OS X messed up the SSD by eating it.
on December of 2022, I came across another upgrade offer for MacOS High Sierra on the App Store. This time, it was for a discounted price. However, there are no reviews regarding the system on the page now (they used to be near each application that was provided for installation), the developers have now prohibited this possibility (supposedly, in order to avoid.). The reviews used to be near each application that was offered for installation. I started the installation because I was under the impression that Apple only sells software that has been tried and is guaranteed to work. After the restart, the message "Your computer is unable to install macOS." It would appear that the file /System/Installation/Packages/OSinstall. Mpkg is either missing or corrupted. Finish the installation to restart your computer, and then attempt performing the process again. Even after multiple restarts, neither the new nor the old version of OS X would start up. The actions that were recommended by Apple support also did not produce any results, and the laptop remains unable to appropriately display the SSD. We attempted it ourselves by means of a remote connection; nonetheless, the outcome was the same, and they suggested getting in touch with an authorized SC. The software installation was to blame for the fault on the disk, which the service center was unable to resolve. After another three weeks, the conclusion was "SSD replacement is required." The failure of the solid-state drive (SSD) was brought on by the installation of macOS High Sierra from the Apple Store. As a result, the MacBook was rendered inoperable and useless, and the user also lost all of the information stored on the SSD. I made the unfortunate decision not to create a backup, but I now see why Apple is so adamant about customers following their advice to do so.
After coming to the conclusion that replacing the SSD at my own expense would be both inappropriate (more than 40,000 dollars) and not fair for my agreement to use OS X, I once again contacted Apple Support. I was resigned to the fact that I would not be able to use the MacBook for an extended period of time and that all of the data that was stored on the SSD would be lost. The problem was reported to Apple Engineering, and after another two weeks, I was informed that it had been addressed. I was told that "Because the MacBook's warranty has expired, Apple does not intend to address this issue." He requested that I provide him with an official response, but I never got one from you. When further inquiries were made, support stopped responding to them.
