CAN I BUY MORE RAM FOR MY MacBook Pro 13?

Get a large external Solid State Drive/s (SSD) as big as you can afford or require.

1 or 2 Terabytes is a good place to start.

Prices are very affordable these days.

You assign any new Libraries to the SSD and work off that. Always have a backup strategy in place.

Tip: if you buy a drive dock you only need the bare drives.

When you say "more room" are you referring to you storage space for Libraries.
