How to save text messages to your computer
Short answer. On a Mac, turn on Messages in iCloud so your conversations appear in Messages, or back up the iPhone to the Mac in Finder. A backup keeps messages safe but you can't open and read it. For files you can open, print or send, export the conversation to PDF or CSV.
1. Messages in iCloud (Mac)
Turn on Messages in iCloud on the iPhone (Settings, your name, iCloud) and on the Mac (Messages, Settings, iMessage). Your conversations then appear in Messages on the Mac and stay in sync.
That's handy for reading, but it's a mirror, not a copy: delete a message on the phone and it disappears from the Mac too.
2. A local backup of the iPhone
Connect the iPhone with a cable, select it in the Finder sidebar, and click Back Up Now. On Windows, the Apple Devices app (or iTunes) does the same.
The backup holds the Messages database stored on the iPhone, and it stays put even if you delete messages on the phone later. With Messages in iCloud on, Apple says messages synced to iCloud are left out of computer backups, and older messages or photos may be kept only in iCloud, so check that a copy holds the dates you need. The messages are stored inside the backup as a database, so you can't open them, and restoring the backup replaces what's on the phone.
3. Export to files you can open
An exporter turns the messages into ordinary files: a PDF to read, print or send, and a CSV spreadsheet. Message Mammoth reads either Messages on your Mac (ready in seconds) or your iPhone over a cable (usually 3 to 15 minutes for messages only on a phone without backup encryption, or 15 to 50 minutes when the whole backup is copied, with progress shown). Everything stays on your Mac; nothing is uploaded. The app shows the dates each conversation covers before you export.
It's free to preview every message and to try exports of up to 20 messages in total, calls and group events included. Unlimited exports are $29.99 once.
