I foolisly cliked yes to the upgrade to 5.0. There are multiple problems with this and I dont know why Apple subjects us to them. I cannot waste time with it. The worst problem is with my Linksys wireless router, it now does not work. So no internet support, I am doing this from work! There are other problems too, just read this forum. I re-insatlled 4.9 off a disk but it wont open cause "library is made with newer version"
Please can some-one give me clear instuctions on how to fix this problem, so I can use 4.9 which worked fine with NO PROBLEMS. This is ridiculous. I think this solution must be here somewhere, but cant seem to find it!
Bottom line.....DONT upgrage, it not worth it at all!
