My mba woke up with the flu: fine yesterday, absolutely punky today. Like, the finger scroll move doesn't work, programs don't load (or load in 2-5 minutes), when I type there's a time lag for the letters to appear onscreen. I have run disk utility and applejack, and am also looking at the Activity Monitor. CPU system % is 80; 107 processes, 538 threads. System memory says wired 871.7 mb w/ VM size 228.35 GB, page ins 668.2 but no page outs. Disk activity shows lots of red spikes - peaks over 1 mb/sec. It's a mid 2011, 13", 1.7 GHz Intel Core i5 processor, 4 GB memory, Intel HD Graphics 3000. I currently have Chrome, Word, Preview, a printer app, and the Activity Monitory running (so not much). I've restarted several times this a.m. to no avail, after running applejack, disk utility. If this is NOT the right place for advice, can you point me in the right direction? Thanks!
