I would like to know if Xcode runs on an external hard drive. I currently don't have a usable mac and won't be getting one for another several months, but my university has several Mac labs. Unfortunately, they're tied down to the point where we have very limited user access and hard drive space. So the main points are: - Will Xcode run on an external drive? - Does it require administer access to certain Mac OS X system folders? (i.e. Placing files in system folders I won't have write access to) - How big is the install? (Can I use a flash drive?) - Anything else I'd have to worry about? A not so important question, since I can always create partitions, but... Can I run Mac applications on FAT32/NTFS formatted drives? I constantly jump between Windows and Mac systems for work and availability reasons. I'd really like to get into Mac programming, even though I don't have a Mac of my own right now. Hopefully someone can point me to the right direction.
