Sorry if this has been rehashed a million times, I can't find any clues in all the threads here. I'm struggling with a 2010 MBA, it was one of the rare ones that won't take additional RAM. Anyway it's getting slower and slower even though I created more space recently. Do you think it might happen in mid-September??? Trying to do things on my iphone but I am old school and am faster on the laptop. Thanks for any info!!!
