Tunnelblick for Mac

[Alex]

Hello,

I have a problem, I installed the latest version of TUNNELBLICK for my Mac Yosemite 10.10.5, but I can not edit the VPN configuration to add the .crt and .key files

It may not be compatible with Yosemite 10.10.5?

Thank you

If by "edit the VPN configuration", you mean "edit the OpenVPN configuration file":

"Private" configurations can be edited. "Shared" configurations cannot (nor can "Deployed" configurations). (This is because another user might be using the configuration.)

So to edit a "Shared" configuration, change it to be "Private", edit it, and then (if you want) change it back to be "Shared".

To change from "Shared" to "Private" or "Private" to "Shared", open Tunnelblick's "VPN Details" window. In the "Configurations" panel, click to select the configuration you want to deal with in the list on the left side, then click on the little "gear" menu at the bottom of the list of configurations and click on "Make Configuration Shared…" or "Make Configuration Private…".

If you mean "edit the configuration by adding files to it":

You can't directly edit a configuration by adding/removing files (and you shouldn't, for security reasons). Instead, what you do is create a new configuration in a convenient place (the Desktop, for example), give the new configuration the same name as the configuration you want to "edit", and then install the configuration by dragging/dropping it on the Tunnelblick icon in the status/menu bar. That will replace the old configuration in a secure way. For details, see Creating and Installing a Tunnelblick VPN Configuration.
