I installed isync on my personal Macbook, which runs OSX 10.11. I used the exact same
.mbsyncrc file I wrote for my Macbook at work.
The setup works fine on my work machine. However when using the mbsync command on the personal machine, I get the following output:
SSL error connecting imap.gmail.com (220.127.116.11:993): error:00000014:lib(0):func(0):SSL lib
The work macbook runs a fresh install of OSX 10.11 and Homebrew. The personal one also runs OSX 10.11 and Homebrew, but has known several upgrades since 2013 (it was mountain lion at the time).
Are you aware of any difference between fresh installs and upgrades, that could lead to this kind of error?
