Some hardware details may need confirmation.
Complete the missing hardware details
Import the matching system report first, or confirm the remaining specifications manually below.
Import a DxDiag file
This can automatically complete the CPU, RAM, GPU, dedicated VRAM, Windows build, display, and system-drive information.
dxdiag, wait for the scan, choose “Save All Information…”, then upload the saved TXT file here. The file is processed locally in your browser.
Enter details manually
Values imported from the system report are filled automatically and can still be corrected.
Known Apple configurations populate CPU and GPU core counts automatically.
Apple Silicon uses unified memory shared by the CPU and GPU. A separate VRAM value is therefore not requested. Clock speed is also omitted because CLO does not define a macOS GHz threshold.
CLO lists 10 GB free as the minimum and 20 GB free as the recommended target.
How the estimate works
The tool compares confirmed fields against CLO's April 2026 minimum and recommended requirements. Unknown information reduces confidence but is not automatically treated as a failure.
Your result
A simple comparison of your confirmed hardware with CLO’s current minimum and recommended requirements.
Readiness score is calculated from the official requirements for the detected operating system.
