If I do would I need to install X again? Should I be prepared for any hitches once it is removed / other configurations I should change in the process? Answer #1: Not if you are ABSOLUTELY certain that you will never need the Classic environment again. Answer #2: a - Drag the OS-9 system folder to the trash and delete it. Be darned sure that you have the OS-9 System Folder and not the System Folder. b - No. c - Not unless you try to access a program that is OS-9 only. d - See "c". Over-all answer: As long as you are ONLY using OS-X compatible programs and equipment, you should see no problems at all. One problem that may arise is when you discover that you don't have the OS-X version of a program and have to go to the store to buy it. Your wallet may file a complaint because it is being emptied too frequently for its peace of mind. Side comment: Since OS-9 really does not take that much space on the hard drive, why is it necessary to remove it? At most, it takes less than 250Mb and can even be pared down to take less than 160Mb by removing sub-programs that are duplicates of functions that OS-X will manage for you. Unless you have small capacity drives, under 20Gb, I would just leave it there as a "possibly needed program" for use if ever the need arises. HTH
