I have a SSD (Boot Partition) and a HDD (Data) for my Mac. I only bought a 128GB SSD thinking the boot partition wouldn't need a large drive, however I was mistaken.
I find that Mail and MobileSync folders in my Library directory take the majority of the storage on my SSD sometimes even bringing 'Low Disk Space' prompt if I don't watch it for a while and let it loose.
I wanted to know if I use symlinks to create the following directories in another location would they work correctly or cause problems? ~/Library/Mail ~/Library/MobileSync
