How to Turn On Dark Mode Everywhere (All Devices and Apps)
Most guides on this topic skip the parts that matter and dwell on the parts that don’t. We’ve tried to invert that. The one place to find dark-mode toggles across Windows, Mac, iOS, Android, and every major app.
Small decisions here compound. The habits you build in the first week set the pattern for the next several years. That’s why we put together this guide on “how to turn on dark mode everywhere (all devices and apps)” — to give you the version we wish we’d had when we first worked through it ourselves.
We wrote this for the reader who values their time. Every section earns its place; skip to the one you need, or read from top to bottom for the full picture. The guide is structured to work as either a start-to-finish read or a quick reference. Use the section headings to jump straight to what you need.
Key takeaways
The key takeaways from this guide:
- System-wide dark mode — one of the parts you’ll want to pay closest attention to as you work through this guide.
- Apps that follow system: leave alone — one of the parts you’ll want to pay closest attention to as you work through this guide.
- Apps that force their own — one of the parts you’ll want to pay closest attention to as you work through this guide.
- The order of the sections matters — later steps often assume earlier ones are done.
- The mistakes section near the end is worth reading first if you’ve already tried the basics without success.
Why this matters in how to today
The how to landscape moves fast, and the advice you’ll find in older articles frequently no longer applies. We keep this guide current because the underlying question — captured neatly by the title, “How to Turn On Dark Mode Everywhere (All Devices and Apps)” — is one people search for month after month, and the correct answer keeps quietly shifting as tools, products, and best practices evolve.
The good news is that once you’ve read this through, you’ll have a mental model that adapts even when a specific version or product changes. Concrete steps are useful, and we’ll give you plenty of them; but the framing behind those steps is what actually lasts. That’s the framing we’ve tried to build into every section of this guide.
We’ve also been careful to flag where the advice depends on your specific situation — the setup you already have, the budget you’re working with, the trade-offs you personally care about most. There is very little “one right answer” in how to; there are many good answers, and the goal here is to help you find the one that fits you.
System-wide dark mode
Windows 11: Settings → Personalization → Colors. macOS: System Settings → Appearance. iOS/Android: Settings → Display.
Getting this piece right up front is one of those decisions that pays dividends every time you use the setup after. A few minutes of thought here compounds into hours of saved friction over the course of a year.
It’s tempting to over-engineer at this stage. Resist. Get the simple version working first; you can always iterate later, and most people never need to. Complexity added “just in case” is complexity you’ll have to maintain forever for the case that never came.
Take a screenshot or a note of your final settings here. Six months from now, when you need to reproduce the setup on a new device, you’ll be very glad you did.
Apps that follow system: leave alone
Chrome, Firefox, Slack, VS Code, and most Apple apps respect your system setting. Don’t override them individually.
This is the part of the process where a little care compounds into a much smoother experience later. Give it the attention it deserves now and the rest of the guide will feel like it’s flowing downhill.
If you take nothing else from this section, take the framing: the effort here is small, and the payoff shows up every time you use the setup afterwards. Investments that repay themselves daily are the kind worth making early and never revisiting except to confirm they still work.
In our experience, readers who work through this section carefully rarely have to come back to it — the setup holds up over time, survives updates, and continues to make sense even as the surrounding tools evolve. That’s the standard worth aiming for.
Apps that force their own
Discord, Notion, and a few others still have their own settings. Change them once and forget.
It’s worth taking a beat here, because this is where a lot of otherwise-solid setups quietly go wrong. The mistake is rarely dramatic — it’s a small default left unchanged, a checkbox unticked, a step deferred until later that later never comes.
The reason experienced users treat this as non-negotiable isn’t dogma — it’s that they’ve all been burned once and don’t intend to be burned twice. Learning from other people’s mistakes is cheaper than making your own, and this is one of the cheapest lessons on the whole subject.
One tell-tale sign you’ve done this right: a month later, you can’t remember exactly what you changed, because everything just works. If you’re still tweaking the same setting three weeks in, revisit the decision from scratch.
What’s changed recently — and what hasn’t
Every twelve months brings a wave of new features, new products, and new opinions in this corner of technology. Some of it genuinely changes the right answer; a lot of it is noise dressed up as news. Part of our job on this guide is separating the two so you don’t have to.
