But I wanted to make a reference document both for myself and for anyone else who might need it. Normally I have handy tips and tricks for the average user. This blog entry is a little different from my usual. Update 28-June 2022: Added information about macOS Ventura and recent computer models. Update 30-June-2021: Added information about macOS Monterey and recent computer models.
Update 12-July-2020: Added information about macOS Big Sur and recent computer models. So I know the machine is functional.I may earn a commission on purchases made through links on this page. I’ve also booted Ubuntu Linux on USB successfully. I’ve used the same technique to successfully install Snow Leopard on two older MacBooks (mentioned above). Here’s a small google photos album for reference. I don’t want to give up on it since it’s such a lovely machine. Nothing seems to let it get past this screen. I tried installing Leopard (10.5 via CPU Drop-in DVD). I’ve reset the NVRAM/PRAM more times than I can count. As soon as I hit Enter, the screen changes to the Apple logo screen (with nothing else, no progress meter, no spinner). It then, as expected, shows me the only option which is to boot the Mac OS X Install DVD. Then I installed a hard drive into the MBP, held down the Option/Alt key to boot from the USB drive. I have it on DVD and I have imaged it to a USB stick with Disk Utility to make for easier installations. I purchased a retail copy of Snow Leopard. Apple MacBook Pro "Core i5" 2.4 15" Mid-2010 Specs I also confirmed that my MBP is compatible with Snow Leopard.
But most folks with this issue have the original, still working HD to work with. I searched the Ask Different postings and did not find what I was looking for. I have successfully done this using the same process on two older MacBooks (A1151, A1181). I am trying to install Mac OS X Snow Leopard (Version 10.6.3). I purchased a used MBP (without a hard drive).
