I now have a new mainboard and a SATA controller card (PCI-E 1x) coming, with two new 2TB drives. Also a cheap small SSD on the way for the OS.
What I want to do: Migrate all data to a new RAID5 array consisting of 4x 2TB drives.
Is this possible without losing any data?
Thanks!

Shameless self-reply-bump;
I now have the new parts except the controller. When I get that I'm going to set up the new system, trying to migrate away all data off one 2TB drive so I can pull it out of the lvm volume group.
Then I can create a new RAID5 array with 2 new and 1 old 2TB drives and start moving the data to that one. When that's done, I'll move the other 2TB drive that was in the volume group, to the RAID5 array. That way I should end up with 4 2TB HDDs in RAID5.
I need to do some research first on what stripe size to use, filesystem, etc, as well as if it's best to have the HDDs on the controller (PCI-E 1x) or on the onboard SATA controller (which should be faster since it's not bottlenecked by the PCI-E 1x bus).
Thanks
Edit: New system installed, data migration ongoing. Managed to borrow a 2TB drive off a friend, migrated data to that so I could take one old 2TB out of the lvm, thus giving me 3 unused 2TB HDDs, on which I created a RAID5 array. Currently migrating data to it while it's initializing the parity etc...

sata_mv: Highpoint RocketRAID BIOS CORRUPTS DATA on all attached drives, regardless of if/how they are configured. BEWARE!
sata_mv: For data safety, do not use sectors 8-9 on "Legacy" drives, and avoid the final two gigabytes on all RocketRAID BIOS initialized drives.
That was the culprit! I shrunk the device usage per partition like so:
Avail Dev Size : 3907025072 (1863.01 GiB 2000.40 GB)
Array Size : 11702108160 (5580.00 GiB 5991.48 GB)
Used Dev Size : 3900702720 (1860.00 GiB 1997.16 GB)
So it's using 1860 out of 1863 or so GB per partition, that way I should be safe corruption wise. It would be best to shrink the actual partitions (sd[b,c,d,g]1), but I don't know how to do that without messing everything up.

How do I migrate data to a new Mac?

A) what is the correct sequence to migrate all my data to a new Mac?
B) does the migration create an exact duplicate of what is in my "home" folder? Including paths to external hard drives that have movies, photos, etc on them? Such as an external iTunes library?
C) what cables do I need for the data transfer? USB? Ethernet?
Thanks

There are many methods to transfer to a new Mac. OS X can migrate just about anything into the new or current operating system. (A)
* If you have an External Hard Drive (Time Machine setup) and backed up everything, OS X can restore the current files onto the new Mac. All it requires is your current credentials stored on the system. (B)
* If you are migrating without an External Hard Drive and you are using a USB Cable, it will detect your computer and perform the transfer automatically after plugged in and following the tutorials (C)
(If you are using Windows and copying the files, you can use a USB transfer cable or copy/paste to the EHD. It's not recommended to use Windows Backup as it will be encrypted)
If you have purchased iPhoto or Aperture, you can tell it to scan your computer and EHD for the photos and videos already stored and it will copy them onto their own location folder after following simple settings.
On a restore, iTunes will import your library of music, videos, and applications and have it ready to sync with your device.
You can also perform a restore of your music, videos and applications (but not photos sadly) via iPhone or iPod or iPad after following two steps:
* Store / Authorize Account (with device plugged in)
* Right click iPhone / Transfer purchases from iPhone
* Device will quote then sync automatically

Migrating data from macbook to MBP questions

i just got a new macbook pro 2.5ghz yesterday. i have been using a macbook late 2008 aluminum. i want to migrate about 225 GB of data from old computer to new computer. What is the fastest way of the available options? I know that wireless is out of the question. i have an ethernet cable and was thinking of using that to connect the two computers. Would it be faster to go from the the MacBook USB to the MBP firewire? Would i use a USB to firewire cable, or a firewire cable with a USB adapter? Any rough idea of how long any of these connections might take for that amount of data? The new computer has a 1 terrabyte hard drive 5400rpm. thanks

