Something is preventing my Mac Mini (Mid 2011, core i5) from restarting. As as result, I cannot install updates. How can I find what is preventing the Mac from restarting?

If I have to restart to clear out the RAM or similar, what I have been doing is running the terminal command sudo reboot now but I cannot install updates this way. Thank you.

  • Will it shutdown? (sudo shutdown) If it can shutdown, then you can power it back up which will be, in effect a reboot.

  • It will not shutdown via the Apple menu either, no. May 19, 2017 at 0:06
  • ...all terminal commands work, but they don't allow me to install updates. May 19, 2017 at 0:06
  • Have a look at this article: macworld.co.uk/how-to/mac-software/…

  • Thank you, but I tried everything listed in the article already. How can I find what program is causing the issue? May 19, 2017 at 0:33
