OP:
I opened Mojave Books, double click a pdf in Books, it opens in Preview.
Restarted holding apple+R, Terminal/ csrutil disable/ return/ restart/
Terminal/cleared launch services/few errors, see attached jpg/
Apple+I, a pdf, a jpeg, affinity photo doc, psd doc, individually changed the ALL SIMILAR Docs setting
Restarted holding apple+R/Terminal/csrutil enable/return/restart/
Opened Mojave Books, double-click a pdf in Books, it opens in Preview.
I only want pdf's to open in my pdf editor, ONLY. What else is there?
Anyone got a terminal command for Mojave in Terminal as I asked before?
What does it matter what brand pdf editor? I'm assigning default opening apps. PDFExpert
Addendum: I am now seeing (90%) MOST pdfs in Mojave Books double-click open in Mojave Preview, but some special long multipage pdfs open in PDFXpert as I want ALL pdfs to open. What the heck is going on?
