Question

我最近注意到我的应用程序无法再发送kAESleep，kAEReallyLogOut和kAEShutDown等系统事件，而且我不能为我的生活找出原因。

我只能说，它在6个月前我上次测试这些特定选项时起作用了。从那以后，我可能已经升级了Xcode和操作系统本身，所以也许在引擎盖下发生了一些变化。

（非投掷）错误： 2018-04-22 10:24:36.548501+1000 <APP-NAME>[15698:628777] AppleEvents: received mach msg which wasn't complex type as expected in getMemoryReference.

我的功能看起来像这样（借用https://forums.developer.apple.com/thread/90702）：

private func sendSystemCommand(command: AEEventID) throws {
    var psn = ProcessSerialNumber(highLongOfPSN: UInt32(0), lowLongOfPSN: UInt32(kSystemProcess))
    let target = NSAppleEventDescriptor(descriptorType: typeProcessSerialNumber, bytes: &psn, length: MemoryLayout.size(ofValue: psn))
    let event = NSAppleEventDescriptor(
        eventClass: kCoreEventClass,
        eventID: command,
        targetDescriptor: target,
        returnID: AEReturnID(kAutoGenerateReturnID),
        transactionID: AETransactionID(kAnyTransactionID)
    )
    _ = try event.sendEvent(options: [.defaultOptions], timeout: TimeInterval(kAEDefaultTimeout))
}

实施如下：

do {
    try self.sendSystemCommand(command: kAEShutDown)
    print("Shutting down")
} catch {
    print("Error sending `shut down` command to system")
}

有什么想法吗？

编辑：经过多次来回，我相信这种行为是由应用沙盒系统引起的。我可以通过发送像osascript -e 'tell application "System Events" to shut down'这样的系统命令来观察同样的问题。该命令从终端shell按预期工作，但从我的应用程序发送时返回错误。

我一直认为应用程序可以请求发送系统事件命令的权限，但我无法弄清楚 - 它似乎没有得到很好的记录。

尝试为topics.invert.invert添加com.apple.security.temporary-exception.apple-events的权利：

com.apple.systemevents

我有这个问题，我用Objective C这样做

OSStatus SendAppleEventToSystemProcess(AEEventID EventToSend) {
AEAddressDesc targetDesc;
static const ProcessSerialNumber kPSNOfSystemProcess = { 0, kSystemProcess };
AppleEvent eventReply = { typeNull, NULL };
AppleEvent appleEventToSend = { typeNull, NULL };

OSStatus error = noErr;

error = AECreateDesc(typeProcessSerialNumber, &kPSNOfSystemProcess, sizeof(kPSNOfSystemProcess), &targetDesc);

if (error != noErr) {
    return error;
}

error = AECreateAppleEvent(kCoreEventClass, EventToSend, &targetDesc, kAutoGenerateReturnID, kAnyTransactionID, &appleEventToSend);

AEDisposeDesc(&targetDesc);

if (error != noErr) {
    return error;
}

error = AESend(&appleEventToSend, &eventReply, kAENoReply, kAENormalPriority, kAEDefaultTimeout, NULL, NULL);

// error = AESendMessage（＆amp; appleEventToSend，＆amp; eventReply，kAENormalPriority，kAEDefaultTimeout）;

AEDisposeDesc(&appleEventToSend);

if (error != noErr) {
    return error;
}

AEDisposeDesc(&eventReply);
return error;

}

无法将AppleEvent发送到系统进程
