Apple Addresses MacBook Air Bugs With OS X 10.9.4 and SMC Firmware Updates

T-GAAP’s E. Werner Reschke notes that OS X Mavericks had brought with it some lingering and annoying issues for Mac Book Air owners.

Alert sounds would stop working a few days after a fresh reboot, and restoring a WiFi connection on wake up could be maddeningly slow, the latter sometimes requiring one to turn off and re-activate Airport in order to get it to connect Waking up from sleep could also be problematic on some machines.

Indeed, my own now six month old 13-inch Haswell MacBook Air manifested the first two of these issues, although aside from the WiFi problem, wake-up has been reliable.

Reshke observes that with Apple’s recent MacBook Air SMC & EFI Firmware updates addressed the alert sound bugs, and Monday’s Mac OS X Mavericks 10.9.4 update makes the WiFi connection and waking from sleep problems things of the past.

At least let’s hope so. I downloaded the last two SMC Firmware updates and Mavericks 10.9.4 Monday a process which took three hours to complete. All,seems to have gone well, and I’ll be interested to see if the bugs have been truly squashed.
