Reset Printer Queue

TIL (thing I learned)

Had a user upgrade to macOS 10.14.1 and no printers showed up anymore.

So using my Google fu I found some posts (see one below) which described a novel way to reset the print queue on macOS. An old trick apparently. Learn something new everyday.

A quick trip to a terminal and it worked! The existing printers returned to System Preferences and printing resumed.

Final Cut Pro X 10.4.4 update

Apple released a new update for Final Cut Pro X, v.10.4.4 and this adds many new features. Many were on the wish lists of Final Cut Pro editors. Also some surprises were included with the update: the inclusion of third party extensions which allow integrations unlike we’ve seen before. Excited to see what’s going to develop in that area.

Editors from around the world are gathered in Cupertino at the FCPX Creative Summit for news about the updates and to share ideas, workflows and learn from one another.

To find out more about the recent updates check out these blog posts and videos made by members of the Final Cut Pro X community. Enjoy.

Blocking minor major macOS upgrades

Continuing our theme of welcoming our new macOS overlords, uh, I mean, blocking major macOS upgrades such as macOS 10.14 Mojave with AppBlock we shall examine some other methods of stopping the freight train known as Apple upgrades.

1) A smart person on the MacAdmins Slack posted a useful command to tell macOS not to download major upgrades.

In their testing, running:

`software update –ignore macOSInstallerNotification_GM`

blocks the installation of the Mojave notification package (at /Library/Bundles/OSXNotification.bundle).

However if it already installed, then it’s too late. They pushed out this command prior to that package being distributed by Apple, and they could subsequently see in install.log that the update is being found by softwareupdated but not being installed.

2) If you missed the chance to tell the Mac not to download major macOS upgrades then Rick Heil on his blog has detailed a way using munki to delete the bundle that triggers the macOS upgrade installer.

3) App Block

If your users are intent or their computers are all hell bent on downloading the install app then block it with App block detailed in my previously mentioned blog post

4) Warning

In an effort to get an early warning when users are about to upgrade I use Watchman Monitoring to send me an alert email when a Mac starts downloading the Install macOS app. Sometimes it’s enough of a warning to send an email to a user to ask them whether it is a good idea to upgrade at this time. If storage or software needed for production or backups aren’t qualified or tested thoroughly beforehand then upgrading in the early waves can be less than ideal and frought with peril.

In other interesting and related news, Victor (MicroMDM) was spelunking into the MDM Protocol for what prompts Macs like iOS devices to download major updates. Great post here

If you have any better ways to block macOS upgrades or want to contribute some great solutions let me know. Cheers

 

 

 

 

To install macOS Mojave, or not to?

InstallMojave

Just the other day macOS Mojave was released and now the armies of Macs armed only with the AppStore are silently downloading the installer and ready to upgrade. You can’t hurry too fast to be on the bleeding edge, hurry faster!

Just in case you don’t want everyone to install macOS 10.14.0 (dot zero!) in the first week of its release here’s a way to slow down the upgrade hordes using Erik Berglund’s AppBlocker script. Erik Berglund is also the author of ProfileCreator (for creating profiles) and the author of many other great scripts.

Note: for true binary whitelisting check out Google’s Santa project and Upvote (and Moroz and Zentral, two other Santa sync servers).

Step 1. Get it

Clone or download the AppBlocker project from GitHub

AppleBlockerProject.png

Step 2. Do it

Edit the AppBlocker.py script with the Bundle Identifier of your app to block, in this case for the Mojave installer from the AppStore it is:

com.apple.InstallAssistant.Mojave

You can also edit the alert message, and the icon that is shown, as well as decide if the blocked app should be deleted or not. The script is easy to edit in BBEdit, or nano (in Terminal). Use whatever your favorite text editor is to make the necessary changes.

