[Plugin Library] LibFredo6 - v16.2b - 22 Sep 26
-
@Rienk My plugins also stopped working correctly with the latest tools update - curviloft is not generating mesh and it appears that edge picker has a typo in it but I can't edit the code

Hi @fredo6 and all,
After two hours of trying to fix the Fredo update-check crash (spoiler — fixed it), here's what I found. Might be useful for pep75/Rienk/MDVolle above too, since it looks like the same class of issue.
Setup: macOS 26.6, tested side-by-side across three SketchUp installs on the same Mac — SketchUp 2025, SketchUp 2026 and SketchUp 2027, each with its own LibFredo6 16.1a (+ FredoTools + JointPushPull) installed via Sketchucation Tools.
Symptom (SketchUp 2025 and SketchUp 2026 — identical on both): the "Check Fredo6 Plugins for Update" dialog opens completely blank (no version table, no icon, nothing), and the Ruby Console shows:
!LibFredo6: Error when requiring Binary .../Fredo6_!LibFredo6/Binaries/Mac_32/bin_body_Lib6G6.bundle - dlopen(...) tried: '.../bin_body_Lib6G6.bundle' (code signature invalid in <...> '.../bin_body_Lib6G6.bundle' (errno=1) sliceOffset=0x00054000, codeBlobOffset=0x000500B0, codeBlobSize=0x00004CE0), ... - .../bin_body_Lib6G6.bundle
#<NoMethodError: undefined methodregister_from_key' for Traductor::ChromiumWdlg:Class> .../body_lib6chromiumwdlg.rbe:1498:inshow'
.../body_lib6upgrade.rbe:864:ininitialize__' .../lib6upgrade.rbe:161:ininitialize'
.../lib6upgrade.rbe:154:innew' .../lib6upgrade.rbe:154:inshow'
.../lib6upgrade.rbe:66:intime_for_check?' .../top_libfredo6.rbe:514:inblock in after_startup'So the update dialog can't fully init because the ChromiumWdlg engine's native module (bin_body_Lib6G6.bundle) fails to dlopen — macOS rejects its code signature at runtime.
Important: SketchUp 2027, with the literal same LibFredo6 16.1a files, has no problem at all — dialog renders fine, no console errors. So this doesn't look like a corrupted download or a bad LibFredo6 build; it looks like SketchUp 2025/2026 vs. 2027 differ in how they enforce code-signing/library validation for third-party native bundles at dlopen time.
What did NOT fix it (ruling out a leftover-config issue on my end):
- Fully quit SketchUp.
- Removed every Fredo6 folder + .rb loader from Plugins (LibFredo6, FredoTools, JointPushPull).
- Deleted every orphaned Fredo6 key from the SketchUp prefs plist (ALToolPalette_Fredo6_, Fredo6_CheckForUpdateWarning.) — leftovers from older Fredo tools removed previously.
- Reinstalled LibFredo6 16.1a completely fresh via Sketchucation Tools.
Exact same blank dialog / same console error on the totally clean install.
What DID fix it (local workaround): re-signing every .bundle under Fredo6_!LibFredo6/Binaries with a local ad-hoc signature:
find ".../Fredo6_!LibFredo6/Binaries" -name "*.bundle" -exec codesign --force --deep --sign - {} ;
After this, the dialog renders completely and the console is clean.
codesign -dvon the original file actually reported the signature as valid (TeamIdentifier 66M89AU23J, properly signed 31 Aug 2026) — it's specifically the runtime dlopen/library-validation check inside SketchUp 2025/2026 that rejects it, not a malformed file.This is obviously just a workaround I have to redo after every LibFredo6 update/reinstall, not a real fix — posting in case it helps track down why 2025/2026 reject it while 2027 doesn't.
-
Thanks for the description.
For whatever reason, the .bundle binary files fail to load for a question of signing and this only concerns SU2026. Note that in SU2027, the .bundle has the same name but is different, as it is for Ruby 3.4, versus Ruby 3.2 for SU2026).
Could you try with LibFredo6 v16.1g, just published and advise if this gets better.

Help,
none of the plugins I purchased licenses for are working anymore !!!
Last LibFredo6 installed : LibFredo6 - v16.2b -
Do you have the latest SketchUcation toolset installed, it manages the licenses.
Which extensions are the problem ?
What happens when you try to run them ?
What error messages or dialogs /
Is the extension's licensing report OK ? -
SketchUcationTools V5.0.8 installed
Fredo6_Curviloft, Fredo6_JointPushPull, Fredo6_RoundCorner, Fredo6_FredoTools : nothing appends when I choice one of this tools.
The extension's licensing report is OK -
All was OK before the last Fredo6_!LibFredo6 update !!!
-
When I run "Check for Updates" for LibFredo6-Configuration, nothing happens.
-
SketchUcation toolset installed : 5.0.8
Extensions : Fredo6_Curviloft, Fredo6_FredoTools, Fredo6_JointPushPull, Fredo6_RoundCorner
When I run, nothing happens (no dialogs errors).
All license are OKWhen I run the Ruby Console and execute the Corner plugin, for example, this is what I get :

Hi, I have a problem. I would like to add Fredoscale plugin, which works with LibFredo6 15.9 or higher. My latest LibFredo6 is 15.8 and all your plugins works perfectly. After installation the newest 16.2 version, no one plugins works. I see icons, they have a color, but do not works. What should I do to fix it? Thank you very much.

@epetit91
You are on a MAC ?
Does the error msg's folder exist:
/var/folders/wr/cl77xmh96bbdjh00dl5shws00000gn/T/com.sketchup.SketchUp.2017.eric/Fredo6_LibFredo6_TemporaryFiles
If so what are its contents ? -
No, I have standard Windows 7 Ultimate. All Fredo plugins works well with LibFredo 15.8. But Fredo Scale works only with LibFredo 15.9 or higher. So I downloaded the newest LibFredo 16.2 and everything stop to work. I see icons, but they are inactive. One picture is with installed libFredo 15.8 and function plugins, another one is with LiFredo 16.2 I can see also FredoScale icons, but no plugin is working

@bublifuk21
That OS question wasn't directed to you.
But your super-old Windows version installation is likely to cause issues - I'm surprised it's worked well up to now...
@fredo6 will undoubtedly have some to add... -
When you have issues with the installation of LibFredo6, can you report the utput of the command menu: Window > LibFredo6 Settings > Fredo6 Plugin Information for Sketchucation Support
This just tells what is your configuration in terms of version installed, Sketchup version, platform, etc...
Otherwise, it is very difficult to help.

Yes, I am on Mac (MacOS 10.12.6)
I have been using Fredo plugins since 2022 and have never encountered a single problem. This issue only appeared after the latest update to FredoLib.
