Rcloneview crashes on open - macOS Tahoe M5

General
1

Hi,

New to this forum so apologies if this isn’t formatted correctly.

Short story: I can’t open Rcloneview on my new MacBook Air M5. I actually got it to work on my old MBP 2018, but it was so slow and kept crashing. But upon installing on my new laptop, it just won’t open every single time I try to open through the Applications folder.

I’ve done everything that I could find on this support site. I downloaded/installed macFUSE and enabled kernel extensions via Recovery. I downloaded rfuse on its own and installed it. But rcloneview still won’t load.

Anyone know how to fix this? Thanks!

Welcome to the community, @ampmrcloneview.

Since RcloneView is compatible with Apple Silicon, the instant crash on launch is likely related to a specific system conflict or a corrupted configuration rather than the architecture itself. (Also, you don’t need to worry about macFUSE for now, as it only kicks in when a mount is actually triggered, not during the initial app launch).

To help us pinpoint exactly why it’s crashing on your M5 MacBook Air, could you provide a bit more diagnostic information? Here is how you can get it:

Run the app via Terminal

Running the app through the Terminal will force it to output any error logs right before it crashes.

  • Open the Terminal app on your Mac.

  • Paste the following command and press Enter:

/Applications/Rcloneview.app/Contents/MacOS/Rcloneview
  • Copy and paste any error messages or output that appear in the Terminal here.

Check the macOS Crash Report

When the app crashes, does a window pop up saying “Rcloneview quit unexpectedly”?

If so, click on the “Report…” or “Details” button, and look for the following lines near the top:
Exception Type:, Termination Reason:

Please copy and paste those lines (or the first 20–30 lines of that report) in your reply.

With these logs, we should be able to figure out what’s stopping the app from opening. Looking forward to your update!

Thanks for replying! I didn’t get a pop up of “quit unexpectedly” so I don’t have a crash report.

Here’s what I got when I ran the command through the Terminal:

2026-06-22 20:18:24.163 Rcloneview[23050:869738] Running with merged UI and platform thread. Experimental.

Hi — thanks for the detailed report, and sorry for the trouble on the new machine.

Quick note: the lines you pasted (the “merged UI” message and the sqflite warning) are normal
startup output, not the problem. macFUSE only affect the mount feature and won’t stop the app from opening — no need to chase those.

We found a likely cause: on some newer Macs the app can start but its window never becomes visible, so it looks like nothing happens. We’ve built a fix for exactly this. Could you try this new build?

RcloneView 1.4.49 Download Link

Please fully quit any running copy first (right-click the Dock icon → Quit, or Activity Monitor),
then install this version over the old one and launch it.

If it still won’t open, that tells us a lot too — in that case please grab one of these so we can
pinpoint it:

  1. Open the Console app → check Crash Reports and Spin Reports for any Rcloneview entry, and send us the file. (Or in Finder: Go → Go to Folder… → ~/Library/Logs/DiagnosticReports, look for Rcloneview-*.ips.)
  2. Or, while the app is open but stuck, run this in Terminal and send us the resulting file:
    sample RcloneView 5 -file ~/Desktop/rcloneview-sample.txt

Also, your exact macOS version (Apple menu → → About This Mac) would help.

Thanks again!

Update: I downloaded the app through the link. However, it still wasn’t working. And I had tried to check the Console app. No Crash or Spin Reports.

However, I did figure out a workaround! I’m actually new to MacOS and back in the day, I remembered that opening a program “as an administrator” sometimes fixed the problem. I had to look it up, but I was able to use the Terminal and use sudo to open up the exec file inside the Package Contents. That worked perfectly!

I should also say that opening Rcloneview regularly still doesn’t work. So everytime I had to open the program, I’d have to do it through the Terminal. Not sure if that’s info that’s helpful for you for future bugs.

Thanks again!

Thanks so much for the update — and honestly, the sudo workaround is a really helpful clue on its own. :folded_hands:

Here’s what’s going on: the app isn’t actually crashing. It launches and keeps running, but its window never becomes visible — which is why there’s no crash or spin report to find. The good news is that the process is still alive in the background while it’s stuck, so we can capture exactly where it’s getting stuck.

Could you help us grab that? The most useful thing would be to run it without sudo this time, and capture a dump while it’s hung:

  1. Open Terminal and launch the app directly (no sudo):
    /Applications/RcloneView.app/Contents/MacOS/RcloneView
  2. (Adjust the path if RcloneView isn’t in your Applications folder.) Leave that window open — it’s expected to just sit there with no window appearing.
  3. Open a second Terminal window and run:
    sample RcloneView 5 -file ~/Desktop/rcloneview-sample.txt
  4. This creates rcloneview-sample.txt on your Desktop. Please send us that file. (It may ask for your password — that’s fine; it doesn’t change how the app is running.)

That sample will show us precisely which step the app is waiting on, so we can fix the root cause rather than have you rely on sudo every time.

Also, could you confirm your exact macOS version (Apple menu → → About This Mac)? On the newest Macs there are some stricter first-launch permission checks that may be involved here, and knowing the version helps us narrow it down.

Thanks again for sticking with us on this — this will genuinely help us fix it for good.

Apologies for the delay.

I actually tried to run Rcloneview from the Applications folder without sudo and it opened without an issue! I think the problem fixed itself? I’m not exactly sure how.

I did follow the steps you outlined and in the Terminal, I got this message:

2026-07-05 17:28:26.226 RcloneView[23246:739849] Running with merged UI and platform thread. Experimental. flutter: *** sqflite warning *** You are changing sqflite default factory. Be aware of the potential side effects. Any library using sqflite will have this factory as the default for all operations. *** sqflite warning ***

Does this warning help you in any way?

I also have the rcloneview-sample.txt. How can I send it to you? I don’t see an upload function in the message panel.

I also just updated my OS the other day. Here’s the exact macOS version from “About…”: 26.5.2 (25F84)

Let me know how else I can help! Thanks!

Thanks for following up.

You can now drag and drop the rcloneview-sample.txt file directly into the text edit box to upload it. I have updated the site settings to permit .txt file uploads, up to a 10MB size limit.
