If you already have a Mac with a CD drive, your best bet is to load the CD into the drive, and copy the installer disk image file (*.dmg) to a flash drive, or upload it to a file sharing service like Dropbox, and move it to the laptop that way. (The installer disk image file can be copied from place to place even if you can't run the installer on the iMac.) Then when you open the .dmg file on your laptop, it will create a virtual disk window with the application in it that you will move to your Applications folder. Restart the laptop just to be safe, then launch turbotax. It will need to install the latest update before you can start preparing a tax return.