# List of all blocked bundle identifiers. Can use regexes.
blockedBundleIdentifiers = ['com.apple.InstallAssistant.Mojave']

# Whether the blocked application should be deleted if launched
deleteBlockedApplication = False

# Whether the user should be alerted that the launched applicaion was blocked
alertUser = True

# Message displayed to the user when application is blocked
alertMessage = "The application \"{appname}\" has been blocked by IT"
alertInformativeText = "Contact your administrator for more information"

# Use a custom Icon for the alert. If none is defined here, the Python rocketship will be shown.
alertIconPath = "/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Actions.icns"

UPDATED NOTE:

To determine the Bundle identifier of other applications you can use osascript

osascript -e 'id of app "iTunes"'
com.apple.iTunes

If you want to block more than one app use a comma separated list in the AppBlocker.py script:

['com.apple.InstallAssistant.Mojave','com.apple.iTunes']

 

Step 3. Run it

Put the script where you want to run it. The default location as defined in the launchd plist included with the app is “/usr/local/bin”. Put the launchd.plist in “/Library/LaunchDaemons/” and start up your launchd to block your apps!

launchctl load /Library/LaunchDaemons/com.github.erikberglund.AppBlocker.plist

Step 4. Automate it

For bonus points we automate! Bundle it all up in a package with munkipkg, then distribute it with Munki to all your clients.

Using munkipkg is easy. Create the folder using munkipkg

./munkipkg --create AppBlocker

munkipkg: Created new package project at AppBlocker

Then you fill the payload folders with those items you downloaded from the AppBlocker project. LauchD plist in the LaunchDaemons folder and AppBlocker.py in the “usr local bin” (create each nested folder).

AppBlocker-Munkipkg3.png

And finally create a post install script (no “.sh”) with the launchctl action to start your plist.

AppBlocker-Munkipkg4.png

Last but not least add this package to your Munki repo as an unattended managed install  that everyone gets. Of course, only do this after testing your package locally somewhere to verify that it works properly. Remember the saying: “You may not test very often, but when you do it’s always in production.” Be very careful with your testing but always automate all the things.

Updated after the initial blog post to explain how to add more than one app to block, and how to use osascript to determine the bundle identifier.

 

 

 

PostLab: FCP X + GitLab

Final Cut Pro X and Shared Projects: FINALLY !!

I’ve been playing with PostLab the last few days. It’s a free and open source app that lets you use GitLab with Final Cut Pro X to do version control of editing projects. Yes, this is very cool. Shared Projects, Read only versions of projects. Versions. Of. Projects. Commented. Makes it awesome to work on projects together.

Of course, like any workflow app it can be annoying to those who don’t want to play along. But I like the price and the simplicity of it. Using GitLab means you can have free private repos for shared project sharing. You can use their website on the internet to act as your gateway or you can setup your own internal GitLab server. For Free.

PostLab is pretty awesome with its Final Cut Pro X project sharing and it’s not $100K app that is expensive to setup and everyone hates it. It’s free and some people might not use it, but it could allow for effective remote workflows and nice finely grained version control for projects that need it even in an internal on site production SAN environments.

It’s worth checking out.

https://www.postlab.app/

Install PostLab, and the Xcode cli tools. Then launch PostLab, agree to the license, authorize accessibility for PostLab to enable it to launch FCPX. And you’re on your way.

All that’s left is to configure a GitLab account. Set u a group and a project. Configure token in GitLab to Enable PostLab with GitLab account access. Then start sharing projects. Enjoy.

Lots of cool set up videos on the PostLab website. Robot narrator says Jit-Lab instead of “Git” Lab, but it’s still worth watching. Do it now.

P5 on the Jellyfish: Archiving Gotchas

TL;DR

Using Archiware P5 to Archive files to tapes is awesome, but watch out for little things you might miss, such as the path to the files and backing up your Archive Db.

P5 Archive on the Jellyfish

Using P5 Archive with the Lumaforge Jellyfish is a great way to preserve your digital archives. See this post for how to set up P5 on the Jellyfish

Using Archiware P5 for archiving makes sense. You want your completed projects and original camera footage on LTO tape. But how do you do archives? There are several different ways, and there be gotchas.

P5 Archive vs P5 Archive app

Using P5 Archive to manually archive completed projects to LTO tape is a process of logging into the server via a web browser and selecting the the project folder you want to archive to tape.

The completed project folder could be on the storage visible to the server or it could be storage the client sees. And that can make a difference. Where the storage is mounted is different on a Mac vs Linux. Its’ the difference between “/Volumes” and “/mnt”.

