1. My existing files won’t be compatible
While the file system on Mac hard drives is different than on Windows PC, the actual files on both systems are basically the same. Files can be moved from a PC to a Mac without issue.
Files can be transferred to a Mac using USB flash drives or external hard drives, CDROM’s, or over a network. If you’re already storing or backing up files from your PC onto an external hard drive, it can be plugged into a Mac’s USB port and files can be copied directly to the Mac. Macs also come with a built in utility called “Migration Assistant” that can automatically transfer your files, email, contacts, etc. to your PC as part of the Mac setup process.
