Best flight simulators for Mac compared: X-Plane 12, Aerofly FS 4 and free FlightGear, with MacBook, iMac and Apple silicon advice.
For general desktop flight simulation, MacBook, iMac and Apple-silicon owners should choose X-Plane 12 for the best overall experience, Aerofly FS 4 for easier, lighter use, or FlightGear for the best free option. The right choice depends on the Mac’s chip, memory, display resolution and desired aircraft, scenery and plugins.
The best Mac flight simulators compared
X-Plane 12 is the strongest long-term platform, while Aerofly FS 4 prioritises straightforward flying and FlightGear provides a complete simulator without a purchase.
| Simulator | Choose it when | Mac strengths | Main compromise |
|---|---|---|---|
| X-Plane 12 | You want serious civil aviation, IFR, airliners or extensive add-ons | Official macOS support, detailed flight modelling, weather and a mature aircraft and scenery ecosystem | The most demanding option; older plugins require checking on Apple silicon |
| Aerofly FS 4 | You value quick loading, accessible controls and less configuration | Official Mac version, polished presentation and generally lighter setup | Fewer third-party aircraft, airports and specialist utilities than X-Plane |
| FlightGear | You need a genuinely free desktop flight simulator | Free and open source, with navigation, weather and many community aircraft | Aircraft quality varies, and setup is less consistent or polished |
Flight simulator on a MacBook or iMac: what will run?
All three simulators can run on suitable Macs, but a Mac’s family name or screen size does not reveal its performance.
| Mac type | Likely suitability | Practical expectation | Main limitation to check |
|---|---|---|---|
| Apple-silicon MacBook Air | X-Plane 12, Aerofly FS 4 and FlightGear, subject to supported macOS versions | Aerofly is the easiest starting point; X-Plane needs restrained resolution and scenery settings on entry-level models | Models with 8 GB unified memory have less room for complex aircraft and scenery; the fanless design can reduce sustained performance during long sessions |
| Apple-silicon MacBook Pro | All three, with X-Plane the best use of stronger configurations | Well suited to detailed aircraft and larger displays when fitted with adequate memory and GPU capacity | MacBook Pro configurations vary widely, so the name alone does not indicate graphics performance |
| Current Apple-silicon iMac | All three official Mac options | A good fixed-desktop choice, but begin below the display’s full native resolution | The high-resolution built-in display can create a much heavier GPU load than expected |
| Older Intel Mac with discrete graphics | Potentially suitable if the GPU, macOS release and simulator version remain supported | Moderate settings may work, particularly with simpler aircraft and weather | Ageing graphics drivers, limited video memory and unsupported macOS versions |
| Older Intel Mac with integrated graphics | FlightGear or less demanding simulator versions at reduced settings | Use a demo where available and expect low resolution, modest scenery and simple aircraft | Integrated graphics and shared system memory can make X-Plane 12 or dense scenery impractical |
Our hardware-specific MacBook Air guidance covers the extra compromises created by fanless cooling, entry-level memory and compact displays.
Is a “25-inch iMac” description enough?
No. A screen description such as “25-inch iMac” is not enough to judge compatibility, and sellers sometimes round the measured diagonal. Macs with similar-looking displays can have completely different processors, graphics hardware and macOS limits.
Open the Mac’s system information and record the exact model year, Apple chip or Intel processor, GPU, installed memory, macOS version and available storage. Compare those details with the simulator’s requirements. Also confirm whether an Intel iMac has integrated or discrete graphics; that distinction can matter more than its screen size.
What performance should you expect from a Mac flight simulator?
