OSX system health reports

[digitalfailure]

Is there anyway that I can find out the system health status of my 2012 iMac?

Every so often when I plug my iPhone (it's done it on 4s and 5s ...both different cables) into my apple wired KeyBoard I get several pop up messages telling me that too much power is being drawn and that USB is being shut down, As I say it's totally random and I can't reproduce it on demand. Further to that The keyboard has actually stopped working completely a couple of times.

It did it today and the keyboard wouldn't start working again until the machine had been restarted 3 times ! I'd tried changing the USB cable to other ports between restarts, but it was actually back in the original port when it started working again, so this rules out the phones,cables or keyboard as being an issue in my mind which only leaves an internal issue within the USB side of the logic board

Luckily I took out apple care when I bought it

So......do they keep error logs anywhere?

You can do a health check when booting up - hold down option + D. This should check the status of your memory, logic board, and other system failure points. It's an automated process that will go through and check the various system components on your Mac to ensure they are operating properly and give you an update when complete.

Cool, so that's option and d at the same time as booting up ?

I've a feeling the USB section of the board is iffy being as it's played up with 2 different phones and cables and all the ports on the back.

My Macbook has dubious USB ports (very fussy about cables) and posts that message sometimes as well as freezing the mouse if I plug in a USB memory stick - it's been more noticeable since I installed 10.8.

TBH I think USB is just poorly implemented in OSX compared with windows or Linux, and much more temperamental. Hope your machine sorts itself out OK.

I'm only using the apple cables and have tried 2x 30pin and 2x lightning cables over past months.

It's got 2 years AppleCare left and everything is backed up so I'm not too worried

Hi

Yes on boot up press both buttons together after pressing the power button

If this doesn't show anything, I'd still book it in at a Genius Bar as something clearly isn't right.