The link explains how to migrate data using Mavericks. The Macbook Pro i got is not the retina display model, it's the previous model, which i chose to get so i could get the large hard drive, needing the space. The new MBP came with Mountain Lion, doesn't have Mavericks on it yet. It has a firewire port and a thunderbolt port and two USB ports. The old computer, the MacBook, has only USB ports, no firewire. I'm moving the data from the old computer to the new computer. Since the data is going to the new Mac, i thought would be the Target Disk, right? So, i will put the old Mac "in Target Disk," is that right? That means it's going to target another disk, is that right? It's confusing temrinology, but i bet it's perfectly clear when you are doing it and following the process.
So firewire is the fastest choice and in order to use it with these two computers, i need to use a USB to Firewire cable to connect the old computer to the new computer, if i understand right.
Do you know if there's any source of information how long (roughly) it might take to migrate about 225GB usintg USB to FireWire? I want to plan for a time when i won't be able to use either computer.
thanks!

New setup questions...

Hey Guys,
I'm moving to a new condo on 9/1 and getting Fios (switching from cable) for the first time. In the proverbial nutshell, what I want to do is this: run two HD TiVos (with cablecards), plus my Apple Time Capsule as my primary router. I don't care a bit about VOD or Verizon's channel guides, email, or any other silly thing they provide. An ISP is (or ought to be) just a 'dumb pipe'.
Having done some research online today, it seems as though I need to have my ONT set up to run Ethernet, not MOCA (coax). Is there anything else I've missed that I need to know?
Thanks! Any suggestions greatly appreciated... :-)
Regards,
Ken

You would want to have a CAT5 Cable run from the location where the ONT will be to where your Apple Router will be locatated.
Allow the FIOS Technician to install their Router and get everything up and running. Since you are not planning on using the Verizon Router the location should not mater. I would just have a CAT5 Patch cable available and ask them to use it to make the data conenction from the ONT to the Verizon Router.
Once the technician is done you can release the TCP/IP Address from teh Verizon Router, Power Down, Swap in your Router, and hopefully be all setup. Here is a FAQ with more information on using different routers:

Need advice about migrating data

I just bought my daughter a new MacBook. She launched the Migration Assistant tool to transfer her data from her iMAC. Both computers are running Leopard, and the iMAC is just 1 year old. The problem is that she set up the transfer to go through our home wireless network, which is only wireless G, and the computers indicate the transfer will take 18 hours.
My question is this: Can I just click off the transfer and start another transfer approach that will be faster? For example, when she first started working with the iMAC, we migrated about 25 GB of data from a Windows machine using an external hard drive that was the back-up drive for the Windows machine. This transfer occurred very quickly, well under an hour. Is it possible to transfer the data directly from the Time Machine external drive, which had been attached to the iMAC, to to the MacBook using the USB ports (there is no Firewire port on the MacBook, believe it or not)? I should be able to just copy the data files and paste them into the new MacBook, just as I did when I transferred her data from the Windows maching to the iMAC.
Any comments or suggestions would be much appreciated.
Thanks,

