Hi Eric, thanks for the suggestion-- here is the output of Etrecheck. I was reluctant to post this after having to agree to their several warnings and disclaimer absolving them of any responsibility, but it looks like fairly generic information. My system currently has much more RAM available now than it does when I typically use it, since it froze completely last night and I had to reboot it using the on/off button (Etrecheck reports this crash in their Diagnostics section).
EtreCheck version: 2.9.9 (260)
