Better this came out now than wait a while…
On Friday, Apple released its OS X Supplemental Update 1.0 for its late-2013 iMac lineup. The firmware update, a 17.9 megabyte download, offers the following fixes and changes:
– Fixes an issue that may cause external drives to be ejected after the computer goes to sleep.
– Fixes an issue that may prevent certain USB Bluetooth adapters from working.
The update requires a late-2013 iMac running OS X 10.8.5 or later with NVIDIA GeForce GT 750M graphics to install and run and can also be downloaded and installed via OS X’s Software Update feature.
If you’ve tried the update with your new iMac and have any feedback to offer, please let us know in the comments.
