If your iPhone, iPad, or iPod touch won‘t turn on or is frozen

30/10/2017 Comments off

If your device has a frozen screen or doesn’t respond when you touch it, or becomes stuck when you turn it on, learn what to do.

If your screen is black or frozen

If your screen is black or frozen, you might need to force restart your device. A force restart won’t erase the content on your device. You can force restart your device even if the screen is black or the buttons aren’t responding. Follow these steps:

  • On an iPhone 8 or iPhone 8 Plus: Press and quickly release the Volume Up button. Then press and quickly release the Volume Down button. Finally, press and hold the Side button until you see the Apple logo.
  • On an iPhone 7 or iPhone 7 Plus: Press and hold both the Side and Volume Down buttons for at least 10 seconds, until you see the Apple logo.
  • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and the Top (or Side) buttons for at least 10 seconds, until you see the Apple logo.

If your device still won’t turn on or start up

Plug in your device and let it charge for up to one hour.

After a few minutes, you should see the charging screen. 

 

If you don’t see the charging screen within an hour, or you see the connect to power screen, check the jack, USB cable, and power adapter. Make sure that everything is plugged in firmly, free of debris, and not damaged. You might want to try a different USB cable or power adapter.

If your device still doesn’t turn on, see what to do next.

If your device turns on but gets stuck during start up

If you see the Apple logo or a red or blue screen during startup, try these steps:

  1. Connect your device to a computer and open iTunes. If you don’t have a computer, try to borrow one, or go to an Apple Store or Apple Authorized Service Provider for help. 
  2. While your device is connected, force it to restart. 
    • On an iPhone 8 or iPhone 8 Plus: Press and quickly release the Volume Up button. Then press and quickly release the Volume Down button. Finally, press and hold the Side button until you see the recovery-mode screen.
    • On an iPhone 7 or iPhone 7 Plus: Press and hold the Side and Volume Down buttons at the same time. Keep holding them until you see the recovery-mode screen.
    • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and the Top (or Side) buttons at the same time. Keep holding them until you see the recovery-mode screen.
  3. Don’t release the buttons when you see the Apple logo. Keep holding until you see the recovery mode screen.

 

  1. When you get the option to restore or update, choose Update. iTunes will try to reinstall iOS without erasing your data.

iTunes will download the software for your device. If it takes more than 15 minutes, your device will exit recovery mode and you’ll need to repeat steps 2 and 3.

How to Downgrade iOS 11 to iOS 10.3.3 on iPhone and iPad

06/10/2017 Comments off

Don’t like iOS 11 on your iPhone or iPad? You can downgrade to iOS 10.3.3 if you act quickly. Maybe you don’t like the update, maybe you find iOS 11 battery life to be poor, or app compatibility to be a problem, or perhaps you think the performance is subpar. Whatever the reason, you can easily downgrade iOS 11 if you need to, but the ability to downgrade is only available for a limited time while Apple continues to sign the prior operating system release of iOS 10.3.3.

We’ll walk through how you can downgrade iOS 11 back to iOS 10 on an iPhone or iPad.

This guide requires iTunes and a computer, internet access, an iOS 10.3.3 ISPW file, and a USB cable. There is no way to downgrade iOS 11 without iTunes and a computer.

Important note: downgrading iOS 11 to iOS 10.3.3 can cause data loss, including the removal of important data or everything on your iPhone or iPad. Thus it is critical to have a backup that is compatible with iOS 10 available before downgrading (one should have been made prior to updating to iOS 11 in the first place), this is because iOS 11 backups are not compatible with iOS 10 or other prior releases. If you only have a backup for iOS 11, then downgrading to iOS 10 may require you to update again to iOS 11 in order to restore from that iOS 11 backup. If you don’t know what you are doing and do not have adequate backups, do not attempt to downgrade or you may experience permanent data loss on the iPhone or iPad.

We’ll cover two ways to downgrade, a simple way that should work for most users, and an approach that requires Recovery Mode if the first downgrade method fails.

