When re-establishing this controller, most problems that we may have with our Mac are usually solved.

If none of these solutions worked for you, you should opt for a more aggressive measure such as resetting the system management controller (SMC). In the Preferences window that will open, mark the section that says ‘External disks’.In the upper corner click on ‘Finder’ and go to ‘Preferences’.In order to display these external storage units you simply have to follow the following steps: Although it is absurd by default, Apple hides the external storage units in the Finder surely to avoid creating many access that end up harassing. Sometimes the most basic solutions work best. In this way the hard disk will surely appear on your desktop to access it.Īlso from this software we can use to drag the icon of the hard drive or pendrive in question to the Dock to force the creation of the shortcut.Īctivate the view of external disks in Finder

If this does not work we can also click on ‘First help’ so that the software performs the appropriate checks in its operation. This means that for some reason the computer has not been able to mount it so we must select it and in the main panel at the top click on ‘Mount’. On the side it is possible to detect all the units that are connected but there are some that are light gray. This is a tool that shows us the information of both the internal hard disk of the Mac and those that are connected. If we observe that the device works normally either by seeing the LEDs or because we have tested it on another computer, we simply have to go to the native application ‘ Disk Utility’.

When these LEDs are flashing it means that the hardware works perfectly and the problem will be in our Mac. Obviously when we are facing a pendrive we cannot do this cable check but we can look at the reading and writing LEDs that are included.
