I find 99.999% of the blockchain irrelevant and a wasteful use of storage space in my personal computers. I just need it to sync my wallets.

on OSX what are bitcoin softwares that do not require downloading the entire blockchain? How can I find the wallet of my currently installed software (Bitcoin-Qt) and move it

Electrum wallet. Works like a charm on my mac.

  • An electrum wallet is a series of addresses based on a seed: electrum.org/seed.html Use your bitcoin-qt client to pay yourself at one of the addresses that you get from Electrum.

MultiBit is available for OSX. https://multibit.org

This only uses the block headers (included in the download - about 20 MB). There is a version in test that replaces this with a checkpoints file which is only 12 kilobytes.
