Apple släppte för några dagar sen Thunderbolt Software Update 1.2.1 som fixar en trist bugg i 1.2.
Lösningen är att ominstallera Lion eller OS X Lion 10.7.4 Combo Update. Ingen data förloras, installationen sker ovanpå det befintliga systemet. Men en hel del extra jobb.
“Apple has identified an issue with Thunderbolt Update 1.2 (released Monday, June 11th, 2012) which caused some Macs to become unresponsive on startup after the update was installed. Apple promptly withdrew the update and investigated, discovering an installation compatibility issue with a previous Thunderbolt update applied by some customers. Apple apologizes for the disruption this caused for customers with affected Macs.“
