Hello, since Windows work differently, I am posting here. I have a MacBook Pro 2010 17" with me right now. Between 2012-2014, I used a rMBP 15" 2012. In 2014-a week ago, I used a rMBP 15" 2014. In add three machines, I used Bootcamp and installed Windows 7 in the Bootcamp partitions. I used Winclone to backup the Windows partition. I am waiting for the up-coming new Mac laptop which might be available in March or May. After upgrading to EI Capitan, the performance of my MBP 2010 17" became slow. I checked. Mail is not the cause for the slowdown. 1. Since I have been using MBP, will there be issues if I restore the backuped Windows partition (using Winclone) on a MacBook or MacBook Air? 2. If I buy a Surface Pro 4 or MacBook, will I be able to put the backuped Windows parition to any of these machines? 3. If I upgrade the HD of my MBP 2010 17" to SSD, do you think I will have issues given that rMBP 2012 and rMBP 2014 have more advanced hardware. I guess I might have to use the Windows installed on this laptop as the base and manually copy the files from the Windows partition of rMBP 2012 and 2014. Any suggestion appreciated. Thanks.
