Do the debug messages appear too small for your tired eyes? Fret not, you can change those to something larger if you like:
Head over to Xcode – Preferences and find the Fonts and Colors section. Switch to the Console Tab and select an option you want to change (typically Executable Console Output and Debugger Console Output appear in the debugger).
Now click the tiny little T icon at the bottom and change the font to something more palatable. The default font is Menlo 11.
Alternatively you can switch to either of the Presentation presets, which will increase the font size for the debugger and your code font (good for screencasts).
