i can't to do update my macbook air m2 to macos 15 sequoia i have error

If an error occurred while updating or installing macOS - Apple Support

Too many other people downloading at the same time and Apple Severs are overloaded

Software on the computer interfering with the download process including AntiVirus Software

Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.

Running behind a VPN which may increase Packet losses or corruption of the download 

If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer. 

Best Results are via Ethernet Cable to Router

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal and Try Again using the Software Update Applet in System Preferences

Worst case - Restart in Recovery Mode and choose Reinstall macOS. This in theory will pull the latest version of Sequoia available and commence the installation.

1. Turn off find my mac in iCloud settings.
2. Install the update

Just try turn off "find my Mac" on iCloud settings and go to updating again it works for me I manage to download Sequoia 15 but find my Mac needs to be disable...

Did you solved that? I went to apple store they told me to come back in month time and they will try to solved if can't update.

This worked! Thank you.
