You can work on the same Publish post from two Macs, for example if a virtual assistant builds your posts and you review them before they go live on your website. Each Mac needs its own copy of the post's photos.
What does the second Mac need?
To open a post on a second Mac, that Mac needs a copy of the same photos, with the same file names. They can be in a folder on the Mac, or on a drive you plug into it, like an SSD (solid-state drive).
If you're working with a virtual assistant, sharing the photos through a Dropbox or Google Drive folder works well.
How do I open a post on a second Mac?
To open a post on a second Mac, follow these steps.
Copy the post's photos to the second Mac, or plug in the drive that has them. Keep the same file names.
Sign in to Publish on the second Mac with the same account.
Open the post. Publish shows that the post's source folder isn't found on this Mac.
Click SELECT SOURCE FOLDER and choose the folder with the same photos.
Publish matches the photos by their file names and loads the work done on the other Mac.