seeker,
This KB article has some suggestions for migrating data for the new MacBooks.
[http://support.apple.com/kb/HT1291]
Also, an ethernet cable between the 2 Mac should work great for you. The info below might be helpful as well.
You shouldn't have a problem re-trying the migration again. If Migration Assistant detects duplicate user accounts it will give you the option to overwrite them with the new copies or rename them.
*Using Time Machine Before Initial Launch of New Mac*
Before starting the new Mac for the first time, attach the hard disk that contains the Time Machine backups from the old Mac. (For Time Capsule/AirDisk users: If you will be attempting this wirelessly, ensure that you are in range of your Airport wireless device. Alternatively, for faster migration of large quantities of data, connect your Mac via ethernet to your wireless device.)
Procedure:
Startup the new Mac and begin the setup process. You will initially see the video introduction.
At “Welcome” select your country and then preferred keyboard.
At “Do You Already Own a Mac?” you are asked “Would you like to transfer your information?”
+from another Mac+
+from another volume on this Mac+
+from a Time Machine backup+
+Do not transfer my information now+
Select “from a Time Machine backup” and click “Continue”.
At “Select a Backup Volume” choose your Time Machine backup disk and click “Continue”. (If you are attempting the migration wirelessly, then click “Join...” and select your network first.)
At “Transfer Your Information” check all the categories you wish to migrate over. If you wish your Mac to be in the same state as your last backup, then check everything. If, however, you are only interested in transferring one user account, then click the little disclosure triangle next to "Users". A list of all the previous users will appear. Just uncheck the user accounts you do NOT wish to migrate over. In other words, have only the desired account checked.
Give the installer time to calculate sizes.
Once that is complete, the “Transfer” button will become active and you can click it.
After the migration, verify the registration information, click “Connect” and you are done.
Once the migration is complete use Disk Utility to repair any permissions issues.
*Using Time Machine After Initial Launch of New Mac*
If you happened to initially set up the new Mac using a different username than the username on the account you wish to migrate, then skip to “Attach the hard disk containing...”.
If, on the other hand, it is the same username as the account you wish to migrate over, then do the following:
Go to System Preferences --> Accounts.
You may need to unlock the lock in the lower left to make changes.
Below the pane on the left click "+" and create a brand new Administrator User account on the Mac with a completely unique name - not the name of your own User account.
Now logout of the account you are currently in and log back in using the new Admin account you just created.
Attach the hard disk containing the previous Macs' Time Machine backups to the new computer. (For Time Capsule/AirDisk users migration will be much faster if you connect your Mac directly to the router via ethernet.)
Now go to Applications --> Utilities --> and launch Migration Assistant.
At the welcome dialogue click "Continue." You may be required to enter your Admin password.
For Migration Method chose "From a Time Machine backup or other disk". (Do not choose…
"Full System Restore" unless it is exactly the same Mac you are restoring to.)
At “Select the System to Transfer” choose the hard disk containing the previous Time Machine backups and click “Continue”. Give Migration Assistant some time as it connects to the drive and scans the disk for eligible data to migrate.
At “Select User Accounts to Transfer” put a check beside each account you would like migrate over to the new Mac.
At “Select the Items to Transfer” you can choose to migrate “Applications” over. If an application already resides on your new Mac, only the newest version will be transferred. Additionally, other “Files and Folders” that resided at the top level of your old Mac can be transferred at this point as well. Files from the “Library” folder of your old Mac will always be transferred over unless you uncheck the other two options.
Click “Continue”.
At “Select Computer Settings to Transfer” choose which settings you would prefer transferring to the new Mac. If you want a completely fresh system to start with, then do not check any of these options. This can be helpful if your previous system was experiencing issues.
Click “Transfer”.
If you have already created a User Account on the new Mac and it happens to be named the same as the User Account that is being migrated then Migration Assistant will report,
+"There is an existing user account with the same name as an account you are transferring."+
At that point, you will be able to choose one of the following:
+• Rename the user account you are transferring+
+• Replace the existing user account with the one you're transferring+
+• Do not transfer this user account+
If you wish the new Mac environment to be exactly the same as your old Mac, then avoid selecting “Rename the user account...”. Rather, select “Replace the existing user account...”. It will not be deleted but saved in a new folder labeled “Deleted Users” found in the main Users folder. Click “Next”.
At this point the transfer will begin with a bar displaying the progress. Once completed click “Quit”.
*Full Backup After Migration to New Mac*
Bear in mind that in all cases Time Machine will not continue to backup the previous Macs’ backup sets but will perform a new full backup. This is normal. Time Machine will resume incremental backups after the full backup has completed. To view previous backups, Control-click or right-click the Time Machine icon in your Dock or Option-click the Time Machine menu extra and Choose "Browse Other Time Machine Disks," then select the previous Mac’s backup set. You will enter Time Machine and be able to browse your previous back ups and restore files. [http://support.apple.com/kb/TS1338]
Let us know if this resolved your issue.
Cheers!

How best to migrate data to retina macbook

until the thunderbolt firewire adapter is available, what is the best method to migrate data to a new retina macbook?

