Good morning guys … I read with regret that you also had this problem … I unfortunately do not have time machine activated so I can not recover the file to replace … and as maxon says I can not reinstall 10.14 because having a mac pro early 2009 is not compatible … it is a big problem this!
Then yesterday panicked I deleted the entire folder itunes and I hope that this does not create more problems!!!
If you have other solutions I would be happy to read them…
