Step-by-Step Gantt Chart Tutorial for Making a Gantt Chart in Excel 2016 on Mac OS

MacOS isn’t known for things like accounting or project management. The Mac platform has become more synonymous with video editing, graphic design, audio and other creative work.
However, we’re starting to see more of a shift in Mac usage, a blend in the office that was once predominantly a Windows-based environment..

We all love Microsoft Excel and we use it almost every day for everything – from a simple calculator to tracking massive projects.
For this reason, we created Gantt Excel, an automated excel template that allows you to create professional-looking Gantt Charts all within Microsoft Excel in Mac OS.

Click the Ok button when done. A new Gantt Chart is automatically created for you.


Gantt charts don’t give useful information unless they include all of the tasks/ milestones needed for a project to be completed.
So, to start, list all of the activities as tasks. There are three ways to add tasks in Gantt Chart Excel

Method 1Type directly in the excel grid. If you type a task where it says “Type here to add a new task“, it will automatically create a new task with default start and end dates and the timeline will instantly update.

Method 2Click the Add Task button on the Gantt tab

The task details form will open up where you can enter all the task details including task resource, estimated, baseline, actual – start and end dates. You can also keep track of costs including estimated, baseline and actual costs, therefore making it an excellent budget and costs planner.
Task notes can also be captured to include a short description of the task to clarify its purpose or scope and to provide additional info to everyone involved.

Click the Ok button when done. The newly added task will show up in the excel grid with all the details.

Go ahead and add a few tasks as in the example below and set the start and finish dates.

Importantly, note that the Work Break Structure (WBS) is automatically calculated and set for you.


If a task is relatively large and requires several users with different skills to manage, break the task into subtasks and create parent-child relationships.

To set parent-child relationships, select a task that you want to convert to a child task and click on the Make Child button.

Shortcut – Alt + Right arrow key

To create a parent task from a child task click on the Make Parent button.

Shortcut – Alt + Left arrow key

As a result, when you group child tasks together under a parent, values such as dates, costs etc. aggregate and roll up to the parent task.

This is how the tasks look when I set a few tasks as child tasks.

Milestones help your team stay on track and to more accurately determine whether or not your project is on schedule.

To add a milestone click on the Add Milestone button on the Gantt tab.

This will bring up the Add Milestone details window. Enter the milestone details and click the Ok button when done.
To illustrate, see the example below. The milestone and a diamond-shaped symbol show up in the timeline.

Equally important, is to set up the Gantt chart correctly. Let’s look at all the settings screens and go through them one by one.
Click on the Settings icon on the Gantt tab.

Display Settings
By default, the Display tab opens up first. Here you can set the general theme colors including the different timeline bar and milestone colors.
You can also choose to show additional timeline bars for baseline, actual dates and the overdue bar for all overdue tasks.

Lastly, one of the most sought out features is to show text within the Gantt Bars. You can check the Enable Text Display option and select any text from any column to show within the Gantt bars.

This is how it looks when the Show Text in Gantt Bars is enabled. We think it is one of the finest features of Gantt Chart Excel.

Calendar Settings
The calendar tab is where you can select Workdays. You can also select the way the week numbers are calculated by either using Excel’s week calculation or use the ISO week calculation.

If you want to see more of the timeline then you can increase the number of columns in each view and set the column width for each view as well.

Other Settings
Switch over to the Others tab to set Currency symbol and Date format.
Additionally, you can define how Percentage complete is calculated for the tasks. You can use the Manual or Automatic mode for entry and use Simple or Weighted calculation for the Parent task roll-up calculation.

Columns Settings
Finally, we have the columns tab where you can hide or unhide existing columns. In like manner, you can also insert up to ten custom columns or delete them if required.

In Conclusion, the beauty of Gantt Chart Excel is we have six calendar views to choose from namely Daily, Weekly, Monthly, Quarterly, Half-Yearly and Yearly View.

From here you can easily customize the Gantt chart by changing timeline colors, and adding various details like percent complete, costs etc…  As shown below, with some tweaks you can create a timeline that’s sure to impress.
