Not sure if this is the rights forum but given I have just updated my MacBook Pro and this is the operating system now I thought I would ask. On my 2015 MacBook I used to use multiple pop gmail accounts with Mac mail and on my iPhone. During the day I would delete messages on my phone and at night open my computer, download all messages and file and delete how I pleased. I like to keep very few emails on my phone so could delete them with pop and still have back up copies on my computer. I can’t do that with imap as everything always syncs! Great for most. Not for me. So to the question. I need to know how I can create folders on my MacBook so I can save and file emails I want to keep on an offline basis. Is this possible? Anyone got a good way to set this up? Please let me know do you can. Thanks.
