Apple has rolled out two major options for iPhone users: the stable iOS 18.7 and the feature-packed iOS 26. If you own an iPhone 15 Pro Max, you might be wondering which one is right for you. Let’s break it down clearly so you can make the best choice.

What’s New in iOS 18.7

• Security and bug fixes – keeps your device protected.
• No major design changes – feels familiar and stable.

What’s Exciting in iOS 26

This is a huge update with a complete makeover and next-gen features:

• Liquid Glass Design – glossy, transparent menus, fluid animations, and a futuristic UI.

Things to Watch Out For in iOS 26
