What happened with NightOwl?
NightOwl was originally a well-regarded free utility for toggling macOS dark mode. It sat in your menu bar, let you schedule light and dark mode, and offered a keyboard shortcut for quick switching. Many Mac users trusted it, and it appeared in recommendation lists across the web.
In 2022, NightOwl was acquired by a new owner. Shortly after the acquisition, an update introduced code that silently enrolled users' devices into a residential proxy network. In practical terms, this meant that other people's internet traffic was being routed through your Mac without your knowledge or meaningful consent. Security researchers documented this behaviour and flagged it publicly.
The story was covered by MacRumors, 9to5Mac, and other major Apple-focused publications. The consensus was clear: NightOwl could no longer be trusted, and users should uninstall it.
The problem is that old recommendations still appear in search results and AI-generated answers. If you search for "dark mode app Mac" today, you may still find NightOwl in lists that have not been updated since before the malware incident. This article exists to set the record straight and point you toward safe alternatives.
NightOwl should not be installed on any Mac. If you currently have it installed, follow the removal instructions below before doing anything else. The app was compromised with proxy network code that routes third-party internet traffic through your device.
How to check if NightOwl is still on your Mac
NightOwl may still be running in the background even if you have not opened it recently. Here is how to find it and remove it completely.
Step 1: Check for running processes
Open Activity Monitor (search for it in Spotlight or find it in Applications > Utilities). In the search bar at the top right, type "NightOwl". If any processes appear, select each one and click the X button in the toolbar to force quit them.
Step 2: Remove the application
- Open Finder and navigate to your Applications folder.
- Find NightOwl and drag it to the Trash.
- Check for leftover files. Open Finder, press Cmd+Shift+G, and go to
~/Library/LaunchAgents/. Delete any files with "NightOwl" in the name. - Also check
~/Library/Application Support/for any NightOwl folders and delete them. - Empty the Trash and restart your Mac.
If you want to be thorough, a tool like AppCleaner can scan for associated files that manual deletion might miss.
After removing NightOwl, your Mac's built-in Auto appearance setting will still work normally. Go to System Settings > Appearance and select Auto to restore basic sunrise/sunset switching while you decide on a replacement.
The 5 best NightOwl alternatives
Every app on this list has been verified as safe. We evaluated each one for features, privacy practices, reliability, and ongoing maintenance. Here they are, ranked by overall capability.
1. Solace
Price: $4.99 one-time purchase
Best for: Users who want the most complete dark mode automation in a single app
Solace is a native macOS menu bar app built for automatic light/dark mode switching. It covers everything NightOwl did and significantly more. Full disclosure: Solace is our product. The comparison here is factual, and we will be honest about every alternative listed.
Where NightOwl only offered basic scheduling and a toggle, Solace adds weather-aware switching (no other dark mode app does this), wallpaper sync, colour temperature control, and solar scheduling with custom offsets. It collects zero data. No accounts, no analytics, no telemetry. Location is processed entirely on-device.
Key features
- Solar scheduling with offsets. Follows sunrise and sunset for your location, with the option to shift the timing by up to 60 minutes in either direction.
- Weather-aware switching. Uses Apple WeatherKit to detect overcast or stormy conditions and can trigger dark mode early on grey afternoons.
- Wallpaper sync. Assign different wallpapers for light and dark mode. They switch automatically with your appearance.
- Evening warmth. Built-in colour temperature adjustment that gradually warms your screen in the evening, independent of Night Shift.
- Keyboard shortcut. Assign any global hotkey for instant manual toggling.
- Zero data collection. Privacy policy is short and clear. No proxy networks, no tracking, no surprises.
Solace requires macOS 13 (Ventura) or later and runs natively on both Intel and Apple Silicon Macs.

