Apple have just released their update for the MacBook Air (Mid 2013 models) to fix a couple of issues that have been annoying some users. The first is the flickering that is being experienced whilst using Adobe Photoshop which started to be reported soon after release.
The second issue is around the Macbook Air losing WiFi connectivity possibly due to a driver glitch with the new 802.11ac cards they now use.
Apple today released an update for the Mid–2013 MacBook Air to fix both an issue that caused some users to experience severe flickering when using Adobe Photoshop and a bug that caused some users’ Wi-Fi to intermittently disconnect.
This update is recommended for MacBook Air (mid 2013) models.
