Tips to make U disk install Apple system

Apple system has a problem and needs to be reinstalled. How to use U disk to recover? Here's how to install a Mac OS using a USB stick. First, prepare a USB flash drive of more than 8G, and there is a Mac OS installation CD. If there is no CD, you can use the image file. Second, enter the Mac OS, open the disk tool, format the U disk into the Mac OS extended format. Then select “Restore”. 3. Drag the Mac OS installation CD icon on the left to the “Source Disk” location and drag the left USB drive icon to the “Target Disk” location. Click “Restore”, the system pops up a warning and enters the account password to start making and installing a USB flash drive. The production process is quite long and takes about 20 to 30 minutes. The long wait for Mac OS to install the U disk has finally been successfully produced. Restart the system and press and hold ALT to bring up the boot menu. You can already see the icon of the Mac OS installation disk and select the icon to start installing Mac. Using a USB flash drive is faster than a CD, and the installation process is the same as using a CD.
