Plugable Microscope not working after macOS 10.15 Catalina? We can help!

Background

One of the biggest changes in macOS 10.15 (Catalina) is support for 32-bit legacy applications has been phased out. Catalina and future versions of macOS operating system support only 64-bit applications. (You can read more about this in our Catalina blog post and on Apple’s site if interested.)

As a result, if you’ve recently updated your macOS version to 10.15 (Catalina), you may have noticed that your 32-Bit applications no longer launch. The software we’ll be focusing on here is the 32-bit version of Plugable’s Digital Viewer, used by the Plugable USB2-MICRO-250X and USB2-MICRO-800X microscopes. The 32-bit version of Digital Viewer will show an error when attempting to run in Catalina, stating “Digital Viewer needs to be updated.”

Thankfully, we’ve been working on a solution! Just in time for Catalina, we’ve got an updated version of the Digital Viewer software which fully supports Apple’s 64-bit application requirements and includes several other usability improvements. Read below for step-by-step instructions on how to upgrade to this new version.


Step-by-step instructions are presented below. For those seeking a quick summary: we suggest uninstalling the current 32-Bit version of Digital Viewer on your Mac and restarting. After uninstalling and restarting, download Plugable’s 64-bit Digital Viewer software here and install: Plugable Digital Viewer v3.3.30.pkg.

Installation Instructions

Step 1: Uninstall the current 32-Bit Version: Go to your Applications folder, click and drag the 32-Bit version of the Digital Viewer into your trash bin, and delete it

Step 2: Download the new 64-Bit Package Installer, launch, and click “Continue” to proceed

Step 3: Click “Install” to begin the installation

Step 4: Enter your password, and then click, “Install Software” to continue

Step 5: You should receive this message about successful installation. Go ahead and restart your Mac

Step 6: After restarting, open up the new Plugable Digital Viewer application, and make sure to set the, “USB Microscope” as the default device in the Settings. Click “Apply” to save this change.

    I uninstalled the old file and installed the 64-bit program. In settings, the USB Microscope did not appear and could not be found. What have I done wrong?

      Hello Oksana,

      Thanks for reaching out to us! I am really sorry to see you’ve had this trouble with the microscope, and I am here to help. I’m sure you didn’t do anything wrong. Are you able to try the microscope on a different computer ot see if you get the same result? I understand if this isn’t a possibility to try.

      We should check the Privacy and Security settings to make sure the microscope is enabled. Please feel free to reach out to us directly at: support@plugable.com, and we’ll be here to help.

    Thanks for the updated 64bit version, however, I had saved files from the previous version and I cant find them. Any ideas are welcome.
    After installing, I had to plug the camera so the program could recognize the USB Camera option

      Hi Heidi,

      Thanks for your message! The default save location is typically in the Documents folder in macOS for each specific user in a folder named Plugable Digital Viewer or Digital Viewer. This setting is user-configurable via the Settings (cog wheel) menu. If you are unable to find this folder, please send a message to support@plugable.com with Ticket #310916 in the subject line and we would be happy to help!

      Thank you,
      Derek
