Description:
Am running mac osx 10.13.3 with LO 6.1.0.0.alpha0+ Master and GPG Suite 2018.1 (gpgtools.org).

I have an issue with Digital Signatures. After raising the issue on https://bugs.documentfoundation.org/show_bug.cgi?id=89037#c9 I was advised to try and test on Master and the situation remains the same.

Basically no Digital signatures are listed in File/Digital Signatures/Digital Signatures even though I have a valid OpenPGP key (Usable in Mail.app).

Clicking on Start Certificate manager, I get an error "Could not find any certificate manager".

Documentation is scanty on the process involved in Mac OS but from reviewing what the official documetation describes (Windows) it seems LO is unable to pick  keys/certificates from the GPG Suite or even recognize the suite as a valid certificate manager.

Am willing to try out any leads, pointers that may be availed.

Steps to Reproduce:
1. Save document on Mac OS LO
2. Go to File/Digital Signatures/Digital Signatures.
3. Click on Start Certificate Manager.

Actual Results:  
Nothing is listed on the Digital Signatures.
An error is displayed on clicking Start Certficate Manager. "Could not find any certificate manager"

Expected Results:
List the keys in GPG Keychain and be able to appy them to the current document.


Reproducible: Always
