How To Fix MacOS Sonoma Could Not Be Verified?
To fix MacOS Sonoma could not be verified, you can check your internet connection, restart your mac, and check the system date and time. Additionally, you can boot into safe mode and install, and run the installer.
1. Check Your Internet Connection
A stable internet connection is crucial for downloading and verifying macOS updates.
An intermittent or slow connection can cause the update to fail verification.
- Ensure that your Mac is connected to a reliable Wi-Fi network.
- If you’re using a wireless connection, try moving closer to the router or using a wired connection instead.
- Try pausing other internet-heavy activities during the download and verification process.
- Restart your router and modem, unplug your modem and router, wait at least 30 seconds, then plug in the modem first, wait another 60 seconds, and plug in the router last.
2. Restart Your Mac
Sometimes macOS updates can fail to verify due to temporary software glitches or issues during the download process.
A restart can clear the system’s temporary cache, stop hung processes, and give the system a fresh start, which might eliminate the verification issue.
- Click the Apple menu in the top-left corner of your screen.
- Select “Restart” from the dropdown menu.
- If any open documents have unsaved changes, you will be prompted to save them.
- Wait for your Mac to shut down and start back up automatically.
3. Check The System Date And Time
Incorrect system date and time settings can interfere with the verification process of the macOS installer.
- Open “System Preferences” from the Apple menu.
- Click on “Date & Time” and unlock the padlock, if necessary, by entering your admin password.
- Ensure that “Set date and time automatically” is checked, or manually set the correct date and time.
- After correcting the date and time, attempt to install the macOS Sonoma update again.