I have to agree with Kappy. I've used Carbon Copy Cloner for every Mac migration I've done for the past several years. It's as close to a flawless piece of software as you'll ever find. Even though I use (and am a fan of) Time Machine using the Time Capsule functionality of a QNAP RAID NAS via WiFi, I also use CCC to make frequent clones of my two drive partitions. I typically use two partitions (3 now with Apple's recovery partition) – an OS boot partition and a data partition. For security and speed-of-recovery, the home directory for my primary user account lives on the data partition. While Time Machine does it's delta-based sparse bundle backup, I routinely do exact clones of each drive partition onto a like-partitioned external Go-flex Firewire drive. When my MacBook Pro was stolen last year, I restored from the CCC backup which was about three weeks old and then did a Time Machine restore on top of it. Since I was out of town when the computer was stolen, the Time Machine backup was current as of three days earlier (when I was home and TM ran automatically over Wifi). Considering they stole a new 17" MBP with a 500GB SSD, losing only three days of data was a godsend.
I've ordered a MBP Retina. When it arrives, I'll migrate to it the same way, using CCC. The cool thing about the Seagate GoFlex system, by the way, is that I can switch a drive from Firewire 800 to USB 3 by swapping a $19 adapter.

Bought a new Mac, migrated data, now CS4 doesn't work. Why?

I bought a new Mac, had the Apple guys migrate my data and apps to it. Now CS4 doesn't work.
I researched a bit and found that I SHOULD have deactivated and uninstalled CS4 from my old Mac. I've now done that.
But do I have to uninstall CS4 files from my new Mac now--and reinstall? Will that work?

Hi,
I have a question related to one you answered above: "bought a new Mac, migrated data, now CS4 doesn't work."
My situation is a little different. I am hoping you can help me with it. I hope I am not violating any protocols by asking you specifically? A year ago I reinstalled my Mac's operating system. My CS4 is on my computer under "Previous System." I am unable to open it from there and I do not want to attempt migrating it for reasons noted above. I did try to reinstall it as you suggested to hbrady67 by dowloading from CS4 products with my serial number but I got this message: "Upgrade Check We looked in the default location for qualifying products installed on the machine, but none were found. You may verify upgrade eligibility now by completing the fields to the right. 1) Select a product you already own. 2) Enter a serial number for this product. CS4 wasn't in the list of selections. The protocol suggested won't work for me since I am not doing an upgrade but trying to reinstall what I already have. Can you direct me on where to go/what to do? Thank you very much. Bergi.
I found the solution to this problem. I was able to download the trial version of what I have and enter the serial number from there. However, it still asked for a serial number from previous software: "your setup is for an upgrade version of Adobe Creative Suite 4." (I entered the serial number that I have for CS2. And it was accepted. Thank you. Bergi

Does Migration Assistant copies all iTunes/iPhoto data to the new Mac?

I currently placed all my iphoto and itunes data on an external harddrive in my current setup. I have a MacMini 2010. Im planning to upgrade its HARDDRIVE with a smaller capacity but faster SSD.
So here goes my question... (the fact is, i haven't tried Migration Assistant ever, hence these troubling questions..)
I would keep my old harddrive intact as it used to be. I would install the SSD on the MacMini and do a clean install of OSX Lion which is also the current version of my OS in the old HARDDRIVE. I'm planning to attach the OLD HARDDRIVE using an HD enclosure and connect it using USB/Firewire externally. If i use, Migration Assistant to copy my settings and files in the OLD HARDDRIVE, will it also copy all my itunes/iphoto data into the new SSD? (music and photo data that are stored in an EXTERNAL HARDDRIVE right now) - meaning itunes and iphoto data folders are in an external hard drive.
I'm pretty sure it wouldn't fit. Im hoping itunes and iphoto would just LINK all those files as it used to be on my EXTERNAL HARDDRIVE and NOT COPY it to my small capacity SSD.
Do you get it? Please ask me if you don't. I just want to make sure a smooth transition to the new SSD if i push thru.

You can restore your iPod to "New" which will erase every thing and install fresh iOS software or you can restore to a particular backup that you have previously created. In this case, your iPod Apps & data will appear as per the backup. Note that some content is not in a backup and will need to be synced back to the iPad from the iTunes music library or from, for example, the iPhoto photo library.

