Problems viewing documents in Preview
When I open documents, especially pdf's of blueprints I get text on top of text. The text is doubled.
How do I solve this problem?
Quit Preview.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Remove the following. You may not find them all. Restart and test.
Containers/com.apple.Preview
Containers/com.apple.quicklook.ui.helper
Preferences/com.apple.Preview.LSSharedFileList.plist
Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist
Saved Application State/com.apple.Preview.savedState
