sudo kill -HUP $(pgrep powerd) (I don't have an answer for 'why')

I had the same trouble, and to a headless Mini also. This is what I found that worked… sudo launchctl unload /System/Library/LaunchDaemons/com.apple.screensharing.plist sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.screensharing.plist I had the opportunity to install an SSD in my Mini, and did a clean install of Lion at that time, and ...

I'd like to offer an improved answer, that the author may consider for the question. The previous answer's AirDisplay drivers actually messed up my remote client, and left me with 16 virtual displays, all with the same information, where I couldn't click anything. Luckily I know how to navigate Activity Monitor with the Keyboard :-) . I found the following ...

My issue was that my Magic Mouse was discoverable through the Bluetooth Preferences pane, but when I clicked 'Pair', it couldn't connect. After an hour, I found a solution that worked: Turn off the Magic Mouse Open the Bluetooth Preferences Delete your mouse's profile Be sure the Bluetooth Prefs pane is searching (indicated by the spinner) Hold the mouse ...

Just downloading Display menu from App Store (free) and choosing highest resolution worked for me on Yosemite. Now running headless with great remote screen resolution. No other actions required.

Have you tried to stop powerd by Activity Monitor? This solved the CPU consumption for me. But after stopping powerd I got strange effect in Activity Monitor - it was like Update Frequency was changed from Often (2 sec) to Nonstop (0 sec), i.e. continuous without any delay. So I had to quit Activity Monitor too. After these operations and restart of ...

Same error happened to me when I received an update from 10.13.1 to 10.13.2. If you boot with shift button pressed, you will be able to enter safe mode and try to download and reinstall an update. It did not help to me so I booted holding Option key and chosen regular Mac HD (not an update volume). Booted to my Mac without safe mode and tried to reinstall ...

Shutdown vs. Sleep is a constant question. It used to be that shutting down the early OS X machines caused issues with timed log cleanup routines. That's pretty much a non-issue these days as the OS recognizes when the routines haven't run and will reschedule them. Another concern has been restarting to free up memory or just make the machine more stable. ...

On my computer, it was Activity Monitor which caused the powerd process to use a lot of cpu (20-30%, sometimes 50%, resetting the SMC didn't help). Quitting Activity Monitor "solved" the problem. Checked in the Terminal by running top.

The easiest solution is the one by commenter Michael Buen. It has worked on 20 Macs I've seen have this issue. Apple Menu -> Select Startup Disk -> Restart (after clicking your boot drive) resolves the issue, at least temporarily. This can be done at the error screen, by clicking on some empty space in the grey message box to get the apple menu bar to ...

You can disable the Bluetooth Setup Wizard by: Go to System Preferences Click Bluetooth Click Advanced Un-check 'Open Bluetooth Setup Assistant at start up when no input device is present'. The screen should look like this (the checkbox above the highlighted section): More information in this Apple KB - Wireless Input Devices Also, if you are not using ...

Not sure how it was 2 years ago when this question was asked but I confirmed that this work out of the box for me now. Mid 2010 Mac Mini running OS X Mavericks 10.9 Client machine tested: Windows 7 Pro using TightVNC Viewer, iPad using iTeleport. Both client devices were able to connect to Mac Mini via VNC and log in to different user accounts at the same ...

Follow these instructions: Turn off the mouse by holding down the power button until the light goes out. Turn on the mouse by pressing the power button, and keep the power button pressed until it is paired. The light on the mouse will start blinking, it will show up in Bluetooth Preferences, and you will be able to pair it almost immediately so long as you ...

As with any computer which does not have a battery you will lose everything not saved to disk if you unplug the computer from the power supply. If you use a Mini in an unstable environment, adding a UPS might reduce the risk of data loss.

There are a few built-in settings in macOS and a 3rd party app that you should be looking at: Under System Preferences → Energy Saver → Power Adapter, enable Restart after power failure. Turn on automatic login by going to System Preferences → Users & Groups → Login Options → Automatic Login and select your preferred user account. You may also wish to ...

