Preview eats up half (7.9GB) of my memory

This happens every time, the memory that preview occupies increases monotonically without upper limit. The only thing to prevent is to cmd-Q to quit.

And reopen is also problematic: after it opens I can scroll for a (not long) while, afterwards preview gets freezed for several tens of seconds and then recovers, this also happens everytime.

This issue seems to have started with the ibook pdf syncing functionality.

MacBook Pro with Retina display, OS X El Capitan (10.11.4)

Do a backup.

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
