I have some questions about the behavior of encode. For example, with the following code, when we encode a very large string, the result is an empty array. So if memory allocation fails due to insufficient system memory or other reasons, and the returned Uint8Array is not successfully created, what will we get? An empty array, an exception, or an OOM crash? const encoder = new TextEncoder(); const encoded = encoder.encode(largeText);

I have an application which will launches another application as a child process. The child application does not need the dock icon, we use [NSApp setActivationPolicy: NSApplicationActivationPolicyAccessory]; to achieve it. However, I have discovered that the dock icon cannot be perfectly hidden. The number of recently used apps that aren’t already in dock(not choose keep in dock) less than three: The icon of the child application remains in the dock without being hidden. The number of recently used apps that aren’t already in dock(not choose keep in dock) more than three： The icon of the child application appears a few milliseconds. Even though add LSUIElement key in the Info.plist can work, we are seeking a programmatic modification.

I have an application running in the sandbox which launches an application bundle using NSTask. The main app entitlements enable sandbox add the User Selected File Read/Write permission. <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.files.user-selected.read-write</key> <true/> </dict> The child app entitlements enable sandbox and inherit. <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.inherit</key> <true/> </dict> When invoke NSSavePanel *savePanel = [NSSavePanel savePanel] in the child process, system will throw the error.The error message prompt that missing the User Selected File Read/Write permission. However, I have already added this permission in the main app, and I have set up the inherit in the child-process as well. The child process cannot add the User Selected File Read/Write permission again because it add sandbox and inherit in entitlements by the doc EnablingAppSandbox . It appears that the system is not inheriting this permission for the child process. panel[60195:2499353] [OpenSavePanels] Unable to display save panel: your app is missing the User Selected File Read/Write app sandbox entitlement. Please ensure that your app's target capabilities include the proper entitlements. And the error stack.