We are currently in the process of migrating out vmware infrastructure from HP to UCS. We are utilizing the Virtual Connect Adapters for the project. With the migration we also plan on implementing the cisco nexus v1000 in our environment. I have demo equipment setup and have had a chance to install a test environment, but still have a few design questions.
When implementing the new setup, what is a good base setup for the virtual connect adapters with the v1000? How many Nics should I dedicate? Right now I run 6 nics per server (2 console, 2 Virtual Machines, and 2 Vmotion). Is this a setup I should continue with going forward? The only other thing I am looking to implement is another set of nics for nfs access. In a previous setup at a different job, we had 10 nics per server (2 console, 4 virtual machines, 2 vmotion and 2 iSCSI). Is there any kind of standard for this setup?
The reason I am asking is I want to get the most out of my vmware environment as we will be looking to migrate Tier 1 app servers once we get everything up and running.
Thanks for the help!

Tim,
Migrating from HP Virtual Connect (VC) -> UCS might change your network design slightly, for the better of course . Not sure if you're using 1G or 10G VC modules but I'll respond as if you've using 10G modules because this is what UCS will provide. VC modules provide a 10G interface that you can logically chop up into a max of 4 host vNIC interfaces totaling 10G. Though it's handy to divide a single 10G interfaces into virtual NICs for Service Console, VMotion, iSCSI etc, this creates the opportunity for wasted bandwidth. The logical NICs VC creates provides a max limit of bandwidth to the adapter. For example if create a 2GB interface for your host to use for vMotion, then 2G of your 10G pipe is wastes when there's no vMotions taking place!
UCS & 1000v offer a different solution in terms of bandwidth utilization by means of QoS. We feel it's more appropriate to specifiy a "minimum" bandwidth guarantee rather than a hard upper limit - leading to wasted pipe. Depending on which UCS blade and mezz card option you have, the # of adapters you can present to the Host varies. B200 blades can support one mezz card (with 2 x 10G interfaces) while the B250 and B440 are full width blades and support 2 Mezz cards. In terms of Mezz cards now, there's the Intel/Emulex/Qlogic/Broamcom/Cisco VIC options. In my opinion the M81KR (VIC) is best suited for virtualized environments as you can present up to 56 virtual interfaces to the host, each having various levels of QoS applied. When you roll the 1000v into the mix you have a lethal combination of adding some of the new QoS features that automatically match traffic types such as Service Console, iSCSI, VMotion etc. See this thread for a list/explanation of new features coming in the next verison of 1000v due out in a couple weeks https://www.myciscocommunity.com/message/61580#61580
Before you think about design too much, tell us what blades & adapters you're using and we can offer some suggestions for setting them up in the best configuration for your virtual infrastructure.
Regards,
Robert
BTW - Here's a couple Best Practice Guides with UCS & 1000v that you might find useful.

Data Migration from R3 to new ECC System

Hello,
We are doing a fresh implementation for SAP MDM. Currently we have 3 SAP R/3 systems and 1 non-R3 system (BPCS system). One of the project goals is to do data migration from all these 4 systems into a new SAP ECC system and to MDM for Vendor Master, Customer Master and Material Master. My manager says that we need Business Objects tool to Migrate these data. But, my question is that is it not possible to achive this through XI/PI itself ? Can anyone let me know the entire process in XI/PI as to how do I receive the Idocs from R/3, convert into XML and then send it to the new ECC system in Idoc format ?
Thks & Rgds,
Hema

Hi Gandhi,
You have SAP MDM, BPC and R/3 systems in your landscape, when you are migrating data to new ECC system, what is the role of mdm, did you moving the same data to MDM to avoid duplicate/redundant data??is there any data migration from R/3 to MDM(any integration required)or MDM to R/3,
You have to develop different interfaces to transfer data from MDM to ECC, BPC to ECC.definelty you required one middleware, the option definitely SAP PI. it offers very easy of integration between MDM and R/3 system, you can use MDM-PI adapter to connect to directly MDM syndicator file port from there you can pull the XML file and convert it in to IDoc format use Receiver IDoc adapter in PI, the same way we can integrate BPC system with R/3.
Search in sdn, there are some scenarios integration of R/3 and MDM using PI, refer those links, if still you have any doubts let me know,
Regards,
Raj

