I installed Jenkins with brew on mac. But it occurs some problem, I want to re-install it. Previously, at the first time I access http://localhost:8080, the page guides you to install some plugins and need you to input the password. But when I use 'brew uninstall jenkins' command and install again, the page will not show. I don't remember the previous default admin passsword. So I can't access the jenkins now. I delete the homebrew cache as well, it not worked. Is there any solutions to uninstall Jenkins completely? I just want to start from the beginning of the installation. Thanks.

Removing the .jenkins file is actually an answer, depending how Jenkins was installed. For example, the homebrew installation does create instance-specific work area in $HOME/.jenkins
If you have the jenkins instance already running, go to $JENKINS_BASE_URL/configure and check the value of 'Home directory' - that is the place where all user-specific data is stored, like the jobs.
PS: BTW - can't get away from SO stupidity. This is a comment to the answer by Ayobi, but don't have reputation to comment.
To uninstall Jenkins service from your Mac OS X computer, execute uninstall script from terminal:
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
/Library/Application Support/Jenkins/Uninstall.command
