When you buy a new Macbook device, there are several limitations in processing data that comes from outside the Macbook. One of them is that you cannot copy and paste data on the Macbook to an external HDD and vice versa.
The reason is that the external HDD format is different from the Macbook format (usually the external HDD is NTFS format, while Macs use a separate format, namely HFS + or Mac OSX Extended (Journaled)). To determine the exact type of your external HDD format, you can check it on the Application – Utilities – Disk Utility menu.
With the NTFS type, your Mac can only read but not write. For that, a third-party application is needed to open this access. Although this can be resolved by reformatting the external HDD so that it is the same as the Macbook format, the data that was previously stored on the external HDD must be sacrificed because it will be deleted as of a result of the reformatting process from the beginning. For example, with Fuse, X-Disk, Tuxera, and the like, the reformatting process can be carried out.
But how can we still access the external HDD on a Macbook device without having to reformat it so that the data stored is safe ?. One way you can do this is by installing Mounty which can be downloaded at https://mounty.app/.
Once downloaded, do the installation process. When finished, access the Mounty icon then click. A warning will appear: “Mounty” is an application downloaded from the Internet. Are you sure you want to open it ?. Choose “Open”.
Then the message will appear: “HDD EXT detected. Re-mount it read-write? ”. Select “Yes, sure!”.
After that, you will be able to copy and paste, delete, etc. on the data stored on the external HDD.