Migrating Data from old iMac G5 (PPC) to new iMac QC i7

I have had an iMac G5 PPC for about 6 years. The logic board just died about 2 weeks ago.
I am about to purchase a new 27" iMac Quad-core i7 machine, and I am wondering what is the best way to migrate data from the old machine to the new one.
I have a few different questions...
I use SuperDuper! to backup, so I do have a full copy of my hard drive on an external drive. But the data is about 2 weeks older than the hard drive on my G5 (meaning, I backed up about 2 weeks before the machine died, so there is data on there that I'd love to retrieve). I understand that I can pull the hard drive out of the iMac G5 and buy a cable to attach it to the new machine. I also understand that I can attach my external drive (with the SuperDuper! copy of my hard drive) to the new iMac, too, and run Migration Assistant (or Set Up Assistant) to transfer data.
However, I have heard that it is not good to do a straight migration from a Power PC to an Intel machine.
Is that true?
I would ideally like to transfer all my email (tens of thousands of them), my iPhoto library, my iTunes library, iCal, many many documents, and some other random stuff.
What do you recommend?
Should I do an automatic migration using Set Up Assistant and my external hard drive with the SuperDuper copy?
Should I (and can I?) do an automatic migration with the hard drive that I pull from the old machine?
Or should I (can I?) do a manual migration whereby I only copy the folders/files/libraries that I really want, and avoid clogging up the new machine with PowerPC apps, etc., that the new (Intel) iMac might not like?
This last one seems like the ideal choice, but I am not sure...and I don't know exactly how to go about that process.
Apologies for the long post, and many thanks in advance for any help anyone can offer.
Best,
Matt

automatic migration works well for most people but problems are possible both because of architecture and system differences.
I would ideally like to transfer all my email (tens of thousands of them), my iPhoto library, my iTunes library, iCal, many many documents, and some other random stuff.
What do you recommend?
you can try automatic migration first. if you are worried about possible problems you can choose to migrate user data only but no applications. this should reduce the likelihood of conflicts. but if you run into problems you can always erase and install and do manual migration. since you have a superduper backup this option is not going away and is always available.
see this link on how to go about that

This last one seems like the ideal choice, but I am not sure...and I don't know exactly how to go about that process.
Apologies for the long post, and many thanks in advance for any help anyone can offer.
Best,
Matt

I am wondering about transferring my pc date to my new iMac. I know there is a migration assistant, but I have multiple drives in my pc. Will the migration assistant be able to handle this?

I know there is a migration assistant, but I have multiple drives in my pc. Will the migration assistant be able to handle this? I'm going to be trying to move the date to a new imac 27' with fusion drive.

