Today I got an email from the developer Niels Mouthaan, who gave me his app Ejectify has presented. The function of the app is quickly explained:
Ejectify automatically unmounts external hard drives when your Mac hibernates and mounts them again when you wake up.
So far so good. Unfortunately, I had no idea what this would be helpful for, because the hard drives usually just stay mounted when the Mac goes to sleep and are still there when I wake up. So why the circumstance with this app?
Chapter in this post:
Use case: monitors with built-in Thunderbolt hub
After I wrote to Niels that I would like to introduce his app, but I just couldn't think of a scenario where this software would be of practical use, I promptly got his answer:
In most cases it indeed doesn't matter. The scenario that bothered me causing me to develop Ejectify is this: my Time Machine is connected via a USB hub that's embedded in my external screen. When my Mac instructs its screens to start sleeping the hub is getting powered off and the disk is getting ejected forcefully. When my Mac wakes up, I get this annoying "Disk not ejected properly" notification and I have to unplug my external screen and plug it in again to make the disk appear.
Users are also using it to safely disconnect their external drive when their Mac is sleeping without opening it first to eject it properly. This is the most common scenario.
Translation from my buddy DeepL:

Monitor manufacturers accept the destruction of data
And I have to say: I had exactly this problem with my LG monitor, which has a built-in hub. Immediately after setting it up, I hung my external hard drives on the monitor in order to have as few cables as possible on my MacBook Pro.
Unfortunately, the hard drives just turned off when the Mac went to sleep. It was completely incomprehensible to me why the monitor manufacturer had built in such an automatic power-saving system, since it can turn a hard drive into a mess of data if you cut off the power in the middle of writing.
My conclusion about the built-in Thunderbolt hub in the monitor was that I just stopped using it. Every time I found these messages just too annoying. And somehow the risk was too great for me that at some point a hard drive or at least the data on it would bless the time.

My conclusion on Ejectify
If you want to use a monitor with a built-in Thunderbolt Hub on your Mac, you should buy the 3 Euro app. It makes the operation of external data carriers on the monitor hub safer and also saves your nerves because it prevents many warning messages.
Ejectify: Mandatory App For Owners of Thunderbolt Monitors
For me, Ejectify makes the hub function in my LG monitor a useful thing again - although I have not used it for years in order to protect my data on the hard drives.
If you're interested in Ejectify, you'll find the software here on the app's own website.
Mountain.App - same function, unfortunately neglected
Surely there are people who say “Yes, that already exists. The app is called Mountain! ”… That's true, because Mountain from the appgineers fulfills almost the same functionality, but on the one hand the developers want 5,99 euros for it and on the other hand the last revision of the app is from 2012. I'm not sure whether the software still runs on macOS Big Sur at all.
So my tip: Take the solution from Niels, because it is very fresh and the developer takes care of the tool. The source code is even on Guthub available.
