OS X Lion slowing down MacBook.

[graceso]

I downloaded OS X Lion to my MacBook (2010) four or five days ago and ever since then, everything has slowed down. I almost always have to force quit applications, scrolling is slow, and just simple things like switching tabs on safari take more than a minute. Is there anything I can do to fix this issue?

 

[stefan1975]

yes, there is one remedy. install SL.

yeesh. perhaps re-installing Lion would help...

 

[graceso]

How would I do that?

Thanks for you help!

How much RAM you Macbook have? 4GB is the new minimum recommended.

A clean install of Lion did not help my machine.

Going back to Snow Leopard did.

Last resort I'd say repair ur permissions, reset pram and reset smc and see if that helps.

The thing that was slowing down my MacBook in Lion was Safari. There's a memory leak and the amount of RAM Safari was using would creep up the longer I had it open. It even reached 1.3GB of RAM at one point and I only had 3 tabs open!

I switched to the WebKit nightly builds, but it had the same issue too, until this most recent build (which I haven't seen the amount of RAM gobbling that I have in the past). Also, Firefox 6 Beta is freakin' fast in Lion with no memory leak issues

You think 1.3GBs is bad, try 5.71GBs with 2 tabs on bestbuy's website. It actually reached over 6GBs before I forced quit the program. Haha

I've had the same problem with my 2GB Mac mini. Everything in general is slower than with SL.

I never thought I'd see the day when Safari's memory leaks surpassed those of Firefox. I feel like the new Safari has taken a lot of cues from Mobile Safari, I've had that suck down over 100 MB on my iPhone 4 with just a few tabs open. Lion's Safari also seems to want to refresh non-focused tabs automatically, probably where a lot of that memory is going.

I'll definitely be looking into the Firefox beta until Apple releases a Safari update. Thanks for the tip!
