How to share the Wi-Fi from my iPhone 4s to my Macbook air?

My Wi-Fi only allows me to connect 2 devices so i picked my iPhone 4s (iOS7) and my iMac. I heard that only iPods and iPads can connect successfully to Macs but I don't know if thats correct.

1. Settings
2. Cellular
3. Personal Hotspot
4. Turn On
5. Enter Passcode for the Wi-Fi that you made on your phone, and enjoy the joint Wi-Fi

See my links under my name and look for router settings ianmccully on you tube and add you IP address from any device to connect your Wi-Fi or use your devices to connect to the rtouter thanks

If both then email or Google plus me at ianmccully thanks.

It's very easy, you just need to turn on the personal Wi-Fi hotspot on iPhone 4s. And you can see the exact steps from this, http://www.mywifirouter.me/blog/how-to-turn-iphone-into-personal-wifi-hotspot-device/

  • Should I get a MacBook Air or an iPhone 5S/5C? I got enough money to buy an iPhone for my birthday, but my mothers says that if I save my money until Christmas, I can get a MacBook Air. My phone is an old samsung galaxy ace, and it has all sorts of problems. It has very limited space and a very short battery life, and is super slow. My family's PC is slow, and is running out of space. I need that space for documents, and to be able to synch my iPad with iTunes. This is a really tough decision, please help!
  • Should I buy the iPhone 5 or Macbook Air? So I'm saving to get one of them but I'm not sure which one! I already have a phone but it's the Nokia C3-00 so it's quite old and I've had it for about 2 1/2 years now. I don't have my own laptop but I share one with my mum and I can use it after school only and I can't take it to school because she uses it for work. (The laptop is an HP laptop not an Apple product.) I also have an iPad Mini.
  • Is the $999 2012 11 Macbook Air good enough for iphone game/app development? I want to make games and apps for iphone and ipod touch so bad but not sure if the specs of the 11" 2012 mba are good enough seeing that the processor is at 1.7 ghz. I plan on upgrading the ram when i buy it to 8gb. Will this mac be good enough to develop games and app for iphone and ipod touch smoothly?
