In public, yes, but presumably that doesn’t apply to security guards on Apple property.

In California, you cannot carry concealed except on your own property or on the property of a business you own.[1] Employees cannot carry concealed even if they have permission from the employer.

We’re back to “why concealed?”

Element of surprise.

And the public image nightmare in the liberal bay area of having all these guns in plain sight.

What? Bay Area banks and retail stores routinely have conspicuous security guards open carrying. Not to mention police, which also exist and are commonly seen in the Bay Area.

I imagine Apple's security team was interested in procuring CCW permits for use beyond Apple's property. Probably for executive security and things along those lines.

You're right that carry permits are not required on private property.

True. I guess I don't know why they'd need a license at all to do that, since I think Apple can allow people to carry within its own buildings however they'd like.
