Mac OS X 10 (version 10.5) introduced the ability to scale system icons up to 512x12 pixels, to make them larger.


If the "happy Macintosh" and the "Welcome to Macintosh" screens appear before the "sad Macintosh", the problem is probably in the system software.

When the "sad Macintosh" face appears immediately at power up, it usually means a hardware problem. Some of the common hardware issues are problems with SIMMs or hard drive.
