Yesterday everything was working fine. Today, when I turned on macbook, enter the password as usual and in 60-75% of loading bar - screen starts to turn off and on. When screen turned on again, there're still loading bar finished at the same amount of percent as it were before. So far, I have tried to:

  • Run Apple Hardware Test (no fault found)
  • Reset NVRAM
  • Reset SMC
  • Re-install macOS using Utilities
  • First Aid in Disk Utility (Everything's fine)
  • Turn off FileVault
  • Turn off Firmware protection
  • Verbose mode (This issue appeared: "IOconsoleUsers: time(0) 0->0, lin 0, LLk 1, IOconsoleUsers: GioScreenLockstate 3, hs 0, bs 0,now 0, sm 0x0")

    What should I do to solve this issue?

  • I'd try Try a safe boot. Shutdown your machine. Hold down the shift key. Poweron. The boot up will take longer than normal because the filesystem on the startup drive is being checked and repaired as needed. All about safe mode including what features and apps safe boot leaves out. Safe boot uses a software driver instead of using your machines video hardware. support.apple.com/kb/ht1455 – historystamp Jun 8 at 19:01
