What you can do is bring up the wikicamps page on MacBook and then locate the square symbol with the arrow pointing up, this should be just right of the search bar at top of screen. Click this and then you will get option to save that page/link to your Home Screen. Click that option and the link to wikicamps will be permanently on you screen until you wish to delete it.
Then in future you just go to Home Screen and click on the link and it will open wikicamps.
You cant download the app into your MacBook, the above option is pretty much the same.
