小弟第一次直接upgrade成Leopard,一切沒問題,一直到今天手賤,按了一下軟體更新,
好像更新了一項"鑰匙圈存取XX"之類的東西, 問題來了,
重新開機後盡然就出現 歡迎頁,填入個人資訊等的畫面,填完之後按確定盡然
等了一下,又出現了歡迎頁,就這樣重複出現....當場快哭出來...
無奈只好重灌(因為實在有很多資料在裡面，所以還是沒把東西都砍掉重練),
灌完後還是卡在歡迎頁的地方,永遠跳不出來...
不知道各位有沒有碰到我類似的問題,裡面的資料還有的救嗎?.....

小弟第一次直接upg...(恕刪)
Safe mode: 開機噹聲「後」，按住Shift
參考文件：http://docs.info.apple.com/article.html?artnum=107393
如果你有啟用，那也可以使用最高權限的root登入，10.4跟10.5的方式不大一樣。

看板上有無高人可以幫你利用single-user模式刪除密碼登入？
single-user mode: 開機「後」，按住S，會進入黑底白字的文字指令模式

在Macfixit上有位苦主的狀況跟你很像，也是在軟體更新之後，出現無限迴圈的設定頁面。不過他比較好運，因為他住美國，打技術客服電話搞了一小時，終於搞定他的問題：
Needed 1 hour of Apple Care Tech Support to resolve an issue with this install.
After downloading the updates and the computer rebooting itself, I was sent to the Leopard Setup Assistant. I gave the set-up assistant a chance and entered the requested information. The process never worked and went back to its beginning even after saying it was done. Trying to migrate from Time Machine was to no avail -- the set-up assistant just didn't do anything. Even booting in Safe Mode just brought up the assistant. I tried booting from Disk Warrior, Tech Tool Pro and Drive Genius disks also with no luck restoring the drive.
Apple Tech Support used the Leopard Upgrade disk and Disk Utility to verify disk first, repair permissions second, and repair disk last. After rebooting in Safe Mode without Leopard disk in, I was brought to the login screen. Using the back button we found the restart button and engaged the process. At this point iTunes and Quicktime (through the Software Update program) began to finish its installation and rebooted again. Finally got back to Leopard.
Apple Care had no explanation and said they were unaware of any one else with this problem. My 24-inch iMac was bought the day Leopard was released and is a fairly clean system (as I did not migrate any files from my powerbook yet and have only installed two programs -Flip4Mac and Skype).

個人認為這次隨著10.5上市後釋出的那一堆更新，有點小狀況。個人猜測，這次釋出的iTunes 7.5有點小問題。Apple可能會再釋出一些更新吧？？