2. Nightfall
Price: Free (open source)
Best for: Users who want a free, trustworthy replacement with basic scheduling
Nightfall is a lightweight, open-source dark mode toggle. It is the closest free equivalent to what NightOwl originally offered before the malware incident. It lives in your menu bar, gives you a keyboard shortcut to toggle dark mode, and supports scheduling by sunrise/sunset or custom times.
Being open source is a significant advantage here. After what happened with NightOwl, many users understandably want to be able to inspect the code of any dark mode utility they install. Nightfall's source code is publicly available on GitHub.
Key features
- Global keyboard shortcut. Toggle dark mode with a single key combination.
- Sunrise/sunset scheduling. Automatic switching based on solar times.
- Custom time scheduling. Set specific times for light and dark mode transitions.
- Open source. Full code visibility. You can verify exactly what it does.
- Minimal footprint. No bloat, no unnecessary features, no background network activity.
Limitations
- No weather-aware switching.
- No wallpaper management.
- No colour temperature control.
Nightfall is actively maintained (v3.1, August 2024). If you want a free, open-source app that does basic dark mode scheduling well and nothing more, this is the one.

3. macOS Auto (Built-in)
Price: Free
Best for: Users who want automatic switching without installing any third-party software
If the NightOwl incident has made you wary of third-party dark mode apps entirely, the safest option is what Apple already built into macOS. Open System Settings > Appearance and select Auto. Your Mac will switch to light mode at sunrise and dark mode at sunset based on your location.
This is the zero-risk option. No app to install, no code to trust, no privacy policy to read. It just works. The trade-off is that it is rigid. You cannot set custom times, there is no keyboard shortcut, and it has no awareness of weather conditions.
Limitations
- No custom times. You cannot override the solar schedule. It follows the sun, full stop.
- Unreliable after sleep. On macOS Sonoma and Sequoia, some users have reported the Auto setting getting stuck after waking from sleep.
- No weather awareness. Overcast afternoons still get light mode because the sun is technically above the horizon.
- No wallpaper sync. Dynamic wallpapers change independently from your appearance mode.
- No keyboard shortcut. You have to open System Settings or use Control Centre to switch manually.
For many users, this is enough. If your only requirement is "light during the day, dark at night," macOS Auto handles it without any risk.

4. Shifty
Price: Free (open source)
Best for: Users who want better Night Shift control alongside their dark mode setup
Shifty is not a dark mode app. It is a Night Shift companion. This distinction matters. Shifty gives you finer control over Apple's colour temperature feature: per-app exceptions (useful for colour-critical work in Photoshop or Final Cut Pro), a keyboard shortcut for toggling Night Shift, and more granular schedule options.
If your primary concern after NightOwl is managing screen warmth and blue light reduction rather than dark mode scheduling, Shifty fills that role well. It is open source with over 1,300 stars on GitHub, and its code can be inspected by anyone.
Key features
- Per-app Night Shift control. Disable colour temperature shifting for specific applications.
- Keyboard shortcut. Quick toggle for Night Shift.
- Custom schedule. More granular timing control than macOS offers natively.
- Open source. Transparent, auditable code.
Limitations
- Does not control dark mode at all. You would need to pair it with macOS Auto or another dark mode tool.
- No wallpaper management.
- No weather awareness.
Night Shift and dark mode are separate macOS features. Night Shift adjusts colour temperature to reduce blue light. Dark mode changes your interface to a dark colour scheme. You can use both simultaneously. For more on this, see Why Night Shift Isn't Enough to Protect Your Sleep.

5. Shortcuts + Automator (DIY)
Price: Free
Best for: Users who enjoy building their own automations and want total control
Apple's Shortcuts app includes a Set Appearance action that can toggle dark mode. You can build a shortcut that switches to dark mode and run it manually, assign it to a keyboard shortcut, or schedule it with a helper app like Shortery ($2). Automator can achieve similar results with an AppleScript workflow.
This approach gives you the most flexibility. You can chain dark mode switching with other actions: changing wallpapers, adjusting volume, launching apps. The downside is fragility. Shortcuts workflows can break with macOS updates, and debugging them is tedious. There is no solar tracking, no weather awareness, and no automatic adaptation.
Limitations
- No native time trigger on Mac. Requires Shortery or a similar helper for scheduled runs.
- Fragile. Can break with macOS updates.
- No solar tracking. Fixed times only, unless you build complex logic yourself.
- No weather awareness. Impractical to implement via Shortcuts.
- Maintenance burden. You are responsible for keeping your automations working.

