Dear all,
We are dealing with an issue ROOT has with the latest stable macOS version, 15.4, and XCode 16.3.
We are working to a proper fix, and made quite some progress already. However, at the moment, there is no ROOT released version that works on that platform - only the main branch.
Therefore, if you plan to update to Sequoia 15.4 and XCode 16.3 right now, you’ll have to build ROOT from sources.
Once the fix propagates to the 6.34 and 6.32 branches, 6.34.08 and 6.32.12 will be released and will propagate to the usual channels leading to binary packages.
Best,
Danilo
