Hi.
A fellow composer has just told me about this. I installed the faulty update last week.
A Mac repair man earlier today spent two hours at my studio trying to mend my computer. He had never come across a problem like it. The only way the internet could be accessed was through Chrome - Mail, Safari, iTunes, App Store, etc. wouldn't connect - and my main Mac Pro wasn't being seen as a shared computer by the other Macs on my network.
£210 his time cost me. He left without having fixed it and, on his advice, I am now in the process of a clean install.
I have to admit that I really am not very happy at all.
VSL, can I please ask: why didn't you email everyone to inform them that this update was buggy? If you had have done, I would have been aware that the fault lay with your update and I wouldn't have needed to get anyone out to try to fix my computer. If you'd like to reimburse me the £210, I'll happily forward you macman.co.uk's invoice.
Nick