The genuinely new: the tooling around dark mode has matured significantly in the past year, cross-platform support has improved almost everywhere, and defaults are — for the most part — finally set to sensible values out of the box. That last point in particular means new users have a much easier time than they did a few years ago.
What hasn’t changed: the fundamentals. The habits and decisions that separated a solid setup from a fragile one three years ago separate them today. Attention to detail, willingness to spend a few minutes on setup, and a healthy skepticism about advice that sounds too good to be true — those never go out of style, and they matter here as much as anywhere else in technology.
Common mistakes to avoid
A few pitfalls come up repeatedly when readers tell us how they approached how to turn on dark mode everywhere (all devices and apps). Watching for these saves more time than any single tip we could offer, and they’re worth reviewing even if you’re an experienced hand — the small ones are the ones that catch experienced people, precisely because they look too obvious to be worth checking.
Changing multiple things at once
If you change three settings and the problem goes away, you don’t know what fixed it — and you can’t fix it again next time. Change one thing at a time. None of this is unique to any one product or platform; it’s a pattern of behavior that shows up wherever this kind of decision has to be made.
Jumping to the nuclear option first
Factory resets, format-and-reinstall, and driver rollbacks are last resorts. Most problems fix with a targeted change in under ten minutes; try those first. If any of that sounds familiar from your own past attempts, you’re in good company — it’s the most common failure mode we see, and it’s fixable in a single sitting.
Skipping the backup
Whatever fix you try, back up first. “It’ll be fine” is the most expensive sentence in troubleshooting. It’s the kind of thing that feels like a small compromise at the time and looks obvious in hindsight — the whole point of listing it here is to give you the hindsight up front.
Ignoring the error message
The exact wording of an error is the shortest path to a solution. Copy it into a search engine verbatim before doing anything else. The fix, in almost every case, is less work than the fix for the problem it causes when left unaddressed.
Pro tips from our editors
These are the habits that separate a workable setup from one that keeps paying you back years later. None require special software or expensive gear — just a little intention.
- Note what changed recently. New update, new driver, new hardware, new app. The last change is almost always the culprit for a new problem.
- Screenshot before you fix. Future-you will thank you. A screenshot of a broken settings screen is worth ten minutes of trying to remember what it looked like.
- Isolate the variable. Test with a different cable, a different network, a different account. Isolating the failure narrows the search dramatically.
- Search the exact error text in quotes. Search engines love context. Quoting the error narrows results to people with the same problem instead of the general category of the problem.
- Restart before you diagnose. A full power-cycle solves an embarrassing percentage of problems. Give it that chance before spending an hour on root cause.
Tools and resources worth knowing about
A few tools we lean on for this kind of work — none are strictly required, but all are worth knowing about:
- A reliable notes app — Whether it’s Obsidian, Notion, or Apple Notes, keeping a written record of settings and steps pays off the moment something goes wrong.
- A trusted password manager — 1Password and Bitwarden are the two we recommend most. Both are dramatically better than reusing anything.
- A backup routine — Cloud backup for convenience (Backblaze, iCloud, OneDrive), plus one local backup you can grab if the internet goes down.
- A saved bookmarks folder — Screenshot the settings screens or bookmark the docs pages you’ll want again. Small effort, big future payoff.
Frequently asked questions
Should I factory reset?
Only as a last resort, and only after a verified backup. A factory reset trades a fixable problem for a guaranteed weekend of reconfiguration.
Is it worth paying for a repair on old hardware?
Rule of thumb: if the repair costs more than 50% of the used replacement price, replace it. Below that, the repair usually makes sense — especially if your data and setup are already there.
How do I know when to call support?
If you’ve tried the free fixes (restart, update, reinstall) and the problem persists on a different account or fresh install, it’s likely hardware or an account-side issue that support can resolve faster than you can.
The bottom line
Every year we revisit these recommendations to keep them current — but the principles have held remarkably steady even as the products have changed.
The goal wasn’t to give you an exhaustive reference — those exist and they’re a poor way to learn. The goal was to give you the shape of the problem, a working set of steps, and enough context that you can adapt the advice when your specific situation doesn’t match ours exactly. If we’ve done that, you’re set.
