ARCHIVED: In Mac OS X, what does the startup icon mean?
When you power up a Mac, an icon will appear indicating whether the operation was successful. Icons include:
Gray apple or Happy Mac: No problems detected;
the system will continue to boot normally.
Flashing question mark: The computer is waiting
for you to insert a startup disk, or doesn't recognize your internal
hard drive as a valid startup disk.
Prohibitory sign or broken folder: Important
files in the operating system have been damaged or removed.
- Flashing globe: You are trying to start from a netboot server that doesn't exist or is offline.
