Update for anyone using Mojave I recommend either going back to high sierra or using something like opencore and upgrade, after mostly finishing up installing Monterey on mine it runs faster and smoother than Mojave.I can confirm this I swapped out my gpu on my ’12 cmp (fan was dying anyways and was getting annoying) and Mojave installed no problem, as far as newer os’es that requires some special patching
also I can also confirm iOS 16.5 works on itunes even dfu’ed and updated my iPad to 16.5 using iTunes plus every time I jailbreak my phone or pad iTunes pops up all the time to tell me my device needs help
