You are probably going to have to repackage their installer.app as a .pkg using a snapshot in Composer.

You can absolutely install silently on El Capitan, just maybe not with however they setup their installer.app.

We're successfully deploying using Ben's workflow https://macmule.com/2015/07/18/yet-another-sophos-enterprise-anti-virus-9-2-x-post/

@lkrasno Is that deploying 9.4 to 10.11? I've followed that guide, we've used it for older versions.

@Josh.A I've not got 9.4.. yet.. nor had much time to play with 10.11 :(

Can you try & report back?

If you haven't already, I'm happy for you to send the link @lkrasno posted to your Sophos support person. They need to get the message.

Agree we are in the same boat and had great luck with Composer.

I'd be wary of using Composer snapshots with Sophos installer.

Last one I deployed was 9.2 using @rtrouton method, and I won't be looking at el cap and 9.4 for a few months, but there's also this link from sophos with details to get the Mac in the right group as part of the install

How to automatically assign a Mac endpoint to a defined group in Sophos Enterprise Console

It seems to us that Sophos 9.2.8 works fine with El Cap. This is the current recommended, with 9.4.0 being on the preview release channel. My Mac is on the preview channel, and it updated from 9.2.7 to 9.4.0 automatically from our Sophos server.

We've reached out to Sophos tech support to confirm this article will allow silent installs:

Article ID: 119744
Title: How to create a pre-configured installer containing updating and On-Access scanning options
URL: https://sophos.com/kb/119744

I logged into our Sophos support page and it shows 9.2 supporting Mac OS X 10.6, 10.7, 10.8, 10.9, 10.10, 10.11

Morning everyone,

So it seems like there's lots of mixed responses here. I'll go through and try each one out and see how I get on.

@bentoms I did try using your method first (as we've used it in the past) but I may have done something wrong so I'll try again.

@dan.snelson Thanks for that link. Looks very promising also.

I'll report back ;)

Cheers.

@Josh.A Thanks.. i'd be very much interested in your findings.

Following Sophos article 119744, copying the entire contents of the .DMG to a temporary directory and then executing the following command in a post-install script seems to be working for us.

/path/to/tmp/folder/SophosMac9.4.0/Sophos Installer.app/Contents/MacOS/tools/InstallationDeployer --install

I banged my head against a wall with Sophos. I finally went the lazy route and setup an HTTP file server on my jds mac to deploy the installer. For some reason, I also get an error the first time I run it, so I run it twice. Sloppy but I just needed a solution. Albeit, I'm not using Enterprise. This is what worked for my for 10.11

A tail from a successful installation:

Just as an update for anyone following this.

We're still having no luck deploying Sophos silently to 10.11 machines.

I'll post again once we figure it out.

We're able to do a silent install on El Capitan by copying the .dmg and running the script below

"#!/bin/sh

Switch directories to Sophos Folder

cd /Library/temp/Sophos/Sophos Installer.app/Contents/MacOS/tools/

Install Sophos

sudo "./InstallationDeployer" --install

exit 0"