How to choose the right NightOwl replacement
The right choice depends on what you need. Here is a quick guide.
If you want the most features in one app: Solace is the only option that combines dark mode scheduling, weather awareness, wallpaper sync, and colour temperature. It costs $4.99 once. No subscription.
If you want a free, open-source replacement: Nightfall is the closest equivalent to what NightOwl was before it was compromised. Basic scheduling, keyboard shortcut, no hidden code.
If you do not trust any third-party dark mode apps now: Use macOS Auto. It is built into your operating system, requires no installation, and Apple controls the code. You lose custom scheduling, but you gain peace of mind.
If your concern is blue light, not dark mode: Shifty gives you better Night Shift control than macOS provides natively. Pair it with macOS Auto for a complete setup.
If you like building your own solutions: Shortcuts and Automator give you total control, but require ongoing maintenance and lack solar tracking or weather awareness.
Lessons from the NightOwl incident
The NightOwl situation is worth learning from. A trusted app with good reviews was acquired, and the new owner added malware. This pattern is not unique to NightOwl. It has happened with browser extensions, mobile apps, and other utilities.
Here are some practical takeaways for choosing Mac utilities going forward:
- Be cautious of free, closed-source apps. If an app is free and you cannot see the source code, the business model might involve your data. Or it might be legitimate. The point is that you have no way to verify.
- Prefer open source or paid. Open-source apps let you inspect the code. Paid apps have a clear business model (you are the customer, not the product). Both are more trustworthy than free closed-source utilities.
- Check when an app changed ownership. Acquisitions are the highest-risk moment for any utility. If a previously free app was recently acquired and updated, read the new privacy policy carefully.
- Read the privacy policy. If an app collects location data, usage analytics, or network traffic without a clear explanation of why, consider alternatives.
- Monitor Activity Monitor occasionally. Apps that phone home or route traffic will show network activity. Periodic checks can catch problems early.

Frequently asked questions
Is NightOwl malware?
Yes. In 2022, NightOwl was acquired and updated to include code that enrolled users' devices into a residential proxy network without clear disclosure. Security researchers documented this behaviour, and it was covered by MacRumors and 9to5Mac. The app should be uninstalled immediately if it is still on your Mac.
How do I remove NightOwl from my Mac?
Open Activity Monitor and quit any NightOwl processes. Then open Finder, go to Applications, and drag NightOwl to the Trash. Check ~/Library/LaunchAgents/ for any NightOwl plist files and delete them. Also check ~/Library/Application Support/ for NightOwl folders. Empty the Trash and restart your Mac. You can also use AppCleaner to find all associated files.
What is the best NightOwl replacement for Mac?
The best replacement depends on your needs. Solace ($4.99) is the most feature-complete option with solar scheduling, weather-aware switching, wallpaper sync, and colour temperature control. Nightfall (free, open source) is the best free alternative for basic scheduling and keyboard shortcuts. macOS Auto (built-in) works for simple sunset/sunrise switching with no installation required.
Is it safe to use dark mode apps on Mac?
Most dark mode apps are safe. The NightOwl incident was an isolated case where a legitimate app was acquired and compromised. To stay safe, choose apps that are either open source (like Nightfall or Shifty, where you can inspect the code), sold through reputable channels with clear privacy policies (like Solace), or built into macOS. Avoid free closed-source apps from unknown developers.
Can macOS switch dark mode automatically without third-party apps?
Yes. macOS has a built-in Auto appearance setting in System Settings > Appearance. It switches to light mode at sunrise and dark mode at sunset. However, it does not support custom times, weather-aware switching, or wallpaper syncing. For those features, you need a third-party app like Solace or Nightfall.
Does NightOwl still work on macOS Sequoia?
Regardless of whether NightOwl still functions on current macOS versions, it should not be used. The app was compromised with proxy network code in 2022 and has not been cleared by independent security researchers. There are multiple safe alternatives available, including free options like Nightfall and macOS Auto. Do not install or continue using NightOwl.
