Apple just announced a battery replacement program for certain 13 inch MacBook Pro’s (non touch bar) manufactured between October 2016 and October 2017.

From Apple:

Apple has determined that, in a limited number of 13-inch MacBook Pro (non Touch Bar) units, a component may fail causing the built-in battery to expand. This is not a safety issue and Apple will replace eligible batteries, free of charge. Affected units were manufactured between October 2016 and October 2017 and eligibility is determined by the product serial number.

You can see if your laptop is affected here. All managed services customers of JM Addington and Kairos Dynamic Digital Managed Services have already had their serial numbers run across the the program by JM Addington staff.

We recently came across this error, “A critical software update is required for your Mac.” Attempting to install this update would result in another error, “A critical software update is required for your Mac, but an error was encountered while installing this update.”

Unlike some others on the web we found that simply reinstalling the OS did not resolve the issue. However, booting into safe mode (left shift button while powering on) would work. From there, one can create a Time Machine backup. After we successfully backed up the machine we went into the recovery console (Apple+R on boot), ERASED the “Macintosh HD” partition and then re-installed.

This still prompted for the update but we were able to successfully install it. After a fresh install, Migration Assistant loaded the fresh Time Machine backup back onto the machine.
