Choppy Scrolling on MBA After Time Machine Restore
Just received my new 2013 MBA 13" i7 8GB 512GB SSD. During the initial setup I restored from my Time Machine backup (which was from a 2012 model MBA). Once restored I started using my new MBA and found the graphic subsystem to have a problem. Choppy scrolling in Safari, graphic stuttering, image tearing, using Lauchpad and scrolling between screens was awful. Interestingly, firing up Parallels and running Windows XP or 8 was just fine, but all OS X graphics were performing badly.
After Googling around for a solution, finally called Apple. We tried resetting PRAM and SMC, then tried reinstalling OS/X, problem still persisted. To find out if I had a hardware issue, I then formatted the Mac partition and did a clean install of OS/X. And it works perfectly. No graphics issue. Smooth scrolling on the exact web pages that were horrendous a couple hours earlier (it takes 2+ hours to perform the clean install).
So now we know it's something coming over from the backup of my 2012 MB Air (which is a 13" i7 8GB 512GB SSD model as well). The only question now is how to I get all my applications and data moved over without bringing along the unwanted graphics problem.
So with a completely clean install and the graphics problem gone I created a new admin user, logged into this account, and used the migration assistant which is different than the option to restore during the initial setup. I only say it's different because once it completed, I was able to login and everything was perfect. No choppy scrolling issues! For anyone else upgrading, I would be sure to use the migration assistant after logging into the machine and creating yourself an admin account different than the account you are about to restore.
