Apple - Control odd-even page pairing in Preview in two-page mode
I recommend to add a blank page as the new first page:
- Menu View->Contact Sheet
- Click page 1
- Menu Edit->Insert->Blank page
- Move the new blank page to the first place
- Now you can view it in 2-page mode.
I have been bothered by this for a long time. By accident, I have discovered a bug of Preview. And I have noticed that by exploiting this bug we can change the pairing.
By default, Preview displays pages in two-page mode like this:
page 1
page 2, page 3
page 4, page 5
etc.
To change the pairing, click on the view icon on the toolbar and choose Continuous Scroll or Single Page (or simply press Command+1 or Command+2), then right click on the pages and choose Two Pages or Two Pages Continuous.
To change it back, click on the view icon on the toolbar and choose Two Page (or simply press Command+3).
I didn't find any way to display facing pages the other way in Preview. In Skim you can uncheck PDF > PDF Display > Book Mode.
