Software update required
Trying to transfer photos from iPhone 11 Pro Max 13.5.1 to Mac Mojave 10.14.6 via Lightning to USB cable. Message says I need to update to latest OS X software. Does this mean I must update to Catalina? I have documents and spreadsheets that I will not be able to access if I do that. What now?