The same Jellyfish storage, either SMB or NFS, when seen on a Mac is mounted by default at “/Volumes” (this can be changed but for most people leave it at the default). But when archiving the storage via a Jellyfish client you will get “/mnt” path.

p5-smb-test2.png

Using the P5 Archive app, which is a Mac only companion application to P5 Archive, to run the archives you will see the storage archived as “/Volumes”.

This first Archiving gotcha is if you’re archiving the Jellyfish storage with the web application of P5 Archive you will have to find your footage and restore from the “/mnt” path vs if you’re archiving from the P5 Archive app which is running from a Mac and will see and store the footage using the “/Volumes” path.

All this to say that using both ways to archive may double up your footage in your archive which may be unintended. And from a restore in the web browser finding your footage may be confusing if you’re used to seeing it mounted in “/Volumes” and you actually find it under “/mnt”.

Note: the reason to use the P5 Archive app is because of the simplicity of right-clicking files in the finder which are on your storage and telling them to archive right then and there. Files are copied to tape then the original files on the storage are replaced with stub files. Right-click again to restore. Simple.

Backup your Archive!

Don’t forget to backup your archives. Or rather, your archive Db. A more recent addition is the ability to automate the backups on the Archive index, so don’t forget to enable it.

In the managed index section, choose your Archive index.

Set the target client where the backups are going and the backup directory. Choose a time and don’t forget to enable it (check the checkbox and hit apply before closing the windows).

Note: Repeat this setup for each Archive index you want to backup.

Monitoring your Archive!

Don’t forget to enable email notifications for your P5 server to get your inbox full of status notifications and errors and other important stuff. But if you want to cut down on email notifications or you have multiple P5 servers (many different clients, perhaps), then you might want to check out Watchman Monitoring and the P5 plugin that is built-in). Find out easily when your tape pools are getting low, the tape drives needs to be cleaned, the support maintenance needs renewing etc. All in one dashboard. How convenient!

Maybe everything is going well…

Install P5 on the Jellyfish

TL;DR

You can easily install Archiware P5 backup and archive software on a Lumaforge Jellyfish storage server. Once you’ve done that you can backup to tape or disk or the cloud directly or through another P5 server. Backups are good. Archive are good. Restores are better.

P5 install on the Jellyfish (Linux) How-To:

Note: Thank you to Lumaforge’s CTO Eric Altman who gave me some basic instructions to get me going.

Step One: Download the latest Linux P5 rpm file 

http://p5.archiware.com/download

p5-Linux-rpm.png

Copy the downloaded rpm file to the root folder of your SMB or NFS file share.

 

Step Two: Install the rpm file

Open Terminal and ssh into your Jellyfish. Login as root or as another appropriate user.

yum localinstall /mnt/Primary/ShareSMB/awpst554.rpm

 

Step Three: Browse to server on port 8000 to test that the server is up

e.g. https://jellyfish:8000

Or in Terminal and ssh into your Jellyfish and ping your P5 server

cd /usr/local/aw 

./ping-server

Pinging PresStore application servers...

  lexxsrv pid: 4840 (server is running)

  lexxsrv url: http://127.0.1.1:8000/login 

Pinged 1 from 1 application servers.

 

Step Four: Decide if the Jellyfish storage will be a P5 client or a server.

Note: If configuring the Jellyfish storage as the main P5 server you may wish to set up a user that only has access to the shared volumes.

For my set up the Jellyfish storage is going to act as a P5 client to a main P5 server on a Mac mini (yes, they are useful for something). The Mac mini is this case is the P5 server and is attached to theOverland tape library via a Promise SANlink2 Thunderbolt Fibre Channel adapter.

Step Five: Set up the Jellyfish storage as a P5 client

Log into your P5 server and add the Jellyfish by the IP known to the P5 server. In this case the P5 server is connected via 1GB to the Jellyfish in Port 1.

P5 clients jellyfish setup1.png

Note: You could also choose to plug into the Jellyfish via a 10GB port, but in my setup these 10GB ports are reserved for the edit stations. You should choose what’s appropriate for your setup.

P5 clients jellyfish setup2.png

Resource utilization of P5 on the server is low, topping off generally at 1GB of RAM at peak usage. While this does technically take resources from ZFS caching, the impact should be super minimal.

In my observations the CPU never spiked too high while both serving NFS and SMB mount points to multiple Final Cut Pro X workstations even with backups or archive jobs going to tape at the same time.
