Follow the steps below to boot from macOS Recovery and reinstall macOS on your Intel-based Mac.

  • Restart your Mac
  • When the gray screen appears, press and hold Command + R

7. Reset your Mac’s PRAM and SMC

If Mac error 102 appears due to hardware problems, the best way to solve it is to perform a hardware-based fix. For Intel-based Macs, you can reset the PRAM and SMC or System Management Controller. Before resetting the PRAM and SMC, make sure to back up all your data to an external hard drive. You will lose all this data after the reset process. So the only way to get your data back is to restore from a backup after resetting the PRAM/NVRAM and SMC on your Mac.

Here are the steps to reset PRAM/NVRAM:

  • Turn off your Mac
  • press Hello button and press and hold Command + P + R until your Mac restarts
  • If the startup bell sounds twice, the PRAM and SMC are reset

To reset SMC, the steps are as follows:

  • Turn off the computer.
  • Unplug the computer’s power cord from both the wall outlet and the computer.
  • Wait 15 seconds.
  • Connect the computer’s power cord.
  • Wait another 5 seconds and press the power button to turn on the iMac

If you are using an Apple Silicon Mac, the SMC is reset every time you reboot the system. For Non-Volatile RAM (NVRAM), there is no special command to execute the reset command. Several sources have said that NVRAM is reset every time the Mac is restarted from shutdown. This means that the memory is automatically reset in case of a problem.

It is. Following any or all of the steps above can resolve Mac error 102. Hopefully, you won’t see this annoying error again.
