Apple today announced in an updated support document that the Back to My Mac service is being eliminated from all versions of macOS on July 1, 2019.
Apple previously warned that Back to My Mac support would be eliminated in macOS Mojave, but the updated wording seems to suggest the feature will be removed from all versions of macOS rather than just macOS Mojave.
As of July 1, 2019, Back to My Mac service is not available in any other version of macOS. You can use these alternatives for file access, screen sharing, and remote desktop access.
macOS Mojave has not had the Back to My Mac feature since the first developer beta launched, and Apple confirmed plans to end support for the feature in August 2018.
Back to My Mac is designed to let Mac owners connect to one Mac from another Mac for file transfers and screen sharing purposes. It lets users create a network of Mac computers with two or more Macs, but it can be complicated to set up and use, which is perhaps why Apple has decided to discontinue it.
In the support document, Apple suggests customers can access their files across all of their devices - including new machines - from iCloud Drive. Other Macs can be operated through screen sharing functionality, and Macs can be managed remotely with Apple Remote Desktop, software available from the Mac App Store for $80.
Some Back to My Mac users are sure to be unhappy with Apple's decision to sunset the feature entirely and the suggestion that users transition to Apple Remote Desktop for remote management purposes given its high price tag, but there are third-party options like TeamViewer and LogMeIn.
