Fixed problem after Safe Boot, what happened?

I just did a clean install of 10.9 but after some tweaking Illustrator CS5 refused to start "you cant open the application Illustrator CS5 because it is not supported on this type of mac". Booted with cmd+opt+pr to reset pram but no luck. Strangely, when I created a new user that new user could start Illustrator.
Anyway, I booted the first user in safe mode (shift during boot) and it could start Illustrator, and then when I booted normally it worked!
So what exactly does Safe mode do? What did it change so that Illustrator then worked again in normal boot?
Safe mode does a fsck disk check and also flushes out cache files, so one of those things may have helped you. It also prevents startup items from launching.
No, fsck checks the file structure on the disk for errors. More similar to the "repair disk" you see there in Disk Utlity, but it is more thorough since it runs before the GUI and all is running.
Repair permissions ordinarily would not help with an issue like this.
Repair Disk Permissions does not have functions in common with Repair Disk.
You have to be booted to a different disk to run the Repair Disk function in Disk Utility, such as when you are booted to the Recovery disk.
