Reinstalling your own operating system is kind of like a standard task nowadays if you are using your computer(s) extensively. No matter whether you are using a Mac or a PC, your operating system is kind of like “aging” everyday…getting slower and slower until the point you can’t stand it anymore and decide to do a reinstall.
Also…sometimes it takes less time to solve a problem by reinstalling the system rather than taking your time to find the solution itself…although you won’t learn much…but at least you will get the job out of the way.
Reinstalling Windows should be easy because most people are PC users; when you have a problem regarding your installation, it shouldn’t be too difficult to find someone to help you…but what if you are using a Mac?
If you are using a Mac and you don’t know / not sure how to reinstall your Mac OS X 10.5 Leopard, please read on and I hope this tutorial will be helpful to you. The steps will also be translated into Simplified Chinese.
Please remember to backup everything on your Mac before you do a system reinstall…this includes the data on your Boot Camp partition (don’t worry about Boot Camp if you have never used it).安装Leopard操作系统之前请记得先备份好你的电脑上面的资料。
Note: The screenshots below are in reduced resolution, you can always click on them to get the actual size of the image.
Step 0: Insert the Leopard DVD into your Mac, and you should see:
第零步:插入Leopard安装光盘,你会看到:
Step 1: Go to System Preferences and click on Startup Disk:
第一步:打开System Preferences,然后再 点击Startup Disk
Step 2: This is what Startup Disk looks like before we do any changes; as you can see, the Hard Drive Icon is selected because we are using our hard drive as the startup disk every time we switch on our Mac:
第二步:从下面的截屏可以看出,在我们还没有做任何改变之前,Startup Disk里面的Mac OS X已被选中,这是因为我们每次开机都使用我们硬盘上面的Mac OS X系统。
In order to reinstall the system, we need to use the Leopard DVD to start up our Mac, so just select the Mac OS X DVD and click on the Restart button:
要重装Mac OS X Leopard,我们需要把DVD光盘作为启动盘。 用鼠标/键盘选中Mac OS X DVD光盘,然后按下Restart按钮。
Step 3: After a few moments, you should see:
第三步:电脑重启后,你会看到:
Just select the language that you are comfortable with. Mac OS X is a multi-language operating system, you can change your system language anytime. (of course, thats after you’ve installed your system)
你可以在这里选择系统的安装语言。 Mac OS X是一个多语言操作系统,在系统安装完毕后,你可以随时更换你的系统语言。
Step 4: If you’ve changed your mind and decided not to reinstall your system right now, you can always quit the installer:
第四步:如果你现在暂时不想重装系统,你可以在这里退出:
If you want to continue with the reinstall, please click on the Continue button.
如果你想继续你的系统安装,请点击Continue按钮。
Step 5: From the menu bar at the top of the screen: Click on Utilities -> Disk Utility:
第五步:根据下面的截屏,打开Disk Utility用程序:
The Disk Utility application will appear shortly:
Step 6: Select your hard drive from the left hand side and click on the Partition tab on the right:
第六步:首先在左边选中你的硬盘,然后点击右边的Partition标签。
As you can see, I have two partitions (Mac and disk0s3) on my hard drive:
从下面的截屏中可以看出,我有两个分区:
This is because I’ve used Boot Camp on my iMac. If you’ve never used Boot Camp before, you should only have one partition on your hard drive. (unless you have made some changes yourself)
这是因为我用Boot Camp的缘故。 如果你从来都没有用过Boot Camp的话,你应该只有一个分区。
If you only have one partition, please skip the following contents and go straight to Step 8 instead.
如果你只有一个分区的话,请跳过下面的内容,直接去到第八步。
If you are like me who have used Boot Camp before and now having two partitions on your hard drive…just change the Volume Scheme to 1 Partition:
如果你像我一样用过Boot Camp的话,记住把Volume Scheme改为1 Partition。
You can even change the Name and Format of the Volume if you like…I normally change the Name only and leave the Format alone:
这里你可以为你的新Volume改名字和格式。 我一般只改名字,不改格式。
Step 7: Just click on the Apply button when you are happy with the changes that you’ve made. (Do remember to backup everything first):
第七步:当你确定你的设置都无误之后,你可以点击屏幕右下方的Apply按钮。
Click on the Partition button when you’re sure that you’ve got nothing to lose:
当你肯定你已经备份好所有的数据后,请点击Partition按钮。
Here you can check out the status:
你可以在这里看到硬盘分区的进度:
Now quit the Disk Utility application:
现在我们关闭Disk Utility程序。
Step 8: Now you are back to the Welcome screen again…just click on the Continue button:
第八步:请点击Continue按钮:
Step 9: Click on the Agree button after you have read and agreed with the agreement:
第九步:如果你同意这份协议的话,请点击右下方的Agree按钮。
Step 10: Here you can choose where to install your Mac OS X 10.5 Leopard on. In our case, we don’t really have a choice…but just keep in mind that you can install your Mac OS X on all sort of locations. E.g. On your USB external hard drive.
这里你可以选择Mac OS X的安装位置。在这里我们只有一个安装位置可以选择。 当然,如果你有需要的话,你可以把系统装到自己的USB移动硬盘上面。
Step 11: Select your Hard Drive and click on the Options button:
第十一步:用鼠标选中你的硬盘,然后点击Option按钮。
Step 12: Here you’ll have 3 options regarding how the system is installed. In our case, the 1st and 3rd one makes no difference because we’ve erased everything already. However, if you are installing Leopard for somebody else and they haven’t backed up their data, you can use the 2nd option (Archive and install). I strongly recommend that you backup everything first before you do a system reinstall (regardless of which option you use)…life is like a box of chocolate…you never know what you’re gonna get.
第十二步:我们这里有三个选项。 因为我们一早已经把硬盘上面的东西都删除了,所以第一个和第三个选项对于我们来说都没有什么区别。
第一个选项:第一次安装Mac OS X(说明你之前用的是Tiger或者是更早的操作系统)
第二个选项:把旧的东西保存起来,然后安装系统。
第三个选项:把所选中的硬盘上面的东西都删除,然后在该硬盘上面安装Mac OS X.
The 3rd option probably suits most people if they haven’t used Boot Camp before:
Click on the OK button when you’ve made your choice.Click on the Continue button when you’re ready:
当你选择好安装选项后,请点击Continue按钮:
Step 14: You can click on the Customize button to customize your Leopard installation:
这里你可以自定义你的Leopard安装内容:
Here are the things you can add / remove:
你可以添加/删除打印机驱动,语言包之类的东西:
In my case, I only install a handful of languages:
以我为例,我一般只安装亚洲地区的语言包:
When you are ready with the customization, click on the Install button to begin the installation:
当你完成了自定义选项后,请点击Install按钮:
If you don’t have much time, just click on the Skip button to skip the DVD check:
如果你没空的话,你可以跳过Leoaprd安装光盘的检查:
You can check out the remaining time of the installation:
你可以在这里查看整个安装过程所需的时间:
Step 15: Click on the Restart button after the installation has completed:
第十五步:安装完毕后,请点击Restart按钮:

