Hi, since I bought my new MBA 2011 I was in searching how to install SL on it cause I don't like Lion at all. I finally maanaged to install it fully working and since there are a lot of people here who wants to do that here what you'll need
1. MBA 2011
2. Snow Leopard Retail DVD
3. USB flash 8GB or more
4. external display (and the cable to connect it to MBA obviously)
5. Another USB or SD card
So first you have to make it the usb drive an install disc. Here's how
https://forums.macrumors.com/threads/1011768/ (follow the instructions made by sup3r1or
then you have to download the attached file to your second usb flash/sd card
then insert the usb in your MBA restart and while booting hold down the option key which will ask you from which disk to boot. You have to choose your flash drive (the USB one). Then you have to format your Lion partition (and all the data on it so make a Backup first). Once done you can freshly install Snow Leopard. After installation you will probably get stucked on the startup screen. Don't worry it's just a missing driver. Then Connect your mac to the external Display and you'll see the new freshly installed Snow leopard. From here you can make the system update to 10.6.8 and then insert the drive with the attached file (which is a kext) into the air and install it, repair permissions reboot, aaand you're good to go with Brand new snow leopard installed