A realistic starting point depends on memory and graphics capacity, but no Mac should begin with every setting maximised at its panel’s native Retina resolution.
| Mac capability | Sensible starting resolution | Starting settings | Suitable workload |
|---|---|---|---|
| Constrained: 8 GB Apple silicon, older Intel integrated graphics or a low-memory GPU | About 1080p rather than native Retina or 4K | Low-to-medium clouds and objects, limited traffic, shadows disabled or reduced | Simple general-aviation aircraft, fair weather and less dense airports |
| Mid-range: Apple silicon with 16 GB memory and a capable GPU, or a supported Intel Mac with useful discrete graphics | About 1440p, or a scaled internal-display setting below native | Medium-to-high textures, moderate clouds and objects, conservative shadows | Airliners and detailed airports after individual tuning |
| High-spec: stronger Apple-silicon GPU configurations with more than 16 GB memory | Start at 1440p and work towards 4K only if demanding situations remain smooth | High settings selectively rather than every option at maximum | Complex aircraft, heavier weather and dense scenery with fewer compromises |
On a Retina MacBook or iMac, start one or two output-resolution steps below the panel’s native resolution. For an external 4K or higher display, begin around 2560×1440 on a mid-range Mac or around 1920×1080 on constrained hardware. At the same settings, 4K requires the GPU to shade four times as many pixels as 1080p and 2.25 times as many as 1440p.
A mistake we see constantly is increasing texture quality, anti-aliasing, clouds, shadows and world detail together. Change one group at a time and test at a dense airport, in cloudy weather and inside the aircraft you actually intend to fly.
- Lower resolution and anti-aliasing first when GPU-limited. Anti-aliasing is less valuable on a dense Retina display, and reducing output resolution usually produces the clearest graphics saving.
- Reduce shadows, reflections and cloud quality next. These effects can consume substantial graphics time, especially in poor weather or near detailed airports.
- Reduce world objects and traffic when the processor is the limit. AI aircraft, road traffic, parked aircraft and dense buildings create work that resolution changes may not fix.
- Lower textures when memory is exhausted. Texture reductions help when detailed scenery and cockpits cause stutters, long pauses or heavy memory pressure.
With 8 GB unified memory, macOS, the simulator, the CPU and the GPU all draw from the same pool. A complex airliner, detailed airport and cloud layer can force memory compression or storage swapping. Older Intel integrated graphics have a similar shared-memory problem, usually with much less graphics performance.
Why is X-Plane 12 the best flight simulator for most Mac users?
X-Plane 12 offers the best combination of official macOS support, flight modelling, instrument procedures, weather and long-term expansion.
It covers general aviation, airliners and helicopters without needing Windows. Its main advantage over simpler Mac flight sims is the supply of aircraft, airports, scenery, liveries and utilities; our freeware X-Plane aircraft and scenery library shows the range available.
Use the official X-Plane demo before purchasing. Run it at the resolution and display arrangement you plan to use, connect your controls and test demanding weather rather than judging performance from an empty runway. The demo establishes whether the base simulator works, but it cannot guarantee that a complex third-party aircraft or plugin will perform well.
When is Aerofly FS 4 the better Mac flight sim?
Aerofly FS 4 is the better choice when uncomplicated installation, short loading times and accessible flying matter more than add-on depth.
It works particularly well for sightseeing, general aviation and users who do not want to manage numerous plugins or scenery packages. Calling it lighter does not mean every old Intel Mac will run it well; its exact system and macOS requirements still apply.
Choose X-Plane instead if you expect to reproduce detailed airline operations, install specialist utilities or build a large aircraft and airport collection. Aerofly’s smaller ecosystem is simpler to manage, but it gives you fewer ways to expand the simulator later.
What is the best free flight simulator for Mac?
FlightGear is the best fully free desktop flight simulator for Mac because it is a complete open-source programme rather than a restricted trial.
There is no purchase required and no demo expiry. It supports navigation, instrument flight, weather and a broad aircraft selection, although individual community aircraft range from basic external models to detailed cockpits and systems.
- FlightGear is genuinely free. The desktop simulator remains usable without buying a full edition.
- The X-Plane demo is not the free version of X-Plane. It is a time-limited and restricted compatibility test; continued unrestricted flying requires the full simulator.
- Browser simulators may have free tiers. They avoid a large installation, but require an internet connection and usually offer less systems depth, scenery control and peripheral support than a desktop simulator.
- Cloud streaming is not automatically free. A streamed commercial simulator may still require an account, subscription or game entitlement.
Our comparison of no-cost Mac flight simulators also covers browser flying, combat-oriented choices and simpler alternatives for less powerful hardware.
Does Microsoft Flight Simulator run on Mac?
