updating to MacOS 27

The M4 Mac mini asked to download 13+ GB and update MacOS to version 27, Golden Gate - upgrading from MacOS Tahoe 26.6. Since the office fiber internet was down, I hesitated to start the process using Airtel 5G - but since 5G is supposed to be unlimited on my plan, went ahead.

It took nearly 90 minutes to complete the whole update, probably because while downloading, the 5G network was dropping down to 4G and getting throttled due to exhausting today's quota. On 5G, the download was happening at 30-45 Mbps. 

Interestingly, even after the "Downloading" phase completed and the "Preparing" phase started, there was still plenty of downloading activity as seen in Activity Monitor app. "Preparing" took half an hour. Then 8 minutes on the Apple logo screen while restarting.
