I'm considering updating to the latest mac, more precisely the : 2.5GHz Quad-core Intl Core i5, 500GB HD, AMD Radeon HD 6750M with 512MB, recently released. I've seen some have been having problems with macs and so i'm having second thoughts now. So could anyone who has aquired this model or higher please let me know how it is behaving for them, not neccessarily using V2 as i will certainly be using a TPV.
