I upgraded to Yosemite and it got a bit better, working smoothly for 10-20 minutes or so after start-up before starting to beach ball (heat issue?), but it was still pretty unusable for anything serious. With the OS version I was running (I think it was Mountain Lion) it was very bad, beachballing constantly. I had this problem with my mid-2009 MBP after upgrading to a Crucial 500GB SSD. Thanks to SmAcDuff for pointing out the solution to the Image scan error. After that, everything should go smoothly.

The source image needs to be imagescanned before it can be restored."Ĭlick on the image file in the list on the left and then click on Image in the menu and then on Scan Image for Restore. Sit, relax, and wait for the process to be done.ĮND: you have now downgraded to EFI firmware 1.6Ĭould not find any scan information. Once this is selected the Apple logo will come up and a dark gray bar will start to move right under it. Select the bootable USB drive (yellow orangish color), Use Arrows to navigate and Enter button to select. In my case I had three pop up, my Bootcamp partition my main Mac harddrive, and the BOOTABLE USB drive I just made.

Google: "Macbook Pro 2009 EFI firmware update 1.7."ĭowngrade the motherboard firmware back to EFI 1.6. This is a common know issue that Apple has not acknowledged.
