MacOS下LG超宽屏分屏软件功能问询：全屏模式行为验证

Hey there! Let me break down your questions about LG Screen Split on macOS, especially how it interacts with Apple's native FullScreen mode compared to tools like Divvy.

First off, LG Screen Split is primarily a window management tool—it helps you arrange app windows into predefined or custom partitions on your display, just like Divvy does. But when it comes to macOS's native FullScreen (the one that creates a dedicated Space, not just maximizing the window), here's the key behavior you should know:

• When you use LG Screen Split to position a window in a specific partition, then trigger Apple's native FullScreen mode (via the green dot or keyboard shortcut), the app will take over the entire display—not just the partition you had it in. This is exactly how Divvy behaves too.
• The root cause here is that macOS's native FullScreen is tightly tied to the system's Spaces feature. Any app entering native FullScreen creates a new, dedicated Space that spans the entire monitor by default. Third-party window managers like LG Screen Split or Divvy don't have control over this system-level behavior; they can only manipulate window positions and sizes, not override how Spaces operate.

If your goal is to have an app fill a specific partition on your ultrawide display without taking over the whole screen, skip the native FullScreen mode. Instead, use LG Screen Split's "maximize to partition" feature—this will stretch the window to fill the exact partition you've set, giving you a "fullscreen-like" experience within that section, without triggering the system's separate Space.
