What happened to NightOwl?
NightOwl was originally a simple, well-regarded macOS utility for scheduling dark mode. It was sold to TPE.FYI LLC in November 2022. By June 2023, version 0.4.5.4 shipped with a residential proxy SDK from Pawns.app embedded in the app. This SDK silently routed third-party internet traffic through users' Mac computers, effectively turning each machine into a node in a commercial proxy network - without informed consent.
Security researchers flagged the behaviour, and Apple responded by revoking NightOwl's code-signing certificate. The app can no longer be verified by macOS Gatekeeper, and users who still have it installed see security warnings when trying to launch it. Multiple reports on r/macapps documented the discovery, with users finding unexplained network traffic originating from the NightOwl process.
If NightOwl is still installed on your Mac, uninstall it immediately. The residential proxy SDK may still be routing traffic through your network. Remove the app from Applications, delete any associated launch agents, and check Activity Monitor for lingering processes. For a full removal guide, see Is NightOwl Safe on Mac?
The NightOwl scandal is a cautionary tale about what happens when free utility apps change ownership. With 82% of smartphone users now preferring dark mode (Gitnux, 2024) and 64.6% wanting automatic switching based on time of day (forms.app), the demand for dark mode scheduling is real. But the app you choose needs to be trustworthy. Here are five alternatives that are.
What are the best NightOwl alternatives for Mac?
1. Solace - $4.99, one-time purchase (recommended)
Solace is the most complete NightOwl replacement available. It covers everything NightOwl did - dark mode scheduling based on solar position or custom times - and adds features NightOwl never had: evening warmth (colour temperature control), wallpaper syncing between light and dark mode, and weather-aware switching that adapts your Mac's appearance to real-time local conditions.
What matters most for users fleeing NightOwl is safety. Solace collects zero user data. There is no analytics, no telemetry, no account system, and no server communication. Location data for weather and solar calculations is processed entirely on-device using native macOS APIs. The business model is a one-time $4.99 purchase - no subscription, no ads, and no incentive to monetise user behaviour.
Key features include:
- Dark mode scheduling - solar, custom times, or weather-based
- Evening warmth - colour temperature reduction using native macOS APIs
- Wallpaper syncing - different wallpapers for light and dark mode
- Weather-aware switching - adapts appearance to real-time conditions
- Global keyboard shortcut - toggle everything instantly
- Multi-display support - consistent behaviour across all monitors
- Zero data collection - fully on-device, no network calls

2. macOS Auto Appearance - free, built-in
Every Mac running macOS Mojave or later has dark mode scheduling built in. Go to System Settings > Appearance > Auto, and your Mac will switch between light and dark mode at sunrise and sunset based on your location. No third-party app required, no data collection, no trust required.
The limitation is flexibility. Auto Appearance only supports solar-based switching. You cannot set custom times (like dark mode at 6pm regardless of sunset), you cannot trigger based on weather, and you cannot sync wallpapers. If sunset-and-sunrise scheduling is all you need, this is the safest possible option - it is part of the operating system itself.
3. Nightfall - free
Nightfall is a lightweight, free macOS app that adds dark mode scheduling with custom time ranges. It sits in the menu bar and lets you toggle between light and dark mode manually or on a schedule. It is a good step up from macOS Auto Appearance if you want custom times without paying for a full-featured app.
Nightfall's limitations are feature depth. There is no colour temperature control, no wallpaper syncing, no weather awareness, and no keyboard shortcut. It does the scheduling job and not much else. But it does it safely and for free.
4. f.lux - free
f.lux is a cross-platform colour temperature app that shifts your screen towards warmer tones after sunset. It has been around since 2009 and predated Apple's Night Shift by seven years. The current version is 42.2, released in September 2024.
f.lux is not a direct NightOwl replacement because it does not control dark mode at all. It only adjusts colour temperature. If you specifically need dark mode scheduling, f.lux cannot help. It also runs as a user-space daemon with 1.8–4.2% sustained CPU usage, compared to less than 0.3% for Apple's built-in Night Shift. The f.lux privacy policy states it collects geolocation data and usage information. For a detailed comparison, see Solace vs f.lux.
5. Shifty - free, open source
Shifty is a free, open-source macOS app that enhances Apple's built-in Night Shift. It adds per-app control (disable Night Shift for specific apps), a custom schedule override, and quick toggle options from the menu bar. Being open source means anyone can inspect the code - there are no hidden SDKs or proxy networks.
Shifty's scope is narrow. It only controls Night Shift, not dark mode. There is no dark mode scheduling, no wallpaper syncing, and no weather awareness. It pairs well with macOS Auto Appearance (Shifty handles Night Shift, Auto Appearance handles dark mode) but cannot replace NightOwl on its own.
How do NightOwl alternatives compare on safety?
