down as it had been on for a number of days without 'rest'.
I turn it back on, but no finder! WTF? OK...don't panic, I thought to myself - just zap the PRAM! Done! but...problem not fixed.
I ran diskwarrior...fixed a few things. Fixed a few permission errors with the disk utility. I thought all was OK.
Well...apparently not! What to do? I booted in safe mode. All was OK. My computer was running a bit slow, there was no WiFi available, and not many multimedia functions...but at least all my files were OK. I ran the apple hardware check, to see if there was some other part of my laptop that was not functioning properly, but all came back normal!
Next up? The format and reinstall! I did a backup...although it appears my photos were not backed up :(, formatted and reinstalled the OS.
STILL...the darned thing only works when booted in safe boot mode....oy! WTF is going on?

At least Rapidweaver is working in Safe Mode! :)
