Some Mac owners trying to upgrade to the latest edition of macOS are encountering errors.
Users across countries are receiving the message “An error occurred installing macOS,” or cryptic references to bridgeOS, the altered version of watchOS used to handle Mac’s proprietary system like that of the Touch Bar.
There has been no similar solution for everyone’s problem on this error.
Though some people managed to get their way out of the issue by resetting their Mac’s system management controller, or SMC.
Even then, users reported encountering some glitches and strange errors.

Process is being prevented by the errors, according to complaints on Apple’s support forums.
A common factor which appears in all these cases is, Apple’s T2 chip, so far found only in the iMac Pro and 2018 MacBook Pro. This not only runs the SMC, Touch Bar, and Touch ID, but incorporates an image signal processor and controllers for audio and mass storage.
Few users on Apple’s community-led support forums have reportedly had confirmation from Apple about the T2 chip behind the cause of the problems, which indicates the company would produce a software fix for the issue in the near future.
Apple is not as much help for the limited users suffering the issue
Even though the issue seems to be a big one, Apple has provided no insight on even help on the matter at all. Users across places, have not been able to reproduce the problem locally but did contact several service providers about the issue for help.
According to the providers contacted, users looking forward to upgrading to Mojave should back up data in total using Time Machine, then proceed to install Mojave. If the installation fails, users should boot to the restore partition, by holding down Command-R on startup.

Following the boot to the restore partition, users should format the drive using Disk Utility prior to installation, and connect to a wired network (LAN/Ethernet) to install the Mojave system update rather than connecting to Wi-Fi. Following successful installation, data can be moved to the volume using the Migration Assistant in the Utilities folder.
