Try reseting the preferences , There is a quick and easy method for doing this using the keyboard: close and relaunch InDesign, and IMMEDIATELY hold down Cmd + Ctrl + Opt + Shift (Mac), and respond in the affirmative to the dialog asking if you really want to replace the preferences.
or rename US_en here
Macintosh: Hard Drive/Users/<USER>/Library/Preferences/Adobe InDesign/<Version #>/<Language>/
but I've already tried reseting prefs. deleting caches and so on, but nothing seems to work. InDesign seems to create the same corrupt/uncomplete prefs all the time.
Try this create a new administrator account (for test launch) and try launching Indesign and see if you can get the panels and menus there.
If you do get the panels and menus than there is some problem with the permissions on your this account.
You can reset the permissions using this link
Repair File & Folder Permissions
File permission problems can arise when Mac OS X is updated. This can prevent our games from launching and may cause them to unexpectedly quit when certain game features are accessed. Use the steps below to repair file permission settings on your hard drive.
Using Finder, navigate to the /Applications directory.
Right-click the game folder and select Get Info.
In the info box, go to the Sharing & Permissions section and click on the lock to unlock it. Enter your administrator password when prompted.
Make sure all privileges are set to Read & Write.
Click on the Burst icon (cogwheel) and select Apply to all enclosed items. Select Yes to confirm the action.
Note: Step 5 must be done, even if the folder already displays Read & Write privileges. This helps ensure all enclosed files have the same permissions.
Waht method did you use to replace the prefs?
Was this a clean install of ID on a fresh OS, or did you do an inplace update or migration of any sort?
The system was updated to 10.8.3 (from 10.8.2). InDesign is a full install, no updating.
Tried reparing permission, didn't do it, neither did the new admin account trick...
Pref were reomved both manually from /Preferences/Adobe/Adobe InDesign/ and with keyboard short cut.
If the new account didn't work it most likely means a problem in the install. Did it ever work?
I'd sugest uninstalling, running the clean tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3), then restart the Mac in Safe Mode (hold down Shift while you start up), then run the installer again.
After a complete uninstall, running the CS Cleaner and then installing in Safe Mode, InD CS6 finally is up and running!
Virtual flowers to all of you!!
