Logged in MR-2375. Yes, I think a file would be helpful in this case. Thanks in advance!

@dan: Am sending this client file to you via your upload site. Possibly worth noting is that I was working with PrintDisplay ON during both of the hangs. ~Dave

Got it! Thanks again.

Just happened to me too, trying to change text from normal to bold using the ‘‘T’’ - running the latest WIP

My file also involved Helvetica text, in both regular and bold styles.

Perhaps this venerable font is nervous in Rhino – afraid that it might be extruded or outlined! :wink:

Interesting. Did it hang when you pressed the “T” button; or did the popover menu appear and then hang?

Hrmmmm. I guess it could have been the font getting “nervous” about being used outside of sanctioned Swiss contexts. But seriously…it would be good if you checked your fonts for problems to see if this helps.

Flush left everyone … I happen to use Helvetica too … I cannot even change my font in the text dialogue box.

Tried clicking the select numerous times.

I am assuming this is the Apple supplied font, I haven’t added any other fonts to my machine.

As a side note, I am getting silent crashes when running a python script that uses rs.AddText … check out this thread … Python script crashing Rhino 5.1 & WIP

Could these be related? This past weekend Rhino would go through the script in the thread I mentioned and just crash after i placed my point for text insertion. No crash report or anything, just gone!

Hevetica checks out as valid on my end. Looks like this is an Apple font. The file is enclosed.

However, there may be issues related to other fonts. Worth noting is that Font Book identified 33 fonts in my library as having potential problems (showing up as enabled duplicates) BUT when I search for enabled duplicates, none were found. Weirdness… (1.0 MB)

I presume Font Book was not able to “fix” any fonts though?

Having any fonts “broken” in Font Book could mess up the font caches that all applications use to build the list.

This is correct. Several fonts were indicated as “minor problems…proceed with caution” (33 out of 669… yeah, way too many fonts, I know!). No such warning for Helvetica, as I mentioned above though.

When I go to some of these supposedly duplicate fonts, the ones I checked are turned off.I kind of recall doing this manually a while back when previously trying to diagnose something. Not sure if all 33 are this type of “minor problem”.

That said, I don’t seem to automagically be able to find and delete these in Font Book. Although, if you’d like me to manually do this, I can give it a whirl for future testing (but you will owe me a beer, though). :wink:


@dan: OK, make that a good single-malt…

In the interests of computational hygiene, I decided to delete the offending fonts. While flossing, I found something that might be useful here. Some of these fonts were duplicate items installed from God-Knows-Where, but a good number of them (say half?) were actual System Fonts that required entering my admin password to delete each and every one of them, one at a time (hence upgraded requirement for a finger or two of Glenfiddich or Balvenie :slight_smile: ).

I don’t believe I’ve ever done any weird “under the hood” messing with font installations in the actual system. But, I have done system migrations several times over the decades. I wonder if Apple may have flubbed something somewhere? If this were the case, one might readily see some of these issues with long-term Mac users, more so than more recent Mac users.

Dunno… just a theory.


Hi Dan, I think the popover menu appeared but I can’t get this problem to repeat, either on a new file or the one that was giving me problems yesterday… odd! Helvetica should feel at home, I’m in Switzerland!..

Oh man. I definitely owe you more than just a beer - and not just for this! (though you could have written a bash script for you to sudo rm <youroffendingfontlist> …but what fun would that be?)

I just hope this makes a difference. I’m not sure what is causing the font caches to get out-of-whack. I think it’s a permissions issue, but I’m not sure. I’ve seen them get hosed on my machine before when I had to bail in the middle of an Adobe update. But I’m still speculating that font-caches are even the related tothe problem. At this point, we’re just eliminating variables.

Thanks for keeping an eye on this.

Been there, bailed that. Just love that company! :wink:
