I made the mistake of telling Adobe Reader to be my default for pdfs. (I was having an issue trying to print pdfs from Preview, thought a switch would help.) Now I cannot get Preview to open for anything (e.g., for jpg's), not even if I go to the application folder and double click the Preview app. HELP!

Select any PDF document. Press option+command+i. On that panel, is a section named Open With, and you will probably see the Adobe Reader application icon set as default. Change that selector to Preview, and click through the Change All… button. Once you have done that, Preview should now be the default opening application for PDF.
Good luck with the command i >Open With and making all the changes.
Adobe kept hijacking all my pdf. — I eventually had to delete Adobe Reader.
There is a re-occuring bug that seems to hijack Preview, images opening in Graphic Convertor and others, no matter how many times I reset: Alwyas Open With and Open With
I have seen this happen in both High Sierra, and Mojave— I believe the 10.14.3 may have resolved that issue for now.
Thanks to both of you! Leroy, after I followed VikingOSX's directions, I also deleted/uninstalled Reader so the hijack you mention won't happen again. Just FYI, I am running 10.14.3, not sure exactly when the (recent) hijack occurred, whether before or after I move from x.x.2 to x.x.3 One other note of possible interest - before I got your replies, I thought a simple Restart might help me get Preview back, at least temporarily. But System would not Restart or ShutDown. opt-cmd-esc showed that Preview was still "running". ,Even though I was unable to Open or use it. I tried to Quit, could not Quit. So I did a hard ShutDown with the power key. I'll come back to this thread if I have further issues - again, thank you both!
How can I reload Preview
