更新：Chrome 和 o3d 现在已是最新版本，但不确定它们是否正确更新，并且直到下一个版本才可以真正检查。
每当 chrome 或 o3d 尝试在我的系统（MBP、Mac OS 10.5.7）上自我更新时都会失败，我认为这是一个权限错误，因为我将我的帐户设置为 sudoer，而不是管理员。
我尝试手动更新（Chrome > 关于 > 立即更新），它会下载并安装更新的磁盘映像，但随后卸载它并显示消息“自我更新失败”。
关于如何找出问题所在，您有什么想法吗？
编辑：
我尝试在真实管理员帐户和完全非特权帐户上进行更新，结果相同。

答案1
您现在使用的 Chrome 是哪个版本？
在控制台中，它没有明确说明为什么中止下载http://dl.google.com/chrome/mac/GoogleChrome-3.0.192.0.dmg除了安装脚本失败之外的其他操作。您可以尝试手动下载更新作为一种解决方法，但听起来您的计算机上的 Google 更新引擎已损坏。您可以尝试重新安装 o3d，或删除 Google 更新引擎以强制重新安装。
为此，您可以
sudo /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py --uninstall从命令行运行：。
答案2
首先要做的是检查控制台/Applications/Utilities。Chrome 可能已记录有关该问题的消息。此外，您可以尝试将您的帐户设置为管理员并进行更新，看看是否有效。
/Applications编辑：您还应该使用 Finder 中的获取信息（⌘I）检查文件夹和 Chrome 本身的权限。
编辑 2：好吧，我唯一能得到的就是“ Return code 4 from an install script”。我不确定那会是哪个安装脚本，不过你可以尝试浏览一些应用程序包和互联网。
