After browsing through multiple posts, I finally was able to install Qubes on a MacBook Air 13” mid 2011 (MacBookAir 4,2). Im just sharing this, so ppl dont need to read through multiple forums to understand how to do it.
This model is features with:
• Dual Intel i7-2677M 1.80 Ghz CPU (2 dual cores)
• Intel HD Graphics 3000
• 4Gb RAM
• 256Gb SDD
Broadcom BCM43224 802.11 a/b/g/n wifi and Bluetooth adapter
• Intel DSL2310 Thunderbolt controller
It has 1 DVI/Thunderbolt display port, 2 USB2.0 ports, a Magsafe power adapter, a standard 3.5mm audio jack and SD reader.

First try to install Qubes using the UEFI boot failed, and not wanting to waste too much time, I quickly opted for the legacy BIOS install.

If you try to boot Qubes now, it will freeze while “setting up networking”. You need to put the Broadcom wireless device into PCI passtrough [2,3]. Or, as an alternative remove it from your mac (https://www.ifixit.com/Guide/MacBook+Air+13-Inch+Mid+2011+AirPort-Bluetooth+Card+Replacement/6360) and Qubes will boot up smoothly.
If you choose to remove the card jump to step 3.
