Check your Mac's settings to make sure the mirror will work properly

Q: My Mac is asking for access to Screen Recording. Should I allow that?

First, to ease your concerns, we don’t record your screen, and we don’t send any content to a server. We only temporarily store data in your device's memory before it is streamed to TV. Upon streaming, the content is removed from memory. So, it is safe to allow access to Screen Recording.

A: If you are using macOS 10.15 Catalina, you must allow Screen Recording in Privacy Settings. Read the step-by-step guide below.

The first time you click “Start Mirroring”, your Mac will show the following message:

Allow Screen Recording in Privacy Settings for Oka Mirror

Please click “Open System Preferences” and go to “Security & Privacy” -> “Privacy” -> “Screen Recording”. That's it! You're done. Now, open the app again and enjoy mirroring!

Note: If you click “Deny” on the first step, you must quit the Oka Mirror app and re-launch it. Next, find the “Open Screen Recording Preferences” button on the main screen, click it, then follow the steps until finished.

Click the checkmark next to the screen mirroring app you are using. When the screen mirroring app is opened, you will see this message; please select “Quit Now.”

Q: Why is there a 2 to 3-second delay when I mirror the screen?

This depends on your network performance. With current WiFi technology, there is no way to remove this lag.

Q: Why doesn't the app find the device 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 may help:

Click the left bottom icon on the app view, then choose Quit App. Relaunch the app after you do all the steps below.

  1. Restart your router. First, unplug it from the power source, wait 30 seconds, then plug it back in.

  2. Restart your device. Unplug it from the power source for a complete reboot. Please disconnect it from its power source for at least one minute, then plug it back in. Powering off your TV is NOT ENOUGH to do a complete reboot.

  3. Make sure that your Mac and the receiving device are connected to the same WiFi network, the same router, and the same router channel. Some routers (dual band) have a 2.4GHz and a 5GHz wireless network. So it’s important not to have your Mac on the 5GHz network and the receiving device on the 2.4GHz network (or the other way around).

  4. Use an AC or N router. New routers support Wi-Fi AC&N, whereas old ones might only support WiFi B or G. WiFi B & G are not up to modern networking tasks, so please use an AC or N router.

  5. 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

  6. You may have to follow a similar process with antivirus products, such as Norton. It’s essential as antivirus apps often have their firewalls and network traffic blockers. It’s easier to disable these apps while testing the connection fully, re-enable them and make adjustments later.

  7. The firewall on your router may prevent communication. Check that your router is configured correctly. Most home networks don’t need any particular configuration, but sometimes you may need to change a setting or two on your router to allow media streaming on your network.

  8. The device might not be detected if you use a VP. Please turn off VPN.

Q: My TV can be found but always fails on screen mirroring. What should I do?

If your system version is above MacOS 15.0, you should add the Oka mirror to the screen recording permission setting. See the first question on this page to find out how to do this.

Turn off the VPN if you are using one. Try to restart your Mac if it still doesn't 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 fails 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. 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 doesn’t have any sound during casting media files. What should I do?

A: In most cases, this failure is because your TV does not support the audio encoding of the media file. 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: My TV doesn’t have any sound during screen mirroring

A: For screen mirroring, you need to install the audio driver if you want to have sound. Get help from this blog.

Q: The sound of my TV is jumpy and stutters during screen mirroring. What should I do?

A: Mirroring the screen with sound consumes a lot of system resources. It will cause performance issues if your Mac model is too old. Please reduce the video quality and close other large apps when casting your screen with audio.

Q: Why can't I watch Netflix on my Mac and use screen mirroring simultaneously?

The error may be “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 exists on the Safari browser. When you use the Chrome or Firefox browser, the same content (in this case, “Designated Survivor” from Netflix) will play just fine. So, whenever you see this error message, please download and install Chrome or Firefox for Mac and use one of those two browsers to watch Netflix.

Q: Why can't some apps be cast or some DVDs or movies be cast?

Some apps block Screen Mirroring. This means application developers can choose 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 they also block screen mirroring when watching DVDs or iTunes Movies.

Q: How do I quit the Oka Mirror app?

Click the left icon of the app view, then choose Quit App.
