Before you upgrade to iOS 11 tomorrow

“Apple will release the highly anticipated iOS 11 update tomorrow Tuesday, September 19th 2017,” Terry White blogs. “However, unlike previous iOS updates this one is likely to leave some of your apps behind.”

“Moving forward iOS will only work with 64bit enabled applications. iOS has grown and a 64bit architecture is a good thing,” White writes. “As iPhones and iPads continue to add more RAM these newer applications will be able to take advantage of the newer hardware.”

“Currently in iOS 10.x Apple has been warning you all along about apps that may not work in iOS 11,” White writes. “When You launch one of these older apps you sometimes get a message that states: ‘“This app will not work with iOS 11. The developer of this app will need to update it for compatibility.’ Other than those occasional warnings you can actually get a list of which ones iOS 11 will leave behind. Launch your Settings App and tap General->About->Applications to see your App Compatibility List.”

MacDailyNews Take: Before installing iOS 11, back up your iOS device(s) first!

How to back up your iPhone, iPad, and iPod touch here.


  1. Didn’t an earlier article claim that iOS 11 does not backup apps? Does it restore those apps from an iOS 10.x backup? If it does not backup apps, then it likely won’t restore them from a backup.

    Result… you’ll have to re-download them all.

    The nice thing is that Apple’s OS upgrades are almost always 10% of the hassle of a Windows or Linux upgrade and seldom lose your apps or data in the upgrade — but it does happen.

    So, as MDN says, do a FULL backup to your computer before attempting any upgrade.

    Unfortunately, I routinely use a couple 32-bit apps that have been abandoned by their developers. Now I’ll have to spend some time finding replacements.

    1. The new iTunes does not make a backup of the actual app files on your Mac, if that is how you do stuff (I do). It makes a note of what apps are on your device, and backs up the data, but not the actual app files like iTunes 12.6 does. So if you need to restore your device later all of the apps will have to re-download from the app store. If they are still there. Lucky us. I won’t be going beyond iTunes 12.6 and iOS10 for a long time. Non-high Sierra, either. Apple is out of control.

  2. Has Apple ANYWHERE, explained how to manage apps with the App Store removed from iTunes 11?

    This going to be an even larger issue as people are forced to upgrade with new phones or they upgrade to iOS 11.

    1. I upgraded a few days ago, there are some bugs but nothing terrible, for me at least. The Podcast app “update” is clunky and un-user-friendly. I accidentally deleted a podcast and all the saved episodes from my library (no warning prompt) and now I’m trying to figure out how to get them back. Not the end of the world but I’m noticing more lag on my 6+.

  3. Been running iOS 11 beta. Pretty cool, some bugs even the day before release. Attention: Ray Donovan will not play on iOS 11… I repeat Ray Donovan will not play on iOS 11… carry on.

  4. Yeah be careful with this upgrade. I’ve been playing with the beta for a few weeks and got burned.

    I strongly suggest having multiple backups of important files, docs, pictures, videos, etc that you care deeply about. Don’t simply rely on a single backup strategy (say Time Machine for instance).

    Without going into a lot of gory details, I wasted hours because a file in the new Beta MacOS got corrupted and ALL of my Time Machine backups were corrupted as well. Had to end up repartitioning my drive, and going with a fresh copy of Sierra. Thank god I had backups of stuff on other drives and clouds so getting restored wasn’t a catastrophe….just time consuming.

    Murphy’s Law will strike when you least expect it.

  5. My iPad Air 2 coasted through the whole Public Beta process without any problems, so I’ll just continue using it as it is now. My iPhone 6+ is a whole different story. The PB made it slow and unwieldy. The iOS Gold Master only improved things marginally. So when the dust settles a bit I’ll do a nuke ‘n pave on it to see if it can actually cope with the latest iOS. There is just one file on it that is worth saving manually, so it’ll be not too much trouble.
