Kbase Article of the Week: Mac OS X: Terminal window is too small, or doesn‘t appear →

This seems like a weird bug:

Terminal is a utility for executing command line instructions in Mac OS X. If its window is very small and can’t be resized (Mac OS X 10.3, 10.4), or does not appear at all when Terminal is opened (in Mac OS X 10.5) make sure the Monaco font is enabled.

Terminal needs Apple’s Monaco font. If that font is disabled or missing, the Terminal window will be very small and unusable, or may not appear at all.
