The first time you download Xcode it downloads the whole thing, about 12GB. When you later upgrade Xcode it only downloads the changes, often about 2GB-4GB. That original 12GB is compressed, so when expanded when being installed, probably needs another 20GB; hence your problem. After installation, the downloaded 12GB file will be removed. There's no real solution other than creating some free space on your disk. If you've used up most of your (guessing) 256GB drive, copy those videos that you don't need to watch everyday to somewhere else. Don't forget that UWA provides 1TB of network storage for each student, using Microsoft's OneDrive: https://www.it.uwa.edu.au/it-help/storage

Would it be sufficient to just install the Xcode Command Line Tools (which is significantly smaller) without the full Xcode application? I'm able to `make` and `cc` with just the former installed.

I don't know, having never installed only command-line tools. Unless you find an answer on the web, you'll just have to try it.

I have also been having this problem on my baby 120GB Mac, but I read on Stackexchange that compiling C programs and performing command-line development does not require the full download of Xcode. So I suppose the answer to this thread depends on if we'll be building programs in Xcode as well or just using it to compile. Could anyone offer any help please? I have minimal knowledge of C but I am led to understand that any old text editor will do as far as code building goes... Thanks

Yes, the space gets tight those 128GB drives, with macOS taking about 15GB and the mystery 'System Data' 30-40GB (https://beebom.com/system-data-mac-storage-delete/). In this unit we won't be requiring the use of Xcode - after all, most students don't have a Mac - and you can certainly complete all the labsheets and projects using just a character-only text editor. I use vi, or vim, for nearly all of my programming, teaching, and staff-admin work, on Macs and Linux, much of which is undertaken across a network. After you've tackled the learning curve, it really pays off to gain familiarity with one editor that is widely available. I haven't tried it recently, but you may be able to squeeze Visual Studio Code onto your Mac: https://code.visualstudio.com/docs/setup/mac

I believe vim is installed on Macs by default, so I'll have a go at getting used to that. Sounds like a much better plan than deleting random system files to try clear up my 40GB of "System" storage...

Yes, vi is installed on new Mac installations (and linked to vim). But there was never a suggestion to delete random system files - that would be quite a dangerous things to do. But there are a number of free, 3rd-party applications which identify old log and cache files, and files once needed for now deleted applications.
