PDF cause Computer to Freeze and/or Lag

[Antny1]

My 2018 Macbook pro currently running Mojave v 10.14.5. After the last update, I have experienced immense computer freezing and/or lag when working on PDFs (and only when working on PDFs). Actions that cause the problem include: downloading PDF (regardless of size), moving PDF from one folder to another, saving a PDF after editing in preview. My default PDF editor/viewer is preview. I'm unsure if the latest update caused the issue or the timing is merely coincidental.


I hope someone can help. Thank you.

What PDF application are you using? I'm not having any problems with Preview or PDF Expert on my 2018 15" on 10.14.5

I use preview as my default editor/viewer. If the PDF requires more extensive editing, I use PDF Element 6 pro. However, the issue does not arise during PDF editing.

Hmm, I was working with PDF invoices yesterday, downloading PDFs from sheets.google.com, but I've had Mojave freeze up on me 10 times now doing anything! It comes and goes. Started with 10.14.5 for me. Although some say it started with 10.14.4 https://forums.macrumors.com/threads/mac-os-10-14-4-freezes.2175025/page-2
