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?
