Can I overfill memory and will it slow computer?
My MacAir is very slow. it shows 2 gb memory but 2.12 GB in iPhoto use age...is that the problem?
There is RAM whichn is the memory the CPU uses for data. In computer there is also stroage which is either a Soloid State Drive or a disk drive. This is where your Mac stores data when is is shutdown.
The 2.12 GB is space on the storage and has nothing to do with RAM.
How full is the storage on your Mac?
