How to check your Mac's setting to make sure the mirror can work?
Q: My Mac is asking for access to Screen Recording. Should I allow that?
First, we don’t record your screen into files and we don’t send any content to a server. We only temporarily store data in the memory of your device before it is streamed to TV. Upon streaming, the content is removed from memory.
A: If you are using macOS 10.15 Catalina, you need to allow Screen Recording in Privacy Settings. Read the step-by-step guide below.
Once you first time press the “Start Mirroring” button, your Mac will show this message:
Please select “Open System Preferences” and go to “Security & Privacy” -> “Privacy” -> “Screen Recording”, Now it is done. Just open the app again and enjoy mirroring!
Note: If you selected “Deny” button on first step, you need to Quit Oka Mirror app and re-launch it again. Now you can find “Open Screen Recording Preferences” button on the main screen, press it then follow upon steps until finish.
Then click on the checkmark next to the screen mirroring app you are using, When you have the screen mirroring app opened, you will see this message; please select “Quit Now”.
Q: Why there is 2-3 seconds delay when I mirror the screen?
This is depended on your network performance. There is no way to remove the lag for this unless we have new Wi-Fi technology for router.
Q: Why the app doesn’t find my device that I want to stream to?
A: Please make sure that your receiving device (e.g. Samsung TV, LG TV, Chromecast, Roku TV, etc.) and Mac are connected to the same Wi-Fi network. If you have problems discovering your device, here are some troubleshooting tips that can help:
Click the left bottom icon on the app view, then choose Quit App. Relaunch app after you do all the steps below.
Restart your router. Just unplug it from the power supply, wait 30 seconds, then plug it back in.
Restart your device. Unplug it from the power supply for a full reboot. Please disconnect it from its power supply for at least 1 minute, then put it back in. Powering off your TV is NOT ENOUGH to do a full reboot.
Make sure that your Mac and the receiving device are connected to the same Wi-Fi network, same router, and the same router channel. Some routers (dual band) have both a 2.4Ghz and a 5Ghz wireless network. So it’s important not to have your Mac on 5Ghz and the receiving device on 2.4Ghz or the other way around.
Use an AC or N router.New routers support Wi-Fi AC&N,where as old ones might only support Wi-Fi B and/or G. Wi-Fi B & G are not really up to modern networking tasks, so please use an AC or N router.
In many cases the firewall on your computer may prevent the devices from communicating. Apple has provided instructions for allowing applications through the firewall. Consult the information here: http://support.apple.com/kb/ht1810
With antivirus products, such as Norton, you may have to follow a similar process. It’s essential as antivirus apps often have their own firewalls and network traffic blockers. It’s easier to fully disable these apps while testing for connection, then re-enable and make adjustments later.
The firewall on your router may prevent communication.Check out that your router is configured properly. Most home networks don’t need any special configuration, but sometimes you may need to change a setting or two on your router to allow media streaming on your network.
If you are using VPN, the device also could not be detected, please turn off VPN.
Q: My TV can be found but always failed on screen mirroring, What should I do?
If your system version is above MacOS 15.0, you should add Oka mirror to the screen recording permission setting, read the first question in this page.
Turn off the VPN if you are using one. Try to restart your Mac if it is still not work. In many cases the firewall on your computer may prevent the devices from communicating. Apple has provided instructions for allowing applications through the firewall. Consult the information here: http://support.apple.com/kb/ht1810
Q: My TV can be found but always failed on casting media file. What should I do?
A: In most cases, this failure is because your TV does not support the file format natively. Try to check the “Auto Transcoding” option on the Streaming tab in Oka Mirror and restart the playback. Enabling this option allows Oka Mirror to transcode the file on the fly when streaming.
Q: The TV don’t have any sound during casting media file. What should I do?
A: In most cases, this failure is because your TV does not support the audio encoding of the media file. Try to check the “Auto Transcoding” option on the Streaming tab in Oka Mirror then retry. Enabling this option allows Oka Mirror to transcode the file on the fly when streaming.
Q: The TV don’t have any sound during screen mirroring
A: For screen mirroring, if you want to have sound, you need to install the driver, find help in this blog.
Q: The sound of TV is jumpy and stutter during screen mirroring. What should I do?
A: Mirror Screen with sound will take up a lot of system resource. It will cause performance issue if your Mac model is too old. Please make video quality lower and close other large apps when casting screen with audio.
Q: Why I can watch Netflix on my Mac and use screen mirroring at the same time?
The error is like “Whoops, something went wrong…There appears to be a display problem. Please ensure your monitor is HDCP compliant and is not mirrored using Airplay.” This problem only exist on the Safari browser. When you use the Chrome or the Firefox browser, the same content (in this case “Designated Survivor” from Netflix) will play just fine. So whenever you see this error message appearing, please download and install Chrome or Firefox for Mac and use one of those two browsers to watch Netflix.
Q: Why some apps can not be casted, or why some DVD or movies can not be casted?
Some apps block Screen Mirroring. This means that application developers can choose themselves if they want to block Screen Mirroring. For instance, Netflix, Disney+ and Apple TV have decided to block this.
Apple has HDCP DRM protection for playing DVDs or iTunes Movies. This means that they also block screen mirroring when watching DVDs or iTunes Movies.
Q: How to quit the oka mirror app?
Just click the left bottom icon of the app view, then choose Quit App.
