    Hi all,

    I have a macbook pro 2012 running yosemite dual booting with the factory hd and a ssd as the startup disk. Today when I woke up the laptop from sleep and plugged it into my monitor (through dvi & dvi to thunderbolt cable) the laptop was stuck on a black screen with the color wheel spinning for over 10 mins, at which point I forced shut down and restarted, thinking there wasnt a problem. But once I restarted I noticed startup was longer than usual, and as it slowly got the to desktop, everything was slow and unresponsive. I'd click on an application to open it or an icon on the top right corner and it would lag, then the color wheel starts spinning for a good 10-15 seconds before it would open the application or the icon. I noticed everything slowed down, including my internet speed, and also transfer speeds between my 2 disks, and from a internal disk to an external flash drive/hd. Restarting and shutting down will also take forever, as I often have to force shutdown.

    I tried all diagnostic tools I could find, incuding running disk utility to repair permissions and repair disk (I did this on normal startup, safe mode startup, and also on the recovery mode), went into single user mode and typed fsck -fy into command to see if that helped, also ran ccleaner to clear temp files/cookies. So far nothing has helped and the laptop is still unresponsive. At this point Im thinking reinstall the os from recovery mode, but in order to do that it has to download the install file which is over 5gb, and my slow internet speed just wouldn't allow that, plus an hour into trying that I get the 1004 error code....

    I'm currently waiting for my friend with a mac to install yosemite and put it on a bootable usb for me to use, but will take a few days. In the meantime is there anything else I can do, or is the only solution to do a clean install?

    Obviously, check Activity Monitor for memory pigs, and do something about them.
    Also check Console for reams of messages like this:
    11/6/14 10:00:00.670 AM com.apple.xpc.launchd[1]: (com.apple.mdworker.bundles[14049]) Could not find uid associated with service: 0: Undefined error: 0 501
    11/6/14 10:00:00.670 AM com.apple.xpc.launchd[1]: (com.apple.mdworker.bundles) Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
    See https://discussions.apple.com/thread/6615545

    or this:
    11/9/14 12:43:40.150 PM CalendarAgent[17795]: [com.apple.calendar.store.log.caldav.queue] [Adding [<CalDAVRefreshDelegateListQueueableOperation: 0x7fa643f808a0; Sequence: 0>] to failed operations.]
    I just disabled the account on this one, and that fixed the endless error parade. You may need to go a different route.

    Generally an internet search on one of the more technical looking sub-bits of a console message eg "com.apple.mdworker.bundles" will get you some useful info on what might work on the problem.
