Mac App Store not Downloading Updates

I have the same issue, and it's not limited to iTunes. All of my software updates, including those for third-party apps have this issue. I will click "update" it'll gray out and then, after a restart, it says it was updated, but it wasn't. Now, when click update (they are now both in the need to be updated and recently updated lists) it'll flash "installing" for a second and then go back to having the update button and it will be added to "recently updated" again. At one point I had an issue where I would click update and it would have a popup saying something about downloading and restarting after the update was finished, I would click download & update and then immediately the restart warning would pop up, and I would tell it to restart later. After doing this for an update, the notifications would stop and it would just flash the installing bar as mentioned previously. I clicked the "not now" option on one of the pop-ups and now they don't show up and neither do the restart notifications and it goes straight to the installation bar flash, (which svcks because I wanted to try restarting using the notification for update installs instead of the standard way to see if there were any changes). I got 12.2 for iTunes by downloading off of the Apple website http://www.apple.com/itunes/download/ as per someone on another form recommended, and a few f the third party apps have their own unique update app that will probably work, but for the majority I have to use the App Store and I can't so I'm stuck.

Bonjour,

J'ai le même problème.

J'ai trois applications à mettre à jour : iMovie, OneNote et Garage Band plus iTunes dont la mise à jour a été annoncée dans l'app elle-même.

Les mises à jour ne se téléchargent pas : Le Mac App store cherche les nouvelles mises à jour et reste bloqué.

J'ai un iMac 21,5 équipé de Yosemite et OS X 10,10.3.

C'est agaçant, ça fait plusieurs jours que ça dure !

Plooom,

Premièrement, pardonnez mon français mauvais s'il vous plaît; Je ne suis pas très bien.

Mais, pour iTunes, la solution est à aller au site web pour Apple: http://www.apple.com/itunes/download/, et télécharger à partir du lien il. Il téléchargera une image de disque qui vous pouvez ouvrir et aller par le processus à installer iTunes 12.2 et à effacer le ancienne version de iTunes.
