The new MacBook Air sometimes loses connectivity after a few minutes even though the signal shows full strength and other devices remain connected. In some cases it may happen multiple times per day with the only resolution being a reboot or in rarer cases changing the Wi-Fi channel.
If you have a new MacBook Air and you’re having intermittent Wi-Fi connectivity problems or occasional screen flicker when using Adobe Photoshop, then you should install the 3.35MB software update Apple just released for download.
Apple posted the Wi-Fi update two days ago to address the hundreds of complaints that saturated the support community.
The update is applicable to Mac OS X 10.8.4 build version 12E3067. It also addresses a problem where the volume sporadically fluctuates during video playback.
Have you had this problem with your Mac? Did you encounter any surprises when installing the update? Let me know in the comments.
