Last week, James Pinkstone wrote on his blog that iTunes Match had deleted 122GB from his music library. Last Friday, Apple confirmed the existence of the problem, but was not able to reproduce it in its facilities. So much so that Pinkman assures that Apple sent two engineers to your home to investigate what might have happened trying to reproduce the problem. These engineers were almost all Saturday at Pinkman's house and there were also video conferences with other engineers in the block to try to reproduce the failure.
Apple engineers plugged an external hard drive into Pinkman's computer and ran a special version of iTunes to try and reproduce the mass erasure of songs from iTunes. They spent most of Saturday testing and communicating with Cupertino during the process. On Sunday, one of the engineers returned to Pinkstone's house to collect data on his iTunes and Apple Music usage on Saturday night, hoping to find some correlation between his habits and the erasure of songs. But they found nothing.
Deleting songs from iTunes remains a mystery
Pinkstone says that in the hours that Apple engineers were at his house nothing was discovered and that it is a strange and difficult to recreate glitch because no pattern was followed. Some files were deleted, some were not, some were in one format, some were in another.
At this time, why these songs were removed remains a mystery. The good news is that it has been confirmed that iTunes 12.4 includes security measures that Apple promised at the end of last week, although these measures were not included in the list of novelties. On the other hand, in almost all software updates we can read that small corrections have been included and these security measures are among them.
