Does anyone know from where i can hire a laptop or PC for a short time in or around Basel?
Thanks for the suggestions....
P.N I have a mac pro but have to use a windows based software or some time...

PLEASE make your title a little more helpful in future - that is, if you want replies. It's Saturday and a long weekend - you need to catch the eye of someone who might be able to help you. With your original title most folk are going to skim right over it. My edit probably isn't perfect either but at least it shows that you are not looking for folk to join your band, a shop which stocks sledgehammers or asking whether any shops will be open on 1st August as you forgot to buy milk this morning.

You can get software for your Mac Pro so that it can run windows. What software do you need to use ? Do you need to be able to transfer files to someone else in the same software ? Or log in to something ?

Maybe there is an equivalent software in Mac...

What version of windows do you need ? My experience is that the various versions are notoriously uncompatible, so if it's a work or study-based solution I recommend getting the exact specifications to match what is being used for the work/study situation.
