  • How do I synch my iPhone5, MacBook Pro and Apple TV so that my iTunes downloads appear automatically on all three devices?

    How do I synch my iPhone5, MacBook Pro and Apple TV so that my iTunes downloads appear automatically on all three devices?

    Let me see if I've gotten this right! You want to remove an account from BOTH machines? Do this for your new machine first, then for the other.
    Click the Apple logo on the top left of the screen, System Preferences, Users and Groups (under Systems), unlock the lock in the window if its locked (you need to know the password), select the user that you wish to remove, and click the - sign next to the + sign for Login options. A window will pop up with some options. Select Delete this user and securely, and click 'Delete user'.
    After this, do an update from the App Store.
    Thats all there is to it.
    For the other machine repeat the process except for one thing. Before you delete the user in this case YOU, you will have to give Administrator priviledges to your son bu checking the box 'Allow user to administer this computer'.
    Do NOT do anything from Finder ... if you dont know how to fix the consequences of the problems caused.
    There is no need to unauthorize your iTunes account on your new machine. Do it on the old machine though.

  • How to erase all datas and reset default

    How to erase all datas and factory reset in iMac

    Boot into the Recovery HD (restart holding down Command+r). Launch Disk Utility and erase the drive (all data will be gone forever so make sure you have a reliable copy of any valuable data). Quit out of Disk Utility when formatting is complete and select re-install OS X (you'll need an Internet connection).

  • How can I share data between WinXP Pro and Mac OS 10.8.3 via wifi

    How can I share data between WinXP Pro and Mac OS 10.8.3 via home wifi.

    Or is there a problem with both OS's writing stuff to the
    ~/Home/Library folder that may be incompatible?
    Yes, big time.  Mail, for sure, has a different file/folder structure, and would not be happy.
    Plus, a number of apps (Apple and 3rd-party) are "Sandboxed."  That's a security feature, to prevent malware or bad coding from affecting things it shouldn't.  Some of their files, including the preferences files, aren't even stored in the same places!
    Or to other places I'm not aware of?
    Probably.  If you have two versions of the same app, they may or may not expect the same data setup.
    To have one User folder for both OS's would save a lot of drive space
    Not if you use some or all of woodmeister50's suggestions. 
    But I'm also not sure how I'd use Time machine with such a set up.
    Just as you do now.  By default, Time Machine backs-up everything (except things like system work files, most caches and logs, trash) for all users and all internal drives & partitions.  By default, it excludes external drives.
    You can change those defaults, of course, via TM Preferences > Options.
    See Time Machine - Frequently Asked Question #32 for details and considerations of multiple drives.
    Presently I backup with . . . clones to other HD's
    Good.   Yes, clones are different.  You need multiple "tasks" to back up multiple drives/partitions.  But once set up, that shouldn't be a big deal.

  • Can I put OS X Yosemite on my 2010 macbook pro with current operating system 10.6.8?

    Can I put OS X Yosemite on my 2010 macbook pro with current operating system OS X10.6.8?  I just bought a new printer and it requires minimum 10.7

    You cannot get Mavericks because it has been replaced by Yosemite. Your machine will work just fine with Yosemite, but you don't have to upgrade if you prefer not to.
    You should always maintain a backup. Hard drives fail, data are lost. A backup is a security blanket for your data.
    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
    1. A Time Machine preferences panel as part of System Preferences;
    2. A Time Machine application located in the Applications folder. It is
         used to manage backups and to restore backups. Time Machine
         requires a backup drive that is at least twice the capacity of the
         drive being backed up.
    3. Time Machine requires a backup drive that is at least double the
         capacity of the drive(s) it backs up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Get Backup
      3. Deja Vu
      4. SuperDuper!
      5. Synk Pro
      6. Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
    Although you can buy a complete external drive system, you can also put one together if you are so inclined.  It's relatively easy and only requires a Phillips head screwdriver (typically.)  You can purchase hard drives separately.  This gives you an opportunity to shop for the best prices on a hard drive of your choice.  Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu.  You can find reviews and benchmarks on many drives at Storage Review.
    Enclosures for FireWire and USB are readily available.  You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports.  I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.)  You can find enclosures at places such as;
      1. Cool Drives
      2. OWC
      3. WiebeTech
      4. Firewire Direct
      5. California Drives
      6. NewEgg
    All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover.  Usually the only tool required is a small or medium Phillips screwdriver.

  • Can a macbook pro run windows operating system?

    can a macbook pro run windows operating system like xp, vista or windows 7?

    Is it best to run Windows 7 in Boot Camp, or would it be better to use VMWare Fusion or similar? I have a MacBook Pro Intel Core 2 Duo (OSX 10.6.8) and I also have a Dell laptop solely because one program that I need to use for work is only available for Windows. I would love to consolidate to my mac but am afraid installing Windows will ruin it!
    It all depends on what your useage of Windows will be, for playing games install it in BootCamp, for word processing, spreadsheets, email. browsing etc a virtual Machne will be fine.

  • How to erase all data on E71x ?

    I just bought an E71x and I really regret. Because :
    1. batter--hard to take it in/out
    2. Sync--no contact group function when sync with outlook. I have to group my contact manually
    3. Voice command sucks
    4. Very hard to hard rese/erase all data after doing the factory configuration
    Can anyone tell me how to erase all the data? My steps are as follows:
    1. Go to factory configuration
    2. Enter lock code 12345
    3. After the device restart, calendar/to-do data... are still on the device.
    Thank you in advance.

     because newer nokia devices have udp- user data preservation feature even if you reset your phone data will remian intact. the only way to truly get rid off your stuff is to use option 3 on this list. understand that you will lose all your data and make sure you ahve a back up of everything you need before doing this. the default code is always 12345. the restore setttings option DOES not remove any data, just restores default settings on your phone. 
    1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
    Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for all operations listed here is 12345
    2. *#7370# - Reformat your phone
    3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
    hard reset - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM - use the following buttons to do a hard reset, GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800's that have firmware version 20... and up. )
    If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.
    You know what I love about you the most, the fact that you are not me ! In love with technology and all that it can offer. Join me in discovery....

