You may have heard that I don’t do iPhone or iPad development at this time. That said, it’d be silly to not keep track of what Apple is up to with the platform they care for most.
When Apple releases developer beta tools for the mobile platforms, I don’t install the tools on my main Mac hard drive. Instead, I install the tools in a sparse disk image that is completely separate from any other tools. Does it help? I’m not sure since the /Developer folder is self contained as of a few releases ago, but it’s a practice I continue to do out of habit and safety.
Here’s how to do it:
- Open
/Applications/Utilities/Disk Utility.app File -> New -> Blank Disk Image- Set the parameters like so.

The benefit of using a sparse disk image is that it will grow as necessary rather than allocating and taking up a full 8GB or whatever value you set it to.
