Craft 3 dashboard error Having successfully installed Craft 3 via composer – all seems fine but on each load of the admin dashboard I get a notice on red bg: 
'An unknown error occurred' need I worry about this? couldn't see anything obvious in the logs – all else seems fine – using php 7.0.0 / Mamp Pro and used the line below when setting up:

PATH="/Applications/MAMP/bin/php/php7.0.0/bin:$PATH"


Or is a fresh install required?
If you're running MAMP (and even if you're not, but it's common you are) and you're getting this error when connecting to Craft's web services:


  cURL error 35: Unknown SSL protocol error in connection to craftcms.com:443


Then you're running an older version of MAMP and you need to upgrade to the latest.

The older versions are trying to connect over https using an older SSL protocol (TLS 1.0) that is no longer supported.
