Question: macos High Sierra freeze


After upgrading to mcos High Sierra I have been experienced unpleasant freezing which I have never seen before. It usually happens when I am surfing in Safari and witching between multiple tabs, at some point the screen completely freezes and nothing moves anymore, the loading thing shows up instead of the mouse pointer and I have to waiting for 5 solid minutes before being able to control my mac again. What could be the problem? I have already tried to format everything completely but not much was achieved, I still have the same problem as before.

There are some troubleshooting steps to follow, in no particular order:

Needless to say, if you are using any non-Apple "anti-virus", "cleaning", or "Internet security" products, anything at all in that broad category of utterly useless garbage, don't. A lot of things won't work if you do.

If you don't get anywhere, you can use the following procedure to determine if the problem is internal or external to your Mac. Causes may involve your router, your ISP, the DNS Server(s) it uses, or certain user-configurable options.

  1. Shut down your Mac.
  2. Load macOS Recovery by holding and r (two fingers) while you start your Mac with a third finger.
  3. At the macOS Utilities screen, release those two fingers.
  4. Choose Get Help Online.
  5. Safari will launch, but it will lack your bookmarks, favorites, history and other preferences.

Determine if the problem persists while using Safari in that mode. After that, restart your Mac normally, and reply with your observations.

Back up your Mac prior to making any changes to its file system. To learn how to use Time Machine please read How to use Time Machine to back up or restore your Mac - Apple Support.
