Does C-Pen work with MAC OSX Big Sur?

Short answer: YES, just follow normal instructions.

If there are notifications about malicious software or unidentified developer (because not being distributed via AppStore) go to System Preferences\Security and Privacy.

  1. TS1 (G2): use C-PEN Core software for MAC OSX and follow normal instructions.
  2. Connect: use Connect Desktop (MAC) and follow normal instructions.
  3. ReaderPenReaderPen Secure and LingoPen: no software required. Connect via USB and select Keyboard or U-disk on device screen. Check THIS video.
Text is not scanned

This article applies to C-Pen Core and Connect Desktop installed on MAC OSX.


If software is installed properly and the scan light turns on as supposed but no text appears in your app – check these things…

  1. In System Preferences\C-Pen Core settings make sure that Enable Input Method and Text to cursor checkboxes are checked.
  2. In System Preferences\Security and Privacy and the Privacy tab, locate and click on Accessibility service. If C-Pen Core or Connect Desktop is not listed among “apps allowed to control your computer” or in the list but not checked, then add/check the app. To add an app you need to click on the lock at the bottom of the window to open it (password required). When the lock is open, click the + sign, locate the app and select it to add. C-Pen Core is located in /Library/Input Methods. Connect Desktop is located in Application folder.

If all seems to be in order, still try to click/toggle the check boxes and reboot. This especially applies if you have had previous versions of either of the apps installed on your MAC.

App can’t be opened because Apple can’t check it for malicious software

Does MAC OSX refuse installation?

You get error message “[App] cannot be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information” or a reference to “unidentified developer“.

Normally this is caused by Privacy & Security settings of your system. To get past it, follow information in THIS article

Connect Chrome extension

Connect Chrome extension is OS independent and runs on Chrome web browser.

Connect Chrome extension is installed from Chrome Web Store. Once installed it opens as a (left side) panel in the open tab and uses Chrome’s built-in Bluetooth services to connect to the C-Pen Connect.

The extension is OS independent and nothing is required to be installed locally on the computer.

Connect Chrome extension can be used for multiple purposes; assistive reading, productivity and collaboration.

It can be set up to read scanned text out aloud, either automatically or when prompted. It is easy to use side by side with online collaboration services like e.g. Google Doc, MS Word online, OneNote and Evernote and is a perfect tool to boost productivity.

This is how it works…

Connect Desktop (MAC)



Connect Desktop app

Aside from C-Pen Keyboard functionality (scan text to cursor position), the Connect Desktop app also features Text Reader and Scan to File functions. Text can be set to be read out automatically or only when prompted to. It is possible to listen to full/multiple sentences and paragraphs or a single word. One time or repeatedly, as required. Scanned text can also be saved to text files and retrieved at a later point in time and re-listened to. A nice feature to support learning.


Download Connect Desktop app 

After download, open the .dmg file. To install, drag the Connect Desktop icon onto the Application folder icon.

Enable C-PEN Keyboard

The keyboard feature allows you to scan your text into other apps than Connect Desktop. Apps like Word, TextEdit, Excel, etc.

To enable this, 

  1. Go to System Preferences/Security & Privacy and click the Privacy tab.
  2. Select Accessibility in the left section. To the right is a section called “Allow the apps to control your computer” that probably is dimmed.
  3. Click on the padlock symbol in the lower right corner to open it. You will be prompted for your MAC password. Enter it and proceed.
  4. Now, select the Connect Desktop checkbox.
  5. Click the padlock again to lock it.
