[QUOTE="pigoo3, post: 1346759, member: 56379"] Depends on exactly which model MacBook you have. All Apple computers are limited to a minimum (or oldest) OS version that can be installed on them. So for example...if a MacBook model was released in "Late 2009" the oldest OS version that can be installed on it would be a version of OS 10.6 (OS 10.5 wouldn't work). Also...even if your MacBook is "old enough" to install OS 10.5 on it...those gray/silver disks from an older iMac will not work on it. Those gray/silver discs are model specific...so gray/silver iMac disks will not work on a MacBook. HTH, - Nick [/QUOTE]
