Recently bought a Macbook Air and things have been fine until the latest automatic software update which isn't working.
The latest update is about " Command Line Tools for Xcode 12.4 and Xcode 12.5".
Everytime I try to update this the update looks like it's about to finish and install but then it loops back to start as if nothing has happened.
I don't really know much about coding or that kind of thing so I am unsure what to do
MacBook Air 13″, macOS 11.3
Shutdown Router. Shutdown computer and disconnect all External Drives. Restart Router. Connect to Router via Ethernet Cable. If via Wifi - Disconnect all other Devices using the Wifi - want the Maximum Bandwidth only for this computer. Restart computer in Safe Mode. It does a Repair Disk, Clear System Cache files and only load Apple Software, extensions and Fonts. Will load slowly - Normal. Once Logged in - open Apple Apps Store and Get the Full Version of Big Sur. It will take some time and several pauses will occur - normal. Countdown clock may say 15 minutes but in Real time may be 30 minutes. Same goes for clock at 10 minutes could be 20 minutes in Real time. Eventually , Full Installer will download and a New Application in Applications Folder will present called Install Big Sur. Stop there and perform a Time Machine Backup. If desired - have an External Drive - Copy & Paste the Install Big Sur Application to external drive for future usage - making a Bootable Installer. Now run the Installer.
Have found this method more reliable than the Software Update which is very iffy at best
Are there any AntiVirus, Disk Cleaner, Optimizers, Defrag, VPNs etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.

Thank you, the problem sorted itself when I restarted my mac.
Thanks
Hey there!
Can you say, or take a screen shot of where you see this update? Thanks!
Nice! If only it were that simple every time! Good to hear.
Mac won't perform latest update.
