About a week ago, I got a new MacBook Pro. I work a decent bit in video editing, among other things, so I had the processor upgraded to the highest available model. The box arrives, I open it, and my word the computer is incredible. Battery life often surpasses 8 hours when running a host of programs simultaneously, everything happens instantaneously, El Capitan is spectacular, the force touch trackpad is incredibly click-like. Basically, the computer is everything I ever expected.
I install a few programs, go about my business, and about a day ago the computer suddenly starts acting weird. I'd definitely call myself a power user, so I'm not sure if it's something most people would notice, but the computer noticeably gets slower, battery life decreases to 4 hours on a charge with few programs running, the computer gets hot, internet misbehaves, and strangely enough, I think Safari acts differently, too. Until I tried Safari on the new computer, I had always been a Chrome person, so I'm not sure, but if I remember correctly a few days ago I could type a URL into the Safari address bar, click enter, and have it load. Now, I type a URL in and hit enter, and the URL gets selected, and I need to hit enter a second time to search. It's subtle, but I think it's a change. Moreover, Mail stops working properly, and now everything I send gets stuck in the outbox, I have this strange window that doesn't seem to belong to any program on screen:
I have clicked the bar and the search button, and nothing seems to happen. The App Store isn't trying to install updates, as far as I can tell, and the window doesn't change the application name in the upper left corner of the screen when I click it. I try opening Safari and get this friendly window:
So I am now typing this question in Chrome. I've downloaded Sophos to see if it can detect any malware, but the scan grinds to a near-halt about 65,000 files from the end of the drive. The hard drive has about 50GB of files in it, and I certainly don't remember putting that much stuff in there in the past week.
Basically, the computer is acting strangely, and I have no idea why. Any ideas?
