I am forced to sell my 2009 unibody macbook. 2.26GHz 8GB ram 240GB SSD running sierra. My car needs an MOT and few bits. So it is sold just waiting on payment. Anyway I have to use my 17" Santa Rosa pro. it is 2.4GH 3GB ram and 500GB HDD running El Capitan. I use my mac for work and with my unibody when at work with usual apps running the monitor app shows I use little over 4GB ram. The pro has 3GB ram. Is the swap file on a HDD going to impact speed/running of apps severely? The laptop will take 4GB ram max. I'd rather not spend much on it as I am trying to put some money aside for another macbook once car done. These are what I have open at work: Chrome with 3-4 tabs Firefox with 1-2 tabs Thunderbird Skype imessage And some times need open word or excel, but when done I always quit not just close it. thanks for any help.
