New Apple update against Intel CPU attacks imposes 40% performance penalty

Intel processor

As mentioned in this article, Apple has posted a new article on its website that details how a user can implement Full Mitigation for a “theoretical” speculative attack that targets Intel CPUs (central processing units). Full Mitigation is mostly for users that are at heightened risk for an attack, such as government workers or high-ranking business executives.

Enabling this mitigation results in an approximate 40% drop in performance. However, as previously mentioned, most users won’t need to enable this level of mitigation, as the attack is theoretical at this point and there are no known attacks in the wild for this.

macOS 10.14.5 includes the most relevant patches for users, although there have been reported issues from Mac users with some methods of file sharing over macOS. As always, it is the best practice to only download trusted software from the Apple App Store.

Mail users reporting issues with Gmail after macOS update

As noted on a number of complaints across Apple related sites, the newest update of macOS (10.14.4), which was released a few days ago, causes issues with authentication when attempting to sign into a user’s Gmail account. Users are reporting receiving an endless loop, bouncing between macOS and Google’s sign-in page in Safari.

Because of this, it is recommended not to upgrade to OS 10.14.4 if you use Gmail within your Mail application until Apple releases an update and it’s verified as a fix for the issue.

It appears this is a verified issue per discussions on the Apple Support site. Attempting to use a different browser such as Chrome does not succeed as a work-around, as the Mail application interacts directly with Safari in this process.

Apple Mail can also exhibit other intermittent issues for some users, such as not showing a message as replied-to where a user had just replied. If you are noticing any odd issues such as this, restart your Mail application.

Hackers use malicious Windows file to access MacOS

Hackers are utilizing the file type “.exe” to unload malicious software onto MacOS powered computers. As the article linked below mentions, by default, .exe files won’t run on a Mac. The malicious download worked around this limitation by bundling the .exe file with a free framework known as Mono. Mono allows Windows executables to run on MacOS, Android, and a variety of other operating systems.

Users should be cautious of downloading any software from insecure resources such as Torrent sites. Torrent sites provide users with the ability to download any type of software, movies, games, etc, which leads to a “Wild West” scenario, where all bets are off with the type of files that you’re actually downloading.

It’s also wise to ensure children are not accessing these sites either, and to block access to Torrent resources on company networks.
