:pencil: OpenMTP: My Honest Review

OpenMTP is a free, open-source app designed to make file transfers between Android devices and macOS easier. It was created as an alternative to the older Android File Transfer app from Google, which many users consider unreliable.

Based on discussions from multiple Reddit threads, OpenMTP generally leaves a positive impression, but it also has some recurring issues depending on device compatibility and file types.

:microscope: Interface and Ease of Use

One of the most frequently mentioned strengths of OpenMTP is its interface.

The app uses a dual-pane layout:

  • One side shows files on your Mac

  • The other shows files on your Android device

This setup makes file transfers feel similar to working with a traditional file manager. Drag-and-drop works reliably for most users, which simplifies tasks like copying photos, music, or documents.

Several Reddit users mention that this interface makes transfers far less frustrating compared with Android File Transfer, which is often described as slow and unstable.

:electric_plug:Transfer Performance

Many users report that OpenMTP performs well during normal transfers.

Common positives include:

  • Stable transfers for typical file sizes

  • Reasonable speed over USB

  • Support for transferring large files

  • The ability to queue multiple transfers

For everyday use – moving photos, media files, or backups – the app usually performs reliably. Compared to Android File Transfer, users often say it handles large files with fewer interruptions.

However, performance is not completely consistent across devices.

:optical_disk:Compatibility and Device Support

OpenMTP supports macOS Catalina and newer versions. Recent versions also improved compatibility with certain Android devices, including some Samsung models.

That said, compatibility is one of the more common sources of complaints.

Some users report that:

  • Their Android device is not detected

  • Transfers fail with certain devices

  • Specific MTP devices (such as digital audio players or e-ink devices) behave inconsistently

Because MTP support itself can vary across Android hardware, these issues are not always fully within the app’s control.

:low_battery:Common Issues Reported by Users

Despite the generally positive feedback, several recurring problems appear in Reddit discussions.

1. Transfer Freezes

Some users report transfers freezing halfway through, particularly when dealing with large files.

A frequent cause mentioned is file names containing unsupported characters.

2. Connection Problems

Occasionally the app fails to recognize a connected Android device. This issue sometimes resembles the same problems seen in Android File Transfer.

Enabling USB Debugging on the Android device can sometimes help.

3. Device-Specific Bugs

Certain devices simply appear to have inconsistent MTP behavior with the app. For example, some Samsung devices or specialized MTP devices have been reported to work inconsistently.

For users affected by these issues, switching to a different tool may be necessary.

:light_bulb:Tips for Better Results

Based on user suggestions:

  • Avoid special characters in file names when transferring files

  • Enable USB Debugging if connection problems occur

  • Use a reliable USB cable and port

  • Restart the app or reconnect the device if transfers freeze

These steps resolve many of the issues reported in community discussions.

↔️Alternatives to OpenMTP

If OpenMTP does not work well with a specific device, there are several alternatives worth considering.

MacDroid

MacDroid is a commercial macOS utility that mounts Android devices directly inside Finder.

Strengths

  • Integrates Android storage into Finder like an external drive

  • Supports USB and Wi-Fi connections

  • Allows copying entire folders easily

  • Can edit files on the Android device without copying them first

  • Supports SD cards and multiple storage locations

MacDroid tends to feel more integrated into macOS than OpenMTP, but the cost may be a drawback for some users.

NearDrop

NearDrop is an open-source app that brings Android’s Nearby Share functionality to macOS.

Strengths

  • Wireless transfers without cables

  • Very simple setup

  • Fast for sending photos, videos, or small files

  • Open source

It’s important to note that this app only supports Android → Mac transfers, so if you want to transfer files from your MacBook to your phone, you’ll need other tools.

:thought_balloon:Final Thoughts

OpenMTP is a practical option for transferring files between Android devices and macOS. Its dual-pane interface and open-source model make it appealing, and many users find it noticeably easier to use than Android File Transfer.

However, the experience can vary depending on the device and file types involved. Some users encounter freezes, connection problems, or compatibility issues that limit reliability.

