The umbrelOS is a server OS for everybody. People who aren’t familiar with the command-line interface can just start their homelab using umbrelOS without any technical knowledge. And for people who already have one, umbrelOS can make an excellent addition to an existing setup. It feels polished and everything just makes sense. The labels on the buttons are easy to understand.

On the dashboard, you have a desktop-like home. Front and center we have the live resource usage stats. Below it, there is a dock.

Upload or browse your files

This file manager looks and feels a lot like the Finder on macOS with tabs for applications, documents, downloads, recents, photos, and videos. Here you can browse files that you’ve already uploaded to umbrelOS.

Copying, pasting, creating new files or folders, compress/uncompress work just like on desktop file managers.

Install self-hostable apps with one click

To download and run apps on your home server operating system, you typically use command-line package managers or Docker commands to host them as services on your phone.

The umbrelOS takes away all that complexity and gives you a simple app store where you can install any of the hundreds of self-hostable apps with a single click. Most apps that most people need are already here, so this store should suffice for most people.

Docker is what makes umbrelOS, and other graphical server operating systems like it possible. Under the hood, the “apps” are just Docker containers.

Quick app launcher

The shortcuts to your installed apps are also on the main dashboard. You can click these shortcuts to open the apps in a new tab. Swipe left if you don’t see them. These shortcuts save you the trouble of having to find and memorize the port numbers or IP addresses of your apps. On umbrelOS, just click the app icon, and it will open in a new tab.

Spotlight-style search

Access settings, files, apps, and more in one place You can press the shortcut Command+K or Ctrl+K to open a search bar. This works like Spotlight search on macOS or the command palette on Windows.

You can use it to launch installed apps or search for apps to install on the app store. It can look up files for you. It can do actions like rebooting the server or creating backups. And, of course, you can search through the files you have on this umbrelOS machine in that search bar.

Easily share files with other devices

You can go through umbrelOS settings to set up file and folder sharing.

Select which folders you want to share, and then connect using the instructions, alongside the username and password it generates. Then, on the other device where you want to access the shared folders, enter the umbrelOS smb link. Your username and the password as shown in the settings app.

smb://umbrel.local/

Just like that, it’s now showing up as a network drive on my Finder.

Back up your entire server

When you’re trying to host things on your local network, some things are bound to break or fail randomly at some point. When that happens, it’s a good idea to have the right backup system in place. This is another part of the job this OS excels at wonderfully. On the settings menu, there is a backup menu with two buttons.

• Set up > Another Umbrel or NAS > External Drive
• Restore > Full Restore > Rewind

This will back up your umbrelOS machine to another umbrelOS machine on your network, network-attached-storage or (NAS), or a physical USB drive plugged directly into the umbrelOS machine.

You can restore those automatic backups in two ways.

• Full Restore rebuilds your entire umbrelOS on a new machine.
• Rewind is a “time machine” that restores umbrelOS to a specific save point.

A polished point-and-click user interface for a home server operating system

The umbrelOS is completely free and it’s open-source. It has everything you could need to get a homelab started and make (there are some exceptions like running services which require HTTPS).

You are trying to visit a specific website on your Mac, but you encounter connection errors like “Server Not Found” or “404 Not Found”, even though the site works fine on other devices in the same network. This usually happens when your Mac saves an outdated or corrupted Domain Name System (DNS) record in its local cache after a domain migration or network configuration change.

As a beginner, I used to feel like I was fighting with the command-line interface. It did eventually click for me, but I wish it happened sooner. This is a list of command-line actions and commands that I wish I had learned on day one.

There was a time when you could get by with a few minor tweaks to the default settings, or even some lightweight de-bloating script when setting up a fresh Windows system. That time was before Windows 11. The vanilla version of Windows 11 is practically unusable for me, and it takes a whole rigmarole to make it usable.

If your default browser homepage and search engine keep mysteriously changing to Yahoo!, your computer is probably infected with a browser hijacker. While resetting the browser might seem to fix the problem, here’s how to do the job properly.

A browser hijacker is probably one of the least aggressive and destructive types of malware, but that doesn’t mean you should allow it to exist on your computer. These things make unauthorized changes to your browser settings so that advertising or a similar page that’s beneficial to the malware distributor is shown instead of the one you chose.

