Per this notice on Apple’s website on June 20th, Apple announced a voluntary recall of a limited number of older generation 15-inch MacBook Pro units which contain a battery that may overheat and pose a safety risk. The units were sold primarily between September 2015 and February 2017 and can be identified by their product serial number. The recall does not affect any other 15-inch MacBook Pro units or other Mac notebooks.
This article details that users who have MacBook Pros that were manufactured should check to see if their computer is involved. Instructions are given on how to check for this in the linked website above. This is vitally important due to the potential safety hazard involved with affected computers.
Please let us know if you have any questions or would like to discuss further.
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.

Individuals that rely heavily on WiFi may want to hold off on new equipment purchases until they are WiFi 6 (aka 802.11ax) equipped and/or upgradable to WiFi 6. As detailed in this article, the new upgrade will make WiFi faster, while also approving its efficiency in other areas. The speed is almost tripled from WiFi 5 (aka 802.11ac), meaning that it can deliver more speed to more devices. And with its efficiency improvements, the advantages are more apparent through improving the network when lots of devices are connected.
WiFi 6 puts forth new technologies to help mitigate the issues that come with putting dozens of Wi-Fi devices on a single network. It allows routers to communicate with more devices at once, send data to multiple devices in the same broadcast, and lets Wi-Fi devices schedule check-ins with the router. When all is said and done, the result should be that the devices are more likely to maintain top speeds even in busier environments.
In addition to speed improvements, WiFi 6 should provide greater security, as WiFi 6 will need to support WPA3 to receive certification from the Wi-Fi Alliance. WPA3 is the most recent security protocol and the biggest upgrade to the security level of WiFi in a decade. This will make it harder for hackers to crack passwords by guessing multiple times, and make some data less useful even if hackers are able to gain access. Therefore, most devices will include this greater level of security to receive certification.
In order to use WiFi 6, you’ll need a router that supports it. Those that will see the biggest improvements in WiFi performance are those that have WiFi 6 enabled devices and have lots of devices attempting to connect to one WiFi 6 router. At this point, the routers remain relatively expensive, but should become more affordable as time goes on.
