This should restore the version of OS X originally pre-installed on the computer. Physical Description As shown in figure 2, the My Passport drive has: A USB 3. If you want to use the drive with a Mac computer, see Reformatting the Drive and Troubleshooting. I suggest using Ethernet if possible because it is three times faster than wireless. Your My Passport drive is formatted as a single NTFS partition for compatibility with all updated Windows operating systems. Note : You will need an active Internet connection. Be sure to select the correct drive to use if you have more than one.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Click on the Options button, set the partition scheme to GUID then click on the OK button. So if you want to use USB 3 you need the silver Mac version.
However the same rules apply, only PCs with this software will see drives formatted for Macs.First thing to do is update Yosemite.
Otherwise, you can have a drive as NTFS to allow to work on any PC and then install on your Mac a free app from the Apple website called NTFS-3G, which allows your Mac to fully use (read and write) to NTFS and also do automatic backups with no restrictions on both systems, but since it is done using the NTFS-3G software, this configuration will only work on YOUR Mac and the others will only read from the drive (But they won’t be able to add files).Īlso, you can have the drive as HFS+ to allow you to use it on any Mac and then install on Windows a program called HFSExplorer (Free), which allows you to read (see and copy out) drives formatted for Mac (But not write, so you can’t add files) or you can install MacDrive (NOT free), which is a software able to allow full HFS+ integration (Read and write) on a PC, meaning that it is the exact opposite to NTFS-3G. You can format a drive as FAT32, which would allow it to work on BOTH Windows and Mac, but it won’t do automatic backups, won’t take files larger than 4GB and will have a high risk of data corruption
