Every time I switch on my MacBook Air it says the start up disc is full and I need to delete files.
I mainly use my laptop for photos so imagine this is what it taking all the memory up. I also synch my iphone and apps to it.
This is probably a really silly question but I don't know how to delete files from the start up disc (or even what it is as there aren't any "discs" / no disc drive)
Any advice greatly appreciated.
TIA.
