I’ve done csrutil disable and went into Terminal and put
cd /System/Library/CoreServices sudo mv Search.bundle/ Search2.bundle/
I rebooted and it removed the Spotlight icon from the menu bar but I could no longer use command-R to open Spotlight. I tried undoing via
sudo mv Search2.bundle/ Search.bundle/
but it returns
mv: rename Search2.bundle/ to Search.bundle/: Read-only file system.
Rebooted but still no functioning Spotlight. What can I do?
