The M.2 to Mac SSD Converter for the 2017 MacBook Pro A1708 refers to an adapter or conversion kit that allows you to install an M.2 NVMe SSD into a MacBook Pro that originally uses a proprietary Apple SSD. However, it's important to note that MacBooks, especially the 2017 MacBook Pro A1708, use a custom SSD connector that differs from standard M.2 NVMe or SATA connectors.

Here are some key details to consider:

1. MacBook Pro A1708 SSD Specifications

• The 2017 MacBook Pro (A1708) typically comes with a PCIe-based proprietary Apple SSD that is not compatible with standard M.2 SSDs directly.
• The SSD is soldered onto the motherboard in many MacBooks (including certain configurations of the A1708), making upgrades or replacements more difficult.

2. M.2 SSD Compatibility

• M.2 NVMe SSDs are common in modern laptops and desktops, but they are not directly compatible with the Apple connector.
• An adapter like an M.2 to Apple SSD Converter (if one exists) might allow you to use an M.2 SSD in your MacBook by converting the M.2 interface to the one used by the MacBook’s SSD connector.

3. Adapter Options

• Some companies sell M.2 to Apple SSD adapters or converters that let you use a third-party SSD, but it's not guaranteed that these adapters will work with every model of MacBook.
• Compatibility could be an issue because the firmware and macOS software often need to recognize and support the third-party drive. Some adapters may require you to install additional drivers, and even with the adapter, macOS might not support the drive natively.
