Apple MacOS Sierra: New OS may force an automatic upgrade from your end; how to block this processreuters

Apple's latest MacOS Sierra a.k.a MacOS 10.12 full public version that was seeded across the world last month has been found to automatically force itself upon Mac computers. Various loyalists have already started comparing this process to Microsoft's Windows 10 OS update that also pushed users to automatically upgrade.

This automatic upgrade process, of MacOS Sierra can now be stopped manually. If you are a first-time user of an Apple Mac or are stuck at with not knowing what to do when OS Sierra is downloading automatically in the background, then check out the steps below in order to resort to disabling this automatic process:

Step 1: Find the Menu bar; here select the Apple-like icon form the left hand corner at the top.

Step 2: After Step 1, select System Preferences

Step 3: After you choose System Preferences, choose App Store

Step 4: After Step 3, you should encounter the automatically check for updates section. Here, deselect/uncheck Download newly available updates in the background

Step 5: Your Mac should automatically disable automatic upgrade to OS Sierra, and thereby stay on the current operating platform El Capitan et al

Do remember that the automatic upgrade to Mac OS Sierra takes place only if your Macs meet the recommended technical specifications. Apple has even seemingly stated that this process will be activated randomly on Macs across the world.

  • The terminal shows execution of this command, and a Done at the end indicates the successful completion of making your hard-drive bootable with El Capitan installer.

Step 6: After you complete the above process, you should delete MacOS Sierra before you can install El Capitan from the bootable installer.
