Most Mac updates go fine. But every so often a new release crashes on launch, drops a feature you depend on, or breaks compatibility with a file or plugin. If the update replaced the old app in place, getting back to the working version can be surprisingly hard. A quick backup beforehand turns a bad afternoon into a thirty-second rollback.
When a backup actually matters
You rarely need this for App Store apps — you can re-download previous purchases through your Apple Account — or for most vendor-managed updaters that keep their own rollback paths. It matters most for direct-download updates, where a new DMG or ZIP overwrites the app in /Applications and the old build is simply gone.
Option 1: Make a manual copy
- Quit the app you are about to update.
- In Finder, open your Applications folder.
- Select the app, press ⌘C, then paste a copy somewhere safe (an external drive or a
~/App Backupsfolder). - If the new version misbehaves, delete it and move your copy back into Applications.
Simple and reliable. The downside is that it is easy to forget in the moment, and copies pile up without versioning.
Option 2: Time Machine
If Time Machine is running, you already have historical copies of your Applications folder. To restore, open the app's folder in Finder, enter Time Machine, step back to a date before the update, and restore the older app bundle. This works well but depends on having a recent backup from before you updated.
Option 3: Automatic, per-app backups
The most reliable approach is to back up automatically as part of the update itself, so it never depends on remembering. macCurrent can create a path-aware backup of an eligible app immediately before a direct replacement update, keep a configurable number of backups per app (up to three per app identity), and restore from the app's context menu. Backup readiness, update history, and restore activity stay attached to the specific app you are reviewing.
