How can I uninstall iTerm from my Mac? I searched a lot on the Internet but I didn't find any helpful Informations. I want to mention too that I installed iTerm without using Homebrew.
You need to provide more information on your issue. As Tetsujin linked, you can simply go to
/Applications and move the
iTerm app to the trash (see HERE). This is how you uninstall all macOS applications (unless you are using Homebrew). Any internet search can show you this step by step.
Now, I am guessing that you want to also uninstall all the hidden files that
iTerm creates on your computer. I would recommend taking a look at this tread which shows some other hidden file locations:
caches files in ~Library/Caches preferences files in ~Library/Preferences log files in ~Library/Logs Other files in ~Library/Containers ~Library/Cookies ~Library/Address Book Plug-Ins ~Library/Saved Application State ~private/var/db/BootCaches
You could manually delete iTerm's folders within these one at a time. Just be sure not to accidentally delete anything important to another application.
Now, you mentioned that you didn't install using Homebrew. I think you can still uninstall an application with Homebrew even if you didn't use Homebrew to install it. Usually using Brew you could just run:
brew uninstall --force iterm
You can add
--zap to get rid of hidden files in the
brew uninstall --force --zap iterm
If you don't have Homebrew, you can always go to the website. Search
iTerm and select
cask code. Then delete the files under zap trash from your computer after you've moved the iTerm application to the trash.
zap trash: [ "~/Library/Application Support/iTerm", "~/Library/Application Support/iTerm2", "~/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.googlecode.iterm2.sfl*", "~/Library/Caches/com.googlecode.iterm2", "~/Library/Cookies/com.googlecode.iterm2.binarycookies", "~/Library/Preferences/com.googlecode.iterm2.plist", "~/Library/Saved Application State/com.googlecode.iterm2.savedState", ]
