I recently upgraded to El Capitan. Whenever I open an pdf file of more than 1 pages, Preview opens the sidebar. Is there a way to permanently disable it?
I was able to get this to work on 10.11.1 by adding a new key to the Preview.app plist.
You can use the defaults write command to do this in Terminal.
cd ~/Library/Containers/com.apple.Preview/Data/Library/Preferences/ defaults write com.apple.Preview PVPDFSuppressSidebarOnOpening true
At least, none that I am aware of, and I have looked. (I'd be thrilled to find out that I’m wrong!)
However, you can sort of brute-force as solution using Keyboard Maestro.
Here’s a macro that I made:
If you aren't familiar with Keyboard Maestro, what this is doing it waiting for Preview.app to launch or “activate” (i.e. if Preview.app is running and you switch to it from another app).
Then it waits until Preview.app has a window (in most cases that will mean a file has been opened).
Then it looks to see if the “Hide Sidebar” menu item exists but is not selected.
If all of those conditions are met, then it will select the “Hide Sidebar” menu item.
This isn’t a perfect solution, by far, but it might be better than nothing :-)
Sorry, but the plain terminal command
defaults write com.apple.Preview PVPDFSuppressSidebarOnOpening true did not work for me. After, Preview.app opened again showing the sidebar. I had to:
open (with Xcode) the file ~/Library/Preferences/com.apple.Preview.plist ;
Add a new item in Root with item name PVPDFSuppressSidebarOnOpening, item type Boolean and type value YES;
Save the plist file.
After that, Preview started opening without the sidebar.
I needed to use
defaults write com.apple.Preview PVPDFSuppressSidebarOnOpening 1
for it to work.
