With seemingly no other recourse, I clicked Restart one last time, held down Command-Option-R to boot into macOS Recovery, and reinstalled the operating system. I looked through the log and saved a copy, but none of the errors looked all that problematic.

However, clicking the Restart button just brought up the screen and error dialog again.

Instead of booting normally, I ended up at a screen containing only an Installation Log window and an error dialog saying “The macOS installation couldn’t be completed.” That was confusing since I hadn’t asked the App Store app to install macOS 10.13.4. Restarting my AirPort Extreme Base Station didn’t seem to help, so I restarted the Mac.

A few days ago, I got up early to get some writing done, but my 27-inch iMac’s Internet connection was being horribly slow, and the entire machine was struggling. It’s unusual that I see something entirely new on my Mac.

And if you run Linux (and a lot of Mac guys also use Linux), the impact of patches is quite significant, according to numerous reports. Most of us 'typical' desktop users, won't see much effect from either Spectre or Meltdown patches, but Sys Admins and IT guys running servers definitely have been impacted. The impact of Spectre patches seems to be more significant than Meltdown, particularly for I/O intensive situations. And surprise, how AMD Zen architecture is less impacted than Intel (by happenstance, not because of brilliant forward thinking on AMD's part).Īlso, significant difference in discussion of Meltdown vs Spectre patches. The article goes a little more in depth on how impact can be different depending not only OS, but generation of CPU (older CPUs are impacted more than newer -lake processors. I'm posting this comment because recent updates for macOS include (so it is said) patches for Meltdown and Spectre.
