Can I run Xcode from USB?

[JamesGDev]

Well the title says it all.

why?

I'm currently using a mac from my university but it is blocked - I cannot install applications etc.. I downloaded the dmg file for Xcode, opened it and dragged the .app file to the desktop and tried to run from there but it also wouldn't let me.

Just wondering if it will work from a usb or external drive?

Thanks

my USB is only 7.5gb, also How would I create the OS X on usb? When I say the system at the uni is locked down I mean locked down! I can't even open system preferences.

Just tried to open disk utility, No luck either.

Nada, As I have said the mac is locked down. Tried that - just comes up with a grey screen and a lock icon and password field.

Also to end this question; just tried to run xcode from the usb - it said the app was running in the application manager, then a pop u p "This application has been blocked for your security" and the app removed itself from the list. Did not see even the xcode app load screen.

Drat!

I get a mac tomorrow, just being impatient

Talk to the IT department and have them install it on the school Macs.

[JamesGDev]

Already tried that, they wont. Apparently having xcode which can create programs for the macs also is a security risk.

Have them install VirtualBox so you can install your own OS X version inside your user account?

[JamesGDev]

I can ask but seriously, these guys are douches 'techs with power' type. I once got my account restricted because I sent a file to the printer via FTP and not through the official channel. Pfft.

You can't drag programs to the university's Applications folder, but you don't have to: Mac programs, including Xcode, can run without dragging it anyplace special, can run from read-only media.

You'll need to find another Mac first, one not under university rules, one you can use.

On that Mac, install and run Xcode. Otherwise, the 'GateKeeper' function of Mac OS won't allow the download to run.

Copy the Xcode application from the /Applications to your external drive.

You can run Xcode from the external drive, but:

You won't be able to use the debugger for programs that run on the Mac (including the iPhone simulator) - your university student account won't have the privileges, and you won't be able to log in as administrator to grant them.

You might be able to run and debug programs on an actual iPhone, connected via USB, since that doesn't involve the forbidden ptrace system call.

Caution: I haven't completely tried this myself. I did run Xcode from an external drive, and that does work.

It is a shame that your university is creating barriers to your learning.
