The next generation of OS X 10.7 Lion will only be released via the Mac App Store, which may sound cool, but it means that if you want to reload the system, you have to install 10.6 and then upgrade to Lion via the Mac App Store.
In fact, a mirrored file is hidden in the Lion installation package downloaded from the Mac app Store, and we can extract it and carve it out so that we can get a Lion installation disk. The steps are as follows:
Download Lion from the Mac app Store and you'll see Lion Installer in your Applications application folder when you're done.
Right-click Installer, and choose Show Package Contents, in the Open Finder window once into Contents > Sharedsupport, find a file named INSTALLESD.DMG.
Copy this DMG file to the desktop or something.
Use disk Utility or other burning software to burn the DMG file into a CD-ROM.
Of course, we are not sure that the future Lion official version can also be burned in this way, but I do not think the problem. In addition, Air users are very concerned about whether you can get Lion to the flash drive, interested readers can try.
