The links found via [Wayback/Archive] macos kernel_task high cpu dual screen – Google Search were daunting.
In the end, the issue ways way easier to fix than I thought: open up your Intel MacBook (you need pentalobe screwdrivers for that), then with some compressed air, clean the dust (especially from the fans).
This post saved my day [Wayback/Archive] kernel_task takes up 500% of my CPU when plugging in external monitor – MacBook Pro 15″ Retina Display Mid 2015 – iFixit
Things I haven’t tried yet:
- Cleaning out more free space from HDD
- Using plain HDMI cable into the HDMI cable port
- Taking MBP apart and cleaning any potential dust
…
I faced the very same issue that you guys are facing and based on input from another forum decided to get my 2016 MPB fans cleaned out.
This made an immediate impact where when I connected my external display to the MBP.pre-cleaning, it would overheat causing the fans to spin at 6000 rpm or thereabout and the kernel_task would eat up 500%-900% of the CPU rending the system unusable.
This simple cleanup of the fans has allowed me to connect the monitor with no kernel panic anymore and even though the fans run around 5000 rpm now the CPU and GPU are running around 10 degrees cooler now.
The same picture is in [Wayback/Archive] macos – MacBook Pro high CPU with external monitors – Ask Different.
An even dirtier MacBook was at [Wayback/Archive] External Display – High CPU Usage – MacBo… – Apple Community.
Links that were interesting but unhelpful:

From an interesting thread where Iris Classon had laptop overheating problems (just like I had with a 2015 Retin MacBook Pro in Cleaning the cooling fans of a 15-inch Retina MacBook Pro 2015 model):
My tray is from the lid of a broken container.
I love repurposing the remains of old household items..
The actual problem: dust, just like my MacBook had.

This revealed so much pain: [Wayback] gist include image in markdown in current directory – Google Search
I wished that – like in the past – it would work just like in a normal github hosted git repository: [Wayback/Archive] How do I display local image in markdown? – Stack Overflow.
The core problem is that though a gist underneath is a git repository, it is rendered in a way that is different than a github repository is rendered, and that way of rendering has changed over the years effectively making it difficult to embed a picture. When you do embed an image requires the uuid/guid of the raw image URL to be included in the markdown, unlike with a regular repository hosted on github.
That is so much pain that I decided to not host documentation in gists any more.
A bit of the pain:
This is an example gist where I tried to host an image: [Wayback/Archive] Windows 7 with PowerShell v2 fails to upgrade to PowerShell v3 through chocolatey: You must provide a value expression on the right-hand side of the '-' operator.
That gist was prelude to my post Chocolatey on Windows 7: “You must provide a value expression on the right-hand side of the ‘-‘ operator.”.

A long time ago, on just one system, I forgot which one, I needed explicit [Wayback/Archive] linux – Newline-separated xargs – Server Fault.
The simple solution was to replace the newline with null before running xargs:
tr '\n' '\0'
The clean solution was to install [Wayback/Archive] gnu xargs:
GNU xargs (default on Linux; install findutils from MacPorts on OS X to get it) supports [Wayback/Archive] -d which lets you specify a custom delimiter for input, so you can do
ls *foo | xargs -d '\n' -P4 foo

I was not aware you could this: [WayBack] UniFi – Install a UniFi Cloud Controller on Amazon Web Services – Ubiquiti Networks Support and Help Center
Giving it a bit more thought, I’m not sure I would want this, as it would presume you have an internet connection that is up on the WAN side.
You’d need this before installing any of your Unify equiment, even when installing your first Unify router, which would mean a chicken and egg problem.
Also it would mean you can only use the cloud key when the WAN is down, you cannot use the cloud-key, not even locally.

Be weird, be happy, be proud!
Today is already the 3rd edition of what in 2021 was announced as [Wayback/Archive] Weird Pride Day. The first ever Weird Pride Day is this… | by Oolong | Medium
The first ever Weird Pride Day was on the 4th of March, 2021, and the second is on the 4th of March, 2022.
This is a day for people to embrace their weirdness, and reject the stigma associated being weird. To publicly express pride in the things that make us weird, and to celebrate the diversity of humankind.
Many people need desperately to receive this message: ‘I feel and think much as you do, care about many of the things you care about, although most people do not care about them. You are not alone.’
– Kurt Vonnegut, Timequake
…
Be safe, be kind, be weird.
Share your Weird Pride Day posts with the hashtag #WeirdPride and/or #WeirdPrideDay, and on the Facebook event….

Cool: [Wayback/Archive] Canarytokens
Canary tokens are a free, quick, painless way to help defenders discover they’ve been breached (by having attackers announce themselves.)
How tokens works (in 3 short steps):
- Visit the site and get a free token (which could look like an URL or a hostname, depending on your selection.)
- If an attacker ever uses the token somehow, we will give you an out of band (email or sms) notification that it’s been visited.
- As an added bonus, we give you a bunch of hints and tools that increase the likelihood of an attacker tripping on a canary token.
The above documentation is just a small portion of what is at [Wayback/Archive] Canarytokens.org – Quick, Free, Detection for the Masses with even more documentation starting at [Wayback/Archive] Introduction | Canarytokens.
Source code (either the site or a docker image):
It is provided by [Wayback/Archive] Thinkst Canary.
I learned it at the height of the Log4Shell mitigation stress. Some related posts from that period:
