can i install any osx on my imac after changing hard drive

[Phantom_35]

im planning to replace the hard drive in my imac 2008 which is currently running el capitan 10.11, i was wondering if i could install mac os mojave which i have on a bootable drive?

[SupaKomputa]

If it supports mojave, yes why not. But i think it's not supported.

My Early 2008 got to El Capitain and has never updated further. Try eBay for a universal installer disk. What are you replacing your drive with? Sticking with a spinning platter or moving to an SSD?

Even with an SSD it may not be worth it. I had a 2008 Mac Pro (dual xeon CPUs) and used a patched installer to get the latest OSX on it, and it was still slow. You would be better served with a linux variant. (Elementary gives a very nice MAC like look and feel.)

Thanks for the response, the Mac we’re talking about has 6gb ram and an upgraded gpu ( I didn’t install it so idk which one ) and I’m trying to install an sshd. Also it was pretty fast even before all my upgrades which I did only 5 months ago. So with a patcher I could get Mojave but will the patcher work on a new storage thing? Also for some reason I can never seem to boot off a usb or even find one when I hold option key so is there any way I could preload it on to the sshd with my laptop?
