Interesting how you will make a risk appetite decision for me. For all you know, I could be the CEO of a bank and need this. Regardless, key iOS/macOS features are broken, and downplaying the bugs isn't going to help end users who need to protect their Apple devices from 0-day, zero-click exploits that Apple seems to have to frequently patch due to vulnerabilities in their software.

If there are bugs, there’s nothing we can do about it. It’s not downplaying it’s we can’t do anything about it. When I read your post, I thought isn’t that what it’s supposed to do. Anyway probably the only way anybody here knows how to fix your problem is to turn off lockdown mode. if you want Apple to fix the “bugs“ contact them directly.

None of the bugs I described are on the list of disabled features: About Lockdown Mode - Apple Support

How do you know that there are bugs? That article says,

"When Lockdown Mode is enabled, your device won’t function like it typically does. To reduce the attack surface that potentially could be exploited by highly targeted mercenary spyware, certain apps, websites, and features are strictly limited for security and some experiences might not be available at all."

"When Lockdown Mode is enabled, some apps and features will function differently, including:"

Note that the article said "including", meaning that there could be other apps and features that using Lockdown Mode limits or breaks, and that the things in the list are just a few examples.

I’m seeing multiple, 100% reproducible failures tied to Lockdown Mode on macOS Tahoe 26.2 when used with an iPhone on iOS 26.2.

Question:

Is anyone else seeing these issues on Tahoe 26.2 + iOS 26.2? Any reliable workaround besides disabling Lockdown Mode (especially on macOS)?

I don't get it why Lockdown mode to begin with...?

I'm certainly not going to enable for some grins or confirmation—good luck with that.

If you were the CEO of a bank, you'd have an entire department to handle security on your work devices and, because you're the boss, they'd probably handle your personal devices as well. So, forgive us for not leaping to that conclusion.

You should certainly make your own decisions about risk. However, using a tool for something it isn't designed for can have unexpected consequences.

All of the limitations you describe are intentional, because all of them are potential pathways that could by used sophisticated professional hackers to subvert your iPhone. Lockdown mode is intended to protect high profile targets such as corporate executives, political leaders, journalists, drug kingpins and others on the world stage. The average user is not at risk, because the type of hacks it protects against require millions of dollars to implement.

I would expect full regression testing for a feature like this, especially since it would be executive-focused on high value targets of APTs.

Maybe it’s just your Mac.

Thank for the sermon

Have a great day

Perhaps you should consider leaving the platform for one that meets your security requirements.
