Mac OS X中的应用程序更新
要在Windows中提供应用程序更新，我们只需下载安装程序并运行它即可.应用程序安装在％PROGRAMFILES％中，快捷方式放置在各个位置.键和值将添加到注册表中，以在系统的程序"列表中提供一个条目.
To provide application updates in Windows, we can simply download the installer and run it. Applications are installed in %PROGRAMFILES% and shortcuts are placed in various places. Keys and values are added to the registry to provide an entry in the system's Programs list.
要在Linux中提供应用程序更新，我们可以使用系统的程序包管理器.

如何在Mac OS X中提供应用程序更新?我认为通常您只是将.app捆绑包拖到/Applications?除了在/Applications文件夹中查找"以外，系统是否提供其他类型的注册表?更新的一般流程是否应该仅涉及下载打开的DMG文件，提示用户将新的应用程序捆绑包拖到/Applications中?将应用程序捆绑包复制到文件夹之前，会在复制之前删除现有捆绑包吗，还是像普通文件夹一样工作(例如，添加和替换现有文件)?我只想了解一些有关如何实现与Mac OS X应用程序预期一致的检查更新"功能的一般信息.
How do you provide application updates in Mac OS X? I think in general you simply drag .app bundles to /Applications? Does the system provide any sort of registry other than "look in /Applications folder"? Should the general flow of updating simply involve downloading an opening a DMG file, prompting the user to drag the new application bundle into /Applications? Will copying an app bundle to a folder delete the existing bundle before copying, or does it act like a normal folder (e.g. add and replace existing files)? I'd just like some general information on how I know go about implementing a 'check for updates' feature consistent with what's expected for a Mac OS X application.

以我作为Mac 用户(不是Cocoa开发人员)的经验，它已成为自我更新应用程序的事实上的标准，除了Microsoft Office和Adobe CS之类的独石之外.
In my experience as a Mac user (not a Cocoa dev), it's become the de facto standard for self-updating apps, save for a few monoliths like Microsoft Office and Adobe CS.
