Since I’m certain that the version I updated is fine, and my English isn’t very good, I used a translator. If “Pretty Sure” is too strong a word, I apologize. ---

When you remove DJ Pro from your system be sure to check for any hidden files that may be lurking as they are not all removed during un-install process. I just happend to do this yesterday as I wanted a fresh start with my library and the System One Connected no problem. Search here - ~/Library/Containers/ ~/Library/Group Containers/ ~/Library/Application Support/ ~/Library/Preferences/ /Library/Application Support/ /Library/Preferences/ /Library/Caches/ File names - com.algoriddim.djay com.algoriddim.djay-pro-mac Algoriddim djay Or you can use the following terminal command - find ~/Library -iname “\*algoriddim\*” -o -iname “\*djay\*” 2\>/dev/null ---

@Nandor_Racz thanks for the photos, they help a lot. Your Mac is set to Hungarian, and Koder’s is set to Chinese. That’s the one thing your two setups have in common so far, so let’s test it properly on the MacBook. First, a quick check. Unplug every other USB device, leaving only the RS1 connected. Then open djay and look at **Source** on the RS1. If djay still doesn’t show up, try RANE’s language fix: 1. Quit djay and unplug the RS1. 2. Open **Audio MIDI Setup \> Window \> Show MIDI Studio** , select **Rane SYSTEM ONE** , and click the **–** button. 3. Go to **System Settings \> General \> Language & Region** and add **English (US)** as a second language. 4. Restart the Mac. 5. Plug in the RS1, open djay, and check **Source** again. If it still doesn’t work, please post a screenshot of the **Devices** tab in djay’s settings with the RS1 connected. @Koder thank you for the screenshots. They confirm Engine OS 5.2.0, djay 5.6.9, an active subscription, and Wired Accessories set to Always Allow. Since your Mac is set to Chinese, please try the same steps above and let me know what happens. ---

It still doesn’t work, and I’ve noticed that I can’t delete the “SYSTEM ONE” option in the MIDI AUDIO settings. I also tried changing the language settings on my iPad. ![ccc5f683cc9768b9eafedfbf286b6456](https://community-assets.algoriddim.com/original/3X/1/f/1f24a3c7e67cfcd2bf90d3772f28dfd16b2f2e97.jpeg) ![7569d0b5f7512bde6c55fed5934eebae](https://community-assets.algoriddim.com/original/3X/5/f/5f3c4390ea2ecb27a110d3e441bd2e89bec5b5be.jpeg) ![f205587f69f88b06637f76f7cf01f474](https://community-assets.algoriddim.com/original/3X/c/f/cfc06181209841326f3524d3f52762b706712eea.jpeg) ![49d62669457bfbf275c96e68fbc18547](https://community-assets.algoriddim.com/original/3X/9/b/9b3b9fd17580f10680d868bf07efda077dafe6a8.jpeg) [Previous page](https://community.algoriddim.com/t/rane-system-one-cannot-connect-to-djay-pro/43299.md?page=1) [Next page](https://community.algoriddim.com/t/rane-system-one-cannot-connect-to-djay-pro/43299.md?page=3)
