For a description of what I’ll be talking about, please see the IT804: Managing Mavericks’ FileVault2 with fdesetup session page, which is linked on the MacIT Wednesday Full Agenda page.

Payload-Free Package Creator.app

March 8, 2014 3 comments

I do a lot of work with payload-free packages and I’ve looked for a while for a tool that would let me easily create them from existing scripts. While I have a process for creating them as needed with pkgbuild, this approach still requires some setup work.

After thinking about it and taking a look at various approaches, I’ve developed Payload-Free Package Creator.app, an Automator application that will allow the selection of an existing script and create a payload-free package that runs the selected script. For more details, see below the jump.

Deploying Sophos Anti-Virus for Mac OS X 9.x

February 20, 2014 4 comments

For the past few major releases, Sophos used a standard installer package to install both their free and paid antivirus solution. With the release of Sophos Anti-Virus 9.x though, Sophos changed how their antivirus solution for Macs was installed by switching to using an application to install it. For their customers using Sophos Enterprise Console, Sophos will still provide a installer metapackage, but all other customers now need to use the application to install Sophos Anti-Virus 9.x on Macs.

Curiously, Sophos went to some lengths to make their install application look like a standard installer package.

This extended to the point of naming the actual application as Installer, which is the same name as Apple’s Installer.

This switch away from using installer packages was a problem for Mac admins who wanted to deploy Sophos 9.x, but did not have Sophos’ enterprise console. After doing some research and reading a very helpful thread on JAMF Nation, it looks like it is possible to repackage Sophos 9.x for deployment. For more details, see below the jump.

Managing the Authorization Database in OS X Mavericks

February 16, 2014 2 comments

Prior to OS X Mavericks, the /etc/authorization XML file controlled the rights for many different actions, such as adding a printer, setting up Time Machine or setting DVD region codes. Modifying this file required root access and could be performed with a text editor. The /etc/authorization file could also be modified by using the security command line tool included with OS X, but most chose not to do so because directly editing the file was easier.

With the release of OS X Mavericks, /etc/authorization has been removed in favor of a new authorization database, which is a SQLite database located at /var/db/auth.db. There is also an authorization.plist file located in /System/Library/Security, which is used by the OS as a template for a new /var/db/auth.db database file, in the event that the OS detects on boot that /var/db/auth.db does not exist.

To see what’s in the database, you can export the database to a text file using the following command:

sudo sqlite3 auth.db .dump > /path/to/filename.txt

It’s also possible to open the exported data directly inside text editors that support this option. For example, the following command can be used to export the database and automatically open the exported data in a new TextWrangler document:

sudo sqlite3 auth.db .dump | edit

Power Nap, power management settings and FileVault 2

February 12, 2014 3 comments

I recently purchased a new MacBook Pro Retina for my own use and encrypted it with FileVault 2. As part of setting it up, I ran the following command to ensure that the laptop hibernated (where the contents of the RAM are written to disk) and also have the FileVault 2 key automatically removed from the saved RAM state when I put the laptop to sleep:

sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25

I then put my laptop to sleep and shortly thereafter went to sleep myself.

The next morning, I went to wake up my laptop. I expected to see my account icon and a password blank at the FileVault 2 login screen, which would indicate that it had been asleep.

Instead, I saw the icons for all of the FileVault 2-enabled accounts on my laptop.

That indicated that my laptop had turned off instead of being asleep. For more details, see below the jump.

Deploying Xerox print drivers on a per-OS basis via Casper’s Self Service

February 10, 2014 Leave a comment

In my shop, we use a Xerox color copier/printer along with a number of Canon ImageRunner printers. Like the Canons, I have the Xerox printer available in Casper’s Self Service so that our users can set this printer up themselves on their Macs. When I recently overhauled my Canon printer setups, I decided to also revisit how Self Service handled setting up the Xerox printer. Unlike our Canon printers, our Xerox printer used LPR already so I figured that getting the right drivers deployed should be straightforward.

Then I looked at Xerox’s driver page and saw three different driver installers available:

For 10.5.x – Xerox Print Driver 2.94.3

For 10.6.x – Xerox Print Driver 2.112.0

For 10.7.x through 10.9.x – Xerox Print Driver 2.113.0

I wanted to maintain roughly the same workflow as I had with the Canon printers, but I also wanted to make sure that the OS-appropriate driver was delivered to each Mac.

For details on how I addressed this, see below the jump.

Deploying Canon print drivers with printer setups via Casper’s Self Service

February 6, 2014 3 comments

In my shop, we use a number of Canon ImageRunner printers and have them set up in Casper’s Self Service so that our users can set them up themselves. All of the Canon printers in question have PostScript enabled, so I’ve been deploying the Canon PostScript drivers.

Historically, one of the things that was installed along with the drivers was a proprietary printing application that sat between the Mac’s CUPS printing system and the actual printer. That changed with the release of Canon’s 4.x PostScript drivers. With the new drivers, Canon has switched to using LPR and no longer uses that proprietary printing application.

Good news: Canon is no longer building in a custom printer program to handle talking to the printer; instead the new drivers are using LPR.

Bad news: Our existing printer setups that are available in Self Service do not work with the new printer drivers. I would need to delete and re-add our various printers to Self Service.

The bad news wasn’t a big problem by itself, but my testing showed that updating the printers in Self Service to accommodate the new printer drivers would make them no longer backwards-compatible with the old drivers. The new drivers would need to be installed in order for the new printers to work. Conversely, just pushing out the new drivers to our Macs could result in existing printer setups breaking.

In short, here were the problems I was looking at:

1. The old printer setups could not use the new drivers

2. The new printer setups could not use the old drivers

3. The new drivers needed to be installed before the new printer setup happened.

4. I didn’t want to break existing printer setups if I could avoid it.

Making the new drivers available in Self Service as standalone installers wasn’t an issue but I was concerned about adding them to the printer setups themselves. That potentially could result in the printer drivers being installed over and over again as people set up multiple printers on one Mac. I also wanted to avoid problems with accidentally trying to overwrite newer drivers, in the event that Canon released new drivers and someone installed them before I updated the driver installer in Self Service.

For details on how I addressed this, see below the jump.
