Hi DTS Engineer, i cannot post the results of the terminal, i get only errors here :-) Unfortunately, it did not work, sorry :-( When you download the package above, you will find the ddi is missing in the package. I was forced to (re-)install Xcode due its update was broken by the last update (ddi installation failed there too). I tried any things i found ... reinstall, deleting caches and many more. The package seems to be missing - for most people.

Hi, thanks for your help :-) xcrun devicectl manage ddis update Host CoreDevice version: 506.6 Updating host DDIs at /Library/Developer/DeveloperDiskImages The following directories provided candidate DDIs: /Library/Developer/CoreDevice/CandidateDDIs /Applications/Xcode-26.2.app/Contents/Resources/CoreDeviceDDIs After cleaning and updating the installed host DDIs in /Library/Developer/DeveloperDiskImages are equivalent to the original set.
