你好Stackoverflow社区。
试着通过下面的教程运行-这样我就可以学习如何编写驱动程序实用程序。

我正试图在我的构建生成的kext文件上运行kextutil。根据说明,我将其复制到我的临时文件夹。但我得到以下错误:
admins-Mac-mini:Debug admin$ kextutil -n -t /tmp/ssvac.kext
Skipping staging and system policy checks because not running as root, expect staging errors.
Kext rejected due to improper filesystem permissions: <OSKext 0x7f91d402f140 [0x7fff898b2cc0]> { URL = "file:///private/tmp/ssvac.kext/", ID = "myappleid.ssvac" }

我试着像这样修改权限/所有者:

admins-Mac-mini:Debug admin$ ls -lah /tmp/ssvac.kext/

drwxrwxrwt 7 root wheel 224B 19 Oct 08:08 ..
drwxr-xr-x 5 admin wheel 160B 16 Oct 16:37 Contents
admins-Mac-mini:Debug admin$ kextutil -n -t /tmp/ssvac.kext

不知道该怎么解决。如果你有什么建议,我会很感激的。
谢谢你,谢谢

My mistake was when I copied from the debug folder to /tmp/, I didn't use the -r switch. Now that I have, this is the error I'm getting:
admins-Mac-mini:Debug admin$ cp -r ssvac.kext/ /tmp/
admins-Mac-mini:Debug admin$ sudo kextutil /tmp/
Contents/ com.apple.launchd.GufwRL5Sf0/ com.google.Keystone/ powerlog/ ssvac.kext/

从
ls
输出中可以看到,kext实际上是至少包含一个Info.plist文件的目录,和代码签名信息。(以Contents
开头)通常它还包含一个二进制可执行文件。* 全部 * kext中的文件和子目录必须具有适当的权限,才能考虑加载kext。这意味着必须应用权限使用chown
时,* 递归地 * 使用-R
标志。我通常建议不要使用
chown
,而只是简单地将kext复制到临时位置(用于测试,在macOS 11之前)或/Library/Extensions
(从macOS 11开始,或在部署时,或者在测试kext的 Boot 时间行为时)* 作为 * 根用户,因为在代码/编译/加载/调试周期:字符串
