Of course, if you need Preview 9.0 for all users, rename it to Preview9.app and move it to the root Applications folder in the sidebar.Īlternatively, just download Preview 9.0 from your old source, put it on your desktop, and when you want to open multiple pdfs in one page, drag and drop them onto the app icon. Set Preview.app (9.0) as default PDF Viewer for all PDFs ( Instructions).Move Preview.app to your User/Applications folder (not the one in the sidebar, but in your Home folder - create it if necessary).Copy Preview.app with version 9.0 from a computer still running macOS Sierra, or from a Time Machine backup (or download from said repo above).I've taken this from the Github repo I specifically created for this reason, as to retain and make accessible a version of Preview 9.0: The only known solution to me is to continue using Preview 9.0. High Sierra added tabs in Preview 10.0, so no more multiple PDFs in a single window.

Manually: Manually choose when to use tabs, whether or not you're using the app in full screen. In Full Screen Only: When you open another window in your app, it opens as a tab only if you're using the app in full screen. ^From the option menu, you have the following options:Īlways: When you open another window in your app, it automatically opens as a tab in your current window. Now, when you open multiple PDFs they will open within the same window, segmented by different tabs.

You can open multiple PDFs in the same window, but the UI is different. Has anybody found a solution to opening multiple PDFs in the same window in High Sierra? This is pretty vexing, right now im leaning on the conclusion that apple had some how changed how preview app works, unless there is another hidden preview setting location some where. I tried getting my old ~/Library/Containers//fluff and replaced whatever setting I have right now ( it worked before ), and unfortunately I still cannot view multiple PDFs in the same window ( without using tabs ). So this should be the correct setting, at least from what I know. I know opening multiple PDFs in the same window was possible at least in Sierra, I have no idea if they changed anything for High Sierra that caused this to fail. However, for PDFs this setting does not seem to work. I have the option to open groups of files in same window setting turned on, and this works for pictures.
