Your Mac can read the HFS+, NTFS, Fat32, exFAT and ext2 file systems. It’s possible to format from a mac with a USB to SATA cable which is on its way from eBay, but right now, the computer i have has one SATA connection and it doesn’t like the unformatted drive - even when booting from the ‘Install OS X Seirra’ USB drive. You'll see the MacOS Utilities window choose 'Disk Utility.' Now you can choose to erase your startup drive, and choose 'Mac OS Extended (Journaled)' as the operating system. You can use the built-in Disk Utility to format your drives to ensure compatibility. To get around that problem, hold down the Command + R keys when you turn on your Mac and let go when the logo appears. If you want to format your Mac's system drive, you can't do that when the Mac is running normally because the drive is in use by the operating system. Usually, you'll want ExFAT, which is the default for the MacOS. Select the drive you want to format and then choose “Erase.”Ĥ. At the top of the window, click 'Erase.'ĥ. In the pop-up window, choose the file system you want to use.
