need to reformat to run on ac or plug & play?

If by "ac" you mean "Mac," yes for me it was "plug & play" with my new Mac Book Pro—either as as a backup destination using Time Machine or to copy anything else. No formatting was necessary. I ignored the option on mine of downloading "Discovery" for either Mac or Windows. That I don't need. Hope this helps.

What is included in the package when I buy this portable hard drive?

The package includes My Passport for Mac portable hard drive, SuperSpeed USB-A cable (5Gbps), USB-A to USB-C adapter, software for device management and backup with password protection, and a quick install guide.

How secure is my data on this portable drive?

The drive features password protection and 256-bit hardware encryption to secure your data.

Does the hard drive come with a warranty?

Yes, the hard drive comes with a 3-year limited warranty.
