MetaTrader on Mac and iPhone: what actually works

The short version

MetaTrader exists on almost everything. Automation exists on one thing. The apps for iPhone, iPad, Android and macOS are real, official and free, and none of them will run an expert advisor.

Why mobile cannot do it

An expert advisor is a compiled program that runs *inside* the MetaTrader terminal. The desktop terminal ships an MQL runtime to execute it. The mobile apps do not include that runtime at all, so there is nothing for the EA to run in.

This is not a setting, a permission or a paid tier, and no broker has a special build that changes it. Both iOS and Android restrict third-party code execution in ways that make shipping an MQL runtime impractical, which is why no MT4 or MT5 mobile app from any provider runs expert advisors.

MetaTrader on a Mac: three routes

For manual trading, the native build is fine. For running an EA, the honest answer is Parallels or a VPS. A Wine layer can work and often does, but it introduces a second thing that can fail between your strategy and your broker, and diagnosing which one broke a trade at three in the morning is not a good use of anyone's time.

On Apple Silicon this matters more, not less. Emulation layers have improved but the MetaTrader terminal was written for x86 Windows, and it shows under load.

What you actually need

• ·A Windows machine that stays on. Awake, connected, terminal open, logged in. A laptop that sleeps stops the bot mid-position.
• ·Or a Windows VPS. A small always-on rented machine, typically a few dollars a month. This is what most people end up doing, and it is the standard answer for every MT5 bot rather than a quirk of ours.
• ·Your phone as a window, not an engine. The mobile app on the same account shows every position the EA opens, and lets you close one by hand if you want to.

Our own Mobile + PC plan includes the VPS for exactly this reason, and adds a web dashboard so the engine can be started and stopped from a phone — but the engine is still running on Windows, trading XAUUSDm, not on the handset. Anyone claiming otherwise is describing something else.

The uncomfortable conclusion

If you own only a Mac and an iPhone, and you are not willing to run Parallels or rent a VPS, you should not buy an MT5 expert advisor — from us or from anybody. It will not run, and no support ticket will change that.

That costs us a sale occasionally and it is still the right thing to say, because the alternative is a refund request three days later from someone who was told what they wanted to hear. If you are weighing bots generally, the seven-point evidence test covers what else to establish before paying, and what to know before your first bot covers the rest of the practical constraints.

And if the platform question is really a trust question, is MetaTrader 5 safe deals with that separately — the short answer being that the terminal is not where your risk is.
