You can sync My Blocks across sprites by dragging or duplicating the blocks.


14. I want to delete a customized role or costume on mBlock 5, but the operation is blocked by the computer housekeeper. What can I do?

When this happens, choose to allow the operation this time.


15. Why does my device fail to connect to mBlock 5?

Try the following operations:

1. The driver installation is blocked by the security software. It is recommended that you disable the security software during installation.

2. Use mBlock 5 of the latest version and update the device firmware.

3. For Windows: Double-click the mblock5/drivers/Driver_for_Windows.exe file in the root direction of mBlock 5 to manually install the CH340 diver. Restart the computer after installing the driver.


16. Local extensions cannot be upgraded or deleted. What can I do?

If an extension you added on your computer cannot be upgraded or deleted, perform the following operations:

For macOS:

Way 1:

Open the terminal and enter rm -rf ~/mblock/exts

Way 2:

(1) Open Finder. (2) Choose Go > Go to Folder. (3) Enter ~ in the dialog box that appears. (4) Expand the mblock folder and delete the exts folder.

For Windows:

(1) Open the directory C:\Users\{username}\mblock. (2) Delete the exts folder.


(3) Restart mBlock 5.


17. I cannot find my local projects in "My Projects" after upgrading mBlock 5 to V5.1.0.

Project management is optimized in mBlock 5 v5.1.0. Local projects are no longer shown in My Projects. Projects saved to computer can be found in the corresponding folders.

If you have saved your projects to a specific folder, visit the folder to find your local projects.

If you have saved your projects to the default folder by mBlock 5, follow the steps to visit the folder:

For Windows

Visit: C:\Users\{user name}\mblock\project

For macOS

1. Click GO -> Go to Folder, and enter ~


2. Go to mblock


3. Find local projects in the project folder


18. The system displays a message indicating that the version of the graphics card driver is too low. What can I do?

1. Visit http://html5test.com to see whether the browser supports webgl. If yes, go to the next step.

2. Check whether your computer supports the render engine of mBlock 5.

Visit the Scratch official website: https://scratch.mit.edu/

(1) webgl1:http://twgljs.org/examples/twgl-cube.html

(2) webgl2:http://twgljs.org/examples/uniform-buffer-objects.html

If neither of them can be visited, go to the next step.

3. Check the graphics card configuration of your computer.

Example: (Computer with improper configuration)

Compare the configure to the official blacklist of webgl. If the graphics card is in the blacklist, you need to change the graphics card and cannot use mBlock 5 currently. It is recommended that you use mBlock 3 temporarily. If the graphics card is not in the blacklist, go to the next step.

4. Update the graphics card driver.

Use Driver Wizard or other software, or download a graphics card driver, for example, at http://drivers.mydrivers.com/install/.

If the problem persists, it is recommended that you use mBlock 3.

19. A black screen is displayed after I open mBlock 5. What can I do?

Generally, this is because some programs on your computer have occupied large memory, causing other programs to run out of memory.

You can perform the following steps to open the resource monitor, view the memory usage, and close some programs that have occupied large memory.

For Windows 7

1. Open the resource manager.

2. Open the resource monitor.

For Windows 10

1. Open the resource manager.

2. Open the resource monitor.
