· I have Roon running on MacOs CAtalina in an old IMAC 2013 that does no support Mac OS Monterey. Now I can't access Roon because de new realease does not support MacOs Catalina. How can I do make a backup of my library? I am planning to purchase a new Mac but I don't want to loose my roon library
You can install a stopgap version of Roon on Catalina, and then perform a backup.
One important note: this release requires macOS 12 or later on Mac, and on Linux requires glibc 2.27 or later plus OpenSSL 1.1.1 or later. If you missed our earlier announcement and want to check whether your system is affected, more details are available in this post.
For Mac users who are not yet able to update to macOS 12 or later, we’re also making a pre-update installer available as a temporary option. This version will not receive future updates or security fixes, and may become incompatible with current Roon Remote or ARC versions over time. You can find the installer here.
The way to proceed is to use the temporary installer for the Catalina-compatible previous release at the link above.
Moving forward, you can also use Open Core Legacy Patcher to update older Intel-based Macs to MacOS 12, which will enable you to use the newer Roon versions.
