Jun 09, 2019 Mac OS X 10.9.5 (Mavericks)one user has said is required for iOS 10 and iTunes 12.5. It is though unable to sync with iOS 11.Mac OS X 10.10 (Yosemite) is required minimum for the new iCloud Drive and iOS 11 (except for Notes, which requires El Capitan). ITunes 12.7.0.166 is needed for iOS 11.iTunes 12.8 is now available for 10.11.6 and later.

This tip is designed to be a one stop shop to find out what iOS you can use if you are able to install a specific Mac OS X.


Now updated for iOS 12. Including a method to downgrade to iOS 10.3.3, and a method of downgrading to iOS 11.4.


On May 29, 2019, it was found that iOS 12.1.5 could sync with iTunes on Mac OS X 10.10.5 if you kept iTunes 12.5.5.


This thread discusses more of the inconsistent requirements that were initially stated:


https://www.imobie.com/support/how-to-downgrade-from-ios-12-to-ios-11.htm offers a means of downgrading from iOS 12 to iOS 11, if no other means work to link an elderly Mac that can't be updated to 10.11. Be very careful to backup your data properly to avoid problems. Consider a lightning port data transfer device if you need to backup data. And remember no backup is complete, unless you know you have two working copies.

Downgrading Mac OS X is possible in many cases, but your iOS is not at all. Downgrading a Mac is described here:http://discussions.apple.com/docs/DOC-1948

Apple has this to say about iOS recognition:If your iOS 12 device isn't recognized by iTunes, you might need to upgrade macOS or iTunes - Apple Support

iOS 12 & Yosemite -is a new tip I constructed to cover what can be done for those with Yosemite when downgrading the iOS is no longer possible.

For iOS earlier than 5, see this tip:Which OS do I have and where should I post?So be sure to look this over before upgrading your iOS and backup/sync your iOS with your Mac:

Mac OS X 10.5.8 (Leopard) supports PowerPC Macs, iTunes 10.6.3, iOS 5.1.1.Mac OS X 10.6.8 (Snow Leopard) supports Intel only Macs, but does support PowerPC applications, iTunes 11.4 and iOS 6, and iOS 7.Mac OS X 10.7.3 (Lion) supports iCloud except for iCloud Drive in its current iteration and the new Notes.Mac OS X 10.7.5 (Lion) (link explains the pitfalls of losing PowerPC applications) supports iTunes 12.2.2.25 (available from Software update as of 10/24/2015), iOS 8 and iOS 9.0.Mac OS X 10.8 (Mountain Lion) is required for iTunes 12.3 and iOS 9.2 and iOS 9.2.1(except iCloud Drive, and the new notes). Does not support iOS 10 or iTunes 12.5.1 according to the Wikipedia below.Mac OS X 10.9.5 (Mavericks)one user has said is required for iOS 10 and iTunes 12.5. It is though unable to sync with iOS 11.Mac OS X 10.10 (Yosemite) is required minimum for the new iCloud Drive and iOS 11 (except for Notes, which requires El Capitan). iTunes 12.7.0.166 is needed for iOS 11.iTunes 12.8 is now available for 10.11.6 and later. I have waited for any confirmation of working 10.10.5 systems and it appears the system requirements are in error on the website for linking to iOS 12.

Mac OS X 10.11 (El Capitan) is required for the new Notes on iOS 9, and 10.11.6 for the iPhone XR, XS, and iOS 12 and is compatible with all Mac OS X 10.8 and later compatible Macs. It is available for download only for Macs with 10.6 installed and updated to 10.6.8.

Mac OS 10.12 (Sierra) currently has no special requirements as of September 23, 2017, however is a free path to upgrade from Macs that shipped with Lion, that upgraded to 10.7.5 or later, and then updated to Sierra to be able to synchronize with iOS 12.

iOS 12 was released September 17, 2018. Please make sure to backup your data on your iphone, ipad, or ipod touch and not apply any update until you are certain that iTunes on your Mac or PC can handle it.

Some may find running Windows on their Mac Running Windows on a Mac, and Connecting it to Macor creating a separate partition for a newer Mac OS How to format a drive, or disc for maximum portability?allows one to sync to a newer iOS without losing compatibility of older Mac OS versions.

Stuck in Mavericks, Mac OS X 10.9.5? There is a published way to downgrade your iOS.

Note: this is not for the faint at heart, but sure is better than having to upgrade your Mac OS X prematurely for an App you can't afford upgrading on your Mac.

The last iOS supported for various iDevices is listed on the table called 'Terminal update for' on:https://en.wikipedia.org/wiki/IOS_version_history

And many of the latest iOS versions and iTunes support are on https://en.wikipedia.org/wiki/History_of_iTunes

Notes: Upgrading to 10.7 and above, don't forget Rosetta! and High Sierra upgrading tipoffer two means of getting your Mac up to speed with iTunes 12.8. Use the first tip if running 10.6.8 or earlier to get to 10.11. And use the other tip if running 10.8 or later.