After the NightOwl scandal, safety and data collection policies should be the first thing you evaluate in any replacement app. The average person spends 7 hours and 2 minutes per day looking at screens (DemandSage, 2026), and a dark mode app runs continuously in the background during all of that time. You need to trust what it is doing.
The comparison table below covers features, privacy, and safety across all five alternatives and NightOwl itself.
| Feature | Solace | Auto Appearance | Nightfall | f.lux | Shifty |
|---|---|---|---|---|---|
| Dark mode scheduling | Solar, custom, or weather | Solar only | Custom times | Not supported | Not supported |
| Colour temperature | Evening warmth (native APIs) | Not supported | Not supported | 1200K–6500K, 3 periods | Night Shift enhancement |
| Wallpaper syncing | Light/dark wallpapers | Not supported | Not supported | Not supported | Not supported |
| Weather-aware switching | Real-time conditions | Not supported | Not supported | Not supported | Not supported |
| Keyboard shortcut | Global shortcut | Not supported | Not supported | Not supported | Not supported |
| Data collection | None - fully on-device | None (built-in) | None | Geolocation + usage data | None (open source) |
| Code auditable | No (native macOS APIs only) | No (Apple proprietary) | No | No | Yes (open source) |
| Apple code-signed | Yes | Yes (built-in) | Yes | Yes | Yes |
| CPU impact | Minimal (native APIs) | Negligible | Minimal | 1.8–4.2% sustained | Minimal |
| Price | $4.99 one-time | Free (built-in) | Free | Free | Free |
| Actively maintained | Yes (2026) | Yes (Apple) | Limited updates | Last update Sept 2024 | Limited updates |
Every alternative in this table is safer than NightOwl. None of them embed proxy SDKs, and all except f.lux collect zero user data. The key differences are feature depth and how much you want to automate.
Which NightOwl alternative is right for you?
The right choice depends on what you actually need from a dark mode app. With 66% of computer users experiencing symptoms of computer vision syndrome (Journal of Optometry), getting your display settings right is not just about aesthetics - it affects your eye health and sleep quality over those 7+ hours of daily screen time.
Choose Solace if you want a complete NightOwl replacement with additional features NightOwl never had. Solace is the only alternative that combines dark mode scheduling, colour temperature, wallpaper syncing, and weather-aware switching in a single app. Zero data collection and a one-time $4.99 price make it the safest full-featured option.
Choose macOS Auto Appearance if you only need sunrise/sunset dark mode switching and do not want to install any third-party software. It is the most conservative, zero-risk option.
Choose Nightfall if you want free dark mode scheduling with custom times but do not need colour temperature or wallpaper features.
Choose f.lux if you specifically need colour temperature control across Mac, Windows, and Linux. Be aware it does not control dark mode and does collect some user data.
Choose Shifty if you want finer control over Apple's built-in Night Shift with per-app settings. Pair it with macOS Auto Appearance for a free dark mode + Night Shift setup.

Frequently asked questions
Is NightOwl still safe to download?
No. NightOwl version 0.4.5.4 (June 2023) embedded a residential proxy SDK from Pawns.app that routed third-party internet traffic through users' Macs without informed consent. Apple revoked NightOwl's code-signing certificate, and the app is no longer considered safe. If NightOwl is still installed on your Mac, you should uninstall it immediately and choose a safe alternative like Solace or macOS Auto Appearance.
What is the safest dark mode app for Mac?
Solace is the safest full-featured dark mode app for Mac. It collects zero user data, processes all location information on-device, has no analytics or telemetry, and uses only native macOS APIs. It is a one-time $4.99 purchase with no subscription and no account system. For a free option, macOS Auto Appearance is built into the operating system and requires no third-party code at all.
Does macOS have built-in dark mode scheduling?
Yes. macOS includes Auto Appearance, which switches between light and dark mode at sunrise and sunset based on your location. You can enable it in System Settings > Appearance > Auto. However, it only supports solar-based scheduling. You cannot set custom times, use weather-based switching, or sync wallpapers with the built-in option. For those features, you need a third-party app like Solace.
Does Solace collect any data?
No. Solace collects zero user data. There is no analytics, no telemetry, no account system, and no server communication. Location data for weather and solar calculations is processed entirely on-device using native macOS APIs. Solace is a one-time purchase with no subscription, so there is no incentive to monetise user data.
Can I get NightOwl's features for free?
Partially. macOS Auto Appearance provides free sunset and sunrise dark mode switching. Nightfall adds free scheduling with custom times. Shifty enhances Night Shift for free. But none of these free options match NightOwl's full feature set individually. Solace ($4.99 one-time) is the closest replacement, combining dark mode scheduling, colour temperature control, wallpaper syncing, and weather-aware switching in a single app with zero data collection.
