Ensure your Mac is connected to the internet. An active internet connection is required to create an activation request. If you're using Wi-Fi, try connecting via Ethernet cable directly to your router.
Before diving into fixes, it is crucial to understand what this activation step is and is not.
This process, introduced around macOS Catalina, primarily affects Intel-based Macs with the T2 Security Chip (2018–2020 MacBook Air, 2018–2020 MacBook Pro, 2019–2020 Mac Pro, 2018–2020 Mac mini, iMac Pro, and 2020 iMac). When you reinstall macOS, the T2 chip contacts Apple to validate that the Mac hasn’t been reported lost or stolen and that the hardware is genuine.
The error “failed to create activation request” means the T2 chip either cannot build the encrypted request packet or cannot send/receive a valid response from Apple.

The "Failed to create activation request" error typically occurs during a factory reset or after a software update when the Mac cannot communicate with Apple's activation servers. Immediate Solutions
Verify Internet Connection: Ensure your Mac is connected to a stable network. If Wi-Fi is failing, use an Ethernet cable and a hardwired connection to bypass potential wireless interference.
Check Date and Time: Inaccurate system time can block communication with Apple's servers. You can manually update the date and time using the Terminal app in Recovery mode.
Restart the Device: Hard restart by holding the power button until the Apple logo appears. This can sometimes clear temporary glitches in the activation process. Advanced Troubleshooting Ensure your Mac is connected to the internet
If basic steps fail, users in the Apple Community and on Reddit suggest these deeper fixes: Erase Mac via Recovery Assistant:
On the "Activation Failed" screen, go to the top left and select Recovery Assistant > Erase Mac.
The device will reboot; connect it to Wi-Fi and wait roughly 10 minutes for it to attempt activation again.
Revive Firmware: If you have a second Mac, you can use Apple Configurator to "Revive" (not restore) the firmware. This allows the second Mac to handle the activation request for the failing one. Incorrect date and time settings can cause activation issues
Remove Activation Lock: Confirm the device isn't still linked to an Apple ID. You may need to remove the device from Find My on another device before it can be reactivated. Known System Issues
Though Apple downplays these resets for T2 chips, they still help clear network and activation caches.
Reset NVRAM (non-volatile RAM):
Reset SMC (System Management Controller) on T2 Mac:
After these resets, boot to Recovery and retry reinstalling macOS (you may need to use Disk Utility to wipe the drive again).
