When did this start?
What version of AE CC 2014 do you have?
You can just paste the log into a post here or upload it somewhere and link that.
Thanks for replying.
Yeah, I've tried copy-pasting the log content into a comment, I've tried uploading the original .crash file, I've tried saving it as a .txt and uploading it. ALL fails.
For a company that invented Creative Suite, this forum tool is probably the worst I've ever experienced.
Thanks anyway Szalam.
The first section of a crash log is often the most pertinent. Try just pasting that.
I'm running CC 2014 on Yosemite on multiple machines with no issues. Make sure you have fully updated After Effects and Yosemite.
The error you've posted mentions a third party plugin. Have you checked with DigiEffects to see that the plugin is certified for use in Yosemite?
Thanks again Szalam - is this enough of it...

Thanks for the heads up Andrew. Yeah, it'd also been working for me up until this point too.
I definitely would have held DigiEffects suspect, except that the first time it crashed was trying to invoke Selective Color, which is a native effect [ albeit, one that has come across from Photoshop ].
Do you have a crash log from a project that doesn't use a third-party plugin?
