I have a new iPhone 8 (running iOS 12) and I want to connect it to iTunes on my MacBook Air (Late 2010), but when I connect them using the Lightning-to-USB-cable I get an error message saying the software on my Mac should be updated.
I found that I had OSX 10.10 Yosemite installed, so I used the Mac AppStore-app to upgrade to macOS 10.13 High_Sierra. That went smoothly, so I also installed all available updates for my apps from the Mac AppStore. Then, I ran into a strange error : I can’t upgrade to the newest version of iMovie because my version of macOS doesn’t meet the minimal system requirements…
I also ran iTunes, but even now my iPhone 8 isn’t recognised when I connect it…
I found that for some reason macOS 10.13.4 is installed, and not 10.13.6, but still : Mac AppStore says “no updates available”…
Is my MacBook Air late2010 not meeting the minimal system requirements for macOS 10.13.6 for some reason ?
I looked up my MacBook Air late 2010 in MacTracker, and found that is should be able to run macOS 10.13.6 so why won’t it install ?
How can I fix this ?
For reasons unknown, you need to upgrade your MacBook Air to macOS 10.13.5 manually using this download :
download macOS 10.13.5 upgrade
And only after macOS 10.13.5 is installed, you can manually upgrade to macOS 10.13.6 using this download (this is an incremental upgrade, not a combo upgrade) :
download macOS 10.13.6 upgrade
After macOS 10.13.6 is installed, you should be able to update to the latest versions of iMovie and iTunes via the Mac AppStore.
If iTunes won’t update, you need to (re)install it manually, using this download :
After installing the latest version of iTunes, connect your iPhone to your Mac using a Lighting-to-USB-cable. Now, an extra update will be downloaded, which will put an extra Devices-button in the iTunes and your iPhone will be recognised in iTunes.
That’s it !
