Hi I have a mac unibody 7.1 with lates osx version,16gb ram installed upgrading to kingstone v400 ssd 120gb sata 3 internal, I formatted the ssd as per instructions GUiD, partition 1, extended journal, erased all via mac disk utility (tried it on 2Macs many times) and Sata cable, The new ssd is recognized externally via sata cable and I can transfer files.. After installing it inside I tried to restart with commad R or command R option, I get to a flashing folder logo with ? mark.... I can't proceed to download the new system over the net (preferred). Installing the old hdd externally via sata cable it will restart normally...very slow btw...(reason for upgrading) using disk utility I can see and re format the new ssd while installed inside.. I need to solve this issue and download a new operating system...from scratch Any help ? Thanks in advance !! Cheers!
