Needed more RAM-memory and faster startup

Meu Problema

Sometimes my Mac "hung". The software I used needed at least 4 Gb Memory, but preferred 8 Gb.

Minha Solução

I replaced the RAM Chips by 2 x 8Gb Ram Chips and the standard Hard Drive by the SSD Hybrid one.

Meu Conselho

Everything was explained very clearly : I had no problems to fix it.
