10.10.3 won't downlad to my MacBook Pro (13-inch, Early 2011)

I've tried 7 times and each time get a failed certificate error dialogue box and am redirected to download it again. (Also Numbers downloaded, but keeps telling me I need to download it. As does other software updates. This has also happened with an HP Printer update I don't need).
Associated with this (maybe) is that since using Lion with no problems at all, now with 10.10.2 the Task Bar flashes on but is mostly off, and too fast to read when it flashed on. Shame I really like the feature.
I'm not too swift of brain with these types of errors, and usually drown in excessive Apple Support pages! Any simple common-sense answers would be gratefully received!

    Holy crap, I got it to work.
    Essentially, I just waited until DiskWarrior reached Step 9 and told it to skip the step before it had a chance to freeze. It skipped successfully, moved on, rebuilt and replaced the faulty directory files.
    So far the computer is booting like normal, I can log in, and I'm currently copying all of the data to an external as I type this.
    I still have no idea why the computer wouldn't mount or boot to any drive, but I guess I'll deal with that later.

  • My iPhone 5 won't connect to my macbook pro retina over bluetooth?

    My iPhone 5 won't connect to my macbook pro retina over bluetooth?

    Ah, sure it actually won't.  I have the same problem, and I contacted Apple Support.  They told me that there is an incompatability between the iphone 5 and MacBook Pro Retina such that Bluetooth pairing is not possible.
    The Support Agent actually had the audacity to tell me this was part of the design of the OS on the MacBook Pro, like Windows people saying, "That's not a bug.  It's a feature!!"
    Personally, I think this is insane.  While I was trying to tether the iphone to the MacBook Pro retina for an internet connection, there are other reasons related to file transfers for which one would want to pair the iphone 5 with the MacBook Pro retina.
    I am hoping this "feature" is fixed in iOS 7, and/or in some dot release of Mac OS 10.8.
    By the way, the personal hotspot feature on my Verizon iphone 5 works great either via a wifi or USB connection.  There are occaisions, however, when one would 1) not have a USB cable, and/or 2) have another wifi relationship between the phone and a network that one would not want to have to "forget" in order for it not to connect to that wifi network.  The Macbook will not find the iphone as a wifi hotspot if the iphone is connected to wifi in the first place.  At least mine won't.

  • Hi! I got movies on my external hard drive that are AVI kind and won't play on my macbook pro? need some help please!!

    Hi! I got Movies on my external hard drive that are AVI kind and won't play on my macbook pro? When I start playing the movie a message pops up and says "a required codec is not available". I tried flip4mac, xvid, divx already and still not playing my video. need some help please!! thanks.

    Although vlc mentioned above is a much more powerful and better player you could try installing Perian if you insist on using the quicktime player.  It may supply the codec it needs.
    Not sure why you wouldn't be able to play straight avi files though in quicktime.

  • My A'Extreme sometimes won't connect to my MacBook Pro even if I have a green light on the device . I can unplug the ethernet cable and reconnect and it will work fine. all diagnostics say there is nothing wrong. Any ideas ?

    This is more about your modem then anything. Sometimes you'll need to unplug and plug back in your modem. Consider it a glitch from the ISP or just the modem in general.
    when I need to turn something off then on I try the modem first. This when I'm not doing any ware and tare to the device.

  • CanoScan 9000F scanner won't work on my MacBook Pro even though it should be compatible with the Mac 10.7.2 OS.

    My new CanoScan 900F scanner won't work on my MacBook Pro even though I've followed all instructions to make it compatible with the 10.7.2 OS. The USB connection isn't recognised. What else con I do?

    I have a similar problem with a new CanoScan 9000F which I tried to use without any success on my desktop computer (Mac Pro 5,1) and laptop (Macbook Pro 1,2) both running OS 10.6. Problem is identical on both, viz:
        •    Scanning process appears to start, a message comes on the screen: Scanning do not open document cover followed by Scanning...
        •    This is then replaced by the message: Cannot communicate with scanner. Cable may be disconnected or scanner may be turned off. Check status. Scanner driver will be closed. 2.155.33
    I've spent several hours on the phone with Canon support but having uninstalled/installed/reinstalled/updated/turned on/turned off/unplugged/plugged/restarted innumerable times, the problem is exactly the same. The scanner icon shows up in the Printer & Fax System Prefs (though without the little status lights) and shows as being connected in the USB tree. I think it's a problem with the scanner, Canon bods are suggesting the Macs are at fault and suggest I try connecting to a wintel (hawk, spit) and it's 100km to the nearest Canon service centre.
    Any suggestions as to what might be the problem/s and what I might be able to do to fix it/them?
    Thanks.
    By the way, bought the Canon to replace a HP Scanjet 8300 which I've used for 6 years almost without problems. Any that I have had have been fixed merely by turning the scanner off then on after a 10 second rest.

    What won't open? Photoshop, or the photos that you "stored in iPhoto"?

    The Software Update pane of System Preferences won't show full version upgrades. If your Mac is compatible with Yosemite, you can either download it from the Mac App Store or order a download code for Mountain Lion from the online Apple Store.

  • I just installed Lion 3 days ago, now my audio won't work, unless I use headphones, also space bar glitches, and other software issues..MacBook Pro 15 inch, and most everything is messed,,but the audio is killing me.

    I installed Lion a few days ago, ever since then my audio won't work, unless I use my headphones.  Also, the saver screen with password changes frequently, and the space bar works when it wants to.  There are many other issues I am having.  My IPhoto,,does not work properly, pages is not working, I have all versions.  The Office Suite is acting strange, and my email accounts work when they want,,,my IPhone 4 won't sync anymore.  The list is endless...does anyone else have this problem?

    Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

  • ICal won't sync from my MacBook Pro to MobileMe

    iCal won't sync from my MacBook Pro to MobileMe.  But MobileMe entries appear on iCal on the MacBook. My iPhone and iPad work fine.  Any suggestions?

    Hi melindybek ,
    You are awesome and already a step ahead! The logs are blank, because by default they are off. If its necessary to turn them on the directions on, instructions of how to to this are at the end.
    To check if they are both on the updated version, its possible to check by going to accounts.firefox.com to see if you are logged in. If so, both are updated. If not, how to update: sign in at that address to be on the new one.
    Toggling the sync may jumpstart it too. Removing the account and adding it back starts a fresh sync, or Tools > Sync Now.
    * How do I turn on sync logs:
    # Open about:config and turn on: services.sync.log.appender.file.logOnSuccess and services.sync.log.logger.engine.bookmarks
    # Restart Firefox and look at: about:sync-log
    # Logs and error messages will be located here
    Please also use pastebin.mozilla.org for sharring any errors that relate to this issue.
    Thank you.
