Finding and accessing opt isn’t as simple as finding other hidden folders. In this article, we explain why and how to find and access the opt folder.
How to find the opt folder?
Opt For Clue
This isn’t as easy to find as a Library or even Net or var because macOS does not even have an opt (or /opt) folder. Instead, macOS has a /usr/local/opt folder, something you can make visible in Finder.
Ordinarily, you aren't going to need to find and access the /usr/local/opt folder unless you need to download new software applications from third-party providers, such as Intel or Homebrew.
Whatever the format you find opt within your macOS directory, the purpose of this folder is: “a directory for installing unbundled packages (i.e., packages not part of the Operating System distribution, but provided by an independent source), each one in its own subdirectory.”
Navigating to this opt folder can be done one of two ways: either go through Terminal or search for it using Finder.
How to find opt folder using Terminal
- Go to Terminal - in the Utilities folder.
- Type in the following command:
defaults write com.apple.Finder AppleShowAllFiles YES
- Now Reinitialize the Finder, either by rebooting or clicking the Finder while holding down the Option key, then selecting “Relaunch.”
- Now, this should show every hidden folder, including the /usr/local/opt folder.
- Once you are ready to hide them again, go to Terminal and input the following command:
defaults write com.apple.Finder AppleShowAllFiles NO
How to access the Opt folder using the Finder
- Open Finder.
- Press Command+Shift+G to open the dialogue box.
- Input the following search: /usr/local/opt
- Now you should have temporary access, so you should be able to drag it into the Finder favorites if you want to access it again.