Because the people who spread this type of virus are somehow benefiting from the change of your search engine or homepage, it’s unlikely that a hijacker will cause your computer to crash or become inoperable. It can, however, cause performance problems, and can also be a sign that your computer is infected with other malware.

In this case, the virus is probably the “search.yahoo.com redirect” virus. It will redirect you to the Yahoo homepage via an intermediate website as soon as you launch your browser. And if you click on any of the links on the Yahoo homepage, any revenue from those clicks will be paid to the intermediary website owner.

We’ve all been there. Your PC starts to feel sluggish, or you’re staring at a “low storage” warning, and the first instinct is to reach for a third-party cleanup tool. I’ve done it more times than I’d like to admit. Install it, run a scan, watch a bunch of “issues” pop up, and hope it magically fixes everything. But here’s the thing. Windows has gotten a lot better at handling this stuff on its own.

The tools built into the OS today already cover the things most cleanup apps claim to fix, like clearing storage, managing startup apps, and keeping your system running smoothly. In a lot of cases, those third-party tools aren’t just unnecessary, they can add bloat, push ads, or make changes you don’t actually need. At this point, using them is a risk you can skip entirely.

In 2026, almost every PC is running a solid-state drive (SSD) of some kind. With an SSD, cold boot times are already extremely short. My PC boots in less than 20 seconds, and even an older SATA SSD will easily get you to the desktop in less than 45 seconds. The amount of time you actually save by using Fast Start-up on modern hardware is barely noticeable.

Fast Start-up can cause extra problems no one wants.

Shutting down is sometimes necessar.

The real issue comes from the fact that Fast Start-up isn’t a true shutdown. When you click Shut Down with Fast Start-up enabled, the Windows kernel stays partially loaded and drivers are kept in their current state. Despite the speed gains, that sometimes introduces problems. I’ve run into more situations than I can count where a true restart is the easiest way to fix things. Whether you’re installing new drivers, applying system updates, or trying to clear out a bugged driver state, you need a “clean slate”.

Fast Start-up gets in the way of all of that. You might notice that some updates don’t seem to stick until you do a full restart, or that bugs you’d expect to resolve after shutting down your PC and turning it back on stick around. The classic advice to “turn it off and on again” is great, but if you have Fast Start-up enabled, shutting down and powering back on doesn’t actually reboot the system—it just resumes with all the bugs in place.

Getting to the BIOS is more complicated than it should be

Fast Start-up also makes getting into your BIOS a bit more difficult. Normally, you just power on the PC and rapidly tap F2 or Delete to enter the BIOS. When Fast Start-up is active, the system skips parts of the initialization process so quickly that the window to press those keys often disappears entirely.

However you use Linux, whatever your situation, there’s a simple way to create a new directory. The terminal mkdir command is probably the one you use the most, but there’s a lot to learn about it, and you may find a GUI app easier.

If your Linux system crashes and locks you out, you risk losing everything—files, data, time. If you have a bootable Linux USB recovery disk, tough, you’ll be ready to restore, repair, and rescue your system before it’s too late.

Why is it important to have a spare Linux USB disk?

It can happen to the most seasoned Linux users: a corrupted update operation that hoses your system, and you know how frustrating and annoying it can be to get it back up and running. While the temptation may be to start all over again, a recovery drive can save the day. A bootable Linux USB recovery disk is a fully functional Linux distribution that you can run directly on your computer without installing it on its hard drive. There are many important reasons to have a Linux USB recovery disk handy. With it, you can perform essential operations, troubleshoot issues, and access important files without booting the installed operating system.

System Recovery

Chief among the reasons for having a bootable USB disk handy is for system recovery. Linux installations are usually very stable and less prone to failure than other mainstream operating systems. However, bad things can happen, and a bootable USB disk can help you fix issues when your system becomes unbootable or inaccessible. To do this, you’d typically boot from the USB disk and use built-in tools like GRUB to repair the bootloader or fsck to check and repair file system errors.

File Access

If your system does become inaccessible and unresponsive beyond recovery, a bootable USB disk allows you to access and back up important files to another storage device. You can then reinstall the system and then transfer the important files back to the system.

Malware Scanning and Removal

Even Linux has malware. A bootable USB disk allows you to access a clean Linux environment, which you can use to detect and remove malware without directly interacting with the infected system. Typically, you can use a tool like ClamAV or a rootkit detection tool like chkrootkit or rkhunter to scan for malicious files on your system.
