A graphical Macintosh application does not usually have a console/terminal window.
You can achieve this by supplying the keyword argument console :input
when delivering your application.
Output to *terminal-io*
from an application without a console/terminal window will not ordinarily be visible to the user, so debugging messages should be written to a log file.
Log files are recommended for any complex application as they make it easier for you to get information back from your users.
You can use dbg:log-bug-form
for logging errors. See the
LispWorks User Guide and Reference Manual
for details.
