Leaving htop running (best in background in a screen session on some server) is such a waste of CPU resources. I've already seen that multiple times and always wondered if the people don't recognize by looking at htop's output how much CPU resources it wastes.

I hit a breaking point with the Apple laptops a couple of years ago. It was actually iTunes that drove me off. iTunes Match somehow corrupted and lost a bunch of my music. Forever gone and I didn't have backups. After working with Support for a while, I finally gave up and bought a new ThinkPad T470s and put Arch Linux on it and never looked back. Things work really well and predictably. I have it dialed in just how…

That's like asking someone with Dropbox storage to make sure they have a secondary backup on an external HDD somewhere. It's not that it wouldn't be a good practice, it's that Dropbox should be the one making the backups of their backups.
Re: Leaving htop running freezes macOS High Sierra
#143Reading the bug report:
1. Increasing htop's refresh rate (-d 0.1), and having a tight loop that spawns processes quickly, tends to reproduce fairly reliably. 2. Running htop as root seems to work around the problem.
I was able to reproduce the crash with (1), and not able to with (2) after running htop for several minutes. My first thought was that it didn't have to with running htop as root, but rather running htop as a different user as the one spawning processes. So I repeated (1) except that I ran htop as myself, but the spawning loop as nobody, and the crash went away.
I wonder if the bug's in the resource limit checks (RLIMIT_NOFILE, RLIMIT_NPROC), and if increasing the limits would delay / mitigate the crash. But I don't feel like crashing my machine anymore tonight to find out...

This is why we can’t have nice things--random reports of things not working are pretty meaningless without context. 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…
> This is why we can’t have nice things--random reports of things not working are pretty meaningless without context No they are not. A lot of the same reports with same combination of htop + iTerm should prompt the company to investigate. At least when they are selling $2k "premium" machines. > I’ve installed htop many dozens of times using Homebrew on a variety of Mac hardware Neither did I except since I upgraded…
> doesn't run with admin privileges
To run correctly on macOS and display all processes htop needs to be root via sudo/setuid.

I came for the filesystem bugs, I stayed for the absurd root exploit, but its the little crashes, rendering glitches, and feeling of general instability that made me fall in love with High Sierra...
APFS has been nothing but pain for me. File system changes show up in Finder minutes later! I should have stayed in Sierra.
And to think that ZFS for FreeBSD had already been up and running for years...

Store the screen layout using serials from the EDIDs. Why it doesn’t do this and “tries” to guess their position somehow is beyond me. I use the OWC TB3 dock with dual Asus PA328qs with the latest firmware. Because of apparently some lame design decisions, in order to run dual external monitors over a single TB3 port, you need the dock, which has one DisplayPort output, then a TB3-> DisplayPort (via USB-C alt mode II…

Someone did go through the trouble of reverse-engineering the fingerprint sensor. The code works on my thinkpad.

Only thing left is someone willing to clean up the code and upstream it.

#147High Sierra seems like a great OS if you want an unstable workstation that doesn't work with tools you've used everyday for well over a decade.

Rendering glitches when in Chrome are awful indeed and happen way too often
Re: Leaving htop running freezes macOS High Sierra
#148People are missing the point-- it's not an htop problem since a simple console app running as a user should not be able to do this at all. This gives me the willies. Methinks another OSX security bug is incoming.
Yea, if I had a Mac box, I'd be looking at that call stack the author posted and fuzzing the hell out of those functions. There's a DoS bug bounty in there somewhere.
Only if Apple invited you to that competition (https://www.macworld.com/article/3104671/security/apple-anno...). Others only get credits.

I'm not a developer, but I knew developers were previously content with Macbooks usually running OSX or linux. Given so much unhappiness with OSX, and the inability to run linux on the USB-C macbook pros, what are developers generally doing? The Apple hardware is nice, but it generally means you have to use OSX. Windows WSL is pretty convenient, but then you have to use Windows. Linux is, of course, great, but what h…
> Linux is, of course, great, but what hardware? We are in 2018, not in 1995. You can easily find good desktop and laptop that run fine under pretty much all major distros. Especially if you compare to MBP & the like, meaning you have no budget issues...
Apart from high DPI displays which is not great at the moment.

Even if htop doesn't work correctly, and is complete garbage it doesn't install kernel extension and doesn't run with admin privileges so it shouldn't freeze the machine or render it unusable which is seems to do. Turns out it doesn’t, but it’s not unusual for people to make these types of unsubstantiated claims; turns out it’s a build issue that conflicts with High Sierra. The Homebrew team updated the formula so it…
> Turns out it doesn’t, but it’s not unusual for people to make these types of unsubstantiated claims What are the unsubstantiated claims? That these people including me are lying and have made this crash up? Do you really believe that? > turns out it’s a build issue that conflicts with High Sierra. Thanks for checking, but what is the build issue is exactly? The original point was that unless htop installs kernel ex…
Whatever the system issue was is fixed for some and certainly for me on 10.13.2 or newer when running htop.