the following set of instructions is a little longer, so you might want to print it out and have it handy
Step 1 - PC
If your PC already is connected to the Internet, hold down the Windows button on
your keyboard and simultanously press R. Into the opening window enter "cmd" (without
the quotation marks). A command line will open, enter "ipconfig" (again without the
quotation marks) at the prompt. Now find the section labelled "Ethernet-Adaptor" and
note the values for IP-Address, Subnet-Mask and Default-Gateway on a sheet of paper
If your PC is not already connected to the internet, you need to manually configure its IP address.
open Network and Sharing Center
do a right click on Ethernet and select Properties
in middle of the screen there is a box labelled "This connection uses the following items"
out of this box select "Internet Protocol Version 4 (TCP/IPv4)"
click on the Properties button in the right corner
Into the window "Use the following IP address" enter the following values
IP-Address: 192.168.0.1
Subnet-Mask: 255.255.255.0
Default-Gateway is the IP-Address of your Router. This value is needed for internet connection, for the file sharing setup only this value can be left empty.
Step 2 - Mac
If your Mac already is connected to the internet, it is likely that it has automatically receive the necessary parameters from your router and therefore should be in the same network as your PC. To be on the safe side, you can check this by
open System Preferences
select Network
choose Ethernet from the panel on the left side of the window
click on Advanced
click on TCP/IP
compare the values for IP-Address, Subnet-Mask and Default-Gateway with those you wrote down earlier.
If both PC and Mac have identical numbers in the first three parts of the IP-Address, you are set.
If your Mac is not already connected to the internet, you need to manually configure its IP-Address as well.
In the TCP/IP window you have just opened select "Manually" from the drop down menu "Configure IPv4:"
Enter the following values
IP-Address: 192.168.0.2
Subnet-Mask: same as with PC
Default-Gateway: same as with PC
Step 3 - Activate File Sharing on PC
open Control Panel
select Network and Internet
select Network and Sharing Center
on the left panel select change advanced sharing settings
in the middle of the new page enable turn on file and printer sharing
Step 4 - Activate File Sharing on Mac
open System Preferences
select Sharing
set check mark next to File Sharing (green circle appears on the right side next to File Sharing:)
click on Options:
set check mark next to Share files and folders using SMB
in the listbox under the text Windows File Sharing make sure there is a check mark next to your account name
Step 5 - Create a share on your PC
In Explorer select the folder you wish to share
do a right click on that folder and select "Share with"
choose "Specific people"
a new window opens. there select your Windows username (usually the first in the list)
if you plan to copy from Windows to Mac only, it would be sufficient to grant Read permission only, but, since most likely you are the only person to access that share and certainly do not plan to sabotage yourself, Read & Write permission is ok too.
finally click on "Share"
Step 6 - Create a share on your Mac
Once the check mark next to your account name is set (see above) your home directory is automatically set as a share.
Step 7 - Connect your PC to your Mac-Share
do a right click on the network icon which resides on your desktop or in the left
panel of every Explorer window
Select Connect Share
in the text box next to Folder: enter \\<ip-address-of-your-mac>\<your-osx-username>
if you are using the same username and password on both Windows and OSX click on "Finish",
if not set the check mark next to "Connect using different credentials" afterwards click on "Finish" A new window will open where you enter username and password that you are using with OSX
Step 8 - Connect your Mac to your PC-Share
hold down the command key and press K simultanously or in Finder click on Go in the menu at the top of your screen and select "Connect to Server"
in the Window that opens enter smb://<your-windows-username>:<your-windows-password>@<ip-address-of-your-PC/<y our-windows-username>
or
smb://<ip-adress-of-your-PC/<your-windows-username> you will be asked to enter your Windows username and password in popup window
Now you have both computers connected to each other. Each will provide you access to your home directory of the other computer. Open a second Explorer or Finder window with your local home directory and start copying

Can't migrate date from old mbp to new mbp using maverick

Hi have a new MBP 15 and 1 old one 12 maths old bothe running maverick. Have been trying to migrate data from older MBP but they keep disconnecting as soon as the transfer is about to start.

Use the Setup Assistant during your initial setup of the new computer. You will need to connect your old computer to the new computer to do this. You can do this using a current Time Machine backup of the old computer if you can connect the backup drive to the new computer. See Target Disk Mode and About Windows Migration Assistant.

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on external drive. I'd like to migrate only the internal hard drive data to the new internal Drive then just plug in iPhoto library drive. Is this going be a problem?

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on an external drive. Both drives are backed up on Time Machine. I'd like to migrate only the old internal hard drive data to the new internal Drive and then just plug in iPhoto library drive to the new iMac. This would save having to transfer several hundred GBs of data. Will this work using Set Up Assistant?

Your user account on the new Mac must have a different UID than on the old one. See the pink box in Problems after using Migration Assistant for an explanation.
You'll need to change the permissions on the iPhoto library on the external HD. Do a Get Info on it, click the padlock at the bottom of the Sharing & Permissions section of the Info window and enter your Admin password.
Then click the plus sign, select the user account you want on the next screen, and click Select. Then change Read only to Read & Write for that user via the little arrows. Finally, click the "gear" icon and select Apply to enclosed items. That may take a few mintutes on a large library.

Am being prompted to enter security questions when making a purchase on my new IPad. I don't believe I have ever setup security questions on my apple id. How to I create new security questions?

I am being prompted to enter security questions when making a purchase on my new IPad. I don't believe I have ever setup security questions on my apple id. I have tried logging into my apple id and have chosen the security and priviacy settings to set up security questions. However I am prompted to enter answers to security questions and am told they don't match. How to I create new security questions or reset them?

You need to ask Apple to reset your security questions; ways of contacting them include phoning AppleCare and asking for the Account Security team, clicking here and picking a method for your country, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.
