Update to #100686

Hello Larry,

Thank you for clarifying.

You do not need to install TheBrain 15 on your desktop if you prefer not to. Since your iPhone is already running TheBrain 15, you should be able to turn off Light Sync Attachments from there instead.

Please try this on the iPhone:

• Open TheBrain on the iPhone

• Open the affected Brain

• Rotate the phone to landscape orientation

• Open the menu

• Go to Settings

• Go to Brain

• Go to Sync

• Turn off Light Sync Attachments

• Allow the Brain to finish syncing

After that, please return to the affected Mac running TheBrain 14 and try opening the Brain again.

The reason this can affect one computer but not the others is that each device can have a different local sync state. If Light Sync Attachments was enabled from TheBrain 15 mobile, TheBrain 15 can support that setting, but one TheBrain 14 desktop copy may still run into trouble depending on what it has locally cached or synced.

If the Brain still will not open after disabling Light Sync Attachments from the iPhone and letting it sync, please send a fresh Output.log from the affected Mac right after the failed open attempt.

Best regards,

John
