How to Install macOS Mojave 10.14.5 Beta 3 on Mac

If you are like us, you would want to install macOS Mojave 10.14.5 beta 3 on your Mac to dig into the new features. Follow this complete guide to get started with the latest macOS Mojave beta!

After months of beta testing, you may have updated macOS Mojave beta to the final version for stable and improved performance. Though many of you would be pretty happy to stay with the official release, the loyal beta testers wouldn’t be done as yet. If you had tried your hands on the previous Mojave beta, installing macOS Mojave 10.14.5 beta 3 would be a pretty simple affair.

However, if you are new to beta testing, you will have to start afresh. As always, ensure that you have fully backed up your Mac to remain on the safer side of the stream in case of any mishap. Besides, you must be prepared to encounter some unexpected issues (as bugs are part and parcel of the pre-release software). If you don’t want your daily driver to get affected, we recommend you install the beta on your secondary device (if you have the option).
