2. I use File Info to confirm: Permissions (Me) has Read and Write, Fetching has Read, Everyone has Read.
3. I drag to Zotero Library.
4. I click on the Zotero pdf to open (or use Zotero View PDF, or Show File, then click to open in Preview... same result as follows occurs)
5. I attempt to use Preview to Markup the document.
6. Preview says: "The original document can't be changed, so a duplicate with your changes has been created")
7. Show Info confirms the Zotero pdf file has Permissions= (Me) has Read and Write, Fetching has Read, Everyone has Read.
8. Curiously, the pulldown file menu in the middle of Preview shows the WRONG path to the file.
I think it should show: Zotero Data Directory Location: Users/Showroom ([Me]/Library/Application Support/Firefox/Profiles/o4hrtze1.default/zotero
... But instead, the path is to a directory to which I recently saved another pdf.
... So I am wondering if Sierra and/or Preview app has changed malevolently in some way, rather than Zotero?
I've only the problem in association with pdf files I want to annotate that are in my Zotero library. I haven't tested this exhaustively. However, if I randomly select both old and newly created pdf files from my Zotero library, the same result appears.
I'm pretty sure the problem has only become obviously apparent strongly in the last week or two. However, since I installed Sierra in September 2016, I've not been using my Zotero since this week, as I have been on an extended travel away from my base computer.
I am about to begin investigating whether this feature is more widely known in the Apple discussions. I did note that Apple is introducing a new file system in Sierra....

I'll also repair permissions on my Mac disk, though I'm pretty sure I did that a week or two ago.
Postscript
I trawled through Apple Discussion Boards that lead me to another Zotero Discussion on the topic:
macOS Sierra: papers protected? (2016, July 19). Retrieved 5 January 2017, from https://forums.zotero.org/discussion/61014/macos-sierra-papers-protected
In summary, the fault appears to be that Sierra forbids editing using Preview of pdf files stored in /Library/Application Support/blah blah.
Zotero 5.0 intends to fix the problem by moving the Zotero library elsewhere. A Beta Zotero 5.0 is available. Follow the link above.
Here is the more general Apple discussion to which I refer:
