Yes, it’s fodder to continue to dump on Apple—I get that. But it certainly doesn’t help solve the issue, assuming there’s really an issue in the first place.
For the record, I’ve installed htop many dozens of times using Homebrew on a variety of Mac hardware and operating systems over the years and have never experienced an issues.
After many years of Mac IT tech support, I can tell you: it’s usually what’s not being reported that's the problem.
Was this a clean install or was it upgraded from a previous version of macOS?
Are there 3rd-party kernel extensions installed? Pretty common with antivirus software and hardware drivers.
When’s the last time Disk Repair was run? I’ve seen corrupted/damaged hard drives cause machines to kernel panic or hang.
Did htop ever work correctly? If so, when did that change?
I’d be pretty surprised to hear a new iMac that was unboxed and had Homebrew and htop installed would crash. Actually, if that were the case, they could boot into the recovery partition, format and reinstall.
I clean-installed macOS High Sierra 10.13 the day it was released on a 2009 iMac and have been running the public betas and haven’t had any issues since.
I’m running macOS High Sierra 10.13.3, build 17D29a. I’ve installed 157 command line and 71 GUI applications using Homebrew…
As someone mentioned, it’s only the problems that are part of some narrative that make news; people like me don’t post “Hey—I’m a web developer and I’ve been using High Sierra on a nearly 10 year-old iMac with zero issues, even when running beta versions”.
This doesn’t excuse Apple at all for the bugs and vulnerabilities that have been well-publicized; but lets not make it seem worse than it actually is.
Apple has already starting releasing mitigations for Meltdown and Spectre, like many OS vendors are doing.
I run a FreeBSD server on Digital Ocean; here’s their statement:
FreeBSD was made aware of the problems in late December 2017. We're working with CPU vendors and the published papers on these attacks to mitigate them on FreeBSD. Due to the fundamental nature of the attacks, no estimate is yet available for the publication date of patches.
This is pretty underwhelming, especially given the severity of these vulnerabilities.
