If you're on a Mac, you can find the exact processor model number by opening Terminal.app and entering

  sysctl -n machdep.cpu.brand_string

this will return something like

  Intel(R) Core(TM) i7-4650U CPU @ 1.70GHz

(Found on http://osxdaily.com/2011/07/15/get-cpu-info-via-command-line... )

This is kind of like cutting off your leg because of a hangnail. I've been running a Skylake MBP for more than 6 months for compilation workloads and haven't seen a single processor hang.

I'm much more annoyed by the completely unpredictable desktop assignment on monitors when hotplugging DisplayPort connections on multiple displays. This one bothers me every day.

> haven't seen a single processor hang

If there was data corruption you might not notice.

That's weird re monitor issues. I've been impressed with how consistent mine are.

What I see:

Same monitor/monitors plugged into same ports produce consistent configs.

I get a unique config per monitor/port.

I agree. I've been fine myself. But if people feel the need to turn it off. ;)

No. Even though Skylake came out in 2015, Apple used an older CPU (Haswell) until the October 2016 MacBook Pros.

They used Skylake in late 2016 MBPs and Kaby in the 2017 models.

I'm on a Kaby

    Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz

I haven't seen any erratic crashes yet on code compiled by LLVM 8.1.0 on multiple projects (ROS, Qt5). I hope a microcode fix is pushed by Apple on behalf of Intel soon.

Are you from the future? Isn't LLVM currently at 4.0 and going for 5.0 soon?

macOS comes with Apple's build of Clang, which has different versioning from "proper" Clang.

That's going to be mess when LLVM proper catches up to those version numbers...

It prefixes the version with Apple LLVM so I assume it is versioned differently.

From one of the 2016 MacBook Pros:

> machdep.cpu.model: 78 > ... > machdep.cpu.stepping: 3 > ... > machdep.cpu.microcode_version: 174

Can't find if 174 is the fixed version or not.

So this is one of the models for which there exists a fix, as per the email.

I'd also like to know if 78 is the fixed version.
