Porthole

An early shift in the mostly abandoned building.

So. This is the thing. I have upgraded to Yosemite on my Mac and now my photo plug-in I use all the time whether in Aperture or LR has been de-activated and it will not let me re-install it.
It also takes my Mac upwards of 5 minutes to start up.
Has anyone else has these issues? If so, how did you fix them or did you just throw your computer across the room?!
