I have a Macbook Pro 13-in. mid-2012, OS X Yosemite 1010.3.
I recently upgraded the RAM from 4 GB to 8 GB using Apple's guidelines:
After replacing the screen and booting the system, I opened up Chrome. Whenever I type/scroll, the web browser flickers. Not the screen, just the web browser.
Any ideas what the problem is? My guess is I didn't place the RAM in correctly. Also, after lifting off the back case, I did spray the inside with canned air (as recommended, I thought) to clean the system of any dust. Would this forever damage the system?
Is it possible this is a static electricity issue? I have my doubts.
Any insight is appreciated, thanks!
EDIT: Another thought: maybe I touched the RAM cards incorrectly and damaged them? Is that possible?