Neither Microsoft Flight Simulator 2020 nor Microsoft Flight Simulator 2024 has a native macOS version.
MSFS 2024’s releases on Windows, Xbox Series X|S and PlayStation 5 or PS5 Pro do not include Mac support; MSFS 2020 remains a PC and Xbox release. A virtual machine or Windows compatibility layer is not a dependable substitute for a native build because the simulator relies on demanding graphics features, drivers, copy protection and peripheral software.
There are three practical alternatives, each with limits:
- Cloud play through a supported browser may work when the chosen Microsoft Flight Simulator release appears in the service’s catalogue and the service operates in your region. Expect to need a Microsoft account and the relevant subscription or entitlement.
- Remote streaming from your own Windows gaming PC keeps the simulator and add-ons on the host computer. The Mac receives compressed video and sends control inputs, so the host must remain switched on and configured.
- Boot Camp applies only to Intel Macs. It can install Windows directly on a compatible Intel model, but the Mac must still satisfy the simulator’s Windows graphics, memory and storage requirements. Boot Camp is unavailable on Apple silicon.
Cloud and remote play depend on latency, jitter and connection stability, not just headline download speed. Image compression can blur glass-cockpit text, while a brief network interruption can affect control inputs. A wired network connection usually gives more consistent results than congested Wi-Fi.
Peripheral support is the larger obstacle for serious flying. A gamepad may work while USB yokes, pedals, throttles and proprietary panels fail to appear through the browser or streaming layer. Cloud sessions also do not provide normal access to a local Community folder. If those restrictions rule out MSFS, our comparison of native Microsoft Flight Simulator alternatives explains how X-Plane, Aerofly and FlightGear differ.
Will flight simulators and add-ons work on an Apple-silicon Mac?
Major Mac simulators can support Apple silicon, but every binary aircraft plugin, utility and hardware driver must be checked separately.
- Prefer universal or native Apple-silicon plugins. A universal binary contains compatible Apple-silicon code as well as Intel code; a native plugin can run while the simulator uses its Apple-silicon executable.
- Identify Rosetta-dependent Intel plugins. An Intel-only aircraft plugin may require the whole simulator to run through Rosetta. The aircraft can appear normally while its displays or systems fail because the embedded plugin did not load.
- Reject 32-bit components. Modern macOS releases cannot load legacy 32-bit plugin code, and Rosetta does not repair that incompatibility.
- Match the simulator generation. Check whether an aircraft, scenery package or plugin was made for the installed simulator version. An X-Plane 11 add-on is not automatically compatible with X-Plane 12 merely because both use similar folder structures.
- Approve Gatekeeper warnings individually. Only approve a blocked component after confirming its source and stated Mac support. Use macOS’s security controls for that specific item; do not disable Gatekeeper globally or remove security attributes from an entire downloads folder.
For X-Plane, Log.txt in the simulator folder is the first place to check when an aircraft loads without working displays or a plugin menu is missing. It can reveal an incompatible architecture, missing dependency or plugin-loading failure.
What should you check before installing a flight simulator on macOS?
Confirm the exact hardware, operating system, storage needs and controller support before building an add-on collection.
- Record the complete Mac specification. Check the model year, Apple chip or Intel CPU, GPU, memory and macOS release rather than relying on labels such as MacBook Pro or 25-inch iMac.
- Verify operating-system support. An older Mac may be fast enough but unable to install the required macOS version; an older simulator may have the opposite problem on a newer system.
- Leave storage for extraction and updates. Detailed scenery and airports can exceed the base simulator’s footprint. Keep working space available during installation rather than filling the drive to its capacity.
- Check every controller and utility. Standard USB controls can often be assigned inside the simulator, but proprietary panels may depend on Windows-only drivers. Underpowered hubs and adaptors can also cause intermittent disconnections.
- Inspect external-drive formatting. Some older add-ons assume the standard case-insensitive Mac file system and fail on a case-sensitive volume because folder or file names do not match exactly.
- Test the demanding case. Judge performance with clouds, a detailed airport and cockpit instruments visible. Smooth flight over an empty rural area does not prove the Mac can handle an airliner at a major airport.
