Apple Seeds Third Beta of macOS Monterey 12.4 to Developers [Update: Public Beta Available]

Apple today seeded the third beta of an upcoming macOS Monterey 12.4 update to developers for testing purposes, with the new update coming a week after the release of the second macOS Monterey 12.4 beta.

macOS Monterey 2
Registered developers can download the beta through the Apple Developer Center and after the appropriate profile is installed, betas will be available through the Software Update mechanism in System Preferences.

According to Apple's release notes, Universal Control in the new iPadOS 15.5 and macOS Monterey 12.4 updates is not compatible with machines running macOS 12.3 or iPadOS 15.4, so Apple suggests that as a workaround, users should update their ‌Universal Control‌ devices to the new betas.

We don't yet know if there are any other features in macOS Monterey 12.4, and nothing new was discovered in the first two betas.

The last letter of the build number, which is letter e, is same with pervious two beta.
Does this mean that the official version is still far from us?
Typically with .4 releases, Apple tends to do between 5-6 betas, so as we are on the third, I'd say we have at least 3 weeks before it gets released to the public; just in my opinion, though, Apple could release it later or sooner.
