LuLu is the best choice, nowadays.
It's given for free and it doesn't force you to pay for it (but it's worth spending a dollar or two on Patreon, as gratitude).
Has a simple GUI.
Allows to blocks the outgoing connections (for the incoming is better to use Apple firewall or something else)
Allows to choose the apps that should be allowed ...
I had this same problem. I installed 10.6.3 on an old iMac late 2006 a1207 which can only go up to 10.7.5 Lion.
After installing Snow Leopard 10.6.3 with the disk I was unable to update the software through the updater in OS X. I would get stuck during restart with only a mouse. Also, once I did manage to update to 10.6.8 (where the App Store comes ...
Here is a tweak that you can try:
Go to Finder -> Applications
Move Xcode.app to trash. (Here it will ask you if you want to cancel update).
Agree to cancel the update.
Go to Trash -> Xcode.app, right-click and click on "Put Back"
Re-start using Xcode and continue with your work.
Also, while you wait for XCode to update and you are in a slow internet ...
Check the "purgeable" space of your APFS disk with Disk Utilities. It seems Finder count this space in free space, but not App Store.
But you can trick macOS to clean up APFS by creating a huge garbage file, then deleting it.
You can create a huge file that will force macOS to clean purgeable files to free you space. In order to do so, type this command in ...
I don't think there is a definitive answer, because it's likely to depend on the specific Mac & how the data aligns to sector sizes when written. You'd see the same thing if you wrote a 1GB movie file & 1GB of small text files to a drive. The byte count may be the same, but the space used on disk would not.
If you look at the three basic ways to see ...
There's really no easy way to produce a definite answer for you. The definite answer varies from system to system.
You could get the definitive answer by freeing a small amount of disk space. Taking a full backup of your system. Try installing. When it fails, restore from backup. Repeat until you have the definitive answer.
It would be an unrealistic ...
You might be close, but I downloaded from the developer website and I had freed ~22 GB.
Try freeing up some more, like cache or movies you have watched, or software you don't use.
How can I figure out what's slowly eating my HD space?
Reduce size of the Xcode application

The Mac in question does not support a new enough macOS to install the latest versions of Xcode required to build an app that can on the App Store.
However, you could use an online build service in order to be able to develop and test apps on this Mac. For example you could use your Cordova project with Monaca - they have a free plan where you can do 2 ...
Is there any way to develop iOS apps on a MacPro 2,1 in 2019?
No. I'm afraid you've bought yourself a boat anchor. Developing iOS applications requires you to run a current version of XCode, which in turn requires a current version of macOS.
The MacPro2,1 was produced between mid-2007 and early 2008; the processor in this machine does not support some ...
