Upgrading OS on an old mac

Hi, El Capitan is the last OS X you can use with that machine.

You should still be able to use iCloud though, System Preferences > iCloud, make sure you sign in with the same Apple ID on your iPad and iMac.

OS X 10.11 El Capitàn can support the latest iTunes.

If you still want to store apps on iTunes locally, I would recommend install iTunes 12.6.3.

The current iTunes 12.7 no longer stores apps locally within iTunes any longer.

iTunes 12.6.3 download, located in this link, I believe still works with the newest iDevice models.

Good Luck to You!

There was a post about how to downgrade in the Water Cooler when iTunes 7 was first released.

See Managing apps with iTunes 12.7 or later. As well as installing iTunes 12.6.3 one should revert to a pre iTunes 12.7 version of the database. This can be found in the Previous iTunes Libraries folder, Time Machine, or similar. iTunes 12.7 should not have cleared out your Mobile Applications folder. Note that most newer apps will be app thinned versions that don't sync from device to library, so your library may not have held all of the apps you expected it to have. You can download your apps collection with iTunes 12.6.3.

Thanks. I have 12.7.2.58 iTunes. Do you mean i have to go backwards?

You’re too late to do this, now.

I have heard downgrading to an earlier version of iTunes was problematic.

So, if it is possible, I have no real idea on how to do the iTunes downgrade to 12.6.3.

I didn’t upgrade to 12.7 because I was holding out hope that Apple would do another update to iTunes 12.6 to still be able to support saving apps within iTunes locally.

So, I can't give you any other advice or procedures on how to performs this, if wish to downgrade iTunes back to 12.6.3.

Sorry.

Hi adamcig, the maximum OS that you can install on your iMac is OS X 10.11.6. To use iCloud, you need at least iOS 5 and at least OS X Lion on Mac. Hope it helps. Cheers.

Missed it.

I don’t frequent the WaterCooler enough to catch all of the postings going through.

If you have two different iCloud accounts maybe consider creating a second account on your Mac for the other iCloud account and iTunes.

That way you can have one account per device.

You need to sign into iCloud using the same Apple ID on both devices. Then turn desired syncing on.

I'm not sure I understand what you are asking, but you can only sign in with one Apple ID. You can't share all data with someone else signed into iCloud with a different ID.
