Xcode Built SequelPro Throws Error #3310

  • Sequel Pro Version: Cloned the latest repository
  • macOS Version: 10.12.6
  • MySQL Version: 5.7

I successfully cloned and built it using Xcode. While trying to connect to MySQL through SSH tunnel, it throws following error. I am fairly new to Xcode and Objective C and the reason I am building is because enhancement #3227 can't be fixed. So I thought I would make some local changes and build a custom version for my use. I am done with my changes and the app launches well although it asks me for Keychain every time I launch, probably because the build signatures are different each time (but this is a secondary issue and I can live with it).

I tried different architectures and deployment targets but same issue. I am building using the based macOS SDK 10.13. I have the official version deployed and I have no issues with that.

I do not think the issue is with reach the MySQL host but it has to do with incompatible libraries as if I am building a 32 bit version trying using 64 bit libraries.
Please advise.

Unable to connect to host, or the request timed out.

Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

MySQL said: Authentication plugin 'dialog' cannot be loaded: dlopen(/usr/local/mysql/lib/plugin/, 2): no suitable image found. Did find:

That is a runtime issue, not a build issue.
The server requests the cleartext/dialog auth plugin, which is not supported by Sequel Pro (see #2996).
However the MySQL client library finds a file on your machine which it thinks it could use to do dialog auth, but it can't (/usr/local/mysql/lib/plugin/

That file is completely unrelated to Sequel Pro and part of some other MySQL installation on your Mac.

But I have the official Sequel Pro client installed which runs flawlessly. Should it also not exhibit the same behavior?

Sequel Pro 1.1.2 uses a much older version of the MySQL client libraries
