What is the best way to upgrade from 10.7.2 to 13.6? Would Apple's new Control + Option+ R that updates straight to the highest OS your device can accept work, or would I miss critical firmware updates and such? Any help would be greatly appreciated. Btw the gpu is fine, and I know the mods in case it fails. I'm going to leave it running till it fails. No plans for Mojave. Or should I update to Mountain Lion, then Yosemite, the Sierra then HS? I have the discs for ML, and Yosemite Mavericks, but they would need updated so no. If I need to update incrementally I'd most likely download from my 18,3 iMac and burn install discs on usb so I can retain the copies.
Thanks in advance.
