So whenever I use certain BCC effects (specifically BCC Led) my after effects crashes and generates an error message. I have provided my laptop info and the error message. I know someone will comment on my memory number, but at one point I was able to use this effect despite the memory number.
Start by checking the BorisFX site for an updated version of the plug-ins. They may have a fix for your situation. That aside, yes, your Mac isn't top of the line and in particular the lack of a dedicated graphics unit may be a problem that cannot be resolved.
