SQLite is a compact, cross platform, self-contained relational database management system that is available in the public domain. SQLite is included in macOS and Mac OS X by default. It is located in the /usr/bin directory and called sqlite3.

Using SQLite, users can create file-based databases that can be transported across machines, platforms, etc. The only thing needed to then view or edit these databases is the SQLite command line program, or another tool capable of communicating with SQLite.

SQLite databases can be created by using the sqlite3 program in /usr/bin. To get to this program, you can open up a terminal window (Applications -> Utilities -> Terminal) and then type the following followed by the enter / return key to change your directory to the /usr/bin location:

Part 2: Troubleshooting on Opening and Reading PDFs in macOS

Many people experience problems when trying to open or read PDFs on Mac. This is due to a variety of reasons, but luckily this problem is usually quite an easy one to solve in just a matter of minutes. Here are the three main reasons why you may have a problem reading a PDF on Mac and what you can do to solve the problem.

Question 1. Your Web Browser needs Updating

Solution: This is one of the most common problems that can prevent you from being able to read a PDF. Not all browsers update automatically, and it could be that yours needs a manual update. You can usually run a regular software update, but other times you may be required to update manually through the menu. An outdated browser may be the issue, in which case you may need to update your browser to resolve the issue. You can then make annotations and markups within your document.

Question 2. Your Browser is not Compatible

Solution: This issue depends on your operating system. If you are running OS 10.5 x, as many are, you will find that the later versions of Safari, for example, are non-compatible with your operating system. This will lead to you being unable to open PDFs and a number of other problems. It is recommended that users with this operating system try using Firefox instead to solve the problem.

Question 3. Check the Adobe Reader Plug-in

Solution: This problem also affects many users. If you are opening your PDF with Adobe Reader, the Adobe Reader Plug-in can be problematic, especially if it is an automatic launch when you enter your browser. The trick is to delete the plug-in (just the plug-in, not Adobe Reader itself). Try using Adobe Reader as a stand-alone program rather than having it run within your browser, and the problem should be solved. You can also re-install the plug-in if necessary.
