Dear All,
I hope you are all great.
I keep on experiencing failure when I would like to upgrade to MacOs Big Sur from catalina.

Please kindly help to resolve the issue.
Thanks and regards

I'm sorry to tell you this, but your internet connection was not stable enough to successfully complete the installation. Did you use Wi-Fi? Upgrade files and update files are just too large to successfully download via Wi-Fi reliably. Any data interruption or slowness will introduce corruption to the file and it either will not complete the download, will not install, or if it does, you can have serious problems. I recommend that you trash the old file and do a new download via a wired Ethernet connection. That will usually go just fine unless there is a problem with your router.

I would first check to make sure that you have enough space for the new OS to install.