I succeeded to update the resolution on my headless Mac Mini Server with the most simplest option: Just hold the 'Option' key while you press on 'Scaled' button in the settings. This will bring up all available resolutions and you can change to whichever you like.

This is what worked for me, based off of this post: https://medium.com/@aeronode/how-i-fixed-my-non-booting-macos-high-sierra-installation-45d238b78c3d Restart in recovery mode (Cmd-R), Utilities -> Terminal find / -name OSInstall.mpkg # Will be found somewhere in a tmp directory mkdir -p "/Volumes/Macintosh HD/System/Installation/Packages" cp "<...

I had the same error - turned out to be a disk space error. Opened up terminal from the recovery screen where it was asking me to reboot and cleared out several gigs of VMs and it worked after a reboot. I went ~15GB of free space to around 50GB, hope that helps someone else!

An old thread, but in case anyone finds this via Google, I will be a drive-by good samaritan: I'm running 4x 1920-res monitors with a 2011 mini, as the poster wishes. Number one is connected via HDMI; number two is connected via Thunderbolt. These two are fast enough for movies and 3D gaming. Number three and number four are connected with two USB adapters, ...

Stacking is not recommended. According to the Mac Mini user guide it is not recommended to place anything on a top of a Mac Mini, since its can interfere with the Mac Mini's Antennas for Wifi, Bluetooth and optical drive operation. Additionally, since that area kind of gets hot on my Mac Mini Late 2009, its probably not a good idea to cover it, since the ...

YES, it's definitely worth it. With my setup, sustained transfer speeds were roughly 75% better using SATA, vs. USB3. I tested both configurations using ZoneBench as follows: SSD: 120GB OWC Mercury Electra 6G Mac: Late 2012 Mac Mini, 2.6Ghz core i7, model ID Macmini6,2, 16GB RAM Hot-Swap unit: StarTech USB3-to-SATA dock, model SATDOCK22U3S ver2 All ...

Create a ram disk :-) From the answer to Mount a RAM disk on boot: You can create and mount a RAM disk with the following Terminal (i.e. shell) command: diskutil erasevolume HFS+ "diskName" $(hdiutil attach -nomount ram://2048) Where 2048 can be any number and represents the number of 512 byte blocks you want to allocate. So 1,000,000 will get you ...

"Invalid or missing service identifier" seems to mean that your plist file has not got or has misspelled a section like <key>Label</key> <string>com.foo.bar</string> Note "Label" must start with upper case L.

The easiest way to tackle this is to treat the Mac mini as if it had a blank drive and you needed to (re)install macOS from Internet Recovery. Install OS on iMac with blank hard drive is a post that has all of the steps involved in getting a "factory fresh" install of macOS on your machine Your late 2012 mini already supports Internet Recovery If all else ...

Thunderbolt contains a DisplayPort channel. You can get a Thunderbolt/Mini DisplayPort to DisplayPort cable. I found a cheap one on Monoprice a while back. Here is a 6 footer.

It depends on which version of the Mac Mini you have. According to this Apple Support KB article, older Mac Minis can connect with a normal DVI port, which you can buy a DVI-VGA adapter for. While the generation after that offered Mini DVI and Mini DisplayPort outputs, both of which can be adapted to VGA output. Then immediatly after that there was a ...

The culprit was indeed systemstatsd. The way I understand it, that process both produces a number of system stats, dumps them into a file which it later analyzes. For some reason, that file never got reset, resulting in a giant stats file that took serious resources to analyze. What I did was stop the analysis daemons, sudo launchctl stop com.apple....

Alright, I see you've added some requisites to your answer. Here goes. Part 1: Install Ubuntu 16.04 Server. Download this. (Ubuntu Server 16.04 32-bit) This is done the same way any other Linux install is done. You will insert the CD/DVD, run through the setup to take the entire partition of the Mac Mini, and once you reach a desktop, you're ready for ...
