Hi Spectal Ink,
On our Macs here, we routinely write to “/Library/Logs/DiagnosticReports” without issue… It may be different with the “via MacInCloud” workflow. Since your related post, Cannot upload to App Store - url scheme invalid has been resolved, I am concluding that this is a non-issue.
Let me know if you feel that this is still hindering your workflow and we will continue to investigate.
Thanks,
.
