PersistentID

Q: Can older computers have identical PersistentIDs?

 

In my EMR/Practice management software (PaperCutPro, http://www.papercutpro.com) I record the ID of the machine from the Get (PersistentID) function within the database. My understanding from the documentation, and my experience have shown that these are unique within my small office network of computers except for two machines. I have two older white plastic cased MacBooks with OS X 10.7.5 on 2 GHz Intel Core 2 Duo CPUs with 4 gb of ram that return the exact same PersistentID.

 

Q: Is the PersistentID not actually then unique, or is this an anomaly because of the aged hardware, the OS X 10.7.5 system software, or both?

 

My wondering is that perhaps the older machines do not have the hardware capability to create a unique id with PersistentID and thus are simply all returning the same ID?

 

Comments and discussion on this appreciated.
