Ok so i tried to download lion but i failed so i took my MacBook to the Apple Store and he put SL back on but now when i launch disk utilities it says my Macs Harddrive capacity is 159 but only 16 gb avaible and 15 gb used?? How can i fix this without going back to the Apple store(its far) and i dont have the restore disc. Is it because lions install files are still on here?
