Q: Bus error: 10

What is the meaning of: "Bus error: 10"

 

I installed update 10.10.4 and my MacBook Pro 15 inch (early 2011) which has been running Yosemite has nearly impossible to use.

Virtually any mouse click resulted in a couple minutes of the spinning beach ball before responding to requests.

Ran disk utilities and fixed permissions. Ran slightly faster. Still unusable beach ball on each mouse click.

I booted to safe boot mode to attempt to run a backup. It gave me an error message "can't write to drive"

I verified this new 2Tb external drive had no issues. Tried again. Same error.

Them I rebooted to normal boot. Backup hung at approx 50Gb.

Tried to retry safe boot mode, computer hung at point of loading desktop image. Gave it 2 hours to get past this point.

Booted back in normal, attempted time machine again and based on a you-tube video, I went to console, searched for wdworker to search for errors...

in on the system.log I find: (shortened for readability)

...com.apple.xpc.launchd[1] (com.apple.mdworker.32bit.02000000-0000-0000-0000-000000000000 [6813]): Service exited due to signal: Bus error 10

 

note 1: [6813] is incrementing for each entry.

note 2: I tried to give full account of steps. A few iterations left out.

note 3: I can give more detail as necessary.

 

Anyone in Apple Land have a clue?

MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10), batt charge erratic since Yosemite
