Updating macOS on an MBP Late 2011 to Support iPhone 12

If your MacBook Pro (Late 2011) running macOS 13.7 prompts you to update the software to connect your iPhone 12, it’s because newer iPhones require updated macOS versions or at least the latest version of iTunes (or Finder) to communicate with the device. Since macOS 13.7 (High Sierra) is outdated, here’s what you can do:

Solution 1: Update macOS to the Latest Compatible Version

The Late 2011 MacBook Pro officially supports up to macOS High Sierra (10.13.6). However, using OpenCore Legacy Patcher (OCLP), you can upgrade to newer versions like macOS Catalina (10.15). Catalina supports the latest iTunes and Finder compatibility with iPhones like the iPhone 12.

Steps to Update to macOS Catalina (OCLP):

1. Download OpenCore Legacy Patcher:

   • Visit the OpenCore Legacy Patcher GitHub page and download the latest release.

2. Create a Bootable macOS Installer:

   • Download macOS Catalina from Apple’s support site or another trusted source.
   • Use the createinstallmedia Terminal command to create a bootable USB drive.

3. Install macOS Catalina with OCLP:

   • Follow OCLP’s guide to patch your system and install macOS Catalina.
   • Once installed, your MacBook Pro will have support for Finder/iTunes compatibility with iPhone 12.

Solution 2: Update iTunes on macOS High Sierra

If upgrading macOS isn’t an option, try updating iTunes to the latest version supported by High Sierra:

1. Open the App Store and check for any system or iTunes updates.
2. Alternatively, download the latest iTunes version for macOS High Sierra directly from Apple’s iTunes Download Page.

Why This Might Not Work:

Newer iPhones like the iPhone 12 often require features or compatibility only available in more recent macOS versions.

Solution 3: Use a Different Mac or PC

If your Mac cannot be upgraded:

1. Borrow a friend’s or family member’s newer Mac or PC.
2. Connect your iPhone 12 to the updated system, and perform any required software updates or backups there.

Solution 4: Update iPhone Without macOS

You can bypass the MacBook entirely for updates:

1. Update Directly on iPhone:
   • Go to Settings > General > Software Update on your iPhone.
   • Download and install updates directly from the device.
2. Use iCloud Backup:
   • Back up your iPhone to iCloud instead of relying on iTunes or Finder.

Recommendation

For the best compatibility and user experience, upgrading your MacBook Pro with OCLP to macOS Catalina or beyond is the most robust solution. This will allow seamless updates and backups for your iPhone 12.
