💻 Error message appears when installing the Agent: no mountable file systems (for older macOS)


If you would like to install the Agent on an older macOS device (for example El Capitan), the following error message window will appear during installation:

The reason for this error message is that your older macOS cannot handle this dwagent.dmg file properly.

The dwagent.dmg file contains two files: the installer (DWAgent.app) and a pdf file (IMPORTANT_NOTES.pdf):

➡️ This means that you need to access this DWAgent.app in the dwagent.dmg file in a different way.

There are two possible workarounds for this situation:

  • In addition to your older macOS, you also have a newer macOS device.
  • In addition to your older macOS, you also have a different (Windows or Linux) system.

In addition to the older macOS, you also have a newer macOS device

On the newer macOS device, open the downloaded dwagent.dmg file (with double click on it).

The following window will appear:

Right–click on the DWAgent.app file. Click on the Copy in the pop–up menu. As seen below:

This copies the file to the clipboard.

Then right-click in one of the folders on your system. For example, in the Desktop folder. In the menu that appears, click Paste Item. As seen here:

This will copy the DWAgent.app file to the current folder.

➡️ After this, transfer the extracted DWAgent.app file to your older macOS.

You have several options to do this. A few examples:

  • using an USB drive (flash drive, external HDD, etc.)
  • use an email attachment
  • using a cloud service

➡️ On your older macOS, the Agent can already be installed.

✅ Once installed, our service works fine.

In addition to the older macOS, you also have a different (Windows or Linux) system

If you have another device that runs Windows or Linux, you can also use 7Zip to extract the DWAgent.app from the dmg file.

➡️ Using 7Zip, extract the DWAgent.app file to another folder on your system. You can see the steps here:

Launch the 7Zip application and open the dwagent.dmg file. Then right-click on the DWAgent folder, and select Copy To… As seen here:

The following window appears:

Browse to the folder where you want to extract it.

Then click on the OK button.

➡️ After this, transfer the extracted item to your older macOS.

You have several options to do this. A few examples:

  • using an USB drive (flash drive, external HDD, etc.)
  • use an email attachment
  • using a cloud service

➡️ On your older macOS, the Agent can already be installed.
