I'm happy with my Sierra (10.12.6), but the macOS downloads High Sierra in the background automatically and it takes over 5 GBs of my SSD. Every time I delete High Sierra image from Applications it keeps redownloading itself. How can I stop this madness?


System Preferences → App Store and disable ‘Download newly available updates in the background’.

  • I think it works only before macOS starts downloading the new update(s), because I ticked it off and yet I'm getting constant "Your disk is almost full", while this morning I had 3 GBs free. I'm 99% sure it's High Sierra, can I find the image somewhere? It's not in the Applications as it hasn't been downloaded yet. – Wordpressor Jan 8 '18 at 11:49
  • @Wordpressor You can find partial downloads in numerical folders located in open /private/var/folders/*/*/C/com.apple.appstore (run in Terminal). – grg Jan 8 '18 at 11:52
  • Thank you, somehow I run that command and the directory was almost empty but once I opened it it freed over 6 GBs on my SSD. Magic :) – Wordpressor Jan 8 '18 at 12:06
