Apple is using its ability to automatically update Mac computers to fix a big security vulnerability that allowed hackers easy access to computers running the latest version of MacOS. It's only the second time Apple has made use of the ability to push down an update to all computers.

"Security is a top priority for every Apple product, and regrettably we stumbled with this release of macOS," Apple said in a statement.

Why it matters: The security hole was huge, but Apple moved quite quickly to patch things and forcing an automatic update ensures that machines won't remain vulnerable.

Apple said it began working on an update as soon as it became aware of the issue. The update was made available this morning and later today will be automatically installed on all machines.

"We greatly regret this error and we apologize to all Mac users, both for releasing with this vulnerability and for the concern it has caused," Apple said. "Our customers deserve better. We are auditing our development processes to help prevent this from happening again."

Our make-believe economy is here to stay

The Federal Reserve and global central banks are remaking the world's economy in an effort to save it, but have created something of a monster.

Why it matters: The Fed-driven economy relies on the creation of trillions of dollars — literally out of thin air — that are used to purchase bonds and push money into a pandemic-ravaged economy that has long been dependent on free cash and is only growing more addicted.

Attorney General Barr may be fired or resign, as President Trump seethes about Barr's statement this week that no widespread voter fraud has been found.

Behind the scenes: A source familiar with the president's thinking tells Axios that Trump remains frustrated with what he sees as the lack of a vigorous investigation into his election conspiracy theories.

Director of National Intelligence John Ratcliffe on Thursday will publicly warn that China's threat to the U.S. is a defining issue of our time, a senior administration official tells Axios.

Why it matters: It's exceedingly rare for the head of the U.S. intelligence community to make public accusations about a rival power.
