What disk do I need to reintsall osx on my pre owned (mid 2007) imac?

Imac

Specs: 2.4ghz Intel core 2 duo

Software: Mac os x lion 10.7.5


I tried to do a factory restore on my mac as I plan on selling it. I followed the steps and erased the hdd, but after doing this it would not allow me to reinstall osx lion.


Do I need to purchase a disk to install a previous version of osx as I'm not the original owner?

And if so, what disk do I need?


Someone please help me! 😭

The original install discs that shipped with the computer. If you don't have them you need to call AppleCare, what I'd do is buy this DVD Mac OS X 10.6 Snow Leopard - Apple and follow the steps in What to do before you sell or give away your Mac - Apple Support, install 10.6. from the DVD then upgrade to 10.6.8 using Mac OS X 10.6.8 Update Combo v1.1 and then upgrade from there. This all assumes the computer has adequate RAM (4-6GB) and is in excellent mechanical shape.

Ok.


So to confirm;

I need to purchase and install snow leopard 10.6 and then upgrade to 10.6.8?


Also, I just realised I forgot to sign out of iTunes before erasing the hdd. What affect will this have?


Thank you for your time

Correct!


On the iTunes account, you are limited to 4-5 devices (I don't recall if it's 4 or 5..iPhones, iPads, Macs, etc..) per account so if you forgot to sign out then you have 1 less device you can use.

I've finally got around to purchasing the disk and started the installation process.


I restarted the machine with the c key held down (which took 15 mins) and now It will not let me select the Hdd to install osx.

I can't upload a picture to this but it reads;


'mac OS X cannot start up from this disk' and there is also a yellow warning sign on the image of the hdd ⚠


There is no other disk to select and I don't know where to go from here. Please