  • How to erase all data

    I want to erase all data before I give my iPhone 5 to repair.
    When I go to "Erase all Content and Settings"
    it askes me for my 4 digit Passcode.
    The problem is, I never set a Passcode to the iPhone.
    I did once to my iPad.
    I tried 2 different Passcodes I used on other devices, none of them worked... of course!
    So how can I erase the data on my iPhone then?

    if I will do that, what happens to the backup I wanted to bring back when I want to restore the phone to its current state? It might overwrite an empty backup over the original one?

  • SMC Bug on ALL Haswell-based MacBooks (Pro and Air)

    There is a current SMC bug in all haswell-based macbook pros that prevents temperating reporting apps (iStat Menus, etc.) to be unable to report temperatures when the CPU is in a low-power state (i.e. idling)
    To replicate:
    1. Make sure you are running the latest version of iStat Menus (5 or latest version of 4).
    2. Notice the sensor data, temperatures, voltages etc.
    3. If the notebook is running on AC power (i.e. is plugged into Magsafe) the CPU will automatically idling at a higher step value.
    4. If the notebook is unplugged from AC power (i.e. is unplugged from Magsafe) the CPU will automatically idle at a very low step value (to conserve battery).
    5. When the CPU is in this lowest idling state, several features of the SMC become unavailable too (i.e. the ability to read temperatures, voltages, etc. and write values to control fan speeds).
    So, if unplug the magsafe, with light usage, you will notice your temperatures will "freeze" and report the same temperature indefinitely. Once you plug into AC power, the temperatures, sensors, etc. will begin to update again.
    I am trying to get Apple to fix this. I have tested this on Late 2013 and Early 2014 Macbook Pro's and Air's, they all do this.

    No... You are dead wrong.
    This is a problem with Apple's code. Every piece of software that I have named has been updated to read the new "keys" for the new Macbook Pros. For some reason, when the CPU is in a low power state, the SMC actually powers down and refuses to respond. This is why those API calls are failing, the SMC has nothing to return. However, once the CPU speed steps up again to higher multipliers, the SMC turns back on (presumably to perform thermal management).
    So before you start accusing me of accusing Apple, hear me out.
    Before Haswell-based Macbooks, the SMC did not behave like this... How can this be the fault of the third-party developers?
    I have been in contact with iStat Menu's developers for months now and they too have come to the same conclusion. There is nothing they can do to fix this as the problem lies at a very low level in the SMC.

  • How do i view photos in macbook pro, and while viewing how can i delete the unwanted photos with delete button?

    1 My questions are about viewing and managing photos from a folder.
    a. How do i view photos in macbook pro - i know the space bar thingy but does not help my purpose?
    b. While viewing how can i delete the unwanted photos with delete button?
    c. How can i increase the size of the photos that i am seeing in the form of icons?

    double clicking in iPhoto will open the photo.
    The left and right arrow key will move between photos, as well as swiping on a trackpad or Apple mouse.
    See >System Preference>Trackpad or mouse  for options and tut
    While selected or in the smaller icon view hitting the Delete key will delete the pic.
    Command Z will undo the last action taken.
    Periodically you have to empty the iPhoto trash.  iPhoto drop down menu>empty trash
    Same applies for viewing pics in a Folder NOT in iphoto,  Use the up and down arrows does not work in Preview, but as you know in QuickLook (spacebar) the up and down arrows will navigate.

  • Apple put a new hard drive into my MacBook Pro and updated the system to Maverick. They did not put iPhoto and iWeb on it but I did have it in Lion. Why and what am I supposed to do?

    Apple put a new hard drive into my MacBook Pro and updated it from Lion to Maverick. They did not put iPhoto and iWeb on it but I did have it in Lion. They also didn't put Pages, Keynote or Numbers back on it until I argued with them. Of course, I didn't have my data backed up. My hard drive was destroyed when I tried to install the update of Mavericks myself. I should not have to buy iWeb and iPhoto when I already had them. Suggestions?

    cwhargrave,
    have you tried looking in the App Store, to see if you can redownload iWeb and iPhoto there gratis?
    If you haven’t done so already, you should purchase an external hard drive to act as a Time Machine backup destination, so that you’ll have an option to rollback to a working environment if a new OS installation is troublesome.

  • Macbook pro : error loading operating system

    So my problem is an interesting one. This was setup with bootcamp with xp and oxs 10.4 originally if I recall correctly. So I went to go back into the mac side and it failed to boot. I couldn't find my boot cd for some time so she sat. Then I found a 10.5.1 disk and she'd boot with it but couldn't mount the hard drive for tests or anything. I was able to wipe the drive and then mount it. But doing so wiped my mac partition, and the disk I was loaned wouldn't do the install so I went down to the mac store to buy brand new copy of now leopard... Got home and the drive don't recognize it. There is a dvd drive in this macbook pro, and I can through in an xp cd and it reads it fine but the funny thing is that now it also will no longer read the 10.5.1 disk I used to get to disk utility before. It just kicks it back out. So anyone got any ideas? It will read an xp boot installation cd. But not a brand new snow leopard or even the older 10.5.1 disk it was just reading fine. Thanks again in advance for help.

    You need to locate your System DVDs that originally came w/your computer. You cannot use System DVDs from one mac to another because they are _*machine specific.*_ More than likely, it is probably the reason why the retailed purchased DVD did not work.
    You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
