Hi guys, I have a 128GB ssd and it's finally completely filled up with applications crashing. I'm unable to make any more space as primary consumers of space are my itunes and iphoto libraries which I'm unable to reduce. So I thought why not upgrade my ssd. I called up Apple retail store and was told that one can't upgrade the ssd on a macbook air because everything is fixed in place and the slightest mistake could scatter the lithium polymer from the batteries everywhere. My reaction was: wtf. My ssd is full and I need to upgrade. Are you telling me I need to buy a brand new mac?! Anyway, what can I do here? Can anyone recommend a shop in London which will do the upgrade from 128GB to 512GB SSD for me? Many thanks.
