Final Thoughts

The iMac won't turn on or won't boot past the Apple logo because the iMac verifies hardware connections and crosschecks the CPU, GPU, RAM, and hard disk during startup, which can be faulty or malfunctioning, causing the issue.

The iMac installs the starting hard disk and its system partition, verifying the specifications are accurate, and displaying the Apple logo and a loading bar on the screen as it identifies the starting hard disk.

The iMac's unresponsiveness is caused by file system damage and software mismatch, which prevents it from booting past the Apple logo. This is because macOS takes over all software and hardware components, and if it can't retrieve necessary data or track some applications, it won't load.

If your iMac's files get deleted, it would be better to download a professional data retrieval software, Deep Data Recovery for Mac.
