Safari uses much less memory under macOS High Sierra

Kirk McElhearn:

It’s time to tip a hat to Apple for a major change they’ve made in their latest desktop operating system, macOS High Sierra. Last year, I wrote about how Safari was a memory hog. At times, it would be using 5,6, even 8 or 9 GB of memory. I would have to quit it every few days to get it to stop being sluggish.

Since the release of High Sierra, I have noticed that Safari’s memory usage has dropped a great deal. Right now, with my iMac running for more than four days, Safari is only using about 3 GB of RAM. And this with more than a dozen tabs open.

  1. I’ve noticed the same thing on my setup.
  2. Notice Kirk is using iStat Menus, a nice little utility, wraps a lot of information in a tiny interface, all under a single menu bar icon. Check it out.