For many Mac users, OpenMTP works well as a free everyday tool. But if stability or Finder integration is a priority, MacDroid may be a better choice, while NearDrop works well for quick wireless transfers.

Quick setup that tends to give stable OpenMTP transfers:

  1. On the phone
    • Set USB mode to “File Transfer” or “MTP” every time you plug in.
    • Turn off “USB controlled by wireless debugging” type stuff if you use it.
    • Disable any “USB power saving” or “battery saver” while you transfer.

  2. On the Mac
    • Plug straight into the Mac, avoid hubs for first tests.
    • Close Android File Transfer and any other MTP tools so they do not fight over the phone.
    • Keep OpenMTP updated from the latest release, not from an old dmg.

  3. Inside OpenMTP
    • In Preferences, set “Skip errors and continue” for big batches. This avoids one bad file killing the run.
    • Use Copy instead of Move for large jobs. Delete on the source side only after you confirm the copy on the phone.
    • Transfer in smaller chunks. For example 2–3 GB at a time instead of 40 GB in one go. MTP hates huge single sessions.
    • Sort by size and send big video files first, then photos. This makes it easier to see where it fails.

  4. When files do not show up
    • On the phone, disconnect from Mac, open Files or Gallery, then reconnect. Some phones rescan storage only after that.
    • If you wrote to SD card, eject and remount the SD from Android settings when new stuff does not appear.
    • If a folder refuses to refresh in OpenMTP, click up one level and back in, or hit the refresh icon.

  5. When transfers fail a lot
    • Try a different cable that supports data. Short, thick USB C cable from a known brand tends to be more stable.
    • Disconnect, force close OpenMTP, reconnect the phone unlocked, then start OpenMTP again. Do it in that order.
    • Avoid filenames with emojis, slashes, or very long names on the batch that fails. I disagree slightly with @mikeappsreviewer here, I have seen failures even on simple names when the SD card was slow. So also check if you write to a cheap SD card.

  6. Workflow tip that helped me
    • Pull everything from phone to Mac first.
    • Organize on the Mac.
    • Push only the cleaned folders back.
    This keeps weird files on Android from breaking big upload runs.

If you still see random disconnects after all that and you move stuff often, MacDroid is worth testing. It mounts the Android phone in Finder so transfers feel like copying to a normal external drive, and for frequent use it tends to be less frustrating than wrestling with MTP sessions through a UI.

Couple of extra OpenMTP basics that @mikeappsreviewer and @reveurdenuit didn’t really dig into, but that matter a lot for reliability:

  1. Start‑up order (this actually changes how flaky it feels)

    • Quit Android File Transfer and any Samsung / vendor helper apps first. They can silently “grab” the MTP connection.
    • Plug phone directly into Mac (no hub), unlock it, then choose “File transfer” on the phone.
    • Only after that, launch OpenMTP.
      If I do it in any other order, OpenMTP finds my phone maybe 70% of the time instead of 100%.

  2. What to tweak in OpenMTP settings
    Everyone says “just use drag and drop,” but a few prefs help when stuff fails randomly:

    • Turn OFF anything like “auto open on connect” until you know it’s stable. Auto‑opening sometimes races the OS.
    • For large jobs, enable “Skip errors and continue” but also turn ON detailed logging. When a batch fails, you can at least see which file choked.
    • I actually disagree a bit with both of them about filenames being the main culprit. Half my failures were just MTP timeouts on slow storage, not weird characters. Logs made that obvious.

  3. Choosing copy direction & storage

    • Pulling from phone → Mac is usually more reliable than pushing Mac → phone, especially to a cheap SD card.
    • If you must write to SD: do smaller batches and avoid mixing tiny files with giant videos in one go. MTP hates that pattern.
    • If Android has a “use SD as portable storage” setting, make sure it is not doing some encryption or migration in the background while you copy. That kills speed.

  4. Making files actually show up on the phone
    When stuff “copies” but apps on the phone don’t see it:

    • Disconnect cable, open the Files app or Gallery on the phone, wait a few seconds, then reconnect. That often forces a media rescan.
    • If you wrote to SD, toggle “Unmount / Mount” in Android storage settings. Much more effective than just spamming refresh in OpenMTP.
    • Sometimes just renaming the folder on the phone (inside Android’s file manager) kicks the indexer.

