# Library not loaded: libcrypto.1.0.0.dylib issue in mac

You might have come across this error while dealing with the openssl module. Inorder to solve this issue follow the following steps Step 1: Install openssl using brew
brew install openssl
Step 2: Copy copy libssl.1.0.0.dylib and libcrypto.1.0.0.dylib
cd /usr/local/Cellar/openssl/1.0.1f/lib
sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/
Note the bold folder name. There will be change in that depending on your openssl version Edit (2019 July) If you are getting permission denied error even after sudo. Try copying to `/usr/local/lib ` instead. Thanks to George Hotz from comments to pointing it out. Step 3: Remove the existing links
sudo rm libssl.dylib libcrypto.dylib
sudo ln -s libssl.1.0.0.dylib libssl.dylib
sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib
That’s it. Now try installing what you have been trying to install. I hope this helps. If you need any further clarification, do comment. Enjoy :-)

    Thank you!
    Now I'm getting a "Symbol not found: _SSLv2_client_method" "Expected in: /usr/lib/libssl.1.0.0.dylib"
    Found a StackOverflow issue about it here: https://stackoverflow.com/questions/25492787/ruby-bundle-symbol-not-found-sslv2-client-method-loaderror
    My system is a bit out-of-sync due to a major hard disk crash.

    in my case,
    i was already having homebrew and openssl

    just needed to unlink and link:

    brew unlink openssl
    brew link openssl --force

    did the trick

    Did a brew unlink openssl to get the path and version and then followed the tutorial.
    Awesome !

  20. SMITH SHAH· 2019-02-08

    For sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/ it says operation not permitted

  21. George Hotz· 2019-06-20

    copy in /usr/local/lib instead.
