Apple Command Line tools

Few things before you start installing the below listed items on Catalina.

1. SIP needs to be disabled.

2. On unsupported macs like 2008 and 2009 2,1 and 3,1 models you need to use a patcher from dosdue1 in order to be able to install/boot into Catalina. Your best bet is if you use an SSD that is formatted APFS. Anything else will not give you the performance/speed (on these older macs) that is satisfactory.

3. Mojave and earlier os versions come with bash as the default shell. Starting with Catalina, your Mac uses zhs. You can make it a default in System Prefs under Users & Groups.

Install command line tools via terminal and allow third party software installation:

$ xcode-select --install 
$ sudo spctl --master-disable
