How long should Loading Installation Information take with a formatted Drive?

The OS was corrupted when installed over an incompatible 10.6 version of Centrify.  It should have been uninstalled prior to installing Lion, so I was hoping to do a fresh install without restoring anything related to older applications to sort out network hang conditions.  Restoring from Time Machine does not appear to offer selective restore in terms of Apps and Users. 
I am now waiting for more than hour at a window over the prompt "To set up the installation of Mac OS X 10.7, click Continue" that says:
To download and restore Mac OS X, your computer's eligibility will be verified with Apple. This just has a throbber spinning in front of the message
Loading Installation Information... "  I have about 16mbit/sec Internet connectivity, how long should this phase of the reinstall operation take?
When I first installed Lion, a bootable image of the initial version of Lion was made that was able to restore Lion to an erased drive in about 28 minutes.  It seems that image has been disabled by changes the MacBook boot flash.  Is there a way to be better prepared, and how long should this process take starting with an erased drive?

Sorry to hear that saga. This time download another Lion installer from MAS by going to purchases and holding the option key. When downloaded it will appear in /Applications. Save it off to several different places on your disk and off.
Also, consider keeping bootable clones with SuperDuper or CarbonCopy Cloner.
That way if you have a problem, just boot up from the clone and keep on working until you're ready to fix.

  • HT1176 how long should an initial backup take?

    How long should an initial backup take?

    If the Mac is connected to the Time Capsule using an Ethernet connection, the backup will proceed on average at about 30-35 GB per hour.
    So, if you have 100 GB to backup, the process will be approximately 3 hours.
    Bets are off with a backup using wireless, but it will likely be at least 3-4 times longer than the wired Ethernet connection.

    About how long should an ICloud backup take?

    Well, it went from 8 to 10 to 12 to 18 to 22 hours...then it stopped and said can't restore from icloud. I guess I'll give itunes a shot.

  • How long should the installation of new software for iphone take.  Mine has been downloading now for over 3 hours.  I don't want to disconnect and lose my data.

    How long should it take to update an I 4 phone to the new system.  Mine has been going for 3.5 hours and is not finished, but I don't want to disconnect and lose my data.

    Mine took about an hour or so but it mostly depends on your modem and processor speeds. You can check the progress by clicking your iphone on the left and then checking the download progress. As long as that is moving I would just leave it and wait but don't let your computer shut down.

  • How long should upgrade to Yosemite take?

    I have downloaded Yosemite from the AppStore and on my initial attempt to install got to the point of having a grey screen with apple in the middle and a progress bar which stopped about 1/4th the way to completion.  I let it run overnight after reading posts online indicating that it should resolve itself with time.  After over 12 hours, I restarted the late 2012 MacBook Air and it would immediately go back to the same point in the installation.  I then booted to the recovery disk and restored Maverick from my TimeMachine.  I have tried to install again and have been stuck in the same spot for over 12 hours.  I've tried entering Command-L to observe the log file with no change in what is being displayed.  How long should I wait?

    Install after download seems to take around a half hour.  Of course it will depend on your hardware.

  • How long should my iPad 3 take to charge

    How long should it take my iPad with retina display to charge?  It takes about 15 hours to charge now from being dead.

    FYI
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery
    http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • How long should my nc8430 laptop run with a new 14.4 volt 4400mah battery

    Hi I have replaced my laptop battery with a new 14.4 volt 4400mha . with a full charge and power settings at minimal how long should it run I am getting just under 2hours is this normal with intel centrino my previous battery was getting more than three hours.
    thanks

    I run a 7440 mha battery on an nc4400 and on high performance with no power savings, I get about 2 hours out of it.
    So, I would say for yours, that's about right.
    Maybe your old battery had a higher capacity. 
    Did someone help you? Pay it forward. Help someone else.

  • HT3805 If I have 500,000 images, how long should a library rebuild take?

    I have close to 500k images and had to do a library rebuild. It took over 10 hours, but never stopped.  Now that it has processes all the photos, it is still saying processing and I'm just waiting.  How long should I wait?

    40 hours.
    Seriously.
    It will finish.
    There's not much else you can do.  If you stop the process, you just have to start over.

  • How long should Restore from iCloud take on iPhone 6?

    I have just purchased a new iPhone 6 and after downloading whatsapp, the restore from iCloud function is currently active for 32060 messages and 3421 photos, but has been for the last 12 hours and is now frozen on 91%.
    I am not sure how to access my whatsapp now as I cannot seem to exit the restore from iCloud function but it will not proceed forward with the restore.
    Is there any way for me to resolve this?

    Hello Mark,
    Thanks for using Apple Support Communities.
    From your post I see you're concerned about the time for how long it's taking for your iPhone to restore from iCloud.  There's no set time for completion of an iCloud backup, as the time does vary based on how much content needs to be restored.
    The restore process is taking a long time to finish
    The amount of time needed by the restore process depends on your geographical location and the speed of your Internet connection. Even with a fast Internet connection, the restore process might take 1 to 4 hours per gigabyte to complete.
    If you're traveling between countries, the restore process might take longer than usual. iCloud is tuned to provide the best service when you're in the geographical location from which you most frequently connect to the Internet. When restoring from an iCloud backup, iCloud is tuned to provide the best service in the geographical region you were in when you created the backup.

    Have a great weekend,

  • How long should One hour of DV with TC gen take to export Ref file to deskt

    DV footage in a DV timeline.
    Only TC gen effect- which I believe is real time- (plays down fine without render)
    Export QT ref (no movie self contained) takes 17 minutes??
    Ever since I've gone to SL I have been having drop frame issues, long renders, etc.
    what's up?
    I have 16gigs, ATI 4870, Dual Quad, ect. Machine should be quick (and it was)
    (SL was fresh install)
    maybe back to leopard?

    The TC gen effect is real time to play in real time, or in other words creating an hour's worth of the effect in an hour, but it can't create an hour's worth of it instantaneously when doing a qt ref export. That's what's taking 17 mins.
    As for the SL issues. I don't know, are you on FCP7?

  • How long should a MacBook Pro take to start up?

    I purchased my MacBook Pro 11 mo ago, at the beginning it would take about 30 secs to start up, now it takes almost a minute (the same as my old Dell computer) the only program I have installed is Microsoft office, the mac computers at work take about 30 secs to start up.
    I probably don't have more than 10 word files in "my documents" and no more than 500 photos, which I think is nothing compared to ALL the information I have in the computer at work
    is it normal to take 1 minute to start up? What should I do in order to make the start up faster?
    It annoys me that it takes almost the same as my old Dell computer
    Thanks

    Mountain Lion has a annoying feature it loads the last used programs when you log in.
    So disable that, there are various hacks on this thread
    https://discussions.apple.com/thread/3244852?start=30&tstart=0
    See if that improves your boot time and if not, then do the #12/#13 OnyC cache cleaning routine here and reboot when finished.
    ..Step by Step to fix your Mac
    If that doesn't solve it, investigate your Office verison is compatible with your OS X version
    http://roaringapps.com/apps:table
    Uninstall it and see if the boot time resumes normally, or update it or run further through the Steps.
    Why is my computer slow?
    The Mac's at work, are they running 10.7 or later? Or the fast and speedy 10.6
