Migrating from Windows 10 to macOS Sequoia V15.2
After searching and following some suggestions approaches I've consolidated these into the following steps which worked for me:
Copy the Profile to a Disk/USB
- Mount the disk/USB. This needs to larger than the profile selected
- On W10, open TB -> Troubleshooting Information -> Profiles -> about:profiles.
- Find the the profiles where 'Default Profile' is Yes
- Click on Show in Explorer (e.g. vx7sjwjh.default)
- Close TB
- Copy and paste the folder selected in Explorer to the disk/USB to be used for the transfer.
Install the Profile on the maxOS
- Mount the disk/USB
- In Finder, find the mounted volume and copy the profile
- In Finder, select Go->Home
- If you can't see Library enter 'command+shift+.'
- In Library->Thunderbird->Profiles
- Paste the copied profile
Assign the Profile in TB
- Open TB
- Help->Troubleshooting Information->Profiles->about:profiles
- Create New Profile->Continue
- Choose a name that has not been assigned. You will see an error 'A profile with this name already exists' if it is not unique
- Click on Choose Folder
- Select the folder you pasted
- Click Done
- Scroll down until you see the Profile you created (if you don't see it, restart TB)
- Click on 'Set as default profile'
- Click on 'Launch Profile'
You should now see your profile
