Delete UserObject does not work on MacOS


I noticed a small bug using custom UserObjects. When I try and delete them from within Grasshopper, nothing seems to happen. The only way to remove them is to go to the actual UserObjects folder and manually delete them.

I can make a new UserObject just fine, and add it to a new toolbar just fine

but then if I right-click and select ‘delete’, (note, the text note in the popup is clipped as well?)

which does not do anything to the file in the UserObjects folder.

If I go in and manually delete it, it does all work that way though, and the toolbar updates as expected.

all the best,

Thanks for reporting, I’ll try and replicate this and file a bug report. I think just the message needs to be fixed.

Hello @Japhy, all

I just wanted to note that this bug still hasn’t been resolved yet and I am still getting the same behavior (not deleting).

Embarrassingly I have no recollection of this (almost a year ago). I dig into this and get back to you my findings. Thanks

thanks @Japhy - no worries. If there is an easy fix it would be great though!
best, @ed.p.may
