    Almost every reason to
    bind a Mac has an
    alternative approach.
    What are you actually
    getting from binding?
    Get out of that Bind

  9. Get out of that Bind
    “But we need to bind our Macs because…”

    • Certificates! and we use those for WiFi and VPN and stuff.

    • Network Shares and Printers.

    • Off-boarding and termination.

    • GPOs and AD group membership.

    • Consistent password experience.

    • Honestly, we don’t know why.

  11. Can We Practice… “Best Practice”
    Every environment is different.

    • There is no silver bullet

    • Unicorns don’t exist

    • You have to build your own Easy Button

    • Santa Clause Isn’t Real

    • It won’t work Every Single Time. That’s Okay.

  12. Can We Practice…“Best Practice”
    Pro Tips from our Jamfs in the field:

    • Eliminate redundant effort

    • Less Steps = Less Issues

    • Avoid Shotgun policy triggers

    • Sites are probably for someone else

    • Advanced Search whenever possible

    • Smart Group Abuse

    • Naming. Naming. Naming.

    Eliminate Redundant Effort
    Do not add the same
    package to multiple
    similar policies.
    Creates trouble and
    more work later.

  14. © JAMF Software, LLC
    Eliminate Redundant Effort
    DO: reference the main
    installation policy by
    using the custom trigger
    name: install_chrome
    Scope and frequency is
    controlled by each policy.

    Less Steps = Less to go Wrong
    Hey Rube Goldberg…
    Uh, It didn’t work‽
    Clever policy chains are risky.
    Script it whenever possible.
    No shame in having Hundreds
    of policies if organized.

    View full-size slide

  16. Shotgun Policy Triggers
    Usually its best to pick just One Trigger

    • “Why did that policy run?”

    • Custom triggers are powerful

    • To many triggers looses control

    • Scripting allows for full control

    • Move past “once per computer”

  17. Sites are probably for someone else
    Very few cases where it is helpful

    • Sites should be reserved for multiple
    distinct admin groups.

    • Used when different devices are managed
    separately in very different ways.

    • Meant to make things easier not to make
    more work for the jamf admin.

  18. Advanced Search - Hero. Friend.
    Do This.

  19. Advanced Search whenever possible
    • Doesn't Calculate until time of viewing

    • Not for scope, just metrics

    • No Excess Server Load

    • Great for reporting!

  20. Smart Group Abuse
    Constantly being Calculated

    • IS installed vs IS NOT installed

    • Too Many Criteria

    • Nested Groups in Nested Groups in Nested Groups…

    • Name it what it Does not what its For

    • Naming is so very important

    View full-size slide

  21. Whats in a Name?
    You decide. But please, Stick to it.

    • Be Specific. Be Accurate.

    • Little notes to Future You. ~Thanks Past Me.

    • Avoid naming TEST, Working, DONT DELETE ME

    • Stop with OLD, Disabled, DO NOT USE.

    • Clean House. Now is always the time.

    • Document the Naming Scheme!!!

  22. Paralysis from Analysis
    Fear of Change - common complaints:

    • Jamf management can be overwhelming.

    • Switching workflows is a really big deal.

    • Testing and getting approval takes too long.

    • We cant have an outage of any kind. ever.

    • “If it aint broke dont fix it.”

  23. Paralysis from Analysis
    Break it down in to easy to handle pieces

    1. Identify each issue that can be solved separately

    2. Solve each piece individually in a dev environment

    3. Figure out how to bolt them together

    4. Move it over into UAT or Pre Production Server.

    5. Success. Profit?

  24. Paralysis from Analysis
    Ideal Setup

    • Multiple Jamf test environments

    • VMs and Hypervisor are your best friends

    • Backups of Backups. Not Snapshots.

    • Do you really need Hot Spares?

    • Sandbox for playing

    • Test / Dev for testing and building

    • UAT / Preproduction for real world sanity checks

    • Jamf tools to move from one to the other

  26. Your Server Setup
    Do you even backup, Bro?

    • First, Have Backups

    • Snapshots are not backups and should not be trusted.

    • Backups of Backups.

    • Disaster recovery vs Hot spares

    • Clean. Lean. Fighting Jamf Machine!
