A new disk drive (named "update") appeared after erasing my disk and reinstalling Big Sur
Hello, I'm a new iMac user here. Literally. I am just able to afford an iMac system now and this is my first iMac ever after 3 years of saving. Which explains my newbie question. I hope you can help me. Anyway, here are my questions:
- Can someone tell me what the new disk drive is for? (see picture)
- Can someone help me understand what the contents of this drive are? (see picture)
- Is it save to eject this drive?
- Is it safe to delete the contents of this drive?
- If yes, how to safely delete the files?
A little history:
My iMac originally came with Catalina. So when Big Sur happened, I happily updated. However, to my surprise, the performance became VERY SLOW. The boot time is now at about 2 minutes and 30 seconds before I can fully use the Mac. The "hammer that drove the nail" was when I was having a zoom meeting with valued clients, and we were editing our documents and my Mac froze.
So I decided to reinstall the MacOs.
I did the "erase disk" procedure first, before reinstalling Big Sur. HOWEVER, the internet connection suddenly dropped and the installation failed.
So I performed an "erase disk" again and reinstalled the OS.
But the interface was sluggish so I decided to restart the Computer first and launch Recovery Mode again. To my surprise (I'm easily surprised), a rotating globe icon appeared and performed an internet recovery procedure. Cutting the long story short, I was able to install Mojave. When the installation finished, a new disk image appeared. It was named "update". When I updated to Big Sur, the disk drive was still there. I'm not so sure why it's there as it was never there before.
I appreciate any information on this. Thank you in advance! :)
