Yes you mean the window check Fredo6 Plugins for Update?

You mean the dialog window "check Fredo6 Plugins for Update?

I started SketchUp again and It seems to work fine with your plugins.
Thanks for your reply.

@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

@MDVolle
Please explain what's not working, any errors, any Ruby Console errors etc.
What is this 'typo' - tell us [ @fredo6 ] so he can fix it...

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 method register_from_key' for Traductor::ChromiumWdlg:Class> .../body_lib6chromiumwdlg.rbe:1498:in show'
.../body_lib6upgrade.rbe:864:in initialize__' .../lib6upgrade.rbe:161:in initialize'
.../lib6upgrade.rbe:154:in new' .../lib6upgrade.rbe:154:in show'
.../lib6upgrade.rbe:66:in time_for_check?' .../top_libfredo6.rbe:514:in block 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 -dv on 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.

@kashintsev

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.
