Administrators Hervé Posted April 9, 2019 Administrators Share Posted April 9, 2019 Thread moved. Please don't post in the Guides section which is clearly labelled "Guides only, no support" ! Coming back to your predicament: your disk reports IO errors. You need to look into that, say with Disk Utility having booted your macOS USB installer. kernelcache/PrelinkedKernel is reported as needing rebuild right before your system hangs. If your disk LED is showing activity, wait several minutes for this rebuild to complete. Failing that, try and boot your USB installer and deletes the cache + PrelinkedKernel folders from Terminal.
