UPDATE: If you are having issue with libssl.1.0.0.dylib instead of libcrypto.1.0.0.dylib (mind the difference), please try the solution in Stackoverflow: brew switch openssl 1.0.2t.

Recently, Homebrew drops OpenSSL v1.0 for v1.1. The popular TagUI Github issue suggests downgrading openssl to v1.0 because their stack hasn’t support v1.1 yet. But that’s not a good idea in general. This posts presents my solution to the specific issue I saw.

When I reinstalled openssl v1.1, git suddently not working:

$ git fetch origin
dyld: Library not loaded: /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib
  Referenced from: /usr/local/bin/ssh
  Reason: image not found
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

When you read the message, it was quite clear: ssh is not working. My solution is as simple as

brew upgrade openssh

The new openssh version works fine with openssl v1.1

$ brew info openssh                                                                                                                                             [10:29:34]
