OSX sslcacertfile and GMail (Basic help)

[M. Henry Linder]

Hey all

Per the “10 minute rule” on the website, I’m looking for some very basic help:

I’m on OS X, with offlineimap and openssl installed through homebrew. I can’t for the life of me find a CA certfile or PEM file that Gmail will accept. It seems that I may need to generate a certfile from the keychain; how might I do that? Let me know if anything isn’t clear and I can try to explain further…

Thanks for any help!
Best
Henry
