Can I interrupt a migration from Mac Book Pro to Imac and what are the consequences

can I interrupt a migration from Mac Book Pro to iMac and what are the consequences

Les:
Here are some options:
• You could copy the data file to your laptop, work on it, and update the file on the iMac when you are back.
• You can use an application like Log Me In to access your home computer from your laptop.
• You can use DropBox. Install it on both computers, place your data file in a folder on the iMac, access it and work on it on your laptop and it will be automatically updated on your computer at home, even if it is not turned on, as soon as it is connected to the internet.
Please do post back with further questions or comments.

All my Photos disappeared after I saved a photo from an email from my wife. I am running Mountain lion on Mac book pro 2012, help. What did I do wrong?

All my Photos disappeared after I saved a photo to Iphoto from an email from my wife. I am running Mountain lion on Mac book pro 2012, help. What did I do wrong?

Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

My Mac Book Pro is giving me a message that the start up disk is full, how do I delete files, and what files should I be deleting

There are several nice programs that can help you figure out what's on your computer - OmniDiskSweep, WhatSize, and DaisyDisk are the three I like. If you've had your computer for a while - and especially if this isn't your first Mac and you've been migrating from one computer to another, one of these programs can help you find files you didn't know your computer still had. For example, when I was trying to shed files to fit int a 256GB SSD, I discovered I had nearly 1GB of files in my Application Support folder belonging to programs I no longer used.
Other than that, your easy choice are music, video, and photos. They tend to be the big files. A movie will generally be at least 1.25GB, for example.

The touch pad on my Mac book Pro is very sensitive and causes changes without hardly touching it. Can this be changed or does it need replacement?

The touch pad on my Mac book Pro is very sensitive and causes changes without hardly touching it. Can this be changed or does it need replacement?

Touchpads are just that, touchpads.
You touch it and something happens unfortunately, you can't rest your fingers on it while your waiting to do something else or it triggers a response.
You either have to train yourself to remove your fingers and keep them suspended, causing wrist, arm and hand pain, or plug in a standard mouse where nothing happens until you press the button, like years of ergonomic experience has shown is a much superior method.
Touchpads are likely less expensive to produce and breakdown less often under warranty, so just like less expensive to produce glossy screens, it's a cost cutting measure they were incorporated into our devices and required users to adapt to sweeps, gestures and other useless actions for little benefit.
I've owned my Early 2011 MacBook Pro for a year now and have only used the trackpad once, the mushy keyboard perhaps only a couple of dozen times. Preferring external devices where I can rest my digits and nothing happens until I apply pressure or use a scroll wheel.
Needless to say my keyboard area is in brand new condiiton, remains covered from the original packaging, protects against dirt and spills too.
Mac's keyboard and trackpad area tend to wear out pretty fast, like in about 3 years, making one consider getting a new machine long before it physically fails.

I've tried to set up a new user on a mac book pro and i restarted it to create the new account but now all i can get is a white screen with the apple logo and the loading symbol what can i do ?

I bought it from Other World Computer last week for $95. 3rd party, I suppose.

MiniDisplayPort-to-? adapter, available at Apple stores and Best Buy and antplace selling Apple. Plugs into the Thunderbolt or "lightning bolt" port.
Replace ? with HDMI or VGA or DVI.
Know that TVs spave pixels further apart, for viewing at 10-15 ft instead of close as monitors do. Makes viewing small text at 10 ft difficult sometimes.
Another poster also recently reported that using the mouse on the external display is "laggy". Some models of Mac have only a graphics card integrated into the CPU (which can be challenged by running a big external TV) and some have a "discrete" or "second" graphics card that handles TVs better.

Yes. You need 2011 or later in order to mirror as it requires the newer processor. The alternative is airparrot, which does it via software.

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac? Thanks a lot. Carlo Molinari (Rome - Italy)

How can I do to transfer all iTunes library from my Mac book Pro to Time capsule without to lost the alphabetic sequence of songs & artists? What is the correct way to transfer my 3000 songs to Time capsule, to free the memory of my Mac?
The following are the basic steps to transfer your iTunes Media folder from your MacBook Pro to the Time Capsule (TC). Note: You will leave the iTunes Library, and its associated files, on the MacBook Pro as you will only be moving the media files.
Be sure to shutdown iTunes before starting.
Next, move the "iTunes Music" folder, located in ~/Music/iTunes/, to wherever you want on your TC's internal hard drive. Remember to leave the Album Artwork folder, as well as the three individual library files where they are on the MacBook Pro.
Wait a while. If you have a large library, this will take a bit of time.
Once the iTunes Media folder has been transferred, open iTunes. Note: It will still be looking at your local iTunes Library on the MBP. As such it will think that the iTunes Media folder is still on the MBP as well. However, we just relocated it to the TC. If you attempt to select any song, you will get an error that the song is "missing." Not to worry, we will correct this in the next step.
We need to tell iTunes the media has moved to the TC's internal HDD. To change where iTunes "looks" for the media, open iTunes and go to the Advanced > General tab and use the "Change..." button to tell it where your new "iTunes Music" library is located.
Once this is done iTunes will likely pop up a progress window telling you that it's re-analyzing your library. Let it complete this step.
As a final check to make sure everything when as planned, click on any library file from within iTunes and press cmd + i (or View > Get Info). At the bottom of the Summary tab in that window is a "Where:" section that tells you the actual file path to that piece of media; be sure that path begins with the name of your TC's drive, and not "Macintosh HD."

Mac Book Pro (Mid 2010) is no longer recognized the external monitor since Lion update.

Mac Book Pro (Mid 2010) is no longer recognized the external monitor sinceLion update. On Mac OSX 10.6, I had no problems.
Mac screen is just blue, as if he switches. But then there is no further signal.
What can I do?

Bump- I have the same issue. Screen slowly dims for no observable reason until I rearrange to point it more directly at light source. Odd thing is that the light in the room does not change. So scren will be fine for hours while I am working and at some point just slowly dim until I rearrange. Any information helpful.

Mac book pro has grey screen with apple in the middle

my mac book pro has a grey screen, apple in the middle and a spinning wheel. i have tried the command r. nothing is working

Mac OS X- Gray screen appears during startup
Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard Without Erasing The drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing The Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
Restart the router and the broadband device, if they're separate. Any change?
Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
Are any other devices on the network, and if so, are they the same?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
If you're running a MacBook with the lid closed, open the lid. Any difference?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?
