Apple has seeded the fifth beta of macOS Mojave 10.14.4 to both developer testers as well as those registered in the Apple Beta Program. The new build is 18E215a for those keeping score at home. It comes roughly a week after the fourth beta was released. If you have a Mac registered in the program, you can get this update through the Software Update feature found in Settings in Mojave.
macOS Mojave 10.14.4 is mostly focused on bug fixes, security updates, and performance improvements, there are some new features coming with the release. Apple News will be available to those in Canada for the first time with this release. Canadians will be able to read articles in both English and French. Touch ID support has been expanded in Safari in 10.14.4 so you can now use it to autofill browser fields.
Apple has not confirmed a release date for this update to macOS but it shouldn’t be much longer. Apple usually has four to five beta builds for these types of “dot” releases. Given most are expecting 10.14.4 before the end of this month, it is possible that this fifth beta will be the last.
Average Apple Guy, and Apple themselves, does not recommend installing beta OS builds on your production Macs. Any bugs in the code could cause degraded performance or data loss. It always best to install beta builds on non-product devices.
