puppet facter mac model

Question

I'm creating a puppet manifest and I'm trying to use a built in facter variable based on the MAC model. I'm using this guide: https://docs.puppetlabs.com/facter/3.1/core_facts.html

I saw system_profiler with an option for model_identifier but I'm not sure what the correct syntax is.

Here is where I'm confused:

class::something::mac
if $<% system_profiler %> eq "macpro"; then
do the thing
else
don't do the thing

Where/how do I actually use model_identifier? I'm new to puppet and MAC so any advice would be great!

Answer 1

My current facter version v2.4 doesn't support it, but I can't successfully install latest facter v3.1.4, so can't test the code. It should be closed for your question.

if $::system_profiler::model_identifier == "MacBookPro10,2" {
   do the thing
}
else {
   don't do the thing
}

Run the command on your mac to prove it.
