I recently upgraded from Snow Leopard to Lion and have noticed that I get the rainbow wheel a lot more often, and everything in general just seems a bit slower. I've decided to format my iMac's internal hard drive and install a fresh copy of Lion on it. I have already backed up everything with Time Machine. My question lies with how I will be able to recover all my apps and their settings, ect. after I have formatted and installed a new copy of Lion? Will I have to manually install each one again and change all the settings manually, or is there a way to restore all my apps from Time Machine on the newly formatted hard drive? Thanks.
