Update to OS Xv10.14
I have a mid-2010 iMac running High Sierra 10.13.6. I just noticed that I cannot get updates for Pages, Numbers, Keynote and iMovie with this version. Should I update to V10.14 or keep 10.13.6? I am afraid if I update, my printer and apps may not work. Last time I had to buy a new printer and some things did not work. What are my options? Everything works perfectly now.
Thanks for any input.
iMac 21.5", macOS 10.13
