As stated, when trying to do a fresh installation of Mac OS X Lion for a client, the install process either hangs at 33 minutes remaining with a beachball (with a hard drive installed internally), or installs fairly regularly when the hard drive is mounted externally, but produces the "Mac OS X Installer could not download additional components" error. (Naturally, I would do an upgrade installation if possible - I received the MacBook from the client with no hard drive at all, and a Western Digital Scorpio Black 500 GB drive was suggested as a replacement drive.) I've noticed some other strange things about then notebook - particularly, when reading the install DVD for Lion (or for OS X Leopard), I have to wait a VERY long time for the boot screen after pressing Option at POST. I'm not sure if these things are related, but it's certainly made the effort of checking/formatting the HDD via disk utility very arduous (incidentally, the disk has been checked, verified, and formatted under a GUID partition table several times). Any thoughts on what can be done to get this MacBook up and running again? The most I know as far as specs are concerned is that it's a Late 2008, Aluminum Unibody Macbook 5,1 (A1278), with a 2.4 GHz Core2Duo Processor (as stated by my client).
