Concerning, hidden dialog installing iOS 18.7

[DCIFRTHS]

During installation of iOS 18.7 on my iPhone 16 Pro using my MacBook Pro (Sequoia 15.7). When I clicked the "check for update" button, nothing happened. I waited, clicked again, rinse repeat etc. I moved the finder window used to update the phone, and there was a dialog box underneath.

I don't remember the exact wording, and I was negligent in that I didn't take a screenshot...

To sum up the dialog: I had the option of installing an update or refusing. I initially chose "no" thinking something was off because the dialog box was behind the finder window. It seemed like something had to be installed before the actual iOS update. I shut down, rebooted both phone and computer. Same thing happened on the next try, and with a second iPhone I have here. I was also concerned that it may have been a spoofed dialog box - yes, I am a bit paranoid.

I have run through what happened many times that my memory of the exact wording and steps is a bit off. I regret not jotting it down when it happened, and taking screenshots.

Could my Mac or iPhones be compromised in any way? I am concerned.

Has anyone seen anything similar to what I have described?

I’ve had something like that happen a bunch. Where iTunes seems to need to download something else using this little pop-up download window that’s unique to this situation. I can’t remember if all the details are similar to your situation, but it sounds super familiar.

Think it has to do with using an older macOS version which may be missing some software it needs to communicate with the latest iOS version

iTunes needs to be updated to communicate with your iPhone. It's normal when using an older version of Mac OS with a newer iPhone. My Mac running High Sierra also had to download an update to connect to my iPad Pro when updating to iPad OS 18.7 or 26. There's nothing abnormal or nefarious with the iTunes update pop-up to proceed with iOS update

My Version of MacOS was fully updated. There were no updates necessary when I updated to iOS 18.x.x using finder.app

Maybe it was an iOS 18.7 specific thing?

It’s because Apple periodically updates the OS components it calls “Device Support,” and that’s what was getting updated. It’s entirely normal and expected from time to time.

I corrected my post you quoted. It now reads:

Probably, but sometimes Apple will update Device Support anyway. It’s not something that appears in Software Update so you wouldn’t know an update is required or available until you get prompted to update.

I wish I had done a screenshot. It just looked "off" - the dialog box I mean. Can't put my finger on why. Maybe I'm overacting.

It's a totally legitimate update.

Thanks for the info. I appreciate it!

Possibly. I've had that pop-up before in previous versions of iOS (iOS17) when using iTunes to update. I go back and forth between OTA and iTunes to update my devices. I only use iTunes on new .0 releases, final releases and if my device is acting wonky and I have to restore. The iTunes update isn't a Mac OS update so it doesn't come through the App Store and there's no record of it being installed. The pop-up before installation is the only sign it happened..