For any questions not answered here that require direct feedback from Apple iCloud support, please submit your inquiries to:



As iCloud has progressed, some of the links below were removed from the knowledgebase. If you find one that has, ask on the forum for iCloud

what user's experience has been.


Note to transition to Lion you still have to backup your data, but at least you now won't have to pay double for your upgrade to Lion,

as long as you have the bandwidth. Additionally, upgrading to Lion, Mountain Lion, and Mavericks (10.7 or later) will affect your compatibility of many applications:



Note that June 12, 2012, and June 30, 2012 several services were be shut down, and read carefully in the link above which of these may affect you.

Certain iLife applications work best with Lion according to


Apple explains how iWeb websites will be impacted in this article:

iWeb has never been completely compatible with all web browsers. http://www.anybrowser.org/ offers tips on making your website more compatible. http://www.barebones.com/ offers numerous tools to make it more compatible, including the free Textwrangler. Any web software development engine that at least lets you save as pure HTML without forcing code into your website will do the same thing.


Apple's transition to iCloud from Mobileme is outlined in this article:

http://support.apple.com/kb/HT4597 - note this link is an old archived version from the Wayback Engine that should help those

Ntfs 3g for mac sierra download free. wondering how things changed.


Which also explains the full assortment of system requirements for iCloud. What you can see is at least Safari 5, which is available for Mac OS X 10.5 can access some iCloud features. For a complete listing of what's supported and what is not in pre-Mac OS X 10.7.2, see:



Note: sadly at last look this article has been taken off the web by Apple. Please send Apple feedback to get it back up.


For migration tips from MobileMe, see:


For full iCloud support virtualization of Windows 7 or Vista is an alternative that some may wish to consider if one wishes to maintain PowerPC application compatibility that does not exist in Mac OS X 10.7. Note, you will have to choose a 32bit incarnation of either version of Windows unless your Core2Duo is also amongst the 64bit supporting Windows on this article:



Also if one has an Intel Core Solo or Intel CoreDuo, or a Core2Duo with under 2 GB of RAM, installing virtualization may be your only solution to use certain iCloud features since Lion won't install on anything less than a Core2Duo with 2 GB of RAM. PowerPC Macs won't install either Vista or Windows 7 on virtualization since they are too slow. Third party alternatives exist for them like Chronosync and numerous webhosts, including possibly your own internet provider if you wish to sync across the internet. Those upgrading to 10.7.2 for iCloud full support, should read this tip first:



Strictly speaking iCloud is not compatible with earlier operating systems, but it's possible to migrate and set Mail up in them.


You can migrate from MobileMe to iCloud at http://me.com/move even with earlier systems: when asked to confirm that your Mac is running Lion just lie and say 'yes'. Of course you won't be able to access iCloud directly from your Mac.


If you have MobileMe mail set up to collect mail from external POP accounts you should cancel this before migrating, or you may find it still working in iCloud (where it isn't supposed to) and with no way of stopping it.

This will be the situation with Snow Leopard when you have migrated:


  • Your email, calendars, and 'Find my iPhone' will be migrated to iCloud. Contacts and Bookmarks cannot be migrated from a Snow Leopard Mac.
  • Your iDisk, together with website hosting and Gallery, will continue to work as before until next June.
  • Syncing of Dashboard Widgets, Dock Items and Keychains between Macs, and Mail Accounts, Mail Rules, System Preferences, Signatures & Smart Mailboxes between Macs & iOS devices, will cease altogether.
  • You will be able to access email and calendars on the iCloud website at http://icloud.com provided your browser is reasonably up-to-date.
  • You will not be able to sync contacts or bookmarks from a pre-Lion Mac.
  • You will be able to enter the server settings for email manually in the Mail application and access your email.
  • You will not be able to sync your calendars directly.
  • Some people have been able to set up calendar syncing by using the method detailed here - this is an unsupported hack and may not be reliable, and may stop working at some future point.
  • There appears to be no method of syncing contacts (though Address Book on a Mac can be synced with Google or Yahoo address books - I don't know how reliable this is).


It's also possible to set Mail up manually on Leopard and Tiger but it's not possible to sync Calendars or any other data with iCloud using them.


There are a couple of third-party solutions which may be of interest.

BusyCal is an iCal-like calendar application with extra facilities: it can sync with the iCloud Calendar while running on Leopard, Snow Leopard or Lion. A single user licence (two machines allowed) is $49.99. I've been made aware the latest version of BusyCal does not support anything earlier than 10.7.2. I would contact the author to determine if you can still use an older version without their support or not.


Soho Organizer can sync Calendars and Contacts with iCloud on Leopard, Snow Leopard and Lion. A single user licence (multiple machines allowed) is $99.99.



I strongly recommend if you feel iCloud needs further support to post to:
