Error occurs when using L515 on Macbook
Hello,
Now I'm trying to use RealSense L515 on Macbook.
But it does not work well enough, so please give me advices.
At first, my environment is as follows.
MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)
macOS Big Sur 11.5.2
librealsense : v2.49.0
L515 firmware : 01.05.08.01
I built RealSense SDK following this page.
https://github.com/IntelRealSense/librealsense/blob/master/doc/installation_osx.md
After building by "make", I installed by "make install", then run "realsense-viewer".
In "2D" mode, when I turn on one of "L500 Depth Sensor", "RGB Camera" and "Motion Module", every data can be shown well. (Only RGB data has a delay about 0.3sec.)
When I turn on both of Depth and RGB data, the frame rate of Depth data becomes very small (about 3fps) or stops. (RGB data also has a delay about 0.3sec.)
When I turn on all of 3 data, every data can be shown well. (Only RGB data has a delay about 0.3sec.)
In "3D" mode, when I turn on both of Depth and RGB data, the application crushes.
When I turn on all of 3 data, it also crushes.
When I turn on Depth or Motion data, it does not crush.
And I found that it does not crush under these settings.
Depth : 320x240 30fps, RGB : 640x480 30fps
But I would like to use it in full specifications.
Best Regards,
Masashi Takahashi

Hi Kakitsubata0711,
This may be a cabling and port issue. Your MacBook Pro does not have any USB 3 Type-A ports. The L515 is validated only with the USB4 Type-C to A cable that is packaged with the camera.
To confirm this, can you test the camera on another computer that has USB 3 Type A ports and connect the camera using the cable that came with it?
The Thunderbolt ports may be powerful enough to drive the camera but the cable the customer is using may not support the bandwidth requirements.Sincerely,
Sahira

Hello Sahira,
Thank you for your comment.
I have tried the packaged cable with the camera.
MacBook has only Type-C ports, so I used the Type-C to A cable with a conversion connector.
Incidentally, this error does not occurs in Windows PC(XPS13 7390).
This PC also has only Type-C ports, so I used the cable, the conversion connector and the camera.
So I think that the error factor is not the hardware.
Best Regards,

Hi Kakitsubata0711,
Because the RealSense camera works on your other system with no issues, we can rule out the RealSense camera being the problem. This issue is probably due to the ports on your Macbook - perhaps it is not supplying enough power to the RS camera to function properly and at the highest specs. But the camera is not defective.
Sincerely,
Sahira
