I can't get speckle.blender.installer-2026.9.0.zip installed/activated (on Mac Arm ?)

While I had no problems with previous versions until :
speckle.blender.installer-2026.8.0.zip

(Blender latest 5.2.1 LTS official and Blender 5.3 Alpha)

Hi zoomer,

Worth flagging - once again - that 5.2 and 5.3 alpha aren’t in our supported matrix, we currently test against 4.2–5.1 ( How to use Speckle for Blender - Speckle Docs ). Not being able to install or activate the add-on there isn’t something we can meaningfully investigate.

For context: 2026.9.0 did add a new dependency, pyarrow, for the data bundle publish/receive path that 2026.8.0 didn’t have, installed via pip when the add-on registers. If that’s failing on an unsupported alpha build, that’s between you and pip’s wheel matching, not a connector bug we can chase.

If you hit this on a supported Blender version (4.2-5.1), let us know and we’ll take a proper look.

For future reports along these lines - we know you like living on the bleeding edge - it’d help to include more than “isn’t working”. Next time, send us:

  • The actual error text, not just the symptom
  • Blender’s system console output (launch from Terminal to see it)
  • Your exact macOS build number
  • The exact Blender build or commit you’re on
  • Whether that build is a public alpha, a nightly, or something you compiled yourself at 2am
  • Your Blender Python version, in case that’s also pre-release overidden
  • Any hardware Apple hasn’t officially announced yet that you’re somehow already running this on,
  • The lunar phase at time of testing, for completeness :waxing_crescent_moon: :first_quarter_moon: :full_moon_face:

It was only a short Info that something happened since 2026.9.0

Ah, I just didn’t expect that Blender 5.2 LTS (from July) was not on the official allowed install list. So it will not update the hidden Speckle Connector’s Installation Folder.

Can’t find any Blender 5.1 Download to test. I still have a 5.1 Settings folder but I see no traces of 2026.9.0 as it will likely also not update Speckle Installations Folder (to copy over to 5.2+) as long as I don’t run the legacy Add-On installation-from-zip from a Blender 5.1 installation.

Yes, of course, my Specs are as always out of range (e.g. macOS 27 Public Beta) and not helpful (as well as the error : No module named ‘specklepy.api.enums’).

But 2026.8.0 seems to still work fine.
(Besides that my test uploads were already expired again,
an upload test threw a warning :

"Failed to publish: 1 validation error for DataResponse[DataResponse[DataResponse[DataResponse[DataResponse[str]]]]]
data.data.data.data.data
  Field required [type=missing, input_value={}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.12/v/missing
")

but upload worked though …)

And great to see, Speckle got an update available message with a direct download option.
(OK, on Mac it downloaded the Windows exe installer)

So I’ll skip current Speckle versions and wait until 5.2 is supported.
