Ensure your Mac is connected to a stable internet connection. Restart your router or try connecting to a different network to rule out any connectivity 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: activate mac failed to create activation request
After these resets, boot to Recovery and retry reinstalling macOS (you may need to use Disk Utility to wipe the drive again).
Do not skip steps. Each solution builds on the previous one.
This error is extremely common on non-Apple hardware (Hackintoshes) or when running macOS in a virtual machine (like VMware or VirtualBox) without proper configuration. Ensure your Mac is connected to a stable internet connection
Sometimes, a simple restart can resolve the issue. Save any unsaved work, then restart your Mac and try to activate it again.
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. Reset SMC (System Management Controller) on T2 Mac:
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.
Rarely, the issue is not on your end. Apple’s activation servers occasionally go down for maintenance or experience outages.
