Hello, this is my first post.
I installed Houdini 16.5.322 QT4 and i'm unable to run the apprentice application at all.
I get a fatal error on startup every time.

My system specs:

MAC Pro mid 2010

CPU:
intel Xeon 2x6 core 2.66 GHZ

RAM:
24GB 1333 MHZ DDR3

Graphic card:
ATI Radeon HD 5770 1024 MB

Attached is the crash log.
I will appreciate any suggestion, please.

Thank you,
Dario

The ATI Radeon HD 5770 is a really old graphics card (and 1GB VRAM is not enough to run Houdini). We recommend a graphics card with at least 2GB VRAM. See https://www.sidefx.com/Support/system-requirements/ [www.sidefx.com] for full requirements.

Having same problem. Mac OS10.10.5 NVIDIA Quadro 4000 2048 MB

Previous version ran fine. 16.5.323 ran for a while, now crashes on start. Uninstalled all Houdini versions, rebooted, reinstalled. Now always crashes (Fatal Error) on start after windows come up. Saves empty scene file on crash.

Checked for library named above and it does exist on system.

If latest version will not work, can we downgrade a version to one that does with Apprentice (please?)

This error is related to Houdini anonymous stats.

The workaround is to disable anonymous stats like so:
- open a terminal and navigate to ~/Library/Preferences/houdini/16.5- Open hcommon.pref in a text editor. If the file does not exist, then create it first.
- In the text editor, look for `sendAnonymousStats` and set it to 0. Or if `sendAnonymousStats` cannot be found, then add a new line:
sendAnonymousStats := 0
- Restart Houdini

Cheers,
Rob

The ‘_clock_gettime’ startup crash is fixed as of tomorrow's Houdini 16.5.351 build. You will need to wait until tomorrow to get access to this build from the daily builds download page.

This fixed it! Thanks Rob.
