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…

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…

Hey I’m not the only one to have Match corrupt my library on apples servers and lose music?!

Lucky for me I have a copy of all of it on my 2011 iMac hiding in my closet.

I’ve been finding the root cause of this a month ago, but don’t know where to look due to lacking of experience in kernel debugging. If anyone here could lend me a hand, please send me an email at (es at evsfy dot com)

why keeping the root cause for yourself? Try to mention it at least here or write on the htop bug list page what you know. It would help us all I guess.

I recently bought a ThinkPad X1 Carbon. I'm pretty happy with it.

A useful filter when buying laptops is "does this laptop have the service manual accessible to mortals?" Handily filters down to 2 companies: Dell and Lenovo. I am unsure about Librem and PogoLinux.

HP has service manuals available too, including their consumer models.

Oddly they come with the disclaimer "IMPORTANT! This document is intended for HP authorized service providers only." which makes you wonder why it's available to download from the support website.

High 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.

As a sysadmin at my company, I have regular questions from my users (C++ developers) about upgrading from Sierra to High Sierra due to Apple's invasive and unavoidable notifications. After the root-exploit balls-up, I forced the two people who'd upgraded back onto plain Sierra. But I know at some point it'll stop giving us the option to ignore.

I am beyond flabbergasted at how much these idiots have managed to break between Sierra and HS. They must literally be high when they say 'this is good, let's ship it'. The OS is abysmally unfinished, and with each of these stupid failures we're going past Vista levels of unfinished. These are tools I use in my daily workflow (thankfully I use Linux instead), and other developers in my company use these tools. At this point, upgrading to HS would be a massive step backwards for us.

I literally cannot believe how sh*t MacOS has become. It's a cesspit of broken Unix with a shiny iOS layer covering it. I absolutely loved Snow Leopard and cannot believe it has evolved (or mutated) into this. I'm beyond pleading and into exasperation.

APPLE, WILL YOU MAKE AN OS WE CAN ACTUALLY USE?!

APFS has been nothing but pain for me. File system changes show up in Finder minutes later! I should have stayed in Sierra.

My MacMini6,2 (2012 Server) has two SSDs RAIDed together. High Sierra beta worked fine and upgraded fine to golden master and subsequent. When I decided to reinstall my OS from scratch and reload from backups I discovered to my horror that mine was not a supported configuration and there was no way in hell I would be getting back to where I started from. This happened on the 20th November. I finally managed to boot m…

I've felt for a long time that Apple have lost interest in their end-user computers. MacOS Server has long seemed like 'if you REALLY want it, here, have fun'. But the tools tended to work. SoftRAID somehow works fine on Windows, why not on Mac.

Can't imagine how much pain you've been through with this. Got enough backups to revert back to Sierra?

Reading 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…

Some nice digging there, thanks for the info!

People 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.

This is exactly why I cringe at these seemingly minor issues - sure htop breaks, it can be worked around, but the root cause is more fundamental; an unprivileged user should not be able to crash the whole OS just by reading the process table, no matter how invasive.

It makes me think what they have decided to change between Sierra and HS to cause this sort of failure. This is pretty fundamental and implies some tinkering deep in the kernel, potentially without fully understanding the repercussions. With the number of security holes that can be easily opened by naive tweaks to low-level code, I think we're right to be nervous about what they've done to cause this.

I did post my findings on the GitHub issue :-)

I stuck with the hardware (albeit quite old) and went linux for similar reasons. The older hardware can be quite nice with linux, but my next notebook wont be a mac, not due to value for money (spec and built quality balance is actually quite good for price these days), but because all attempts to run linux or any OSS on the more recent models are a disaster.

Try a modern ThinkPad with Intel graphics. I promise, it will work great.

I know it's a traditionally good brand for compatibility, but for me they sort of dropped quite far from the top of the list since becoming a chinese owned company and for superfish etc. (To clarify my problem with it being chinese is the prevalence of injecting backdoors into absolutely everything from state or otherwise, and these days we have to worry about hardware too)

If I was to buy right now my list is roughly in the order of:

    - Dell XPS 13/15
    - Razor Blade (It's getting official linux support soon)
    - Librem 13/15
    - One of the million and one thinkpad models although I have no idea which
I'm most likely to just wait longer though :P the only thing to die on this old thing so far is the keyboard springs out of sheer wear and the battery. I'm gona replace the keyboard soon myself.

My 2015 13 inch MBP is still on Sierra. Should I indefinitely hold off upgrading to High Sierra?

Yes. Stay away. I downgraded my mac back to Sierra from High Sierra and don't regret it at all.

+1. I used to upgrade to each new release of Mac OS X in the first few days. That policy worked for many years, but my experience with High Sierra was so bad that I downgraded and never looked back.
