3g and 4g are mobile phone wireless networking so they aren't part of any computer.
You can get a 3g type "router" to hook to the computer to use a 3g network or you can use your computer to connect to a smart phone via Tethering where you use the phones network.
A wireless mouse for the Apple computer can be ordered on the internet website for Apple. You must specify what kind of computer you have before ordering.
Try it, If not call apple.
I'm pretty sure the answer to this is "yes". I'm only stating this from personal experience, though. I have a Macbook and my mom has a PC laptop. The wireless internet router at our home is not by Apple and the wireless internet works on both of our computers.
Once you have your WiFi network up and running, give the network a name, just turn on your Mac and then click System Preferences > Network and turn the WiFi on. Your Mac will pretty much do the rest and will connect the the network.
The only apple devices that have constant internet are those with 3G or 4G, i.e. iPhones. iPads and iPod touches are welcome to surf the Internet if you are near a WiFi Hotspot or have Broadband in your home (go to Settings>WiFi and click on a wireless Connection).
No, they will not work.
Apple's iBook laptops can connect to the Internet. The early versions of the iBook did not come with an AirPort (Wireless) connection - you needed to add an Airport card - so will need to be connected through a wire - usually an Ethernet cable plugged into the router.
I depends if the software on the usb device is compatible with mac. I have used an At&T one with my mac.
First, you need to have a wireless router. Second, install an airport card to the laptop.
Many companies sell wireless access points. Apple makes a good one that they call an "Airport," but you can only use it with macs. If you have a PC, try something by Linksys or Belkin.
An iPhone is a certain line of smart phones shipped worldwide under the platform of Apple (maker of the iPod and iMac). The "i" used to stand for "Internet" at the time of the first iMac when Internet connection was not wireless often. It is not the vanity letter of Apple products. You can learn more about the iPhone at Apple's website. http://www.apple.com
I am on a Mac connected to a wireless network. You either already have the built in adapter for the wireless network or you can purchase one. If you have it installed, you either have the program to use it or can download it from the internet. Go to the apple in the upper left hand corner and press it. You may see, "About this Mac." Click that. You will see Network. That will tell you what is on your network and if you already have wireless installed. If you do not, you will need to purchase a wireless unit. Go to google. Try "Apple Store." They will have a phone number. They will probably sell you something or at least tell you what to purchase. If it is installed, get out of that. Go to the apple again. Go to system preferences. You will need to enable wireless.