  5. When to stop fighting OpenMTP
    If you’ve:

    • Tried 2 known‑good cables
    • Plugged directly into the Mac
    • Switched USB modes a few times
      …and you still get random disconnects on big transfers, you’re probably looking at MTP or device‑specific nonsense, not OpenMTP itself.

    That’s the point where I personally jump to something else instead of wasting a night. A lot of folks above mentioned it already, but this is exactly where MacDroid shines: it mounts your Android storage straight in Finder, so you copy like it’s an external drive and mostly forget about MTP weirdness. It’s not free, but if you’re moving tens of GB regularly, MacDroid is frankly less of a headache than nursing OpenMTP back to health every few days.

TL;DR for a smooth OpenMTP start: get the connect order right, tweak a couple of prefs, avoid monster mixed batches, and don’t be afraid to bail out to something like MacDroid if your specific phone + Mac combo just refuses to behave.

Couple of angles that haven’t really been hit yet:

  1. Think in “sessions,” not “one big sync”
    Instead of treating OpenMTP like a full backup tool, treat each cable plug‑in as a focused session with one goal:

    • Session A: pull all new DCIM/Camera photos to a dated folder on the Mac
    • Session B: push a single music playlist or a single “Movies” folder
      Keeping each session single‑purpose makes it much easier to debug when something breaks. If a “photos only” session fails, you know it is not that random 8 GB movie or your 3,000‑file Documents folder.

  2. Use a predictable folder structure on the phone
    Others mentioned filenames. I think directory layout matters more. Make a small number of “landing zones” on Android:

    • /Pictures/FromMac
    • /Movies/FromMac
    • /Music/FromMac
      Then only write into those from OpenMTP. Apps on Android tend to index these faster and you avoid weird permission issues with app‑owned folders like WhatsApp or random game directories.

  3. Limit parallel operations on the phone
    While OpenMTP runs, avoid:

    • Cloud photo backup running its own scan
    • File managers doing “analyzing storage”
    • Big app updates from Play Store
      MTP is very touchy about concurrent I/O. I see more stalls from background stuff than from filename quirks that @mikeappsreviewer focused on.

  4. Use OpenMTP mostly for bulk, not for “surgery”
    It is fine at moving big batches, less fun for tiny, frequent edits. A nice pattern:

    • Bulk in/out with OpenMTP
    • For single documents or quick photo drops, use wireless like Nearby Share, or a notes / cloud app
      Treating it like rsync over USB is where frustration starts.

  5. When OpenMTP’s UI is the bottleneck
    If you find yourself constantly drilling into folders and waiting for refreshes, that is where MacDroid can be worth it. Since it mounts the phone in Finder, you can:

    • Use Spotlight, Finder search, tags and smart folders
    • Let other Mac apps write directly to the phone storage

    Pros of MacDroid:

    • Feels native on macOS
    • Handles very large folder copies more gracefully in practice
    • Works well with both internal storage and SD, so media libraries are easier to manage

    Cons of MacDroid:

    • Paid, and not cheap if you only transfer once in a while
    • Another layer that can break across macOS updates
    • Still limited by the phone’s hardware and Android quirks, it is not magic

    I would not jump straight to MacDroid, but if you end up doing routine 10+ GB jobs, it removes a lot of fiddling OpenMTP sometimes needs.

  6. A note on what others said

    • I think @reveurdenuit is slightly overcautious about filename characters. They can matter, but in my experience slow SD cards, USB hubs and background Android tasks are bigger villains.
    • @jeff is spot on about connection order, though I have had decent luck letting OpenMTP auto‑open after I unlock the phone first.
    • @mikeappsreviewer is right that OpenMTP is a big step up from Android File Transfer, but I would not expect it to “fix” a flaky phone; if both tools misbehave, assume hardware or vendor ROM issues.

If you put it all together: choose a couple of clean landing folders, run focused sessions, keep the phone as idle as possible during transfers, and reserve MacDroid as the “I do this weekly and I am tired of babysitting MTP” upgrade.
