The UDID or Unique Device Identifier is a unique serial number for your Mac and differentiates your Mac from all the other Macs in the world. It, therefore, is an important Apple serial number, just like with any other Apple product.

It is not always that users look for UDID. However, the importance of UDID was realized when the app developers started sharing the UDIDs of the users with advertisers. The UDID displays the profile of the users to the ad company easily.

Your Mac, just like iPad , iPhone and Apple Watch , has a UDID, which is technically called the Hardware UUID. Developers can use this UDID for sending app builds to you before they are available publicly. Fortunately, it is very easy to find the UDID if you know where you should look for it. Once you find the UDID, you just need to copy-paste it and mail it to the developer to get the ad-hoc app for beta testing.

So let us see how to find UDID of a Mac or Macbook easily.

How to Find UDID of a Mac on OSX :

Point your mouse to the Apple Logo in your Mac and click it. You will see a drop-down menu.
Next, click the option labelled as About This Mac.
It will open up a windows with two options, namely Software Update and System Report.
Click the System Report option.
Now click on Hardware. You will find your Hardware UUID under the Hardware Overview section.

That’s it. The Hardware UUID is nothing but the UDID of your Mac. As said before, the Mac App Store is not the only way for distributing software on Mac. The developers can send you a regular app which is a non-Mac App Store app. Many developers send the users betas of their apps for beta testing before releasing it on the Mac App Store. In such cases, UDID can be very useful.

However, many developers have evidently been sharing UDID of users with different ad companies, causing the profile of users to get compromised. This has forced Apple to take strict measures towards the third-party app developers. Apple sends ultimatums to such developers telling them to stop sharing the UDIDs and if they fail to do so, their apps will be removed from the App Store.
