I have Snow Leopard and needed to install an update, the SMC v1.5 update.
I downloaded it and installed it, appeared to install without error. I went to see if the update had been installed and it said it had been installed yet it also said I had 1 update, SMC v1.5 to install!
I did the update again and it installed, now no more updates are showing but looking in the list of installed updates, there are several installs of one update on many days like a Thunderbolt update 1.3 installed 4 times!
Am I missing something here, like minor version numbers, 1.5.0 and 1.5.1 or is something going wrong ... anyone else come across this before?
