Step 2: Copy important documents
This copy includes everything from the Documents folder ( Macintosh HD Users Documents account name ), to desktop items, other important folders on your Mac. You need a little time to find through all your folders to make sure you don't miss it. Then drag and drop all of them to an external hard drive. If using Apple Mail, save your email files by copying the Mail folder ( Macintosh HDUsers LibraryMail Account Name ).
Step 3: Transfer Media
This is a three-step process. First, transfer your music collection. If you listen to all the music in iTunes, copy the entire iTunes folder ( Macintosh HDUsers MusiciTunes account name ).
Next, transfer your iPhoto library. To save your iPhoto collection, copy the file titled "iPhoto Library" ( Macintosh HDUsers Account name PicturesiPhoto Library ). If all your photos are not in iPhoto, you need to check if there are any pictures in the Pictures folder ( Macintosh HDUsers Pictures account name ) or videos in the Movies folder ( Macintosh HDUsers Movies Account name ) ; If there are files in it, copy them to an external hard drive. You should do this step in your free time because your media files are usually the largest of all the files to copy, and so they will take a long time to copy to an external hard drive.
Step 4: Transfer settings and Bookmarks
Do not forget to save all settings and preferences that are set on your device. Usually, they take the most time to re-create, so saving is the best way. The best way to save your settings is to synchronize your preferences with .Mac. To access .Mac Sync, open System Preferences and click .Mac. From here, select Sync in the toolbar and select the preferences you want to sync.
And with Apple's new MobileMe service, you can fully sync your email, so you won't need to copy your Mail folders as described in step 2.
Save browser bookmarks :
For Safari users : Open Safari, click File , then Export Bookmarks , and save the file to an external hard drive. If you have a .Mac account, you can use it to sync. In Safari, go to Preferences | Bookmarks , then tick Synchronize my bookmarks section using .Mac .
For Internet Explorer users : If your system is old enough to have Internet Explorer installed, back up your Favorites. There is an Export Favorites option in the File menu but it is grayed out. To activate this option, you must click on the Favorites tab in the bar picture on the left, then click the Organize button above and select Open Favorites Window . Now go back to the File menu and select Export Favorites , save the file to an external hard drive.
For Firefox users : Click Bookmarks , then Organize Bookmarks . When the Bookmarks window appears, click File , then Export . , and select the external drive as your destination.
For users Opera : Click File | Import and Export | Export Opera Bookmarks .
Step 5: Use Screenshots for the rest
There are a few things that you can't save in a folder and copy to an external hard drive: especially about the look and appearance of Mac - the aesthetic sense you've arranged and arranged according to your preferences. It is also possible that you have files on the Desktop that have been arranged in a specific way, or that certain applications are organized in a specific order. These things are not really important but there is no reason to lose them. So what's the solution? Capture those by using screenshots for anything you want to reconstruct after installing new Mac OS X. You can easily follow this action by holding and pressing Sim-Command-3 simultaneously. to show the complete screenshot or Shift-Command-4 to select exactly what you want to capture.
Part 2: Reinstall Mac OS X
When the external drive contains all the necessary data, this is when you reinstall the operating system. This step will take about 30 to 90 minutes, depending on the speed of the processor. The installation is simple, just insert the DVD installation disc into the drive and follow its suggestions. Therefore, we will not give detailed instructions on this installation process.
Part 3: Data recovery
Restoring your files is the same as saving them, but the opposite is true. There are two exceptions: to restore Safari bookmarks, you need to open Safari, click File , then Import Bookmarks , point to where you exported them. In Firefox, go to Bookmarks | Organize Bookmarks . , then File | Import . ; and in Opera, File | Import and Export .
To restore your email, open Apple Mail, click File , then Import Mailboxes . From here, choose to import data from " Mail for Mac OS X " and select the Mail folder. Your mail will be automatically imported into the new folder called " Imported ". To transfer messages to the main mailbox, you just need to mark all messages and drag them to the correct mailbox.
That's all you need to do to improve the situation for your computer. These operations can take part of your afternoon, but by the end of the day you will find it interesting to have a new Mac that is twice as efficient as the previous state.