How to Disable or Enable Auto-Brightness in iOS 11 for iPhone and iPad

04/10/2017 Comments off

Auto-Brightness is a screen setting on the iPhone and iPad which causes the device to automatically adjust the display brightness depending on ambient lighting conditions. For example, if you’re outdoors or in bright lighting, the screen would adjust to be brighter so that it is more visible, and if you’re in a dim room or outdoors at night, the screen would adjust to lower the brightness so that the screen isn’t as glaringly bright. Auto-brightness in iOS also can improve battery life by adjusting the brightness of the iPhone or iPad display down as the ambient lighting permits.

How to set up iCloud services in Snow Leopard

28/01/2014 Comments off

Source: cnet.com by Topher Kessler

While Apple’s iCloud services are officially supported only in OS X 10.7 Lion or later, you can get some working in Snow Leopard.

iCloud is the latest iteration of Apple’s cloud-based services, and while it can be accessed from any Web browser, it requires at least OS X 10.7 to integrate into the Mac OS. Unfortunately this means that if you are on an older Mac system running Snow Leopard that you either don’t want to or can’t upgrade, then Apple no longer supports accessing its iCloud services.

Recently MacFixIt reader Brandon wrote in wondering about the options for people with these setups:

I just purchased an iPhone and am trying to sync my Mac devices, but have run into a problem. I currently have an iMac 4,1 version 10.6.8 with a 2 GHz Intel Core Duo processor. In order to sync my devices with iCloud, I was told (by Apple) that I need to upgrade to Lion, at least.

[How can I get iCloud on my computer?] My ultimate goal is to have my work computer synced with my iPhone synced with my MacBook at home. Can I purchase and install the Intel Core 2 Duo processor I apparently need [to run Lion]? Are there any ways around this issue? Perhaps there is a cheaper component I could buy?

Upgrading the iMac‘s hardware would theoretically be possible, except that Apple’s iMac systems are soldered together, making it impossible to perform tasks like upgrading the CPU. They also do not have any standardized expansion slots, so upgrading components like video cards is also impossible. Even if you were able to upgrade the hardware and get Lion or Mountain Lion running, the system would not have been tested and could have stability problems.

The only components that can be upgraded on systems like the iMac are the removable RAM modules, the hard drive, and the optical drive. As a result, in most cases a Mac system that does not meet the minimum CPU and graphics requirements will not be able to run Lion or Mountain Lion, regardless of what you do.

Therefore, the only supported method for accessing iCloud services on older systems that can only run Snow Leopard is to use Apple’s iCloud Web interface; however, there are ways you can set up programs like Safari, Address Book, and iCal in unsupported ways to access iCloud services and make use of them.

Do keep in mind that these setups may not be the most reliable, but you can use the following steps to get the services to work in Snow Leopard and test them out with your phone.

Mac OS X: Synchronisation AddressBook/iCal/iCloud/Google. L’impasse ?

28/01/2014 Comments off

Pour ceux qui ont eu la mauvaise idée de posséder un iMac, un iPhone *ET* un smartphone Android, se pose le problème de synchronisation des informations. J’en fais partie…

Est-ce que j’utilise iCloud avec mon iMac et mon iPhone et je reste planté avec mon Android chez Google Contacts?

Est-ce que j’utilise Google Contacts avec Android et j’utilise « Synchro avec Google » dans AddressBook et créer un compte GMail sur le iPhone?

Dans le premier cas, comment être certain que les contacts iCloud sont bien les mêmes que sur Google Contacts? Et réciproquement.

J’ai essayé le deuxième scénario: synchro stable la plupart du temps mais si on a le malheur de modifier ou effacer une fiche sur Mac OS X, la reprise d ela synchro crée un doublon, voire un triplon et pas forcément sur toutes les fiches, et pas forcément doublon plutôt que triplon, des fois plutôt sur les fiches « société » (sans nom/prénom) mais pas obligatoirement…

Comme vous le voyez, c’est pénible et ça enlève toute confiance dans une source (Google) ou l’autre (Mac OS X).

Une solution: SmoothSync for Cloud.
