WOL with an iMac (10.13.6)

I didn’t manage to setup WOL (Wake on Lane) from my iMac run-on 10.16.6.

  1. I do have Wake for network access enabled from system preference / Energy Saver

  2. I did enter the ethernet MAC (and not the airport one)

I have this setup on my router (Synology RT1900AC), when I manually turn on my iMac, the router detect and there is a lightning cable next to the MAC address (but I guess that maybe just because the network detect some packet from this MAC …)

Is there something else I’m suppose to do in order to have WOL working?

Shut down dialog in wrong Language – MBP High Sierra 10.13.6

My Preferred & Primary language is set to english (The region is however set to Germany) as shown in the image below.

When I try to shut down or restart, I am presented a dialog in German language.

I have tried to solve this by running sudo languagesetup in the terminal to set the lang by selecting Use English for the main language then restarting. This had no effect.

Running defaults read NSGlobalDomain AppleLocale in the terminal outputs en_DE

Mac OS (High Sierra 10.13.6) volume control spontaneously runs; can I disable it?

I have a pretty old MacBook Air (bought it in 2011), so I’m thinking it’s probably to do with the keyboard wearing out. But I’ll be watching a video or something and the volume control will run up to the max, as if holding down F11, or run all the way down as if holding down F10. (Since I installed High Sierra, these keys have shifted one over to the right, so F12 and F11 really.)

I’ve tried several things: restarting system, cleaning keyboard, etc., setting it up to hold down the Fn key as well as the function key (doesn’t change anything), installing updates. Nothing seems to help.

So, unless anyone has any other ideas, I’m presuming that the problem is hardware-related. I don’t really use the system volume control anyway; prefer to control it from within the video itself. Is there a way to disable it, without disabling the ability to control it from within, say, youtube videos?

(Edit: I tried resetting the PRAM by holding Option-Command-P-R on reboot after a complete shutdown. The problems haven’t reoccurred after some hours of use. I’ll post it as an answer if the problem doesn’t resurface after I give it a few days.)

macOS High Sierra (10.13.6) Cannot Install Updates

I’m having difficulty installing the latest update on my Mac Mini from 2001 (macmini5,3).

The current pending update is “Security Update 2019-003-10.13.6.” When I attempt to install the update:

  • It downloads the update.
  • It asks to reboot.
  • It gets ~5% through a progress bar then pops up an error message: The update was not installed successfully. You can try updating again in the App Store after restarting.

I have attempted in order:

  • Manual download and install of the update.
  • Fixing disk issues in repair mode (none were found).
  • Installing the update in Safe Mode.
  • Installing the update in Repair Mode.
  • Reinstalling macOS.
  • All of the above again, with a support tech in chat. After which he stated he couldn’t help me and I should go to an Apple Store for support.

The issue that triggered the wave of triage, is that Dropbox needs to be manually upgraded by downloading a new version. The download is delivered as a .dmg. It turns out that in this state, the os is unable to open a .dmg and fails with “detaching because no mountable filesystems.” This same message is displayed for both the dropbox updates as well as the apple system update (SecUpd2019-003HighSierra.dmg).

I “feel” (hahaha, no data to support this) like the format for .dmg file has changed. And apple failed to release an update to this version of macos such that the format is no longer readable.

macos installation couldnt be completed from 10.13.6

My macbookpro is a year old, and has never had a problem till now. Just tried to update it, but it wont bootup after. I tried booting in safe mode, but this didnt help. I was able to boot of the main “drive”,

The log files have lines like this:

- Failed to open file <private> [2: No such file or directory] - The main OS Installer distribution (/Volumes/Macintosh HD/Library/Updates/AtomicUpdates/041-53308/041-53308.English.dist) did not load with error: The file doesn’t exist. - Folder Manager is being asked to create a folder (down) while running as uid 0 

I have read there are a few options:

  1. reinstall OSX. This sounds too drastic.
  2. try doing the update again?


iMac macOS High Sierra 10.13.6 white/grey screen and progress bar

I no longer have access to my iMac since 2019-03-26, the last date that it worked normally.

I restarted my iMac on 2019-03-26 and since then it does not want to display the desktop anymore.

It shows me Apple logo and the progress bar then it stops there.

I have tried everything (every started mode) including safe mode that does not work at all. I tried to Reinstall with internet, the installation finished and when restarting no change, still have Apple logo and progress bar then blocked.

The verbose mode (CMD + V) loop this message : IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

Can someone help me please I’m new to the Mac environment and in our city there is no Mac Support because this one I bought online.

Thanks for your help.

Here is the blocked screen:

macOS High Sierra 10.13.6 empty trash sound playing repeatedly

I am trying to figure out how to convert a piece of sheet music to XML file for a student. I heard about Pizzicato app for macOS. I downloaded it, and then attempted to use it (couldn’t figure it out). When I closed Pizzicato app, (it was using Terminal.app) and then deleted it, it kept making the trash can sound over and over again.

Did I mess something up by not following a procedure correctly? I don’t know anything about Unix/macOS, other than it’s reference in Jurassic Park 😉 This is a brand new MacBook and I’m nervous something’s awry. I restarted it right after it started making the sound and it did it well, and it feels like all the programs are running OK.

Should I take it in to have someone look at it?

Cannot seem to install VMware vCSA 6.7 cert on macOS 10.13.6 High Sierra

Trying to install the web certificate for my vCenter Server Appliance (vCSA 6.7) on my Mac Mini (running macOS High Sierra 10.13.6). I download the cert.0 file, change the extension to .crt and double-click the file, Keychain Access opens…but then nothing. The cert does not get installed. This is exactly how I’ve always installed the cert on machines before. Where could be going wrong here?