当然,我并不需要这项功能,所以我选择了第四个选项,然后点击Continue按钮。
If you don’t want to do that right now, you can click on the Different Network Setup button and click on the last option:
如果你不想现在联入网络的话,你可以点击Different Network Setup按钮,然后选中最后的那个选项:

如果你不想设置密码的话,你会看到:
Just click on OK if you insist not to use a password for your account.
如果你真的不想设置密码的话,请点击OK按钮。
Step 24: Here you can choose / take a photo for your account:
你可以在这里为你的帐户挑选一张图片,也可以用苹果自己的照相机自拍一张。
Step 25: Here you will have the choice of registering now or later:
第二十五步:这里你可以选择现在注册还是以后注册:

Dear David:
I am in plans to replace the HD on my MacBook Pro for a bigger one. The HD that came with the computer is a 120Gig and the one I plan to install is 320Gig. The computer came with Tiger (and I have the backups from Apple). In the box came Leopard also, which I installed I think as an update.
I read your instruccions above, and I understand them, but this computer is going to have a blank HD to start up. Please, let me know how to do this in this scenario and also If I can use the disk of Leopard directly or need to start with the installation with the Tiger disk that came with the computer. I ask you this because I am used to Windows and usually, the originals back up disk have all the drivers for the system as well as the Operating System. (This is in the case of Windows Systems, I do not know if a Mac system does not need this and if the Leopard has the drivers for the system. Please explain this to me because I am afraid to do this. Thank You for your attention. R.C.
Dear David:
The system was restored now, and is working beautifully.
Your instruccions were a lot of help, but the program installed almost automatically. Apple software is great for its simplycity.
Thank You so much for all your help.
Here, in Miami, Florida, you have a new friend.
Yours truly, Roman Cecilia
