How do I stop this extremely annoying dialogue box?
I can't duplicate your problem. I've tried all 3 of these preferences in Preview
and do not get any warning. I'm opening the image files in Preview by dragging a folder of image files onto the Preview icon in the Dock and going thru the File ➙ Open menu option.
Boot into Safe Mode, Mac OS X: Starting up in Safe Mode, and try from there. Reboot normally and try again.
25 items seems to be the number that triggers it.
I can open 24 without being asked.
And here is the Automator action that was mentioned.
All it takes is to assign it a keyboard shortcut, and then you can select, press the shortcut and they all open. It may require a bit of retraining not to press command-O, or command-down, as you may be used to, but there it is.
Unless you can find some undocumented plist entry, you might have to create an automator action.
OK, read it over, thank you. Say I have a folder with 50 images in them. I take a lot of pictures for my work. When I select all of them and want to open them all in Preview, I hit command O to open and instead of opening them immediately, I get a dialogue box that says, "Are you sure you want to open 50 items?" I can select Cancel or I can select Open. Since I do this type of operation a lot, I just want all of the images to open as it has done since 1985. Yes, I've used Macs since 1985. The dialogue box is completely unnecessary and very annoying. Thank you for your help!
Thanks for all the testing and replies. How strange that some machines do it and some don't. My iMac is a 4.2 i7 with 16 GB of ram and Radeon Pro 575 with 4096 MB. 24 files is the most I can select and open without the dialog box.

How do I do that Keith?
FWIW, I get no warnings either. Tried over 180 files.
I do get a warning but I have not established what the threshold is.
I will try later when I have some time on my mac.
The warning may occur based on how much available memory there is. I didn't find a limit but I'm on a 32GB machine.
I opened 277 images on my iMac with 16 GB memory and no warning.
I am also running 10.14.1 Mojave
