The iPhone “...” cannot be synced because there is not enough free space to hold all the selected items

When you start syncing your iDevice in iTunes and then you get this annoying message (especially when it tells you it needs like 1.4MB and there is 300MB available?!): 'The iPhone/iPad “iPhone(insert name)” cannot be synced because there is not enough free space to hold all the selected items'. What do you do?

Basically the problem, in many cases, seems to be that iTunes thinks it has too many updates to install on your iPhone/iPad and it isn't smart enough to load them one at a time when there's not enough space to do them all??

Fortunately it can often be side-stepped by just taking your iPhone/iPad and clicking on the App Store app,  then tapping on the Updates tab, and then tapping on 'Update All' at the top right. If that  complains that there's not enough space you can let do some updates then try again (and again) and will update the rest of the apps. Then the sync should be fine with iTunes.

How stop an iOS app from being upgraded by iTunes

So there's that app that you like the current version and newer ones just suck but iTunes doesn't make it easy to stop arbitrary apps from being upgraded. The problem with trying stop an old app from being upgraded is that it's all or nothing - you can either switch off automatic updates or you have to manually select the apps you want to upgrade every time.

The way to stop this is to change the permissions on the app so that it's can't be deleted (nor upgraded) by iTunes - first locate the app (e.g. /Users/test/Music/iTunes/Mobile\ Applications/Twitter\ 2.19.ipa ) Then you set the immutable flag on the app from the Terminal:

chflags uchg /Users/test/Music/iTunes/Mobile\ Applications/Twitter\ 2.19.ipa

When iTunes tries to update the app it tries to delete and replace it with the newer version but it fails ('Saying the original file can't be found'). But you can ignore that warning.

If you want to upgrade it at another point you'll need to just delete it and rerun iTunes so that it fetches the new version.


Note: That apps are unique to your user ID so you can't just copy an app (an .ipa file) from someone else an install it on your device, though you can with if you have older copies of an app for your device installed with that user ID.

Update:27nov15: Unfortunately it's not clear that this technique does stop iTunes from upgrading the apps in all situations;(

Update:23feb16: If this doesn't work you can copy the desired version of the app ipa file elsewhere and then delete the app from iTunes and then copy in the older version and sync again.

iTunes stopped syncing with iPhone?

The other day - as had happened a few times before - when I plugged my iPhone/iPad into my Mac iTunes failed to automatically start. Indeed iTunes didn't even seem recognise that my iPhone was plugged in - neither when directly plugged into USB nor when trying to 'sync over WiFi'. Another odd symptom was that my iPhone suddenly started to ask if I wanted to Trust this computer (that I have always synced to the past). A reboot had usually fixed this in the past but that's a pain so I snooped around for other answers - The usbmuxd daemon seemed to be complaining about weird stuff in the logs so I figured lets try and kill it! And low and behold that fixed the problem - usbmuxd restarted (probably care of launchd) and all was well again - iTunes saw my devices and wanted to talk to them again - a handy quick fix.

Here's the command line way to kill it - to be safe quit iTunes and unplug your iPhone beforehand:

sudo killall usbmuxd
