Woot! As I'm sure you've seen by now, it takes a few minutes to do that initial header sync and then the blocks start flying down.

That being said, I'm not a huge fan of the Bitcoin Core gui. At least on mac/Windows, afaik it doesn't install bitcoind as a daemon (background service that always runs) so your node is only up and staying in sync when the gui is up. For some use cases that's fine. But won't work if you also want to run things like mempool.space.
