View Full Version : Having trouble understanding the Yosemite - Slowing my MBA

23rd June 2015, 02:56 PM
Hi guys,

Sorry to bother some of you but I am having difficulty in finding the reason why my macbook air is so slow after upgrading to yosemite. Apart from RAM issues, would there be any other issues? I've searched high and low and found some help on the apple community forum but I kept on getting to a page not found site which prevents me from posting anywhere there. Any help here is much appreciated.

I ran a software called EtreCheck. See what you can make sense of this.

It's pretty much the lack of RAM. It states in your log you've used it and moved to swap.
You have an SSD but I don't know how fast it actually is.

Either return to 10.9, close apps that aren't being used at the time, or sell it and get one with 8GB RAM.

You've also got an app, or more likely a daemon, called "powerd" that was using a lot of proc when you ran the test. If that's a frequent occurrence it will be slowing things down too.

10.10 Shouldn't be that much more RAM heavy than 10.9 was - Ram does seem to be your limiting factor though here... Thus why Apple only putting 4GB of ram in their 2015 Airs is borderline criminal...
