Hello guys,
Everything seems works, but when I try to "Write" this error always happens: Error: Couldn't open /dev/disk2
The sd-card adapter is unlock. I have a Macbook Pro (Early 2015) running MacOS Catalina (10.15).
The only weird thing it's that when I chose the folder for th download, or chose the download file, and the LibreELEC needs to interact with Finder/iCloud Drive this Error appears too, but it does not prevent me from selecting the correct folder or file. 
I attached the relevant print screens.
Thanks in advance
