I found an old iMac (21.5", mid 2010, i3 3.06 GHz, Mavericks OS X 10.9) perfectly working and almost unused.
I intend to upgrade the memory from 4GB to 16 GB and to replace the old 5400 rpm HDD with a SSD (I know, transfers speed will be limited by SATA 1 interface).
What are my...
I updated my Gigabyte Z87X-OC BIOS to F8 and now I cannot boot Mavericks from USB. Tried 3 different USBs in all the possible USB ports with the same bad result. The message is "Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press any key".
What is strange...
I tried a lot of settings (MultiBeast 6.0.1) with no success.
Could you please help me?
