Running DP4 & update here on a late 2008 iMac 4Gb ram, 2.2GHz dual core. It flies! It was just an update, no fresh install. I'm well chuffed with it.
funny thing I just noticed, Mountain Lion's xbench score is way worse than Lion's/Snow Leopard's on my C2D iMac 27". I'm quite surprised and somewhat disappointed... Animations, apart from Facebook scrolling in Safari and Mission Control with more than 10 windows are silky smooth though.
Is there a guide which explains how to do a clean install?OP here.... Well I took the plunge and did a clean install of ML on my 2.0 Core2 iMac.
The verdict?
Yes, it does bring the snappiness back to OSX. My machine feels nearly as snappy as Snow Leopard and the system just feels really smooth overall. All the animations that just crawled on Lion are now satisfactory (not perfect, but good). Boot and shutdown times are vastly improved over Lion and I'm really digging it overall.
I believe I may own the oldest machine that officially supports SL, but it really did breathe new life into my 5 yr old baby.
And in case you're wondering - my impressions aren't only due to a fresh OS install... Lion was always crap no matter how young the install.
I tried 10.7 three or four times on my mid-2007 iMac with a Radeon HD 2400. The hard drive has been swapped for an SSD, so the general performance was okay, but I found the animations in Lion to be so sluggish that it made my machine feel very laggy. I'm a heavy Expose user, so the Mission Control delays were unacceptable.
10.6 is smooth as silk, but many of the ML features look pretty appealing. Anyone have experience on a similar machine or graphics card?
Is there a guide which explains how to do a clean install?
Yes. Be sure you have a working time machine backup in case things go horribly wrong.I'll lose everything by doing it this way, right?
How long would it take?
Do you actually think it'll be worth it? Lion runs like trash on my Macbook 7,1 - maybe ML will fix this through an upgrade?
thanks.
