Hi guys! A couple of questions about my mid-2012 MacBook Pro 13". I'm running with 4GB of Ram. 500GB HDD (142GB used). 2.5GHz processor. It's a month old. 1. My right hand fan doesn't show up on iStat. Is it broken, or does the 13" only have a left fan? 2. I get lagging, at random times for no reason. That's whilst having over 1GB of RAM free. And reasons that could be causing this? Nothing major running in activity monitor. 3. Safari is very hungry on the RAM. Normal? 4. Finder just crashes out for no reason. 5. Applications can sometimes take an ageon to launch from cold. Other times the same application is nearly instant.
