Mac storage is inaccessible in the software: How to solve the problem

In the general run of things, if an operable storage device is properly attached to the computer, it instantly appears in the list of connected storages found in the left-hand pane of the UFS Explorer main window for subsequent access, analysis or recovery of lost files. However, the users of Macintosh laptop and desktop machines often face a confusing problem when a drive which keeps the data to be restored is simply not accessible in the program’s interface. The software may not be able to work with macOS drives due to several typical issues, effective solutions to which are given in this article.

Lack of administrative privileges

Administrator rights are required for any data recovery tool to work with physical drives, thus, the absence of the latter will certainly prevent UFS Explorer from accessing any storage device connected to the Mac, except for disk images or virtual disks which are not in fact real storage systems.

In this case, as long as you have an administrator password, you need to:

  • log into an administrator account;

  • restart the application with administrative privileges by entering the correct user/ password.

The following video tutorial shows how to run the software with elevated privileges from either an Administrator or Standard user account:

System Integrity Protection is enabled

In macOS 10.13 High Sierra and later a special security feature called System Integrity Protection (SIP) keeps third-party software from gaining access to the system disk. In essence, its role is to avert any modifications to system files performed by viruses and other malware and thus preserve the integrity of the OS and ensure its normal functioning, however, along with that, it doesn’t allow useful applications like data recovery tools to read the startup drive (Macintosh HD or Apple SSD).

Therefore, if you have one of the latest macOS versions and want to restore some files that have been lost from the drive on which the system is installed, you need to go one of the following ways:

  • disable SIP manually;

  • connect the drive to another computer as a secondary disk;

  • boot your Mac using Linux Live CD (this option requires a Linux license of UFS Explorer).

Otherwise, UFS Explorer won’t be able to access this disk, even when run with administrator privileges.

-To deactivate System Integrity Protection in High Sierra and later you may follow these simple steps:

  • Step 1. Restart your Mac (open the menu and choose Restart).

  • Step 2. On startup, press and hold the Command + R keys. This will make your Mac enter the Recovery Mode.

  • Step 3. In the Utilities menu choose Terminal to launch the Terminal application.

  • Step 4. In the command line window type in csrutil disable and press the Enter key.

  • Step 5. For the changes to take effect, restart your Mac again by clicking the Apple logo and selecting Restart.

-To make sure that SIP is indeed off after the restart, you may:

  • Step 1. Open the Terminal from the Utilities on the top of your Mac.

  • Step 2. Type in the csrutil status command and press Enter.

After that, you can run UFS Explorer and scan the drive for lost data. Having finished the recovery procedure, don’t forget to turn the SIP feature on by booting into the Recovery Mode again and typing csrutil enable in the Terminal.

Watch this video instruction which demonstrates the whole process step by step:

- In order to connect the drive to another computer as a secondary disk, you will need to take it out from the current machine and use a hard drive enclosure to insert it into another machine.

Disk connection or health problems

If the above give measures don’t help and the drive remains inaccessible anyway, the storage is likely to have physical or connection issues which are required to be handled to make data recovery possible.
