Hi Folks, I am running Mojave on a late 2012 iMac, 32GB RAM, 34GHz Intel core i7 prcessor, NVIDIA GeForce GTX 680MX (2GB) graphics card, 800GB headroom on the HDD--an old but relatively competent computer. But, its been running slow for a few months now and I can't figure out why. I work daily in Premiere, Photoshop and LightRoom--all software is updated but I am concerned that software updates may be taxing this older model. Although I may run all three programs at th same time--It doesn't seem to make any difference if Premiere is running on its own. I have been working with 20 sequences open in the timeline--but I assume that given the nature of digital this is not using scads of RAM. Any thoughts?
