It appears that Disk Utility on my new Macbook Pro 15 is still trying to use (or may actually be using?) the "PGP WDE” formatting scheme that should no longer be on my Mac and that this may be what is causing a host of problems in how my Sierra running new MBP works when asked to format disks. I removed PGP Desktop 10 from my prior Macbook in 2015.
Please see this link below - which is a dated (but ultimately inconclusive for my purposes) dialogue showing how a Symantec tech named Michael Arkeny tried to help someone remove the offending PGP partitioning scheme reference. In my case, my Mac frequently tells me that a third party partitioning scheme was used to format disks (com_pgp_wde_GUIDPartitionScheme_v2) and cites this as the reason that I can not, for example, create a recovery disk on external drives that I format or partition (and this result/blockage is the same, irrespective of whether I partitioned/formatted the disk in question with Apple's Disk Utility or with Drive Genius 4, by the way).
Can Symantec kindly conjure a Terminal script or other solution that will eradicate this lingering (!) PGP partitioning scheme problem? I simply want it removed so that my new Mac uses the default Apple partitioning/formatting schemes and so that I am assured that PGP is entirely removed permanently.
Please see this, not completely on point thread; perhaps it may offer a helping lead?:

Also kindly note that I already ran through and entered all of Terminal commands recommended at the following link, but this does not seem to have removed the PGP formatting/partitioning demon (!):

Finally, Mike Bombich at Carbon Copy Cloner also has tried to help me with this, but we did not manage to find, remove or otherwise make whatever changes may be needed to rid my Mac of this problem.
Your kind and prompt assistance will be greatly appreciated!
Best, Tom
