Sharing Hotspot from the mac that the iPhone or iPad can connect with? Is it possible to share a kind of "hotspot" from my macbook so that the iPhone and iPad can connect with it? Just like there is a "personal hotspot" feature on the iPhone I want it the other way around. 

The reason I'm asking is that I'm in a room where I have absolutely NO internet. Wheter 3G on my iPhone nor any wireless or ethernet connection.

Is there any chance I can create my own "internal" wireless network outgoing of my mac and connect my iPhone and iPad with it so that it has a regular IP etc. 

I need this because I want to demo a Website that is built for mobile devices. I have a local apache server on my mac and usually develop and test with "Adobe Shadow" (meanwhile Adobe Edge Inspect). This works great usuaslly when all my devices are in the same network. However in this room there is no network so I wonder how I could create my own network.

Any ideas about that?
You can create a Personal Network from the AirPort (Wi-Fi) menu.


Select Create Network ...
Define a name for your Network
Select the channel
Select the security (if selected, define a passphrase/key)
Click Create.




In my case I also have to define the IP addresses on the devices.

On your MacBook:


Go to System Preferences
Network
Select the Wi-Fi connection
Click Advanced
Select the tab TCP/IP
In the first field select the voice Manually
Set an IP (e.g. 192.168.1.1)
Set a Subnet Mask (255.255.255.0)
Click OK


On the iOS devices:


Go to Settings
Wi-Fi
Click the blue arrow on the righ of your ad hoc Wi-Fi connection
Select the tab Static
Set an IP (e.g. 192.168.1.2)
Set a Subnet Mask (255.255.255.0)
