![]() Specifies whether Apple Remote Desktop (also specified in System Preferences → Sharing) is started.Īfter rc has loaded in values from /etc/rc.common and /etc/hostconfig, it performs a check of the filesystem ( fsck) if needed. You can refine the crash reporter settings with /Developer/Utilities/CrashReporterPrefs. This corresponds to the SNMP startup item.Ĭontrols whether the crash reporter is started. Specifies whether the SNMP agent is to be started. This setting can be toggled using Windows Sharing in System Preferences → Sharing, which toggles the disable setting in /etc/xinetd.d/smbd. Older versions of Mac OS X used it to control Samba ![]() This corresponds to the Apache startup item. Ĭontrols whether the Apache web server (Personal Web Sharing in System Preferences → Sharing) is started. Although it’s not included with the desktop version of Mac OS X, you can download it from. Specifies whether the QuickTime Streaming Server is started at boot time. This setting affects the NetworkTime startup item. You can configure these settings with System Preferences → Date & Time. The NIS startup item uses this setting.Ĭontrols whether the network time daemon ( ntpd) is started. Leave it set to -NO- to disable NIS, otherwise set it to the appropriate domain. Specifies the NIS Domain that your Mac should participate in. The NFS startup item consults this setting. As an NFS client, a value of -YES- enables locking, but -AUTOMATIC- loads the appropriate daemons ( rpc.statd and rpc.lockd) so they are only used when needed. If your Mac is running as an NFS server, a setting of -AUTOMATIC- enables locking for NFS files. Specifies whether the Network startup item should turn on IPv6 support. ![]() However, this is not controlled by the Printer Sharing option in System Preferences → Sharing (that setting instead inserts the appropriate settings into the /etc/cups/nf file).ĭetermines whether the Network startup item enables IP forwarding. This corresponds to the PrintingServices startup item. The NFS startup item consults this setting.Ĭontrols whether Printing Services are started up. This corresponds to the AuthServer startup item.ĭetermines whether the NFS automount daemon should be started. Specifies whether the NetInfo authentication server for legacy clients ( /usr/sbin/tim) should be started. (For information on startup items, see " SystemStarter,” later in this chapter.) This corresponds to the AppleShare startup item. The settings in System Preferences → Network override this.Ĭontrols whether Apple File Sharing (Personal File Sharing in System Preferences → Sharing) is enabled. AUTOMATIC- causes Mac OS X to use the router supplied by DHCP or BOOTP. A setting of -AUTOMATIC- causes configd to use the value from the system configuration database. Instead, restart your Mac and boot from Tiger’s install DVD (hold down the C key as your Mac starts up), and then run the Disk Utility (Installer → Open Disk Utility) to repair a problem disk volume. Unlike with other Unix systems, we do not suggest that you use single-user mode to perform fsck repairs manually. Single-user mode should generally be used only to repair a system that has been damaged (for example, see " Restoring the Directory Services Database" in Chapter 5). In single-user mode, your filesystem is mounted as read-only, which limits what you can do. , hold down ⌘-S as you start the computer. To turn this setting off, use the command: sudo /usr/sbin/nvram boot-args= ![]() The next time you boot your Mac, it boots in verbose mode. Set your boot arguments to -v with this command: sudo /usr/sbin/nvram boot-args="-v" First, use the command nvram boot-args to make sure there aren’t any flags already set (if there are, and you didn’t set them, you probably should not change this setting). , you can specify a flag in the boot arguments that are stored in your system’s firmware. If you’d like to always boot in verbose mode If you’d like to see console messages as you boot, hold down ⌘-V (the “V” stands for “verbose”) as you start the computer. After a trip into Mach, the control bubbles up into the BSD subsystem, and eventually into the Aqua user interface.īy default, Mac OS X boots graphically. After the firmware initializes the hardware, it hands off control to the BootX loader, which bootstraps the kernel. When the computer is powered up, the firmware is in complete control. ![]()
