Product: Bambu Studio for MacOS Version: v01.09.07.52 Operating System: macOS 14.5 (23F79)
Summary:
The Filament Settings window in Bambu Studio does not close when attempting to use the red close button in the top-left corner of the window, causing the app to become unresponsive and requiring a force quit.
Steps to Reproduce:
Open Bambu Studio.
Click on the Filament Gear Icon.
Select “Custom Filaments.”
Click on the edit icon of a filament.
Click “Edit Preset.”
Try closing the window by clicking the red close button in the top-left corner of the UI.
Expected Result:
The Filament Settings window should close when the red close button is clicked.
Actual Result:
The Filament Settings window remains open, and the close action is not executed. The app becomes unresponsive, and the only way to close Bambu Studio is by force quitting it.
Workaround:
To close the application, the user is required to force quit by:
Pressing Command + Option + Escape and selecting Bambu Studio from the “Force Quit Applications” window.
Alternatively, using the Activity Monitor to force quit the app.
Additional Notes:
This issue seems isolated to the Filament Settings window.
No error message or feedback is provided when attempting to close the window.
A force quit is consistently required after reproducing this bug.
I have the same issue and I have a feeling one of the force quits also caused one of my custom settings to be corrupt – not showing up on machine but showing up locally on Mac.
Same problem.
macOS 13.6.9 (22G830)
and after I force quit Bambu Studio again…
Version 1.10.1.50
I can evidently set things (they appear after force-quitting and reopening Studio), I just can’t close the window or ignore it and get back to work. All of the drop down menus are greyed out as well.
I have tons of crashes and freezes. I have it with the Filament Grouping popup window when you accidentally hover over part of the top bar… incessant, insane, for people who aren’t super precise with mousse movements… that thing will eventually cause a crash. I think I’ve only had the filament popup crash once or twice.
The other big one for me however is searching for a setting in process panel… that popup often gets stuck and I cannot do anything else and must force quit.
Luckily some of these still allow for saving with the standard keystroke!!! But, yeah, force quitting only way to go about it.
December 2025 checking in to say still experiencing this 14 months after the initial report in this ticket.
MacOS Tahoe 26.1
Bambu Studio version 2.4.0.70
Unbelievable. This bug renders the app nearly unusable on macOS – is there no fix in sight or even some workaround? For starters, can’t I just disable that dialog and select my filament mode once?!
So, after the holiday printing gifts rush, I plan to move to Orca Slicer. I have submitted over 50 bugs to bambu directly with tickets. All they say is “we cannot reproduce this”, after I send them all my files, projects, print logs, screenshots, videos, etc. etc…
Guess what… they ARE NOT TESTING ON MAC!!! This is NOT TRUE CROSSPLATFORM software. They showed me their testing screenshots when I asked… fool them… firstly, it was a different printer than the one I’m using (a1 instead of h2d), it wasn’t even on the computer for one of their shots, it was the handy app… I kept asking, tell me your platform… because they kept asking what mine was, even though it was in the original opening ticket description. Now, after basically telling them how ridiculous they are if they demand all this ■■■■ they just throw out anyway, platform, settings, printer model… etc… that I think I’ll let the community know… they said, “okay, we’ll send it to the correct department…” what is that? Like 3 guys who have two Macs between them, just verifying the app doesn’t crash on launch? I have read the GitHub as well, seems useless. I have a couple of the bugs there that are over 18 months old for Mac… bottomline, BambuStudio for Mac is “BETA” software. PERIOD. Now that Orca works with H2D without more advanced setup, I’ll be switching next month, and hopefully will never have to look back…
Even if we except the myriad crashes I have (mostly from the filament grouping dialog popping up and locking the UI forcing Force quit), there are basically fundamental UI usability issues outstanding that simply ignore basic Mac keys. For example, all the highlighted green buttons on popups that should be accepted by hitting return ignore that… so, basically, the fastest tool on the computer, the keyboard, CANNOT be used 99% of the time in slicing. This is a kick in the nards. Period.
Rant done. Just popped back into the forum after months gone, and see there is still too many protectors of Bambu’s feelings trolling the forums, and bambu still doesn’t care about macOS… bye again! I wanted to help point you toward orca as a possible option for you, caveat, I haven’t actually printed with it, I have played with it in projects however, like I’ve done with Prusa Slicer, then sent the project back to BambuStudio, and give some thumbs to some actually helpful people for a second in various threads.
Anyway, welcome to the forum, we need more like you! Personally I see reddit as WAY less hostile to people daring to criticize bambu…
Yeah it’s a nightmare. I’m honestly trying to fix that issue myself, see how I do. Just getting it to build is a nightmare. But looking at the codebase I suspect this issue might be an easy fix.
I’ve put up a PR (pull request) for at least one major issue (the mouse input issue that renders the app non-responsive). Hope it’s approved and that it ships with an upcoming update…
By the way, assuming that major issue is fixed (the issue you mentioned “the filament grouping dialog popping up and locking the UI forcing Force quit”), what other major issues do you see on macOS? I can try and fix them if they’re easy fixes…
so many, where to start… DM me if you wanna email / discord / phone etc. … sounds like you’d like to focus on UI stuff… if you’re not comfortable or think it’s best to keep it on this forum… mb we should start a new thread focused on you fixing UI bugs for macOS stable branch. I’d be happy to support / test / submit / etc.
