Safe Mode for X?? Anybody know about this? |

While trying to get a new hard drive with a new ide card to boot a cloned startup volume, I was having problems getting X to boot on the drive. Tried to reload extensions to no avail. Booted into single user mode and it froze after identifying the card and the volume. I couldn't get it past that point and could not type anything. I wanted to get back to 9.2 so that I could boot to the working volume of X on a scsi drive but didn't want to disconnect drives and stuff so I did the 3 finger salute to restart and then pressed "shift/option/command/delete" which in 9.2 will tell the computer to start from an external source. Well, it didn't this time. Instead, the computer booted into "Safe Mode" and started off of the ide card and ide drive. Unlike safe mode on a windows machine, everything seemed normal. Speed and mouse actions were normal. Everything was as it should be but I had this "Safe Mode" on the screen when the desktop first appeared. Figuring "what the hell?" I restarted as I normally would and the ide drive booted X just fine, no safe mode on the screen. Was this an accident? What is safe mode in X? Why would this "fix" the booting problem, or was that just a fluke? Is safe mode for X used for the same reasons as for Windows? Here is hoping that some of you people that really know Unix can answere this. The Help files in X don't say anything about Safe Mode or at least I couldn't find anything. |

Here is a bit more info directly from the link I posted....enjoy! :-) A Safe Boot is a special way to start Mac OS X 10.2 or later when troubleshooting. Safe Mode is the state Mac OS X is in after a Safe Boot. Starting up into Safe Mode does three things to simplify the startup and operation of your computer: It forces a directory check of the startup (boot) volume. It loads only required kernel extensions (some of the items in /System/Library/Extensions). It runs only Apple-installed startup items (some of the items in /Library/Startup Items and /System/Library/Startup items - and different than login items). Taken together, these changes can work around issues caused by software or directory damage on the startup volume. |

So jseibyl, the Safe-Mode is essentially the equivalent of Extensions Off in OS 9.X |

http://docs.info.apple.com/article.html?artnum=107392 This should answer your questions. Esentially it disables all third party extensions, and is used for diagnosing problems. |
