Source-checked About 10 minutes
Answer
Verify storage and internet access, check Apple System Status, restart the download, then use Safe Mode or macOS Recovery if Software Update still fails.
Check service, power, and space
Connect power, use a stable network, check Apple System Status, and keep enough free storage for the update.
Retry Software Update
Restart the Mac, open System Settings > General > Software Update, and retry without a VPN or captive portal.
Use Safe Mode
Start in Safe Mode and try the update again if login items or security software may be interfering.
Use Recovery only if needed
Install macOS from Recovery without erasing the disk when normal Software Update repeatedly fails; back up first.
